It's been a while since I built a system from scratch and have a... errr... simple question

gfx: Sapphire HD3850 512MB Ultimate (passive)
http://www.sapphiretech.com/us/products/products_overview.php?gpid=225&grp=3

MB: MSI P35 Neo2 FIR

PSU: Seasonic M12II 500W
http://www.seasonic.com/product/pc_retail.jsp

The motherboard has a power connector for the graphic card next to the slot.

Is there any reason I should connect the power for the card to the power connector on the board instead of directly to the power supply?
 

A:Graphic card power to power supply or connector on motherboard?

First time I have ever seen that feature. I like it. I'm thinking that is a neat/easy way to partially eliminate cable clutter from the PSU. Give it a shot, you can always revert to PSU cable if you wish.

I know of at least three types of power supplies which have different connectors. The square one is for the new high Pentium mother boards. One has a connector with 20 pin (two rows of 10 each). The other has two connectors with a total of 12 pins (6 on each connector. Is the latter for an AT board? If not what power supply would I get which has the latter connectors.
Thanks.

Hi,  I have a HP Envy 700-509C and I replaced the graphic card. However, I bought another power supply (Corsair CX 600 : http://www.newegg.ca/Product/Product.aspx?Item=N82E16817139028&cm_re=corsair_cx600-_-17-139-028-_-Pr...) because the graphic card requires more power. I ran into a trouble, the last part was the 4-pin connector on the motherboard. There was no cord with only 4-pin, however there is a 8-pin connector and it says CPU on it. I tried it and it does plug in but there the other half (4-pin) hanging out. My question is, will it burn my motherboard? If no, will the computer work?  Thank you 

A:I want to change the power supply, but can a 8-pin connector...

@Kevin828, welcome to the forum. If you look at the "Specifications" in the link that you provided, you will see that it lists a 1 x 4+4 - Pin - ATX12V connector.  This means that you will use one of the 4-Pin connectors only. Please click the Thumbs up + button if I have helped you and click Accept as Solution if your problem is solved.

We're replacing a power supply on a gateway computer - the one that is in it and bad has a 4pin square connector that connects to the motherboard but we don't know what it is powering.

The power supply we are putting in it for the moment is an older one we're pulling from another puter and doesn't have that.

My motherboard has a 24 pin connection and I got a power supply with a 20 pin connection. While I'm waiting for my order of 24 pin connection power supplies, I realized that the 20 pin can fit in the 24 pin motherboard. Will I blow anything or cause harm if I power it up with the 20 pin power supply in the 24 pin connection of the motherboard?

Did I use the correct terminology? I am still learning. Thanks in advance.

Currently, I turn my computer on, and nothing happens, except green light on mother board and yellow light on computer "On" switch. I started testing power supply. That obviously works. I disconected everything from power supply and started to reconnect everything one by one.
Everthing seemed to allow the test switch on power box to power everything except when i came to connecting the 2x2 auxiliary atx 12v power connector (P9), into the mother board. It quickly shorts everything out, and i'm back to square 1 with just having the yellow "on" switch and green light on mother board, and fans shut off again.
Whats the problem?

I have a 500s 1.5 hertz gateway

A:Connecting 2x2 connector from power supply into motherboard shorts everything out?

If you don't own a power supply tester take your tower to a local shop and have them test the power supply. Even if the power supply tests good, have them "jump" a known good power supply to the board and see if the problem continues.

I have people bring towers in quite often for testing. It takes 20-30 minutes and the cost should be minimal perhaps $25-$30. You need to find out if your problem is with the power supply or the motherboard.

There is a 20 pin connector that would normally plug into a motherboard. Are there 2 pins in that connector that I can short so that the power will come on right away when plugged in?

Toshiba Satellite L305-5955, Ive taken apart and replaced power jack. Not directly soldered to motherboard. While still apart, and battery out/in, connected power supply and still absolutely no response. Power supply is NOT original, and slightly different specs, i.e original 19v..6.3A

current 19v..3.1A
 

A:Toshiba Satellite L305-5955 does not respond to power supply, new power jack

Almost certainly the problem is that the current rating is wrong, if the laptop needs
6.3 A of current, it won't function on less (just as you can't use a 3A fuse for a kettle!)
Unfortunately it must be the right current rating, I know, I've been caught that way too!
Maybe you can exchange it?

if I read the specifications right on your mobo... it implies that it has the 4 pin PCI-e input(power) but it also has the 8pin ATX power conector. (it may be simply removing a cap that is actually right next to the 4 pin connector, thus making it an 8 pin connector (thats how it was on my mobo)

Try using the 8pin power with your new PSU, see if that works.

Hi,
I picked up this Alienware 5700 off ebay to hopefully refurbish for my son but I'm new at this and still learning and so this thing has me baffled. The laptop is in pristine condition but shows no signs of life. When I plug in the power supply the green light on the power supply goes from solid green to blinking rapidly to the point you can barely see it. To me that would mean a short somewhere right ? If so where ? Has anyone else ever had experience with something like this ? I just don't want to go buying a new battery for a laptop that maybe fried already. Any help would be greatly appreciated.
 

A:No power, no lights but green light on power supply blinks rapidly

Remove the laptops battery and try the AC power only. If the green light does the same, it still could only be a bad AC adapter, or at worst, a shorted laptop motherboard

I have a Dell 8600 about two years old. When I plug in the AC adapter, it intermittently fades to the battery as though the plug was pulled out (its not) and of course the screen fades in an out when every time it swithces--it does it every 30 to 60 seconds or so. I switched to a different AC adapter (I have a Dell 600M with the same AC adapter)-same thing so I know it is something internally. Any ideas?

Sorry I don't know the proper terms, but basically the pin inside the jack where the power cord gets plugged into on my laptop was bent so that it's really hard for me to plug in my power cord and have it stay in place. My warranty with best buy has expired, so I need to figure out how to solve this problem on my own. I can't just leave it like this because the cord comes out really easily and I can't continue to work with such a tenuous setup. Anyway, is this just a matter of replacing the entire unit inside my laptop? I know you probably need more information, but I'm not sure what to provide, so please ask any questions. The laptop is a Toshia M-45, about 3-4 years old. Thanks in advance

Hi, I just bought an HP pavilion e9300 a few week ago. And I am going to upgrade the power supply so that I can get a new graphic card--ATI 4870 which requires at least 500 watt power supply. My current computer is shipped with a 350 watt power supply. I will probably get a 650 watt considering the 70% effeciency of power supply.
However, when I talked to an HP technician, he insisted that I could go for a power supply with no more 450 watt. Because the system I just got has a motherboard which has a max power limit 450 watt. He said if I go beyond that, the motherboard will burn out.
So what shall I do? I really want to get ATI 4870 work well on my computer.
Thx very much.
 

A:Does power supply with higher power rating really burn motherboard?

The long answer is "No".
Just be sure of the dimensions of the power supply before you order a replacement, as HP uses some pretty strange sizes sometimes, and you want the new one to fit with room to spare.

I have a Sony VGC-RB42G computer. I recently moved my computer, cleaned off all the dust, and when I plugged everything back in, it won't power up. The light on the power supply blinks green, inside the motherboard also has a green light that blinks as well. It has a ticking sound too, but I am not sure if it is coming from the power supply or the motherboard. Any idea what could be wrong.

FYI, I have already unplugged everything from the power supply, pulled out the ram, checked the battery, and put everything back together and still no change. One thing I thought was strange was after I unplugged everything, I pulled the power into the power supply again and this time the green light came on but did not blink. It stayed solid.

As you did not mention any message or display on the screen, I would use this tutorial for a step by step diagnostic.  It also helps to remove the side panel, and visually watch the CPU and rear case fan movement(s).  As you press the power button, pay attention to the fans. Also does the Power Supply LED stay ON? Or did it go OUT when you pressed the power button?

Ok so lately I have been getting a BSOD at very random times and it looks like a Diver Power State failure. SO all of my friends and every website I go to makes it seem like I need to get a PSU. Right now I have a Quad Core and a 8800GT and 375W PSU. So my friend told me to get a new 700W PSU.

So, if the only fix is to get a new PSU? I tried to rollback my GPU driver but it didn't help.

So any ideas?

Hey, got quite a problem with my laptop.. It's a Medion Erazer X7813, worked well for ~2 years.
I was doing a graphics card benchmark yesterday and it stopped in the middle of it(monitored temperature, it was at ~80 degrees Celsius when it turned off). No bluescreen or anything just off and I couldnt restart after that(no fans nothing). I thought it might be the power supply, so I tested it, but it was doing 19v when not plugged in, but when I plugged it in and unplugged it again it was at 1v. When testing I unintentionally shorted the power supply and it showed 1v after that just as it did after plugging it in, is it shorting inside the laptop? Could it be the battery or something more serious like the MB? Any ideas are welcome!

A:Computer won't power up after disconnecting power supply

While installing the new optical drive, you might have inadvertently loosened one or more connectors. Recheck all data and power cables to make sure they are tight, including all those to the motherboard.

My power supply died a few days ago and I have replaced it. My PC will now boot but will not send a signal (turn on) the monitor. Everything on the PC seems to work but it just will not turn on signal to the monitor. I have tried two different monitors with the same result.

Help!?!?!

was watching dvd and pc cut out completely... high pitch beeping comming from my power supply on hp 110 desktop... when i unplug from tower beeping stops .. plug it back in and it resumes.  No power, no flashing leds ... just constant beeping... no pattern ... just beeps continuously.

A:constant beep from power supply... no power to pc at all.

let me be clear.... beeping not coming from tower.... it comes from the plug in power supply... the square box part of it.

A:Power Supply Question & HD Power Consumption

Power Supply Question & HD Power Consumption, Pt. 2 - Laptop vs. 3.5"

My second question is this - I have a BTV server that needs to be on at all times during the season to record shows during day and evening.

Suffice it to say that you CANNOT reliably put one of the critters into sleep/hibernate mode and expect it to wake up and reliably record a show. It just won't happen.

Now, this is one case where I can use "Green" 3.5" drives, but I am also considering banking 500GB 7200RPM or even 5400RPM laptop drives. These will all be on a raid controller, but since they will be in pass-thru mode or RAID 0 mode the controller won't freak over TLER like it would with RAID 5/6 and mark the drives bad. The controller also has more than adequate cache to handle a 5400RPM spindle as OTA HDTV generates little more than 2.5MB per second per channel. Even 4 channels at once is 10MB/s and that should not tap the ability of a 3Ware controller with cache on 5400 RPM RAID 0 or even pass-thru drives.

My question is this - 2 500GB laptop drives burn much less startup and idle current than a single 1TB 3.5" drive. Has anyone tried running multiple laptop drives on a RAID controller, and what sort of luck have you had? What sort of sustained throuput can you obtain?

Electricity is a huge factor here, at 12 cents per KWh. I can recover the marginal cost of 2 500GB laptop drives vs. 1 1TB 3.5 drive.

Case construction and drive cages are not the issue here.

A:Computer won't power up (poss. power supply)

Does it happen with any other appliances? as in does using the toaster while using the kettle While your mate is in the Electric shower, telly on, or ironing?

Possibly a static build up, it is possible, Wher are you situated??
What voltage are you on?

What is the make and model of your comp? is it the same as your friends?

is your machine custom built or is it a brand?
Answer a few of them and we will try to narrow it down 4 you..

Mean while if you could get your hands on a spare PSU that would be handy. And remember when dealing with PSU's alway leave them to sischarge for at least 24hrs,
the 3 D'S, Disconect, discharge, dismantle.

A:New Build no power-up: case's power supply or MB?

Well, I figured out the problem.
I am planning to re-do the older mini-itx system I have; it has gotten riddled with Trojan software for kids downloading games; it basically has been de-commissioned already.

So, I took the pico-psu power supply from that older computer, and hooked it up to the one I am making. Everything went perfectly.

So, I un-did that, removed the MB from case, disconnected the barrel-power connection from the case, unscrewed and removed the power supply that had been mounted in the case, put the pico-psu power supply back in place (I had to drill the hole for the barrel-connection out to be a little bigger since the pico-psu internal/external connection is threaded and held in place by nut with lock washer), and routed wires to be clear of cpu fan, screwed MB to stand-offs, and closed it all up.

now, everything is great. I like this linkworld case, but the power supply is worthless. I may try to get a few dollars back from the ebay vendor, to make me happy with a case that is less than what I should have gotten, but is working for me; I don't want to wait on returns, etc.

A:New power supply, no schematic, looking for power fan plug.

There are basically two voltages available to you: 5V and 12V. Doesn't really matter where you get it from - some pin on the mobo or some wire from the PSU.

From the PSU the yellow wires are 12V and red ones 5V, black is ground. The fan voltages should be written on the fan itself, the black fan wire is ground, red may be 12V or 5V depending on the fan voltage.

Fan headers on the motherboard should be labelled so, check with a voltmeter what pin gives out what.

I have a generic MB (P-120 CPU ) which I just switched to a different case and power supply. It has an extra "six pin power type connection" in the middle of the board. Only one supply that I have matchs this and the wires are three green and three black. What is the funtion of this connector, it looks from the wire colors to be some form of switch.

Its a case of not wanting to swap out the power suppy from my other unit unless necessary. I have 4 other supplies and none have the extra wire, which is listed as P10.

Many thanks in advance.

Sounds like typical extra +5V lead and can be used for any number of things...(riser cards,backplanes,to drive extra slots, etc.)
Without knowing the specs. on your motherboard this question is impossible to answer...Post Mobo identification (make/model) or obtain FCC ID and post that. Perhaps we can find a more definitive answer for you...BOL

My PC suddenly shut off and wouldn't turn on, but the mouse and motherboard lights were still on. A tech took my PC and ran some tests. I assumed that either my Power supply or my Motherboard was unfunctional but he called me back telling me that it was neither, and that the problem was coming from "a part" that gave power to the motherboard. The replacement of this part would cost $80.

Am I getting ripped off? What part could possibly cost $80 and isn't the Power supply?

I have a Delta DPS-150GB B Power Supply out of an Apple Macintosh Power Mac computer. I would like to use it as a 12v/5A power supply for my model train layout. I have a couple important questions:

1) I need to know the pin-outs of the connectors (1-4pin, 1-14pin, 1-5pin on ribbon wire), specifically which ones control start-up and various voltage outputs.

2) Being a Switching Power Supply, I think there must be a load on at least one of the output rails. Can I create this with a simple resistor of some sort? if so, how exactly what would I need to do.

I can email photo of the connectors if that would halp. I would appreciate any help. Thanks.

I reckon a 500W wouldn't be enough but a 750W may be the right one. I had a look in a few forums and they had 650W & 750W etc but not 500W.

But wait for more input from the others and see what they have to say

A:Power supply and mobo are 100%, no power

There are some motherboards that have a power on button directly on the motherboard. I don't suppose you have one of those? There are some BIOS' that can enable the keyboard to power on the PC by pressing any key. I'm using one of them now. Of course, the problem with that is to get the PC started in the first place so you can change the BIOS setting (if it has that setting).

What motherboard do you have?

A:Power Supply - "The AC power adapter type cannot be determined....."

You are correct, the failure is due toloss of the power supply ID signal. Sometimes this happens because of strain on the plug, which breaks the signal wire. Some even are so severe that the insulation breaks away from the plug; this is due to rough handling. The other cause is one or more of the power socket solder connections to the system board become broken. This also is related to severe handling. I have seen one case where all three power connections and three of four mechanical connections were disconnected. If the power supply is bad, a replacement will cure the problem. If not, then the socket is bad, and this will require a system board replacement. If you are experienced, you can try to resolder the connections. I am experienced and was not able to get my daughter's E6000 to work by resoldered. More recent Dells are using a replacable power connection board which is a much cheaper repair.

hi guys,

i had a problem as my computer was switched off suddenly.after all the checkings i found that 12v atx power connector on mother board is not functioning.

case1: i tried connected both the 20pin and 12vatx pin and try switching on power nothing moves

case2: i tries connecting only 20pin on motherboard the power comes and fan on the proccesor starts moving. but if i connect both the pins on motherboard nothing is happening

so can anyone please tell me what is the problem and what i have to replace.

you're PSU might have blown.. Replace that first.

If its a crappy generic PSU, then it could have taken more than just itself out when your power cut.

My CPU's fan has a 4 pin power connector, however, my motherboard has no 4 pin power connector, it only has a 3 pin, any suggestions as to what i can do? Can i still use this 4 pin with the 3 pin or do i need to get a new fan/mother board?

The fan has a four pin power connector which must be looking like the power connector used to plug IDE HDD's or DVD/CD ROM's.
so just use one of those (which comes out from the SMPS)

And this MB: http://www.newegg.com/Product/Product.aspx?Item=N82E16813141005&Tpk=XFX+nForce+780i

I didnt notice that they were different if im looking at it right the PS one is only 4 pin and the MB one is 8. how do i fix this?
Also if the only option is to get a new PS (which i don't want to since i just bought this one) would the 4pin be alright since im only running a 6400 Core 2 duo, i mean thats all that the current MB uses is a 4pin. Or does the plug affect more then just the cpu?

Also will something like this work? http://www.newegg.com/Product/Product.aspx?Item=N82E16812145008

The title pretty much sums it up.....

My 500w psu only has one 6 pin power connector so im looking for the best graphics card that isnt over 9.6 inches long and only requires one 6 pin.

I would be willing to spend 150 if it got me a beast but as far as i can see anything more advanced than a GTS 250 seems to require 2 6pins.

Im looking at nvidia cards as the last Ati didnt work in my system and its irrationally put me off!

I am attempting to build a server and using a supermicro SC733T-450 case and a asus NRL-LS533 motherboard. When you look at the board on the asus site it shows a 24 pin power connector which is what I need for the server case.

However, I ordered the board from Mwave.com and it only has a 20 pin power connector. The manual shows a 20 pin connector also so why do they show 24 pin on the asus site? Did I get an older board or something? The specs on thier site also show a 24 pin connector http://www.mwave.com/mwave/SpecB/BA19507.html

So I guess I should return the board and get one with a 24 pin connector or could I get an adapter?

Thanks,

Doing a little upgrade to the PC I built almost a year ago. I wanted to try the new Sandy Bridge CPU, so I had to buy a new MOBO. I bought the Intel DP67BGB, it arrived today and I see it has an 8 pin power connector for the CPU. No adapters around town so I ordered one on the net. Anyway, I was told in a computer store today that as long as I wasn't overclocking I could run it with just one 4 pin . Want to make sure that's correct before I start rebuilding. Don't feel like waiting until next week for the adapter., but don't want to damage the CPU either.

BTW, the new CPU is Intel i5 2500, 3.3G.
 

A:8 pin CPU power connector

To be honest I wouldn't risk it. If too much power is drawn there is a chance that either the PSU, Motherboard, or CPU could be damaged and when you have spent that much on new parts it is worth waiting the extra week to make sure that you don't mess anything up. It may work for a while but in the long term it can't be good for the board/cpu/psu.

I`m trying to hook the power supply to the mobo but there is a 4pin Atx12 v connector and a 24 pin ATX connector. Now my power supply Corsair 750W TX only has a 24 pin power. Do I only need to plug in the 24 pin, or do I have to get some adapter for the Molex so I can plug the 4 pin ATX 12V?

Hi, I am tying to sort a PC for a friend. The PSU appears to be fried, so swapped that for a spare one. The spare provides power to the mobo in that the on board LED lights up, AGP powered fan spins up, as does the CPU fan and the case fan. However this is as far as I get, the is no video output. I am wondering if the mobo is fried too. One other thought is that the 20 pin connector on the original PSU contains 20 cables, whereas on newer PSUs there are only 19. Could it be that as the PC was built with a PSU which provided 20 cables into the 20 pin connector that a 20 pin connector fron a newer PSU which only contains 19 cables might not work? Sorry if this is a bit garbled.

what mobo is it? does it have an additional 4 pin power connector? or an additional 8 pin power connector?

Hi folks,

Hope someone can assist me with this one.....

I have a Packard Bell laptop and when i put in the power jack the connector on the laptop gets very hot after a few minutes.

It has even melted the jack on the power source a little.

Does this mean that the charging connectors on the mobo are faulty?

Anyone with information that can help would be greastly appreciated.

Thank you in advance.
 

A:Laptop power connector gets hot

General information: A conductor that gets overly hot is being required to conduct more current than the conductor is capable of conducting.

If this is the original equipment that came packaged with the computer, I suspect the wires have been flexed so much that some of the strands inside the insulation have broken, effectively reducing its conductive capability. This could be the source of the problem.

As an aside, I've never seen or heard of a Packard Bell laptop.

A:6+2 pin power connector into 8 pin socket?

Realistically you can use any 12v connections as long as they will fit in the socket, which is where you would find the problem.

The CPU connector is very simple:
12v 12v
GND GND
for the 4-pin
and
12v 12v 12v 12v
GND GND GND GND
for the 8-pin

By convention 12v wires are yellow.

Acceptable: get any four 12v connections to fit in the socket.
Better: Buy an 4-pin to 8-pin adapter (just a splitter, really)
Best: Buy a modern power supply. Your puter will love you for it!

Hello,

The problem is that I have to move the power adapter pin in various direction applying pressure in different angles until the blue ring lights up

Background:
Since 2007 I have already changed the power connector board twice. I have bought the board off ebay and changed it myself. The problem has re-surfaced once again.

Question:
Does anyone know if I can use any other type of power adapter board? I think the design of the recommended board (431446-001) is flawed and gets damaged very quickly.

I was gave a Compaq Presario laptop 12XL300 with a broke power connector. Could someone look at the images below and tell me where the the connector needs to be soldered. It seems someone had soldered it before but it had so much solder on it i couldnt figure out where it was broke so i tried to clean it off some.

laptop dc power connector protector

A tip for laptop owners. After trashing two Toshiba laptops due to continual problems with the DC power plug connection, I discovered a quick, cheap ($6) fix that is being offered on ebay. It won't repair existing problems but it will prevent future problems by simply removing the stress put on the DC cord that eventually cracks the solder on the mother board or prevents good contact within the connector itself. Suggest that laptop owners consider this to prevent an expensive repair later. It is adaptable to any laptop/notebook and can be viewed at ebay by querying "DC power jack protector".

A:PC won't start up with cpu power connector plugged in!

Something is connected incorrectly, or something has failed, such as a power supply.
Sever components, when configured incorrectly, will cause the fan to turn 1/4 to 1 turn when you press the start button, then quit because an error is detected in the hardware.

Hi, the power jack for my hp pavilion is on it's way out. I took the laptop apart yesterday and noticed that the power jack is connected to it's own seperate board along with a usb port. I was just wondering if anyone knows if theres anywhere that sell's those seperate boards on their own or if im going to have to solder on a new connector? Thanks..

Regards, Dave.

The computer store where I purchased my laptop in August has advised that the connector pin in my charger has broken and this has also broken the charging pin in the side of the laptop. The laptop will work when plugged in but will not charge. Surely this is a terrible design fault of the HP charger. Can anyone advice if this is repairable by HP?
