I have always bought seperate parts and built my computers myself. This time it did not work out. :) MSI P965 Platinum GeForce 8800GTX PCI-E 768M DDR3 Silverstone PowerSupply 600W Strider ST60F Basically, the computer powers up for half a second or so and then powers down. All the fans rotate except the GPU fan, which moves a millimeter or so when the power button is pressed and then stops. If I remove the GPU, it runs for a lot longer (say, 5 seconds) before it finally powers down. It also gives a loud beep. I guess this is because it detects that there is no GPU. This gives me the impression that I have problems with power, since it runs without the GPU. Any suggestions? I bought the Strider PowerSupply because I thought it would be able to handle the 8800 easily, but obviously I might be wrong.

All of the correct power connectors in place and securely connected? PSU set to the right input voltage? Do you have another graphics card you can drop in for testing?

Did you make sure all your cables are hooked up correctly? :) I ask because I'd switched some of the connectors inadvertently before, it can really screw things up. Did you also make sure you have the spacers between the motherboard and the case (yes, I made that mistake before as well). :D

All three power connectors (the ones that were marked with PCI-E) are connected. One into the motherboard (at the same spot as the CPU power cable) and two into the GPU.

This is my first PCI-E card ever, so I do not have anything else to try. :/

Spacers between mobo and case are there, and as I said the rig works just fine without the GPU. :)

I guess I am just surprised that 600W might not be enough! Sure, according to the manual the recommended amps are 26, and the PSU only delivers around 23. Makes me wish I had another PSU.

Nvidia states that 450W Power is minimum.


This site has an article, which worries me. The Power Supply reviewed works at 850W.

Quote: The SilverStone ST85F Power Supply has been giving BSOD's (Blue Screen of Death's - nvdisp) when using my system for everyday gaming. The nVIDIA System Sentinel also notifies me that my GPU is not receiving adequate power. I've tried to recreate these problems with another power supply, but the system remained stable. Score has been updated to reflect this issue. I suspect that it is not supplying clean or adequate power to the GeForce 8800. Other users of the ST85F have also complained about this issue, along with other issues (motherboard, etc.)

Edit: Nvidia also states that the 8800 requires 12V current with a rating of 30A. This chart hints that the Strider PSU only can deliver 18A maximum. Perhaps all those 12Vx combine for a total of 42A?

Confusing!

I got a similar message when I didn't have the pci-e connector plugged into pci express videocard before so make sure all your connections are secure.
Other than that only things I can think off top of my head are:
1.Cheap quality powersupply that doesn't supply as much power as it says. Plenty of reviews on web show that even with dual 8800 max powerdraw of 2cards is under 500watts so you should be ok but your rails current might not be enough and that's a different story.
2.Your motherboard,etc is grounding out somewhere.
3.Your cpu is overheating or your motherboard needs updated bios to support your cpu.

p.s. I keep an old nvidia pci fx5200 card just to troubleshoot these sort of things and it's saved me quite a number of times in the past from thinking motherboard kaput,etc. I think they still sell them for under $50 and it's a good investment if you are planning on building any more pc's or fixing them for anyone.

Most motherboards don't use PCI-Express for auxiliary power. They use 20+4 or 20+8 connectors.

Anyway, I don't think your PS is enough. For an 8800 GTX I would recommend something like a PC Power & Cooling Silencer 750 Quad to make sure there's enough current (it's actually certified up to dual 8800 SLI).

You might want to buy one of those, AND a $29 cheap-o GeForce 7300, to debug your system. First, try booting it with the cheap graphics card. Once that works, try the power-hungry monster. Compared to the overall cost of the PC, a $29 graphics card is probably like 1% of the cost :-)

I agree with trying a different PSU. The only time I've experienced what you're reporting is because of a bad power supply or insufficient power.

Did you forget to plug in your ghost PCI-E chip. The small board that goes to your other PCI-E slot if your motherboard is SLI ready. You need this chip as a placeholder, for some reason or another..I don't really know why, but something tells me that might be your problem.

Thanks for your reply daviangel!

The Strider PSU got top rating on Tom's Hardware in their tests. They used to be trustworthy before, not sure about now though.

Then it would behave in the same way without the GPU, and it does not.

So I do not need to use it? The motherboard manual said that the connector was for the GPU. There was another similiar one one the side and it was stated to be used for the CPU. If I removed that one, the CPU fan would not move when powering the rig. I assumed it worked the same way for the GPU.

That is just odd because Nvidia says 450W. Oh well. Guess I will return the Strider and try to get hold of something similiar to one of those Silencer Quad's. They are not being sold in Sweden as far as I can tell.

I honestly have no clue what a ghost chip is, but I will keep your suggestion in mind when I get back to the case later.
