Hi guys.
I've newly built a computer for my first time but I'm experiencing a problem.
When I switch on my PSU, A blue light lights up on my motherboard and the "power" on my front display lights up. But none of the fans or other components starts. CPU, Graphics card, psu fan... nothing is responding.
Any suggestions on what I should do? I think I've plugged in all the wires to the right places etc.System spesifics:
Motherboard: XFX nFORCE 680iLTsli
CPU: Intel core 2 duo quad Q6600 2.4Ghz
GPU: XFX gFORCE 8800GTS 512MB
PSU: Chill innovation 520W
RAM: Crucial DDR2 BallistiX PC6400 2048MB
HD: Seagate Barracuda 7200.11 500GB
simply put your power supply is not enough for what your running. the 8600gts alone calls for a 400watt min power supply. upgrade to 700watt minimum. hopefully that will help your problem.
you gotta include your hard drives and cd roms along with fans and spiffy lighting effects that most people have now days.

When building a PC, it is always best to benchtest the components before final assembly. That way you can spot any problem without having to tear everything apart, which is what you are going to need to do here.
Secondly, why did you go for an nVidia chipset over an Intel chipset to complement the Q6600, it's not like you'd ever be able to run SLi with that inadequate PSU anyway.

Hmmm, don't know where you got the 400watt figure from, last time I looked the 8800GTS 512MB alone required less that 150watts. Wattage isn't the only factor that affects the performance of a PSU.

Well, I was told that 520W would be enough for the 8800Gts, But I might borrow a More powerfull one from a mate in some days.
But if i disconnect the power cable from the gpu, I'm getting the same result as before. The power light in display lights up without me even pushing the power button, and none of the fans etc are responding.
I've tested it out with 2 PSU's aswell one 400W and the 520 I intended to use, getting the same result both times.

Sabertooth:
I was thinking of upgrading the gpu to Dual gpu's with SLI later on.
As I said this is my first time building a computer, and I don't even know what bench testing is! Care to explain?

hmm the 8600gts figure come from the Evga site and cuz i have two evga 8600gts in sli
now, now, lets not try to bash others attemps to help some one. just remember the 700watt psu will give him more room for future hardware and extra.

you have both power supply plugs in right there should be a 20pin connector and a 4 pin connector. check and see if that is the problem.

You shouldn't base a PSU selection soley on wattage. Here's a clip from a review of the Chill Innovation 520W:
"The 520w is a stable and stylish power supply featuring cable braiding and an 80% plus efficiency rating. However, it isn't a particularly powerful PSU so if you are going for a high end SLI or Crossfire rig we would suggest a more powerful model. Also, those looking to invest in 8pin powered GPUs in the future may find this PSU a little limiting"http://www.xsreviews.co.uk/reviews/...
I doubt the PSU is to blame, but it is a possibility. As Sabertooth pointed out, the system should have been benchtested to confirm the components worked BEFORE it was installed in the case.
I suggest you gut the case & start from scratch.

Sorry, I missed that sentence. Benchtesting is just what it sounds like...testing the hardware on a bench. What you'd need to do is place the motherboard on a non-conductive surface with just the following items connected:
- CPU w/HSF
- one stick RAM
- video card w/monitor
- keyboard
- PSUThat's it...nothing else. To power it up, make sure the PSU & monitor are plugged in & switched on, then momentarily touch a screwdriver blade across the 2 pins the power switch would normally connect to. If your components are good, you will get the POST screen. Use the keyboard to access the BIOS & adjust the settings as necessary...check the CPU temp while you're there.
If the system doesn't boot, you'll have somehow determine which component is the bad one.

I guess I don't have to cover the benchtest inquiry anymore than jam's already did.
Now aside from your PSU being inadequate for an SLi system, such a project is never cost efficient in nearly every case. This is because there is usually a card that cost less than both of your SLi cards & also perform better than the two cards.

Thank you very much for the suggestions.
When I get home tomorrow I will bench test it with the current PSU and a 900W PSU I borrowed from a friend.

I've figured out what the problem was!
Actually, the "start" buton on my front display was defect!
I found this out by trying to start the pc with a screwdriver when benchtesting it.The 520W PSU are actually giving enough power to my 8800GTS GPU and everything..
