First of all let me apologise for posting yet another 8800GTX topic, I've trawled throug quite qnumber of the others and I'm still not convinced, hopefully you can steer me in the right direction.

I recently gave my system a thorough overhaul (replaced everything except the PSU) the PSU had recently been replaced by myself as the previous PSU was just too noisy.

My PSU is a Coolermaster iGreen 600W, it has 3 12v rails putting out 19.5A each, I had done a little research and had figured this to be enough to supply an 8800 GTX.

After building my system today I'm experiencing some problems, when starting the system it hangs on the CPU ID or memory count.

It gets stranger, it only gets that far with 1 stick of 1GB ram in, adding the second causes the system to give no display, however if I unplug my USB keyboard and mouse I can get the system to boot, plugged them back in when I hit the desktop, ran 3DMark a few times, seems ok.

I still have to unplug my USB's though to get it to boot.

Is the iGreen 600W up to the task or should I start looking at something else being the cause?

Appreciate any info you could give me on this.

You have to list the rest of your system specs for us to determine whether it is a psu issue or not.

I could be way off with my PSU choice, peak output it seems to state is 25A.

It also states on the site I bought it from...

12v Rail AMPs: 20 A (whether or not it means total or each rail I'm not sure).

Apologies, system specs incoming.....

AMD AM2 4600 (energy efficient) cpu
Abit KN9 Ultra AM2 board.
Creative Audigy 2 ZS
2x1GB Corsair XMS 6400 memory modules
1x 320GB SATA connected at present.
No Opticals at present.
Pallit 8800GTX
and of course the afforementioned iGreen 600W PSU.

USB periphs are MX1000 mouse (self powered) and a Logitech G15 keyboard.


No chassis fans connected either so no excess power loss there either.

The PSU should be more than enough for the rest of the system, it powered my last system which had 4 PATA drives, 6 SATA two opticals, but a radeon 9800pro 256.

Just not so sure if it's up to supporting an 8800GTX, everyone seems to be saying I should have a PSU with 4x 12v rails instead of three.

Serves you right for buying a nice card... :wink:

Send an email to NVidia and see what they say. I've asked them questions before, and their customer service is quite a bit better than most (in my opinion).

Meh... flash your bios? Sounds more like a mobo issue than a PSU issue... Do you have anything to monitor your rails?

That 600W should be able to supply your system fine, not to mention USB barely takes any power...

Thanks for the info guys, Nvidia are a pain to talk to via email or otherwise unless you bought directly from them, so I'll skip them altogether.

I'll take Doughbuy's advice and flash my mobo, was a little concerned about only having 3 12v rails.

I'll look into monitoring, see if I have any way of doing so.

If flashing the mobo doesn't help, it still could be the psu. Just because the psu seems big enough doesn't mean that it is. It may be faulty, for instance, and not putting out its rated power. The differing amp ratings that you found also makes me wonder about it. The higher ratings that you listed seem fine, but the lower rating may not be quite enough. Don't know for sure, but something to think about.

Just my 2 cents worth.
