I posted about a month ago that i had purchased an xfx 8800gts 320m pcie card to put in my a8n32 fx-60 with a corsair 520hx system and i was recieving the loud whirring noise that is a sign the card is not recieving enough power...well i went through the xfx tech people and they decided that the card was probably bad since my system should handle it just fine and sent me a brand new pre-tested card that i recieved yesterday. Well i'm getting the exact same problem... i really want this card to work since i paid for it over 2 months ago and still havent even seen it post.

My exact system specs are

Case: Lian Li PC60b
MB: Asus A8n32-sli Deluxe
Memory: ADATA 3200 (or something, its good 400ddr memory)
PSU: Corsair 520HX (seasonic 3 12v rails with 30amps)
Cooler: Vigor Gaming Moonsoon II (tec cooler, tried the system with it in and out)
HDs: 1 maxtor sata and 1 samsung ide
USB: Logitec g15 and a logitech mx1000 laser mouse
Monitor: Blackwill 19" 1600x1200
CPU: Fx-60 (standard clock, used to be 3.2 but i want this card to work)

The graphics card i've been using is a Gainward 6600gt that works fine, when i plug in the 8800gts and the 6pin pcie plug into it, the system does not post and the loud whirring noise occurs from the card, after a couple of seconds my motherboard does the 1 long 3 short beeps telling me the video card is bad...but this is a pre-tested good card so it's gotta be something else. Any suggestions!?!? I've tried reseating the card and tried both pcie plugs, both pcie slots and even unplugged everything but the card trying to atleast get the system to POST.

Sounds like PSU dood.

If u can, plug the card into a sys with PLENTY of pwr, 600w plus, pref a new sys that u know works with a card like that.

Sometimes a psu can work fine exept for one or two sets of plugs. Ran into that prob YEARS ago, thought my hdd died, spent hours fking around. Once i figured it out, i used a different hdd pwr cable, and the psu continued working fine until i retired the sys a few years later.

take out any add in sound cards or modems and disconnect the power from all your drives and see if it will post. if it does you know for sure it the ps although even if it doesn't post it still could be and probably is your ps but worth a shot anyway. good luck and let us know how it goes.

i've removed everything that i can possibly remove, just the Motherboard and the graphics card in and still nothing It could be the psu i guess but its from a reputable company and it supposively meets the requirements...i just would hate to waste a couple of hundred for something that doesnt fix it

that psu is barely the need to push a 8800GTS...
go buy a new psu seriously.. if some guy is lucky to run one in your psu doesn't exactly mean yours will.

I agree with the rest a new psu is in order but there is one test that may help for now.
Make sure that the 8800 is on the highest 12v rail all alone and use the other rails for the other bits that need it. If it still fails get a new psu....

good luck

Agreed, change out the PSU, I didn't see anywhere in the post where you mentioned how old, and used, the current PSU is. Over time the performance on PSU degrades, honestly, give it a shot, it is easier than changing out the MoBo, and perhaps less costly?

How come any harware problem is always answered, duuuudddee you need a new power supply. What a heap of garbage.

Total system draw, 340 watts. Add a few for that tec cooler and your still under 450. Try to come up with an original solution and not some regurgitated cr@p.

Mac; uninstal old drivers, use driver cleaner, get new drivers from nvidia. If that doesnt work id be looking at my motherboard drivers, then the bios settings. In my limited experience those sli boards give more grief than a single slot board.

the psu is less then a month old as is the MB i bought them both 2 weeks after i bought the card because i was told it was my old PSU and MB and to buy the one's i got for it to work....so it's gotta be something else i just can't figure it out and neither can the xfx ppl unless the new 'pre-tested' card is bad too

Nice quote newb. 8O

I did the calculations here and came up with a draw of 481W

So next time your backwards math is done keep it to yourself.

Also, depending on the quality of the PSU it may not really be able to supply the power it is rated at. In this case the OP has a quality PSU, see the link below, but if he had something like an APEX I would say he isn't getting anywhere near the power it is stating it can put out. So in the end, you can't always take things at face value when it comes to PSUs

http://www.xtremesystems.org/forum [...] p?t=108088

Beyond this, depending on the age of the PSU it could be worn down, bottom line, an overall performance degradation of 20% over two years running at moderate loads is not uncommon. So given any PSU at 550W, -20% for aging, and the final output is 440W, but the draw requirements above it would not work, so without knowing the age of the PSU, or the load conditions over time, it is really hard to say for sure!

To be honest, how can any one of us know without physically testing the PSU, one of the rails could be bad, or some of the parts are running less then ideal inside the PSU, ever heard of DOA.

In the end PSU problems are hard to detect from an operational perspective. If the OP has the tools and understanding to go ahead and test each rail then I suggest he do so before buying a new PSU.

Honestly, to come in with your post and rather ignorant comment really wasn't needed. I agree it isn't a bad idea to try reloading the drivers, it is a cheap solution to the problem if it works, but really, keep your extra comments to yourself.

Nicely done calculation. The calculator said so so it must be true. Bet you did real well in math class too. "Its not wrong, the calculator gave me the solution."

The calculator in that link is anything but transparent. All calculations are hidden as well as the amperage draws used in those calculations.

The review gives the total power drawn by an x6800 combined with either a 8800gts or 8800gtx. To me taking a reading from the power supply is a hell of a lot more reliable than what you did.

Case in point. My 420 watt power supply is 2 years old. It has been running my x2 3800 clocked to 2.6 and my more recently purchased 8800gts for a while now. There goes your bull$hit 481 watt theory.

P.S. Oh and nice opener. I'll say it again, come up with something original.

may be fun to bicker back and forth and such, but my PS is brand new, i've tested the pcie plugs with a multimeter and am getting 12vs on all 3 rails. I don't know what else i can do to test the PSU to make sure it's working properly besides checking the plugs. I have a fluke 787 and am an industrial electrician by trade, but all i know is high voltage AC, never played with dc stuff. If anyone could tell me what i'd need to test it please do.

Perhaps you should connect a 2 Gigawat PSU?!? LOL
People exagerate.

Did you plug in the MOLEX PLUG on the MOBO? It's there to give more power to the graphic card. I think it's calloed an EZPLUG.

*edit

Also try to connect your olg GPU and downclock your FX60 (it uses a lot of power) to something like 1 GHz with 1.1v (or even lower) then you should have enough power... but I dont think this will resolve the problem.

yah i have the ezplug in, and the computer works fine with my old gfx card in, even overclocked. It's what i'm using right now as a matter of fact. I closely examined the 8800 vs my 6600 and it looks like the little tabs on the front stick down further then my 6600, yah know the tabs on the other side of where you screw it into the case. I'm debating on ripping my board out and seeing if i can get it work not in a case, maybe its bottoming out or something when i try to push it all the way in. Anyone have any experience with this?

Try an connect a different cabe to the EZ PLUG. The PSU rails can be split between the cables.

As mentioned by NaDa, you have plugged THREE power cables int motherboard :?: Did you measure the 12V value at all plugs that are in use :?: Have you tried the 8800 in both slots :?: Could you test the card in a friends system, or ask a local computer store to test the card :!:
