I just picked up my new BFG 8800gt OC and put it in my system...when windows boots up its telling the the card has be throttled back due to a lack of power....whats the deal... I am running an Antec Truepower 850watt powersupply...so I know it would be getting enough...I have 2 dvdr's, one HD and a E6750...thats everything in my system....what could the problem be?

More about : 8800gt power

Have you plugged the PCIe power connector cable into the card?
February 8, 2008 5:07:49 PM

Yup...I double checked it too...is there anywhere I can go to check what the card is currently running at?

Well I just triple checked to see if I had power to the card..and it was plugged in correctly...I dont know what the deal it..I tried taking it out and re-seating it ..... I flashed the card with the current firmware thats avaiable for it according to BFG....I was actually getting better preformance from my X1150 that this is replacing...which is actually sad....

Try a different PCI-E power cable... your PSU should have more than one I hope.

There is a fix out for some 8800gt cards that have trouble booting properly with some makes of PS. It is a timing problem. Go to Evga's website and read about it. They have a fix for their cards, don't know if BFG has or not. The Antec is one of the PS that has a boot problem with some cards.

You should contact Antec or vid card manufacturer. I know I've heard this problem before but I can't remember to give you a definitive answer.

return it?

Ebay it and get something else?

Well...returning it is out of the question ...bout it at CompUSA and all sales are final as they are going out of business...IF I did Ebay it how much would be a fair price to ask....

Well, since it's pretty new, I'd say start around $220.

Is there any patch/update in the works from BFG or Nvidia to remedy this problem?

embowe you have tryed both pci-e ps connectors as jay2tall said!you have a warrenty through antec for at least a year,maybe even 2 year? could try one more thing before you rma to antec,and that is your video card came with power connector y cable 2 12 volt molex to 1 6 pin pci-e connector.you have nothing to lose I know it a long shot.

oh yha if you try this use 2 seperate rails.not same cable with two same molex.2 separete cables!

OK..Ill give that a try...I called antec and they said that its a known issue with the power supply...and didnt offer any help beyond that...kinda seemed like they blew me off really....

I use to have this problem when my pc goes back from sleep mode. Its gone now...

1) i updated my bios
2) downloaded the latest driver
3) run ntune on my pc

here my setup:
1) CPU: q6600
2) MD: Asus Maximus Formula
3) Mem: 4 Gbyte
4) PS: Antec Quatro 850W
5) GPU: BFG 8800GT OC 512

This is not a PS problem, at least in my case. There is nothing wrong with PS and it had more than enough capacity for my load.

If I cant get it working by tomorrow..Im just going to return it for a 3870...I dont do that much gaming so I dont think I will have to worry about it...My local Microcenter has the Diamond 3870 for $199...atleast I would be saving 100 bucks..
February 9, 2008 1:03:18 AM

I called BFG and Antec about this issue. They have nothing much to offer. I'm just happy it went away after i downloaded updates for my Hardware.

By the way my PC OS is Vista-64.
February 9, 2008 1:14:53 AM

I have the most recent updates on the card and my bios...and I have run nTune...still no avail
February 9, 2008 1:35:29 PM

Well...after a night of reading and trying everything that I can think of I am going to have to return the card and buy somthing else..Im thinking of a 3870...It sucks that I have to go this route but nothing else I can do
