6600GT not receiving sufficient power.... help

Leros

Lifer
I just purchased a PNY 6600GT video card. I keep getting the message that it is not receiving sufficient power, however I have the card plugged into my PSU.

I have anAspire 450w PSU. It has a 30A 12+v.

I am powering:
Gigabyte GA-K8NS Pro nForce3 250
Athlon 64 3400+ CPU
2 X 512 Mushkin Ram
120G Seagate HDD
80G Seagate HDD
CD-RW
DVD-ROM
Floppy
4 case fans
zalman CPU Cooler
a cold cathode

I should have plenty of power, but I tried unplugging cd drive, dvd drive, floppy drive, 1 hdd, cold cathodes and turning down the fans as low as they go. It still gave me this message.

what the heck is going on?????



 
um, i may be wrong, its late and i've been drinking..lol...but i thought 6600GT cards dont have the socket to plug your power supply into? they can draw all they like from the pci-e slot?
 
Some have the external power, and some do not.

JToxic, is the plug to the card, straight from the PSU? If not, perhaps try that. Maybe your 12v is low, as can be the case with cheaper PSU's. If its not, 30A should be more than enough to power what you have.

Try unplugging all hardware you dont need to run the PC, and start it up. See if you still get the same message.
 
According to those specs, your PSU should have plenty of power to spare for the stuff you're running. But just because it says it can drive 30A (usually a BS peak number), doesn't mean it can do it and be stable at the same time.

It's always worth spending a good $100 for a quality PSU from a well-respected manufacturer. If you're unlucky, a crappy PSU can end up costing you the rest of your system.
 
Yeah, I thought only the 6800GT had the molex connector, but what do you know, ithe 6600GT does also, will on my Gainward it does.

I know 🙁

Is my Aspire PSU not a well respected quality one?

 
i tried unplugging everything unnecesary and I still got the power problem.

I took an old 350w (12v @ 12A) PSU and plugged it into the card. So that the only thing running off that PSU was the video card. I am still getting the error message.

So I think I can rule out a power problem. What else could be causing this???

I do not know if this is related: yesterday I tried installing a 9800 pro and got some mild artifacting.

I installed my old 9200 radeon and it operated fine.

 
Its probably a bad card if its still doing after you've unplugged everything. 6600gt's don't use a too much power, so your aspire PS should be able to run it fine.
 
I have yet to flash my Motherboard BIOS. So I am still running the same BIOS that it came with when it was in the box.

Would upgrading the BIOS help at all?

 
OK, so it sounds like the card itself is defective.

Seems a little odd to have two defective cards in two days, but I will return this one and try again.

 
I didn't see your post where you said you had getten artifacts with a 9800. That makes me think that it could be an issue with the motherboard, if two cards that require a decent amount of power are having issues while a low power card is fine. Could it be that the AGP slot isn't giving the card the power it should?
 
Another thing.

When I had my 9800 pro it bencmarked 1053 with 3DMark05. And with the 6600GT it benchmarked 167 (yes, 167) with 3DMark05.

Keep in mind I am comletely broke ( I have $10 excess money). I think I should return the 6600GT and get a new motherboard.

BTW, I tested the card in an old computer (around 5 years old, 1000mhz P3, 128mb ram) and it worked fine.
 
if you have tested the card in another system and it worked than you need a new motherboard, or you should really try to update the BIOS, something could be screwy with the AGP voltage
 
I updated the BIOS, didnt help.

I would like to test everything before I go and get another motherboard. I dropped off the PC at a mom & pop computer store to see if they can pinpoint the problem. They are also one of the few places I can get a mobo locally.

We'll see what happens.
 
I got the computer back a few days ago. Turned out that all of my components were working correctly. Just to be safe I went out and bought an Antec NeoPower 480w PSU. The card still didnt work. I returned both the PSU and the card. I ended up getting a 9800 pro 128mb. Not nearly as good, but it was $50 less and it WORKS.

I may have just had two defective cards in a row. Who knows.
