Computer Build - Need advice

post #1 of 13
Thread Starter 
Motherboard:
EVGA 32-BL-E758-A1 LGA 1366 X58 - $300.00
Case:
Antec P182 Rolled Steel ATX Mid Tower Case - $110.00
RAM:
CORSAIR XMS3 3 x 1GB 240-Pin DDR3 1333 - $107.00
Processor:
Intel Core Core i7 920 2.66GHz - $300.00
Hard Drive:
Western Digital Caviar SE 250GB - FREE
Sound Card:
SoundBlaster Audigy SE - FREE
Video Card:
GeForce 9800GX2 1GB 512-bit - $235.00
Power Supply:
Corsair 650 Watt Powersupply - $70.00

Grand Total: $1,122.00

My question is would the 650watt PSU be enough? I used a PSU Calc from extremetech, but it suggested 475watts. The 9800GX2 requires at least 600watts. I read some reviews for it, and 1 of the 30 or so talked about the GX2 and he said it worked, but I just wanted to be sure before I purchased this. (I plan on sticking with the 9800GX2, so please don't suggest other parts for me.)

Thanks again

Personally I would go with a bigger PSU, if you ever decide to run dual 9800GX2's down the road or change cards and use SLI or crossfire you will be set for it. I own a Corsair HX1000 and a PC Power & Cooling 750 Quad and have used both to power my rig with no problems, very good quality PSU's. It's worth it to spend extra for a good unit.

I agree with becks...You can never have too much power, especially with the 9800gx2, which is an awesome card. A buddy of mine has one, and they are power hungry, but insanely quick. You really can't beat the bang for the buck on those cards

go for a corsair 750W or 1000W
1000 will cover all future upgrades, like going quad sli with the 9800gx2. plus, corsair is a reliable psu brand
nice build, and put some pics when u start building

look carefully at the PSU connectors.
the Corsair and the PC Power & Cooling PSU's have 4x 6pin PCIe connectors.
I dont would get any PSU's with less then that.

I agree with all of them. Personally I'm a little biased because i love my Corsair. The HX-1000 that I have is amazing.
post #10 of 13
personally I believe the man needs to have at least 900 watts when you are pushing multiple GPUs.. I think that you should buy a psu only one time and use it for your next upgrade. yes.. you could get by on 750watts but that all. And if you build a bigger rig later your gonna need something bigger. Spend the money once.
