I noticed that both of the following PC Power & Cooling PSUs are similar but priced a bit different. Is there a particular one I should buy over the other? I am going to use it for a quad core CPU and 8800GTX in SLI.

Turbo Cool 1KW-SR 1000W

vs.

1KW-Quad SLI (TC1KW4E) 1000W

The first one you list is a single-rail PSU and the second is a tri-rail. That's the difference between them. The tri-rail splits your 12v rails into 3 (12v1, 12v2, 12v3) whereas the single 12v rail stacks all your amps together (72A).

Looks to me like the single-rail is better because it has a few more amps. But honestly, no way in hell I would spend near 500$ on a PSU that has less amps than the competition who is just as reliable. Silverstone has a model (ST85ZF) that's around half the price of those and has just as many amps on the 12v rail (72A). It'd be a much better buy unless price just means nothing to you.

I just got one. But I will be getting my evga 680i motherboard monday, I have two BFG 8800GTX, s and a intel 6600, now it look's like SLI is a Problem with sound, Damn I want to use both my 8800 Gtxs:p

Wasn't the first revision quad 12v rails?

I bought the Turbo Cool TURBO-COOl 1KW-SR for my 8800GTX SLI rig. It is so loud I can't stand it. I ordered it from the company and paid $549.00 for it. It is not worth the money to me. I can't stand it. :thumbdwn:

Have you ever used a 510w turbocool? If so are they similar in noise levels?

No, I haven't used any of PCPower's PSU's before. I wouldn't of bought this one except it is recommended by NVIDIA on their website. Mine is miserable loud and for $549.00 they could of done better than this. I spent $349.00 for Enermax's 1000W and it came defective. I had bought it early anticipating the 8800GTX launch. I got stuck with the shipping fees back to Enermax too. I haven't heard anything back from them either yet and I shipped it back last week.

Anyone know how 8800GTX SLI is holding up on a Silverstone Zeus ST85ZF 850W? Sorry for sounding dumb but I do not have any experience with current SLI setups.

PCP&C doesn't make quad rail PSU's. From their website, for that particular model you reference:
DC Output
Output: +5V @ 30A +12V1 @ 16A (CPU) +12V2 @ 16A (Drives) +12V3 @ 36A (Graphics) +12V1,V2,V3 = 66A (70A peak) -12V @ 0.8A +3.3V @ 30A +5VSB @ 3.5A continuous power = 1000W peak power = 1100W

Just fine. That's what I own. It's more than enough power for 8800GTX SLI.

Go with Seasonic whenever you can. They are usually the references for what PCPower uses but are MUCH quieter and MUCH cheaper. The 600W I have is the best PSU I've ever owned.

This man speaks the truth.
