Difference between PCP&C's 1KW PSUs

Well to be totally honest, I'm not 100% sure of the difference, but at the very least, I would imagine it's simply that one PSU is optimized for CF, the other Q-SLI.

As far as I know, CF requires a helluva lot less power than Q-SLI, coz you're running two GPUs instead of four. Again, I'm not entirely sure...that's just my guess :rolleyes:
 
exactly what it sounds like. Crossfire, or quad sli, or the normal version.
 
the difference is just in the power connectors. The quad-sli version has 4 pci-e video card power plugs, while the other versions have 2. Other than that they're identical.

Wrong. The Turbo-Cool 1KW has 2 PCI-E connectors, both the Turbo-Cool 1KW-Quad SLI and the Turbo-Cool 1KW CrossFire have 4 PCI-E connectors.

okay, so the crossfire one has 4 connectors. But I was still right that the difference between the quad-sli and the regular one is the number of power connectors. :rolleyes:
 
The 12 volt rails are arranged differently between the regular 1kw one and the quad one. I'm not sure about the crossfire one.

Um, yeah. Did you read the specs before you posted them? They look different to me...

 
The graphics are on their own rails for the sli and crossfire. The regular one has the drives on the graphics rails. And the sli and crossfire have 4 pcie power connectors the regular one has 2.

OK, I was thinking it was just a labeling difference, since they still have
+12V1 @ 16A
+12V2 @ 16A
+12V3 @ 36A

but if they actually change what rail the hard drive connectors draw from than, yeah I can see a difference.
How can the regular one have 2 rails for the CPUs? Maybe the regular 24pin ATX connector draws from one and the 8pin from another?

The regular 1 KW has the 36 A rail on the 24 pin and everything else, and the two 16 A rails are both on the 4-pin and 8-pin EPS12V. Each of these connectors has both rails, on different pins.

One of the reasons who it wouldn't work for me...

Note that supposedly PCP&C has an entirely new design in the works with a less stupid rail setup for multi-core servers. Hopefully a one-rail design.

Apparently not, and that is with the 7900GX2s, the 7950GX2s are smaller, and possible consume less power
