Help me interpret these 1U Server PSU Specs

[yottabit]

Hi everyone!

I'm looking at this particular 1U PSU as a candidate for a kind of unconventional gaming rig.
http://www.fspgroupusa.com/fsp460701ug80/p/626.html

It lists 3 seperate 12V rails with 16 A each. The outputs are 1x PCIe 8 Pin 3x 4 pin Molex 2x SATA and 1x FDD

The 8 pin would be going to my mobo to support a Core i5 750. I would use 1 SATA for a HDD, and then I would want to use adapters or some manual soldering to produce 2- PCIe 6 pin connectors for a video card. I presume I could pull from the two molex adaptors and the remaining sata adapter...

How do you think the 3 12V rails are split up? This thing isn't going to be powering a monsterous card, a GTX 560 Ti at the most. In the end I think I'm just going to be using it with a 5770 that requires 1 6 Pin, but I'd like to know the option is there for a 2x 6 Pin graphics card.

Thanks!!!

Hmm... reading through the sticky here, it sounds possible that 2 rails are dedicated to the 8 pin PCIe adaptor. That would be unfortunate for my needs, but I wonder if I could splice in a 6 pin adaptor for a video card onto one of those rails?

Actually, image 5 on there shows which rail is going where, but the text is really small.

Looks like:

+12V1 == one half of the EPS12V (It isn't 8pin PCIe), and one half of the 4pin P4 (weird).
+12V2 == the other laf of EPS12V and 4pin P4 plug
+12V3 == 24pin ATX plug and all the molex and SATA plugs.

That is one strange rail distribution in my opinion 😵 :hmm:

Okay, thanks. I think the hefty bias towards the 8 pin is because this is a server PSU and probably intended for dual-chip multi-core CPU's... I never realized the 8 pin connector on motherboards wasn't the same as a PCIe connector, I should've known though 😛

I'm guessing my best split then would be to put one 6 pin off 12v3 and one 6 pin off 12v2
