Is this power supply good enough for this config?

Hello, I was looking around for a computer and found this. But I wonder if the power supply is good enough?

Well, I've done some searching and I can't find ANY Information about the 12v rails of that power supply, which describes how much power the power supply can deliver at that voltage, and 12v describes the CPU, GPU, and the mobo; the three biggest energy consumers in your computer.

500w, IF the 12v rail(s) are designed optimally, will have no problem powering that system.

Ah, ok. I'll ask about that. Thanks!

The psu appears to have 3 separate 12V supplies @16A (Zoom in):

Don't know if it has the 2x6pin connectors, though.

Odd that you can't easily find this data when its a barebones PC lol.

Update: The manual for it shows a crossfire installation example.

Nice find Twoboxer!! But really? 3 * 12 * 16 = 572 watts... for a 500w PSU? Anyway...

Let's see... so if we can isolate each GTX 260 onto each rail we can technically leave an entire rail for the i7.

It should work, if you can balance the rails properly =).
