Overkill. My HX750 ran a power-hungry Thuban and a pair of 5850s all summer. For a Sempron system, 750W is a a waste of money.

I'd agree with this. For a 2x 5850 setup, the 650 is a good setup. The only difference for the OP are the connectors really, but the power is all there for the 650W.

That said, my vote is for the TPN. 4x PCI-E connectors and great power at the same price.

On a side note, PSUs are becoming extremely underrated these days. I've fond memories of a GTX 260 216SP/9800GT, both OC'ed with an OCed Q9550 setup on my Corsair VX550W. F@H with no issues with both cards.

Given the fact that the electrical quality on the Antec TPN-650W is much higher and it's based on a more modern design, the chances of it dying are lower. That, and the warranty is 5 years. Antec's warranty is excellent, too. And since this is gonna be used in a rig that will likely be powered on 24/7, power consumption matters. The TPN also has higher efficiency.

Sorry, no reason to go Corsair. The TruePower New 650W is better on everything.

I'm pretty sure my sig rig PSU could run another 5850; on my other motherboard though, as this one does not crossfire.

I would disagree here -- I've had to use it, twice -- and I'll have to say neither experience was good.

Why people keep recommending the Corsairs at this price point is beyond me.

From what you're talking about, to me it seems that the Tri-GPU config you're talking about would be for folding. Am I correct? If that's so, don't worry. I wouldn't game with three of them, though. The power consumption would probably be in the 600+W range. For folding, you're fine.

I'm still wondering why you're using AMD cards for folding, though.
Cool, thanks. Not folding, bitcoining.

Both of those PSU's are currently the same price BTW, but if the Antec is better, I'll go with that.

And since I have you all here... what kind of a PSU would be necessary to run FOUR 5850's? I'm assuming around 800w minimum?

An Antec TruePower New 750W or a Corsair TX-750 are just fine for four of them.

But, like I said: if you're gonna run three, there's no reason to get the Corsair. It has worse ripple, is less efficient, is based on an older design, has all the cables hardwired, and doesn't have 4x PCI-E 6+2 pin connectors.

Mine was great the 8pin was dead and I even opened the psu and the screw had a sticker with a "void" thing and they still replaced it. Took a bit longer then I hoped, that's the only downfall.
