Looking for a solid power supply for a good price. I've been looking at these closely:

Estasis 750W
FSP FX760-E
Silverstone ST75ZF
PCP&C S75QB
XCLIO Greatpower 750W

The 750W isn't exactly overkill, it will get its use, but I'm trying to get one that holds up after years of hard use. Whatcha think?

Well... I have the PCPC 750 silencer and have had it for a about a month. No complaints so far. It's a reputable company and owned by OCZ now. Maximum pc always uses them for their dream machine.

Lets see:

By what I could find, I'd go with either the Estasis, Siverstone, or the PCP&C. They have plenty of upgrade options and boast the most amps on the 12V rails (really important if your going to have lots of GPU's to deal with). You can decide which one fits your budget and needs.

Nice research!!!

Definitely looking for the cheapest one and things like modular cabling would be nice for cable management. My previous build I had a FSP Blue Storm which was solid. The Estasis has caught my eye though, and I've heard its server grade. I wasn't sure about Etasis because I've never heard of them, but I've heard they have some awesome PSUs.

This is a good deal;

Take a look at the Corsair 750w http://www.newegg.com/Product/Prod [...] 6817139006

$145 AR

This is a better deal if you ask me. $100 after $20 MIR and has 52A on the 12V rail and has a 5 yr warranty. Not sure if this fits the bill, but is very solid and quite cheap.

Get the PC Power and cooling, it has all 60A on the single rail, and unlike the other options has 2 PCIE 6 pin and 2 PCIE 2 6+2 pin connections. Lastly the crossfire edition is the same thing as the black one, and is generally cheaper, and it looks very nice, black gets old. Lastly the PC Power and Cooling Silencer 750w was the PSU used by Nvidia to show off the 8800 Ultra, that says it all.

PC Power and Cooling all the way.

Shame they're not as good a buy as they are in the UK, where prices for PC P and C are fantastic.

Alternatively the Corsair 750W or the Silverstone.
