Ok, i figured this thread would be a good place to ask a question i have. I am looking into a new PSU for my benching rig. Currently i am benching cpu only, as i do not have the $ for high end video cards currently. I am benching on air right now, but i have cpu and nb DICE pots i plan to use once i feel like i have mastered the mobo and maxed the 2 procs i have out on air. The PSU needs to be around $100 - $130. ($130 before MIR's). Here are the one's i have been looking at:

TT 750w modular [60 amps on 12v] - $125 free ship: http://www.newegg.com/Product/Product.aspx?Item=N82E16817153104
Antec 750w partial modular [62 amps on 12v] - $130 free ship: http://www.newegg.com/Product/Product.aspx?Item=N82E16817371025
Silverstone 750w [60 amps on 12v] - $130: http://www.newegg.com/Product/Product.aspx?Item=N82E16817256049
Corsair 750w [60 amps on 12v] - $110 free ship: http://www.newegg.com/Product/Product.aspx?Item=N82E16817139006

A little out of my price range, but very nice:
Corsair 850w [70 amps on 12v] - $140 free ship: http://www.newegg.com/Product/Product.aspx?Item=N82E16817139009
Ignoring the 850w Corsair i posted, what would you choose(TT, Antec, Silverstone, or Corsair)? considering brand, power, and price?

What logic led you to this conclusion?

Well, it is about extreme benching, and this is a decision for my benching rig with DICE. I consider any sub-zero benching extreme.
 
If you want me to, i will just make a new thread in the overclocking forum, and will delete my post here.

just about any serious 550 watt (750 is a nice round number) on up power supply will hold you for the time being..you wont be able to max the power to the cpu on air (600 watts)

General hardware is probably the place.

Of the ones in your range, get the Corsair. I'd make the effort to spring for the TX 850, though. You'll use every bit of it once you start benching multiple cards.

what up nate... im still waiting on things. im still around though.

I agree. This is a good place to ask any sort of questions relating to benching. Especially sub-zero benching. To answer your question, I would go with the TT, or the Corsair as they're the brands that I've heard most about.

Ok cool. I just wanted a few opinions. Two more quick questions. I am a big fan of Corsair units. But the 750tx and 850tx are only 80plus cert. while the other psu's (TT, SS, Antec) are 80plus bronze. How much of a difference does the efficiency actually make? Especially when drawing near peak power (which i know won't happen without a highend gpu or 2 and a heavy oc on the proc).

I know Nate is running a 1200w and 860w pc p&c. If i got a 750w now, would getting a second one and running dual psu's of this wattage be sufficient for very high end benching? Or would one main large psu (1000-1200w) and a smalled secondary (550-650w) be better?

I am just trying to plan out my power usage for when i start benching all very high end stuff. Remember, i will be going under DICE very soon, and ln2 eventually...

your going to need to spend quite a bit more than your willing...

you can start with a corsair hx1000 1k. it seems to max out at about 1130 watts or so before the unit just shuts off.
that will run your whole setup including you over clocking your cards and running on dice.

So John, you are saying a bigger psu and smaller would be better than two average sized ones? So a 1000w+500w would be a better option than 2 750w ones? Or are you saying i should have a big and average one? So 1000w+750w?
