Default Power Supplies

I am building a new computer and have all my parts picked out except for the power supply. My problem is that I dont know what is good to look for in this particular part of a computer. Are certain companies better than others? Is most of the performance based on the amount of watts the PS is?

These are a few that I was looking at, they are all roughly the same price I just need help w/ finding out which one is best.

Newegg.com - CORSAIR CMPSU-650TX 650W ATX12V / EPS12V Power Supply 100 - 240 V UL, CE, CB, TUV, FCC, CCC - Power Supplies

Newegg.com - RAIDMAX QUANTUM RX-700 700W ATX12V V2.2 / EPS12V SLI Power Supply 100 - 240 V UL, CUL, FCC, TUV, CE, C-tick, CCC, CB - Power Supplies

Newegg.com - APEVIA WARLOCK POWER ATX-WA750W 750W ATX12V / EPS12V Power Supply 115/ 230 V CB, CE, TUV, cUL, FCC - Power Supplies

Newegg.com - OCZ GameXStream OCZ700GXSSLI 700W ATX12V Power Supply 100 - 240 V - Power Supplies

The corsair is the best but list your system so we can best decide which will best suit your needs. You do understand that it is amperage on the rails is more important than the total wattage it's rated at right?

Wattage is not important, amperage is more important.

I like to note that it still IS important but just not nearly as important

It's important because the amperage makes up the wattage.

You can get away with alot less.

There are many many choices, but, the Corsair 650TX will be fine.

You can start by eliminating the Apevia and the Raidmax since both are avoid brands....

Now its OCZ GameXStream vx the Corsair 650tx... the 650tx in terms of its rails (and wattage isn't as important as rails)

If you want a good explanation of rails check out a 3dgameman review

The Apevia Warlock is actually good.

Hi-Tech Reviews | Apevia Warlock 900-watt Power Supply | Power, Supply, Var, Apevia, Have
Apevia Warlock Power 750 Watt Power Supply Reviews - OCIA.net


But corsair and OCZ are more proven, so even though the Warlock is good, I would go with the corsair.
