I'm trying to decide between 3 PSU's.I've already figured out what size I'll need, but I'm having a hard time deciding.These are the 3.

Corsair TX750W

Thermaltake Toughpower 850

PC Power & Cooling Silencer 750 Quad

Thanks for any help

All three are good units. Pick the cheapest one. Based on regulation at full capacity, I'd rate them as:-

TT 850
PCP 750Q
Ultra X3

But, here I'm splitting hairs. All three are good quality units.

often times you can get the PCP 750w for only $160 shipped on sale on various websites, imo from that list you provided i think it's the best Value/Quality ratio

PCP was the one I was leaning towards because of quality.

I know 750 or 850 might be overkill. what could I run this setup with some head room?

My rig
ASUS MAXIMUS FORMULA

For that rig, in theory, you can get by with a good 550W-600W PSU like the Corsair VX550, HX620, Silencer 600W, Evostream 600W, Toughpower 750W etc. The simultaneous spin-up draw of those HDD's have to be accounted for in all your calculations (say a worst case of 2A on the 12V and 1A on the 5V).

I've been using OCZ 620 for almost 2 years,do you think I can get by with this?

[Super Nade]

Yes, but your ability to overclock may be hampered a bit. The OCZ unit does not like to be cross-loaded. Try it before you spend any money on something else.
