I want this power supply:
http://www.ebuyer.com/191850-powercool-750w-modular-psu-80-dual-12v-v2-2-high-efficiency-psupc750aubam

but evidently it comes in 450w,550w, 650w and 750w,
the system i want it to be powering is...

AMD phenom II 965
gigabyte GA-990FXA-UD3
GTX 550 Ti SLI x2
optical drive and wd 500gb/standard

I'm wondering what is the minimum wattage power supply i could get away with using without suffering from not enough power?
I have never chosen a PSU before so i'm checking with you guys!

Thanks.
 
Why would you do such a low-end SLI?
Also, if you really want that setup, then a good 600W PSU is my recommendation.

Great PSU brands: Seasonix, XFX, Antec, Corsair, and PCP&P. Rosewill and a few others are decent and almost anything else is junk. JKatwyopc's recommendation is a good recommendation.
 
Why do you want to have GTX 550 Ti SLI? A much better single-card solution can be had for less money than two GTX 550 Ti cards and even if you already have one or both, it would be better to sell them now and replace them. They're somewhat overpriced at the moment, so you can probably upgrade without actually spending money.
