Hello, i recently bought a ATI HD5770. so i am thiinking of buying a new psu since my current psu is only 350w. now i am short on budget so i chose Cooler Master eXtreme Power Plus 550W psu. is it good enough for HD5770?
Look for a different psu since that one can't provide it's labelled power output.
Is it good enough for a 5770? sure but is it good enough for your system ? i doubt it. http://www.hardwaresecrets.com/article/Cooler-Master-eXtreme-Power-Plus-550-W-Power-Supply-Review/969/1
The OZC suggested in this review is an option i would consider and the ModXtreme line also features modular cables.
I have a 600w model and i'm satisfied with it's performance after 1yr of daily use.
Antec Neo and Corsair VX are others i would consider in your price range as well as Seasonic.
Look for an 80 Plus certified unit. That CM is less than 70% efficient. The OCZ mentioned above and Antec BP550 Plus are great options in the same price range.
The Corsair CMPSU-550VX and Antec EA-650 are solid choices. Antec's Basiq series is their OEM line and to be avoided. I find that going below 650 really doesn't save much money.

Gotta agree with you here. Plus the fact that 600W is about average for a new "budget" performance system. I don't think that less than 800-850W would suffice for a good upgradeable system nowadays. Nice to know about the BP's. I would guess that most top manufacturers have lower end "competitive pricing" units out there.
