[MarESam]

Okay so i'm planning to build a entry level online gaming and for everyday use PC(i'm not into first person shooting 'cuz i feel dizzy while playing ) and my problem is what PSU to use?

here are the components that i'll be buying in ten days(January 10):

Processor : AMD Trinity A6-5400k ($67)
MoBo : Gigabyte GA-F2A85X-D3H ($99.80)
Video Card : Sapphire HD 6570 1GB GDDR3(too bad A6 can't XFire 6670 ) ($57.20)
Memory : Corsair Vengeance 4x1 DDR3 1600 ($30)
HDD : Western Digital Caviar Blue ($55.99)
Optical Drive: some cheap DVD-RW from my old pc
Case : I have Antec 600SE(not so really bad choice ) ($58.42)

I'll be choosing from three Brands :

TOTAL-
Corsair $409.55

Get the corsair, it's a decent quality psu, 450w is more than enough for your system.
