I saw some reviews about the two PSUs and i realized that
XFX PRO 550WT which give at max load total 602W
On the other hand , SeaSonic Bronze 520W which give at max load 113% total 588W
and what i care about is the price which is little difference in my country and i`m live in EGYPT , there`s about 50 LE in price between them
and my question is can i buy Seasonic Bronze 520W or should i go with XFX pro 550W to be safe with my 660GTX ??
