Hi guys,

I am using Zebronics 450w gold psu and i recently bought Sapphire hd5770, i am facing strange problem some time when i start my PC, it doesn't post (exact situation is everything switches on i mean all fans leds, HD5770 fan Green led's on backside of it switches on) but no display with beep sound. so i press reset button to get display and surprising suddenly display posts. I am confused whats wrong with Mobo or HD5770 or psu.

Pls help...

Thanks in advance for your replies .... ;)

+1^ or Seasonic OCZ. If you buy one of the following brands you only need a 400w psu. a Zebronics will not produce its rated 450w.

ok guys taking your opinions into account, and after deep thought process about my ZEb gold 450W PSU, I replaced it with brand new SILVERSTONE ST50F-ES 500W PSU @ $63( efficiency 85%+). now pls review this one and let know if my choice is good or bad. Feel free to comment if u have any bad reviews about it as well...evryone is welcomed... ;)
