I believe that Zebronic is known for exceptionally low-quality units. I don't see it on any of my current listings, but there's an old one that ranked PSUs in tiers, and Zebronics was on the "Do Not Buy" tier 5; the worst of the worst. If your old one was killing hard drives, it may have been damaging your motherboard too.
Regardless of what else might be damaged, you need to get a quality PSU for your system. If a Zebronic "450w" PSU-shaped object could run it at all, a 380W Antec Earthwatts would have no trouble at all with it.
Lawl that wat i got confused... i wanted to start my pc asap.. so just went to the shop got one.. Well i'll just order a new one today..

i read Zebronic and instantly thought about that old simpsons where that shady tv salesman was trying to sell Homer a genuine "Panafonic" TV. Dude, your old psu was killing your machine, would have thought that would have encouraged you to get a better one. Something from the seasonic, antec, corsair or xfx should do the job just nicely.
