That PSU is on the list of do not buy and that was a good guess about India. Here is the list of PSU's from tier 1 = best and tier 5 = worst. The Zeb (Zebtronics) is on tier 5.
So I don't know if you should trust a new PSU if it is also a Zeb. You should look to find how many amps are on the 12v rail or rails. When I was trying to look up the spec's on the Zeb.
It did not show anything, there wasn't any sticker on it. I guess it will be a hit and miss thing. I guess I would go with a 500w of the same as Zeb but if you could look for the Corsair, Antec, Seasonic, and XFX brands. Those are what I would go with. I do wish you good luck.http://www.eggxpert.com/forums/thread/323050.aspx
