So I bought this PSU because it was on sale and they offer lifetime warranty, although it isn't 80+ certified, in their web page says it has up to 80% power efficency. I was wondering why this PSU is not certified.
Here's a link to the product itself: http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=3276573
By the way, it is performing very well on my 2 week old computer and it is already registered for the "lifetime warranty". So far, so good.
Forgot to mention it has 4.7 out of 5 stars in 729 reviews.
