Pros: Solid product. I bought it for the brand name and because at the time it was the best buy for my scenario. I originally was going into my new build looking to use SeaSonic but at the time they didn't have anything that worked for me in my budget range so I took a gamble on this. I haven't had any issues or complaints in the same fashion and to be honest never honestly have at all with a GB product.

Cons: NewEgg cliche of something about how it didn't make me breakfast.

Overall Review: Gigabyte has never let me down and I've been using their motherboards for close to a decade. I don't use this to power anything massive (i5 Haswell Refresh/7770/8GB DDR3 1600/1TB HDD) but I wouldn't hesitate to upgrade and do so if I ever intended to. Very silent fan, reliable, not much else to say.

Solid Caps sold me 7/1/2013 1:26:45 AM

Pros: This unit commented on its use of solid caps. I have seen lots of PSU failures due to electrolytic cap failures. The cables are nicely packaged in sleeves and there are plenty of them. Includes rear switch and is quiet. Gigabyte builds quality in my book and this one is at a very reasonable price.

Cons: None.

Overall Review: The quality of Gigabyte motherboards and the solid caps led me to try their PSU.
