It's a Seasonic.

I have not had any issues with the PSU yet and have really appreciated the product as a whole. I have had terrible luck with PSU's over the past couple years with Sparkle and then a Corsair blowing up and thrashing my rig. This Seasonic has weathered the storm and seems to be no worse for wear yet.

I would recommend this to anyone in the market for a PSU in this size happily.

There isn't really anything bad to say about it. The price is somewhat higher then others but this type of quality should be sold at a higher price. I wish it was bigger sometimes but that would just make me buy more GPUs so its not a bad thing
