It's made by Enhance by the way, here's a review: http://www.techpowerup.com/reviews/C...VSM750/11.html
For the price of a v650s you're better off with the evga 750 G2 that has a semi-passive fan mode, is fully modular and is overall much better built along with better electrical performance.

No point getting Seasonic these days over a Super Flower unit unless its cheaper, you aren't getting a PSU from Seasonic for the price of the 750 G2 with that build quality/performance/semi-passive fan.
