Sleek looking and excellent PSU. Fully modular which makes cable management easier. Size was perfect for my build. It has ECO mode, yet even with the fan running, it is incredibly quiet in my opinion.

Very good power supply for the price that I got it for (119) that I bought because I needed an upgrade to power my 1080 from my 500w 80+ EVGA power supply that was powering my system when I had a 1060 inside.

overkill for this build? YES but I was able to get it for $10 more than the Supernova 550 G3 (after rebate) so it was a no-brainer to get the extra headroom and the extra 3 years on the warranty

Nice build quality. The eco mode keeps the fans running only when they need to, which keeps the case quiet under low load which is nice.

Rock-solid, powerful, and surprisingly compact. I really recommend EVGA G3 series PSUs for their stability and the fact they fit in just about any case very well. Only complaint is the placement of the heatshrink and components in the cables can make them difficult to route sometimes or have a giant heat-shrink bulge on your motherboard cable. I recommend buying a cable kit for this.
