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.

Does what it should, and quiet too.

Always trusted EVGA, great power supply as always

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.

Good small sized (150cm) atx unit with plenty of power and fully modular cabling. No issues buying again.
