Handles all my needs. Being modular makes this even better!

Powers my system without any problems. Runs quiet with eco mode on. Cables are a bit thick, wasn't an issue with my setup, but could be a problem for tight fitting case designs.

This seems like a solid PSU for low power builds. It's affordable, fully modular, and is also a Tier 3 power supply. I don't see how you could go wrong.

So far so good, fully modular which helps in a tiny build like this. it also has an 'eco' mode which shuts the fan off when not needed - i did leave this on in this build though to help pull the hot air out.

* EDIT * I did try the Eco mode - off, it is amazing how much the exhaust helps this build, when the PSU fan was shut off idle temps were up around 45 degrees C

Black cables are awesome. Fully-modular EVGA PSUs for $30-40 are awesome too. 10/10 would reccomend

This PSU is amazing. The cables look nice and, not having a PSU shroud in the case, we needed a fully-modular or semi-modular PSU for cheap that got the job done. It is labeled well, too.

It's a PSU. Modular and I've yet to fear it exploding.

good cheap powersuply, as long as you arent using this with really power hungry parts like vega, 1080s, or some of the hedt cpus then this thing will be more than capable of handling your parts while staying rather quiet. also it is compatible with cablemods' custom cable kits. didnt use in this build but maybe i will pick some up later
