## Customer Reviews

### ⭐⭐⭐⭐⭐ Budget freindly
*by M***. on March 6, 2025*

Super quiet and low heat output. I installed this in a gaming pc 5 years ago and love it. Zero issues

### ⭐⭐⭐⭐⭐ great PSU with a solid rep for quality
*by S***O on April 18, 2022*

This PSU was slightly longer (as indicated) than any of the ones I've had before, and it was a bit of a tight fit in my Corsair 4000D mid-size case. It worked out fine, but I had to plug in all the modular cables before inserting the PSU itself due to the tight fit to get things in there nicely meaning I'd have to take it out if I needed to plug in any additional cables in the future.

### ⭐⭐⭐⭐⭐ Perfect to description hasn’t done me wrong and I don’t see it doing as such
*by A***R on August 30, 2022*

Installing was as easy as pretty much any other psu but since the cables were detachable it was very easy to route all the wires in their place and plan to have it looking nice holding my 3070ti up well and it’s definitely worth the money
