## Description

Buy

Review: Very quiet fan, high quality PSU with plenty of connectors - I was worried about how much noise this fan would make, so went for a PSU with a bit more power than required. If the PSU is not being used to full capacity, then it will reduce the fan speed by a bit. A little pricey compared to other fans but better value than the going market rate in comparable shops. You get what you pay for in PC fans and this is made to a very high quality. The first time, I have ever installed a PSU that fitted in first time, without having to add or modify any of the power connectors. This PSU has all all the power connectors that you will ever need for old and new PCs.
Review: Does what it says on the tin: very quiet PSU. - I bought the 500W version of this PSU to replace a Corsair CX550M which was perfectly fine but was definitely the loudest component in my system. I was expecting the sound level to drop when I installed this, but the difference was truly remarkable. It is virtually silent now when under low load, which is the most critical time when I want the least noise (when watching videos or working quietly). I have a Noctua U12 air cooler on a Ryzen 2600X and an EVGA FTW2 1070 Ti along with three NZXT case fans and I can barely tell the system is running now when it's idle. If you want a silent or near-silent PSU then this certainly ticks the boxes. The PSU itself is semi-modular, and at least on the 500W model (and up I presume) the pair of 8 pin power cables for the GPU are separate (instead of one cable that splits into two connectors like some power supplies). Mine came with a Euro plug in the box, so you may want to ensure you have a UK lead handy if you're buying this in the UK.

### ⭐⭐⭐⭐⭐ Good quality
*by I***Y on 29 August 2020*

Plus points 600w is enough for a single GPU Semi modular (What's the point of fully modular?) Gold rated efficiency Good range of supplied cables Replacement cables can be obtained from Be quiet! It's quiet! Negative point Only supplied with a Euro round pin lead (I had to buy a UK lead separately)
