Review: Be Quiet Straight Power 11 1000W - it is REALLY quiet! - Upgraded processor from Ryzen 3600 > 5900X and have an ASUS TUF 3070 OC as the GPU. Had been using a Be Quiet 600W PSU with no problem but it was both only 80+ Bronze and power limiting. I like Corsair and the reviews looked good. Installation was a little bit tricky as the PSU is bigger than many other 1000W but not an issue. It came with 2 less cables than the manual stated. However, no matter how many checks on hardware and software, there was a significant power coil whine. I use a Corsair 275Q quiet case and want a quiet but powerful pc. The HX1000 was very much louder under 400-500W load than the 600W PSU. There was also a dreadful power coil whine that on researching, is quite common. Have replaced with a Be Quiet Straight Power 11 1000W and this is almost completely silent at idle and barely audible at full gaming. Really can't say more than if you want a quiet pc, these PSUs will do the trick.
Review: Very quiet and outstanding build quality with very good cables - The main thing that stands out to me with this PSU is the incredible build quality, the cables are built amazingly and come in mass! Easy to install, comes with screws too. Barely any noise at all. Would recommend this to anyone looking for an efficient and reliable PSU.

### ⭐⭐⭐⭐⭐ Best brand in the PSU market
*by G***M on 21 August 2022*

Couldn’t be happier. A great upgrade to my old BeQuiet PSU from 2014. Again this one is super silent and, best of all, absolutely zero coil whine unlike many of the big brands. Throughly recommend BQ every time. Powers my RTX 30 and 12th gen setup brilliantly.
