This is a really quiet PSU. On switch on it briefly runs the fan , as a test, and that's the last you will hear of it!

This 500W power supply is a very high quality product for a very reasonable price. Very easily fitted using the supplied screws and it powered up without any problems. I have used similar products from Be Quiet before (fans and power supplies) and as their name implies they are renowned for their very efficient and silent operation. This product is no exception and the overall build quality is extremely high. All the internal leads are insulated with braiding and bunched logically into 6 branches, so connecting it internally is fairly easy, despite the fact it is not a modular design.

There are cheaper 500 watt PSUs but then there are some important compromises. Firstly this one has 2x 6+2 PCIe power connectors so will connect to the most power hungry GPUs. This is a consideration for me. Secondly this PSU easily powers a high power GPU like an old R9 290 or HD5970 without straining. Not all 500 watt PSUs actually meet their rating. This is probably why the cheaper ones don't have the full set of PCIe GPU connectors. It's to try and stop you using them. If you have to spend 5 on a splitter then you may as well have spent the money on a better PSU. You can probably find a cheaper 500 watt PSU that will do what you need but for what I needed the next one up would have been a 650 watt for a lot more money. That makes this one very very good value. You can also tell it's good quality compared to the ones 10 cheaper.

There are more expensive PSUs than this and there are cheaper ones. Frankly the cheaper ones you'd have to get the 750w version. The more expensive ones have modular cables, which is nice. In most cases you can tuck the unused cables out of the way and save your money for more faster storage. 500 watts will pretty much run any normal computer unless you want two graphics cards or a super high end CPU. I was pleased with the quality of the BeQuiet and it did seem familiar. I reckon it's the same as another decent PSU I have used recently. This is a good choice, just remember it only supports one graphics card.
