Xilence Power Quiet PSUs
Like most recent power supplies, these Xilence Power PSUs are fitted with a 120mm fan. This produces higher airflow at lower noise levels compared to a 80mm fan. The noise levels generated by these PSUs are very favourable. Starting from just 19.5 dB(A) and reaching a maximum of only 24 dB(A), these power supplies remain very quiet even when under high load.
All PSUs feature Molex plug easy-grip connectors, allowing the user to remove any plug with little hassle. See the specification table below for a full list of available connectors for each PSU.

What a bargain. Easy to fit, super quiet, absolutely awesome purchase. Confused about the ATX 2.2 connectors with my ATX motherboard, but figured it out. Well built, great design, highly recommended

This power supply is well built and stable and at first it seems quiet enough. However running for 30 minutes with around 60% load the fan picks up speed and its certainly not s(x)ilent. I've had standard non-spec PSUs quieter. Disappointing. I've got 2 on these on identical PC's and they're both the same.

Overall this PSU has been good and quiet for a reasonable price, but just recently mine has started to sound like a tractor at times, some problem with the fan. It seems that the spindle is rubbing on something or providing some sort of restriction which is causing noise. Maybe the grease has worn away, who knows, anyway I've had this unit for 2.5 years so its out of warranty. There's always going to be a duff here and there and like I say it has worked well up till now, so just putting this out there as feedback on my experience.

Very pleased with my purchase. I was having a lot of trouble with my PC when a knowledgeable acquaintance suggested it might be a faulty PSU. The new PSU was a piece of cake to fit. The only worrying bit was trying to figure out why the PSU had a 8 pin ATX 2.2 connector and my motherboard had 4 pins. In the end I crossed my fingers and hoped for the best and discovered it plugged in no problem and just left four holes on the PSU connector unused. The PC now works a dream and is very quiet.

This is a good PSU and fairly quiet but I can still hear it! I previously had a unit which was totally silent so I'm probably more sensitive...

I bought this PSU as a replacement for a faulty Coolermaster I had. I was hoping it would be quieter than the old unit and i was astonished I thought the power button on my pc had broken there was almost no noise what so ever. Well impressed with Quiet PC will use again for sure!!
