Pure Power L8 500W PSU, BN223

,

I bought this unit to replace my aging 350W PSU that was starting to make too much noise after an hour or two due to the heat, a sign of a failing power supply and the odd BSOD.

I received the be quiet PSU the next day and installed it, plenty of cabling for PCI-E and CPU and drives, good quality cables, even screws, tie backs, and a power cord with the correct fuse was in the box.

After the initial power up of all the fans, the PSU settled to a surprisingly low noise, I could hear the other fans in the case working, the PSU is very quiet, after hours of use the noise level is bearable and lower than any other I have used before, stability is second to none, my PC seemed more responsive and even slightly quicker than before, plenty of stable power to all the components.

Thank you quietpc.com, the customer service was excellent, I received a confirmation of the parcels dispatch and a kindly response to a support question, my PC is enjoyable, usable, and reliable once more, I will certainly order from quiet PC again.

Much quieter PC.

Bought to replace a cheep and noisy budget original. Cabling is heavier than the original and took some time to route comfortably but the case is fairly shallow back to front. Very happy with the low noise level.

This thing is amazing

My old PC, which has been noisy since I first got it in 2006 went from sounding like a jet engine to a very gentle breeze and that's down to the remaining CPU fan - the PSU seems completely silent. Really impressed.
