Rating: 8.0.

Today we are looking at the latest Pure Power 630 watt supply from German market leaders, BeQuiet. This company focus on creating a quality power supply with the lowest possible noise emissions. The ‘L8’ version is the 8th iteration of the series which is 80 Plus Bronze certified with a very high quality, custom designed fan called the ‘Silent Wings’.

Be Quiet! have actually built up a well earned reputation as an ideal choice for a media system build, thanks to their class leading fan production. There are four power supplies in this latest range, a 430 watt, 530 watt, 630 Watt and 730 watt. We are analysing the 630watt model today. Be Quiet! have used FSP as a partner for a long time now, but this range is an HEC design.

Be Quiet! have expanded their product awareness in the United Kingdom recently with stores such as SCAN offering their products at competitive prices. They offer a full three year warranty with this range of products, for peace of mind.

    They look very sporty, nice idea about the elastic, never seen any other maker doing that before?

  • Tony

    They make great products, fantastic to see them being reviewed here. I bought one last year (not this review product obviously), and its been running like a treat, inaudible.

    It looks like they have further improved their fans. might contemplate an upgrade soon and sell my own on ebay

  • Raymond

    So many power supplies to choice from, but I think people are finally paying more attention to what they should or should not buy. and doing research before buying a non name brand in a store. I upgraded recently to a corsair unit and its a little louder than I thought actually. I should have researched better myself.

  • Lennn

    Good german quality make. good review.

  • Peni is huge

    Never heard of them, checked out their website, I see they do a lot of othter things too, like enermax. how do they compare against enermax?

  • Manny

    WEird, I always thought they worked with FSP as an exclusive partner.

  • Optix

    Its good, but the latest designs with the ‘fan not spinning’ up to xxx output are actually better for media centers. Corsair and PCPOWER cooling make a few, which were reviewed here months ago.
