bequiet! Pure Power L8 400W Review

Rating: 8.0.

Today we are looking at the latest power supply from BeQuiet!, the Pure Power L8. We analyse the 400W model which features an ultra low noise SilentWings fan and 80 Plus Bronze certification. These designs can deliver around 90% of their total power on the +12V rail. The Pure Power 8 range features six safety circuits and Taiwanese capacitors with a product warranty covering three years.

The bequiet! Pure Power L8 range of power supplies are a new non modular series targeting the widest audience at the lowest possible price. Previous models in the family had a ‘CM’ moniker after the name, this stood for Cable Management which was basically a fancy way of saying ‘modular’.

The 400W model we are reviewing today has a recommended retail price of £47 inc vat and on paper should be an ideal partner for a low cost media center.

Dedicated gamers will probably be looking at the Pure Power L8 600W and 700W models, which are competitively priced at £67 and £76 respectively.
