be quiet! Pure Power 10 700W CM PSU Review

Rating: 8.0.

Today we analyse a brand new power supply from the be quiet! Pure Power 10 range. This 80 Plus Silver certified 700 watt model is due for release this week and will be priced around the £100 point in the UK. You may have noticed that the model we are reviewing today is tagged with a ‘CM’ – this stands for ‘cable management’ or translated into real world terms – its actually semi modular. be quiet! will be releasing another range of Pure Power 10 supplies with all hard wired cables (no ‘CM’ in name), at a slightly lower cost.


Pure Power 10 CM power supplies with cable management will be offered in 400W, 500W, 600W and 700W capacities and are priced between €72-€115 MSRP. Pure Power 10 power supplies with fixed cables are offered in 300W, 350W, 400W, 500W, 600W and 700W capacities and will be priced between €50-€105 MSRP.

I was hoping be quiet! might have improved the efficiency to 80 Plus Gold Certified levels, from the Silver of the Pure Power 9 series, but sadly not. The certification remains the same.
