PC cooling firm be quiet! has released its latest line of PSUs, the System Power 9 SM series. The new PSUs are semi-modular with two independent 12V rails, and are available in capacities from 400W to 700W. There’s also the capacity to connect up to four PCI-E connectors for multi-GPU systems.
As the company’s name suggests, the CM series also boasts ‘very quiet operation’, with cooling handled by a thermally-controlled quiet 120mm fan. Meanwhile, neat, sleeved cables help keep down the clutter. The CM series is certified 80 Plus Bronze with up to 89 per cent power conversion efficiency, and they possess an array of short circuit and surge protections too.
The 700W version of the System Power 9 CM Series retails for £85.49, with the 600W costing £73.99, the 500W at £63.98 and the 400W at £52.99 (all prices inc VAT).
