SilverStone Internal Power Supplies SST-EX850R-PM Editorial Review
The SilverStone Technology Extreme 850R Platinum is a reliable power supply unit that is fully compliant with SFX12V 4.0 (equivalent to ATX 3.0) specifications. It provides higher peak power and more responsive sleep/wake performance. The unit has a semi-fanless feature that enables the fan in the PSU to stop spinning up until around 200W, which makes it quiet during low loading conditions. The Extreme 850R Platinum comes with an 850-Watt capacity and one PCIe cable with two PCIe connectors. However, it lacks an additional PCIe cable, which could be a problem for those who require two connections for their GPUs. The provided 12VHPWR cable is incorrectly labeled for some units, but SilverStone provides a solution for customers to exchange the cable. Additionally, it is not recommended to use cables from the SilverStone SX1000 unit with this unit as they are not compatible.
