MULTIPLE-GPU READY Corsair has grown into a huge company over the last several years, and they are still constantly expanding on all areas they participate in. Especially their PSU portfolio has expanded rapidly lately as we saw Corsair release one line after another, which put the competition into a really uncomfortable position. The fresh RM line is, according to Corsair, optimized for silence, and our experience with the RM750 and RM850 units we already reviewed a while ago confirms just that since both aforementioned units registered very low noise output throughout their entire operating range. We would also like to remind you that the RM750 and RM850 units are made by Chicony while all other RM PSUs are made by Channel Well Technology (CWT), an OEM Corsair has cooperated with successfully for a long time. The RM650 is then based on a different platform than its two bigger siblings, and we are really curious to see how it will perform. The RM Series delivers power at up to 90% efficiency, lowering energy consumption, noise, temperatures, and your power bill. 105°C-RATED CAPACITORS Thanks to the SmartChoke technology, the engine starts up reliably and with minimal effort both during cold and warm starting. Vario self-drive At low loads, the unit only operated in passive mode, putting out zero noise and scoring pretty high efficiency readings on all four tests. What is noteworthy here is that it achieved over 80% efficiency with only 40 W load, which will save you some money if you have your system sitting at idle or very low utilization for prolonged periods of time.

The smooth running wheels of the STIHL lawn mowers are extremely robust and hard-wearing. They have been equipped with a traction pattern and directional stability tread pattern for effortless manoeuvring and to help hold perfect line during mowing. Super soft grip PCI-E connectors to power dual or triple (RM850 only) GPUs for your most ambitious PC gaming builds.
