Corsair has been known for their power supplies for quite some time now, but the original RM series released in 2013 proved to be a popular choice for its 80+ Gold efficiency, Modular cables, and zero-RPM fan modes coming in at an affordable price. If it’s not broke, don’t fix it right? Well, quite a bit can change in the PC world in six years and that gives Corsair the opportunity to polish what was already a popular product. The 2019 update to the RM series starts with three models, the RM650, RM750, and RM850. Most of the features you’ve come to love to remain like the fully-modular low-profile cables, but the warranty doubles to 10 years, and the price drops. Corsair also has some new tricks up its sleeve like support for Windows 10’s upcoming Modern Standby feature. Is there anything not to love? Let’s find out!
