Video reviews

remix time

In 2015, Corsair updated its RM power supply line twice, which the company thought were good, but not perfect. First, the RMi line entered the market, which used high-quality Japanese capacitors and added the Corsair Link system to monitor the status of the power supply. Not everyone needed this thing, so a little later RMx power supplies arrived on the shelves with the same element base and Japanese capacitors, but without Corsair Link. It is about this model that we will discuss in this review.

Efficiency 92%

According to the passport, the model has a power reserve of 650 W and boasts an impressive efficiency of 92%. In fact, it turns out even better, since at a rated power of 650 W it coped with overloads reaching 730 W without any problems, while ensuring minimal output voltage deviations. I especially liked the state of the 12-volt line: no drawdowns, regardless of power consumption, and the ripple level is 2-3 times lower than normal.

10 years warranty

Among other advantages, we note the high load capacity of the +12V channel, the presence of all types of protection, a modular structure and a hybrid cooling system that allows you to switch coolers from normal to silent mode. A useful feature if the computer is used not only for games. Together with a 10-year manufacturer's warranty, this makes the Corsair RMx a reliable base for a powerful workstation or gaming machine with a couple of video cards and serious overclocking.
