Corsair CP-9020178-UK RM650x 80 PLUS Gold 650 W Fully Modular ATX Power Supply - Black

Product Information

Nonetheless, the RM650 scores higher efficiency under super-light loads and it also supports Windows 10's Modern Standby mode. We would like to see higher than 70% efficiency with 20W load, though the PSU performs well in the other three tests. On top of that, it uses a micro-controller in the fan control circuit so Corsair can easily tune the fan's speed and provide the ideal fan speed profile. The RM650 uses a 140mm Hong Hua fan and Chinese Elite caps, while the RM650x is only equipped with Japanese caps and the high-quality NR135L fan.

There are several actions that could trigger this block including submitting a certain word or phrase, a SQL command or malformed data. Unfortunately, we didn't test the EVGA 650 G2 with 115VAC input, so we can only compare the RM650x to EVGA's 650 P2. PLUS Gold efficiency reduces operating cost and excess heat, and Zero RPM fan mode ensures virtual silence at low and medium loads. said:for all the good listed in this article, this series of psu just gets bashed in the fourms, just interesting. In the table below, you'll find the power consumption and voltage values of all rails (except -12V) when the PSU is idle (powered on, but without any load on its rails), and the power consumption when the PSU is in standby mode (without any load, at 5VSB).We measured acoustics from one meter away, inside a small, custom-made anechoic chamber with internals completely covered in sound-proofing material (be quiet! Tom's Hardware is part of Future US Inc, an international media group and leading digital publisher. Then again, the 650 P2 is a Platinum-rated PSU while the RM650x only satisfies the 80 PLUS Gold standard. Even overclocked to the max with those parts and both bits under a heavy load you will barely breach 450 watts. Just off the top of my head Flextronics, CWT and SuperFlower are all capable of making units that are at least equal to high end Seasonic quality.

It is true you want a quality power supply period, more so for overclocking, but suffice to say your RMx unit is fine even when overclocked.In the following tests, we measure the RM650x's efficiency at loads significantly lower than 10 percent of its maximum capacity (the lowest load the 80 PLUS standard measures).
