### ⭐⭐⭐⭐⭐ Review
*by E***A on 18 December 2022*

Concerning the Corsair RM1000e. I did not expect to like this PSU, but it has completely exceeded my expectations. This PSU will fit in a very large variety of cases because it *so* small (even though it is 1KW rated). It has been very quiet and efficient, bringing my idle power down from 175W to about 100W. The PSU fan does indeed turn off/on occasionally but you can't hear this. It is replacing an Antec 550W supply which was larger, less efficient and noisier that this Corsair PSU. The system functions perfectly with this Corsair PSU and even seems more stable with the Corsair PSU than with the Antec PSU. For me, the cable lengths weren't perfect (better if a little longer maybe 10%) and the cables were bit on the stiff side (finer wire gauge strands would help). A little more spacing between the SATA/Berg connectors would be good too. I was though, able to neatly dress the cables. My motherboard BIOS shows the 3.3v to be 3.25v or 1.5% low with the rest being perfect. I didn't measure the 3.3v with a voltmeter so it could be an inaccuracy in the motherboard A2D but still well within spec (the fact that system is more stable says a lot). The lack of ARGB (or indeed any lighting) was a plus for me. :) I have been lucky with Corsair in general but for me, this PSU works better than I expected. It's a keeper. -- Update after using for a month -- Still good. I have 13 fans in the system. Of these there are 6 push/pull fans on the AIO cooler and 4 chassis fans. These 10 fans are running on PWM controlled by mobo/cpu temp (running at very low speeds). There is one PSU fan and two GPU fans that are controlled by the respective devices. The system is overall extremely quiet but in low ambient noise situations both the PSU (intermittently runs) and to a *much* less extent, the GPU fans (always running) are somewhat noticeable though not by much. IMO, it would be better for PSU fan to not stop but run very slowly since the noise change from slow to running would be less noticeable than off to running. Even though it is very quiet, the PSU fan is the noisiest one in the system. I still recommend this supply because it is compact, still quiet and provides good power (improved my over-clocking by 100MHz).
