Corsair RM1000e (2023) Gen5 PSU Review

Box & Bundle

Corsair made the difference all these years in the PSU market and continues now by being among the first, along with SilverStone, to get away from the 80 PLUS scheme and, for the first time, only use a Cybenetics badge at the face of the box. The provided protection is good at the internals thanks to a pair of foam spacers. Lastly, the bundle includes some zip ties, a set of fixing bolts, and paperwork, besides the necessary cables.

The PSU is compact, with only 140mm in depth, so a 120mm fan had to be used. The fan grille has large perforations, so I am not worried about airflow, and the exhaust grille also has large enough perforations to allow the hot air freely exit the PSU’s internals.


Modular Cables
Description Cable Count Connector Count (Total) Gauge In Cable Capacitors
ATX connector 20+4 pin (600mm) 1 1 16-20AWG No
4+4 pin EPS12V (650mm) 2 2 18AWG No
6+2 pin PCIe (600mm+150mm) 2 4 16-18AWG No
6+2 pin PCIe (600mm) 2 2 16AWG No
12+4 pin PCIe (650mm) (600W) 1 1 16-24AWG No
SATA (500mm+100mm+100mm) 1 3 18AWG No
SATA (450mm+115mm+115mm+115mm) 1 4 18AWG No
4-pin Molex (450mm+100mm+100mm+100mm) 1 4 18AWG No
AC Power Cord (1400mm) – C13 coupler 1 1 14AWG

Two EPS connectors on dedicated cables, four PCIe 6+2 pin on two cables, a single 12VHPWR set at 600W, seven SATA, and four 4-pin Molex connectors. You won’t need more SATA connectors unless you want to build a server, and I would like to see a longer distance between the peripheral connectors.

  1. I’ve noticed quite a few reviews of this PSU, both online and one person I know personally, which have reported really bad coil whine issues just by turning the PSU on. I’m wondering if there was a large bad batch that went out and the rest are fine or if this is a bigger problem. Regardless, I’m really glad to see a slightly more budget series from corsair to slip between their cxm and rmx series assuming this coil whine issue isn’t widespread.

    1. This is a new product, just got released, so you probably refer to the previous RMe. We didn’t notice any strange issues in our tests, and we have tested almost a dozen different RMe models.

  2. Hello Aris,
    The soldering it’s bad as it can be. Off centered and off axis SMD, cold joints and manual soldering for some parts. High Power parts with half the flux.
    You call this “Average soldering quality”? This thing it’s a fire hazard waiting to happen.
    BTW can you give an example of bad soldering in your reviews?

    1. Hi there! This unit is a fire-hazard? It passed hours of testing under the toughest possible condition without breaking or creating any issues.
      Where did you see cold joints? If a joint is cold, the unit wouldn’t work at the first place.

      Believe me this is average to my eyes. For me notably problems are mostly long component leads which can create shorts and when solder is missing, creating poor connections and increased resistance.

      This is bad soldering example:

      1. The manual soldering done on some SMD parts point me to this cold joints issue, if the QC misses one then here you go.
        Also too little flux for the FET’s could lead in time to a crack. Those parts get thermal cycle all day long.
        Remember the we don’t buy PSU’s for 1-2 years.

        Yeah the example is real bad, thanks for sharing.
        Keep up the good work man.
