Corsair RM1000e (2023) Gen5 PSU Review

The RMe series is more affordable than the RMx line, offering in its newest revision ATX v3.0 and PCIe 5.0 compatibility. The RM1000e uses an efficient platform and it also has a silent operation. Performance wise, don’t expect it to be close to the RMx line, because this would create internal competition. 

Corsair’s RMe line with ATX v3.0 and PCIe 5.0 compatibility makes its debut today. This line has three members with 750W, 850W, and 1000W max power. All feature 12VHPWR connectors, which can handle NVIDIA’s newest GPU offerings. The RMe line is taxed below the RMx (Shift) one in terms of performance and price, and this is why Corsair used a different OEM for these models, HEC, while CWT makes the higher-end models. All RMe units have a single 12V rail, which is what most users prefer for quite some time now, and the retail prices are $140 for the 750W model, $170 for the RM850e, and $242 for the RM1000e. Typically, the street prices will be lower than the MSRP ones. For example, I found the RM1000e at $171 on Amazon, a huge difference from the MSRP. Corsair uses the “2023” prefix for the new RMe units to distinguish them from the older version. Another way to distinguish the new model is the Cybenetics badge at the face of the box!

  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.
