    • The RM1000x is an excellent PSU with individually sleeved cables.
Style: RMx (2024) - ATX 3.1 Size: 1000W
I bought this Corsair RM1000x ATX 3.1 (2024) PSU to replace a faulty ASRock PSU. As one other review mentioned, the Cybenetics rating on the box for power efficiency has been recently updated from Gold to Platinum, which will help keep long term energy costs down for people who live in areas with expensive electricity. When unboxed, the power supply feels and looks like a premium product, and indeed it is. The modular cables in the box all come with individually sleeved wires, and the 12V 2x6 connector and ATX 24 pin connectors come with clamshell style cable combs preinstalled, which seems to be a newer development with this unit. I looked at multiple tech site reviews of this power supply and the only one with cable combs I found was the Kit Guru review, and those were manually installable traditional style combs. The cables did have a bit of a petrochemical smell to them, but it was far better than the ASRock unit I replaced. The cables on the RM1000x are also longer and more flexible than on the ASRock unit, making routing in my mid-tower case easier, specifically for the CPU (length) and ATX 24 pin (flexibility). The power supply performs exceptionally well, making absolutely no coil whine noise at any load, and works completely silently at loads below 500 watts. The fan control knob on the back of the unit comes out of the box set to 0 RPM low noise mode, leaving the fan off until the aforementioned 500 watt limit is exceeded. If you don't care about 0 RPM low noise mode, you can adjust the knob clockwise until it clicks, at which point you're manually controlling the fan, allowing you to set a constant fan speed anywhere in the fans RPM range. One thing to note is that the 12V 2x6 connector that comes in the box only has 2 of the four sense pins, but this is totally fine, as it powers my RTX 5080 without issue, so don't be concerned that two sense wires are "missing". I was extremely lucky to get this unit at a cheaper price only a day before it raised to its current price, but even around the $200 mark, this power supply is worth the price. Overall I give this power supply a 9/10, and only because I don't like that the fan is gray instead of black, which honestly is likely a complete non-issue for most people. ... show more
