## Description

CORSAIR RMx Series Fully Modular Low-Noise Power Supplies deliver quiet, dependable power with Cybenetics Gold efficiency to your PC. Fully modular, ultra-flexible embossed cables make PC builds easy, as you connect only the cables your system requires. Compliant with the ATX 3.1 power standard from Intel®, RMx PSUs have the connections needed to power today’s demanding PC hardware including a native 12V-2x6 connector. 100% Japanese 105°C-rated electrolytic capacitors deliver fantastic electrical performance, while a 140mm FDB fan provides low noise cooling. Backed by a ten-year warranty, RMx PSUs are the gold standard for many years to come.

Review: Top-tier internal components, Platinum-certified, Stable - Excellent power supply. I previously had a 2017 RM850x with very thick cables that were a nightmare to manage. Now, 9 years later, I’ve upgraded to this RM1000x, which has very flexible and easy-to-route cables. Surprisingly, I received a Platinum-certified unit instead of the Gold one! This PSU stands out for its top-tier internal components (excellent element base). It’s dead silent, runs stably, and shows no voltage drops. The only downside is that it only comes with 2 cable combs
Review: With great power comes great peformance - It's a great power supply. Modular and not too big of a unit. I'm using to to power an Intel 14900K CPU and Geforce RTX 5080 GPU. It also powers a handful of peripherals. It does the job with plenty of power to spare. I especially appreciate the native 16pin GPU connector. Don't hesitate and just buy it. You won't regret it.

- Fully Modular: Reliable and efficient low-noise power supply with fully modular cabling, so you only have to connect the cables your system needs.

### ⭐⭐⭐⭐⭐ Nice cables and low noise
*by A***. on April 29, 2026*

Only owned this power supply for about 3 days but I really like it. its quiet and I really like the cables. I also own the 750watt version and the cables seem way cheaper and harder to work with. while this unit has each wire sleeved individually the whole cable is sleeved in the 750 watt version making it hard to bend and do any wire management. i mostly got this powersupply because i bought a used 3080 that needs 3 pcie for its power and my motherboard also requires 3 aswell. 2 for the cpu and one for the board itself. this is a very good power supply if your kind of still wanting to use your old pc parts with a new power hungry motherboard/cpu while also still has a new 12V-2x6 port/cable. very happy. if the power supply fails or something else ill do a edit and update this review.
