Corsair RM1000x 1000W Power Supply - LABS Test Report

Duration: 03:53

The Corsair RM1000x is a 1000W fully modular, ATX form factor, ATX 3.1 power supply. It offers a single hybrid fan mode and was launched in 2024 with a MSRP of $189.99 USD.

This model (CP-9020271-NA) has been updated to be compliant with the newest ATX 3.1 version, supporting PCIe 5.1, and the inclusion of a 12V-2x6 cable ensures it can handle high-wattage GPUs, providing up to 600W. The 2021 version (CP-9020201-NA) can still be found through various online retailers, it is not ATX 3.1 but is sold under the same name — RM1000x.

We are recommending the Corsair RM1000X for its high efficiency at low loads, and good overall performance across all tests.
