CORSAIR RMe 2025 vs RMe 2023: What’s new

At CES 2025, we debuted the 2025 revision of the RMe series of PSUs. While the new models share the same name and similar appearance as the previous versions, we want to take a moment to highlight the key differences.

First, we'll compare the specs to get a proper apples to apples comparison.

For most users, the most relevant upgrade that we've made to the 2025 version of the RMe series is the addition of a native 600W-capable 12V-2x6 connection. This makes the PSU ready for the latest GPUs, including the RTX 50 Series.

We’ve also made the plug for this cable light gray, so you can easily tell if the cable is properly seated or not. If you can still see gray, then the cable might not be fully inserted.

Another benefit of a native 12V-2x6 cable is that it takes up less space on the PSU side, so you have more connectors available, and it’s easier to cable manage.

In short, the 2025 RMe PSUs adhere to the latest PSU standards, with PCIe 5.1 improving power efficiency and signal integrity. They are also more reliable with built-in ECC (Error Correction Code). ATX 3.1 provides a shorter hold-up time, which improves efficiency, and the 12V-2x6 port features shorter sense pins. This makes the 12V-2x6 cable more robust, as the sense pins won’t connect unless it’s properly inserted.

Basically, you don’t need to worry about any of this from a user-experience perspective, but you can rest assured that your power supply is as up-to-date as possible.
