Epilogue
It was high time for Corsair to release the ATX v3.1 compliant RMe line. The RM1000e unit’s overall performance is in the ballpark of similar priced and spec units, but it is lower notably than the RM1000x unit’s performance. This is done on purpose, of course, since there has to be a clear distinction between the lower-priced RMe line and the RMx one. With a better transient response at 12V and 3.3V, this platform could achieve a higher overall score, and the APFC converter’s circuit needs an improvement also to offer higher PF readings. That said, load regulation is tight at 12V, ripple suppression is good, the average noise output remains pretty low for a 1000W unit, and I didn’t face any issues during the demanding ATX v3.1 transient response tests. Lastly, adjusting the protection features and having a larger distance between the cold and hot triggering points would be nice. Typically, a PSU is stressed way more under high temperatures, so it only makes sense to have lower OCP and OPP triggering points under stressful conditions than normal operating (temperature) conditions.
The RM1000e (ATX v3.1) will be a fine PSU for the newly introduced NVIDIA RTX 5000 series graphics cards. If you need higher performance, you can spend 20 bucks more and get the RM1000x (ATX v3.1) model. There are also other interesting offerings in the 150-180 dollar range, which you should explore before you decide to invest in a new ATX v3.1 PSU.

Hi! I am tempted to buy the Asus Rog Strix 1200w ATX 3.1, but after reading your review I got a bit discouraged, I’m between the asus, the nzxt c1200 and the corsair RM1000x, which do you think is best for something like the RTX 5090? Thank you!
