Corsair RM1000x 1000 Watt 80 PLUS Gold Fully Modular Power Supply Review

Final Thoughts


The Corsair RM1000X was never going to be cheap, it is a high-end, high-power and 80 Plus Gold rated unit after all. You can pick one up from for £149.95 Inc Shipping, although most  major retailers have them in stock for around the same price.


The latest power supply from Corsair is easily one of the best to date. It delivers big performance that’s going to give their competition a serious run for their money at this price range. In terms of features, it’s certainly well equipped, with a hybrid fan mode that keeps the fan at 0RPM in low-load scenarios, so when you’re working it’ll be virtually silent. The cables design is fully modular, which is going to make your cable routing a whole lot easier while I also appreciate that Corsair has gone with black cables, black braiding and black connectors, as it really helps unify the aesthetics.

Equipped with excellent quality all Japanese 105c rated capacitors, the power delivery is some of the best we’ve seen. The ripple levels are so low that they make a mockery of the ATX 12 volt specifications, which is obviously no bad thing, as it means your system is getting clean power delivery. This is further backed up by the near perfect PFC and the tight voltage regulations, something that is sure to put a smile on the face of anyone overclocking, as stable voltages can translate to more stable clocks.

Build quality is nice and robust and the overall design is certainly pleasing to the eye, meaning it should blend easily into virtually any system build. It is a little pricey, but given that it comes with such impressive performance figures, offering up 1000W of power (and 1250W before OPP kicked in), and comes backed up with an impressive 7-year warranty, we think it’s worth every single penny.
