As expected, given my experience with the RM1000i and RM750i, the RM1000x performed very well with its most notable features being its high efficiency at light loads, its tight load regulation on the minor rails, and amazing ripple suppression. This CWT/Corsair platform delivers highly competitive performance even without the digital circuits that offer partial control and full monitoring capabilities. However, for another $10-$20, which depends on running rebates and offers, for the RM1000i, I would definitely buy the latter as it not only comes with Corsair's digital interface but a higher-quality FDB fan. With that said, Newegg was selling the RM1000i for $170 and the RM1000x for $145 during the time of review, with an added rebate on the latter which lowered its price to $120, a price tag I would call a steal for a PSU with such a feature set and such high performance. I just wish we had such low prices on these components in the EU, but everything is significantly more expensive here than compared to the US.

Corsair managed to push the performance of these new RM units to another level, and currently, RMi and RMx members have no problem at all in competing with the high-end competition in their respective categories. Compared to the RMi line, the RMx line has an additional member with 550 W capacity, which has the line address an even wider range of users. If you belong to those who just want to install a PSU to forget about it because you don't like to mess with PSU-monitoring or control options, an RMx model will serve you very well and for very long, offering you the peace of mind that is due to quality components and a seven year warranty. Yet if you are an enthusiast user, or one who wants to know more about the PSU, an RMi unit might be a better option, and finally, if you are a control and gadget freak, you should probably put your money into a high-capacity AXi unit for a near-complete digital platform.

In any case, the RM1000x is a fine PSU of very good build quality and performance, and it will fully cover the needs of a strong system with energy hungry components. Corsair has managed to establish a good name for itself in the PSU market, among others, and I personally like the fact that the company is constantly thriving to offer something new or just different to meet the needs of specific user groups. When you listen to the needs of users, you are definitely on the right path. Since I am very picky with the products I evaluate, I did manage to find a couple things in need of improvement with the RM1000x. In my opinion, the most significant of these is the lack of a way to test the fan's proper operation, and I expect Corsair to take a look into this matter with the platform's next revision. It might not be of high importance, but is surely an additional protection feature for those advanced users who want to check on their PSU's fan periodically.
