Final Thoughts

It has been ages since we have seen a power supply from Corsair that even hinted that it was anything less than of superior quality. Even then, it was a bare bones entry level unit that was simply designed to get you by and nothing more than that. Corsair continues to prove that their power supplies are all you can want in a unit and sometimes more, and the RM1000x is no exception to this.

The RM1000x is a unit that displays superior performance characteristics all the way around. From a voltage regulation standpoint, even though the voltages are only within 2% tolerance of ATX specs, they are very stable and display minimal changes from low to full loads. Heck, the 12V rail even stays within 1% the entire time. When you look at the DC Output quality of the unit, you simply can't ask for anything better. Even then the Corsair AX1200i and Corsair AX1500i barely perform better and you really have to zoom in on the scope to see the noise. Even from an efficiency standpoint, the unit stands very strong. I have a feeling that the only reason that this is an 80 PLUS Gold rated unit instead of Platinum is that they were trying to keep the cost down.

The RM1000x is priced about $20 cheaper than the RM1000i, and this is because it does not contain the digital monitoring capability of the RM1000i with integrated Corsair Link, but still maintains their seven-year warranty. I've been using Corsair's Link enabled units for quite some time, and aside from when you are trying to do some serious overclocking or troubleshooting, it isn't a necessary feature. Shaving a few bucks off a power supply but still maintaining great quality is a great idea and it is money that can be devoted elsewhere to the system for faster performance.

When it comes down to it, this is what matters to most as they are trying to build the fastest machine possible for the budget they are given. Few have unlimited budgets to blow on bleeding edge everything, and it does matter when you can shave a little here and there and still wind up with the same performance. If you're looking for a superior quality power supply but trying to shave a few extra bucks for elsewhere, this RM1000x is just the ticket.

The Bottom Line: Corsair's RM1000x is all about delivering amazing performance while keeping the price down and it is very successful at doing so. Unless you absolutely have to have the Corsair Link monitoring offered by their other models, the RM1000x is an excellent choice for anyone in need of excellent 1000W power supply.
