Corsair RM1000e Fully Modular 1000w 80 Plus Gold PSU Review

How Much Does it Cost?

The Corsair RM1000e Fully Modular Low-Noise ATX Power Supply is available now on Amazon for just £169.99 MSRP. However, at the time of writing it was actually just £152.95. That’s a very reasonable price, and falls in line with the similarly equipped MSI MPG A1000G, DeepCool PX1000G, and Thermaltake GF3 1000W, to name but a few.

Overview

Corsair is one of the leading names for not just power supplies, but peripherals, cases, coolers, and so much more these days, so they have a pretty high and well-respected reputation to uphold. Thankfully, the Corsair RM1000e doesn’t let the side down and delivers a performance that’s right on the money for a mid-range gaming PSU.

It delivers 1000W power, which is more than enough for the most potent CPUs on the market plus any of the latest flagship graphics graphics cards. It’s unlikely that you’ll exceed that power with such a build, but if you are expecting to run at close to the 1000W a lot, then stepping up a model would be advised. If you have any power spikes from a particularly weird moment in a game or rendering spike, the PSU can pull over 1200W for a short while before it cuts out, so again, it’s unlikely to interrupt your system’s performance.

The build quality is very good, and while the inside looked like it was a bit of a buffet of different capacitor brands, there’s clearly nothing wrong with that. The lower load PFC and ripple were pretty good, perhaps only standing out more as I’ve only been testing much more expensive units recently. However, for this price range, it’s still a stable and reliable PSU. I’m equally impressed by the efficiency which was so much closer to being 80 Plus Platinum than it was 80 Plus Gold, which is going to mean less power goes into the PSU to create the required output, saving you money in the long run.

It ran pretty quiet too, even at sustained high loads, I never found the fan ramped up particularly aggressively and seemed to sit comfortably at 800 RPM where it was no louder than a typical PC case fan. At lower loads, such as when I’m writing content, browsing reddit or watching YouTube the PSU is completely silent.

Should I Buy One?

If you’re looking for a competitively priced PSU for your next gaming build, or to simply replace an ageing PSU that doesn’t support the latest PCIe 12VHPWR cables and ATX 3.0 standards, this is a great upgrade. The efficiency, noise levels, and stability make this a solid mid-to-high-end PSU for those needing plenty of power without spending a small fortune.
