Introduction & Packaging
Corsair have been known to produce some of the best power supplies in the business and today, they look set to continue that trend with the release of their high-end RM1000x. Not everyone needs 1000w of power, of course, but when you do, it’s likely that you’re also the kind of system builder who demands the best performance from your components. Previous high-end PSUs from Corsair have reaped some of the best results we’ve ever seen, with ripple so low we thought there was an issue with our testing equipment, so to say we’re a little eager to see what this one can do would be quite the understatement.
“Corsair RMx series power supplies give you extremely tight voltage control, quiet operation, Gold-certified efficiency, and a fully modular cable set. Built with all Japanese 105°C capacitors, they’re a great choice for high-performance PCs where reliability is essential. 80 PLUS Gold efficiency reduces operating cost and excess heat, and Zero RPM fan mode ensures virtual silence at low and medium loads. And, the fully modular DC cables make builds and upgrades easy, with clean, great-looking results.” – Corsair

Equipped with all the usual safety features you would expect, as well as 80 Plus Gold efficiency, all Japanese capacitors, a ZeroRPM mode, a powerful 135mm fan, fully modular cable design and more, the RM1000x certainly ticks all the right boxes and to sweeten the deal, Corsair has given it a 7-Year warranty! That last part fills me with a lot of confidence.
1000W is a lot of power, more than enough to power an extreme workstation or gaming system with enthusiast overclocks and multiple graphics cards. As you can see, that 12V rail can push a very mighty 83.3A, more than enough power for 
The packaging is very nicely designed, with a big and clear shot of the PSU on the front and that stand-out black and yellow Corsair branding.
Around the back, a quick technical rundown of the efficiency, hybrid fan mode and connectors.
There’s quite a lot of stuff in the box, with a durable protective bag for all the modular cables, a soft bag with the PSU inside, heavy-duty power cable, cable ties, screws, and all the usual documentation.
