Conclusion

Corsair aces each of those metrics with the RM850x (2021)...

Having a high-quality PSU pays dividends build upon build. We'd recommend a fully-modular design touting at least 80 PLUS Gold Efficiency, rock-solid voltage regulation and ripple suppression, all wrapped up in a chassis housing a high-quality fan able to run in semi-passive mode.

Corsair aces each of those metrics with the RM850x (2021). Featuring the premium ML fan for the first time, there's a lot to like. It's also aimed at the HEDT crowd through provision of three 8-pin CPU connectors for this capacity, offers consistent performance across the board, and at 160mm deep, ought to fit into most chassis.

Available on pre-order for £130 and certainly competitive against other premium supplies, it's a good shout for your next system upgrade or premium build.

The Good
  
The Bad

10-year warranty

I've one of these in 750W after my old PSU was getting to something like 9 years old (I forget the exact number but it's still going in someone else's system) and reliability was essential along with needing more chooch for the Vega64. PSUs aren't sexy, but a cheap one is gambling a hell of a lot on a primary system or an expensive build. Having seen a few reviews of these and even Anandtech raving about them, if you see one on offer, and you're on a potentially weak PSU, they're worth getting. The cables are a little bulky with the caps in but that's only a problem if you're in a SFF or have some weird cable routing to contend with. Myself, I barely noticed but my case is the size of a bus.
