I bought the wrong size but it was really good quality and ive used it before and it’s definitely worth it for both power and aesthetic

Recently I started making some upgrades to a PC I built a few years ago and I obviously had to start with a new power supply to make sure the rest of the new hardware would run smoothly once I had it installed. This Corsair RM850 has met all of my expectations and has run super quiet, which was really important to me. It installed really easily, and having things labeled made getting my entire system connected and back up and running a really smooth and quick process. If you're in the market for a reliable power source that won't break the bank, I would definitely recommend this one.

Works for my set up, easy to install. Looks fantastic in the tower.

It arrived on time, and it does it's job well. No issues so far, and the white really fits with the aesthetic of my PC. It came with a bunch of extra cables that I didn't need.

I was in the middle of gaming and my power box exploded, so this came in handy it’s really good.

Good power supply with white cables to complete the clean look in a white amd black case. No issues and works as intended.

Love it, I got white even though you can’t really see it in the case because I know it matches

Loving the white cables to go with the full white build. Only things I can say are just positive. Brings plenty of cables for the basic items in a regular build.

Corsair quality power supply. Wish I would have gone a bit larger to be able to support the new 4 series gen GPUs but handles the 3090 without any issues.

The RM850 power supply from Corsair is a beast! The 80 PLUS Gold efficiency ensures stable power delivery, and the fully modular design keeps cable management a breeze. With 850 watts, it's a powerhouse capable of handling demanding setups. The Zero RPM fan mode keeps things quiet during low loads, and when it kicks in, it's still impressively silent. Whether you're a gamer or a content creator, the RM850 is a reliable and robust choice for powering your rig.

More than enough power! easy to connect and use. would recommend to anyone wanting a good power supply for a good price.

This power supplier is great for the Graphics card I bought for my desktop.

Good psu I like that it came with white cords but i still got cable extensions for a cleaner look, corsair is a reliable brand.

I needed a power supply unit that would fit my HYTE Y60 case and this did the job perfectly. Output of power is great. Great price too.

Works amazingly this is defenitly stupendesly the best purchase ever

So many cables! Loved that when I was installing, I had so many options for cable management. Nice and quiet too!

Premium product. Slightly expensive but anything computer related and white usually is! I use it with my Ryzen 5900x and EVGA XC3 Ultra 3080 and it’s more than enough juice.

I needed a new power supply so I had happened to pick this up from best buy. So far I'm satisficed with how quiet the power supply runs when I turn it on and it looks beautiful in my computer

I always go Corsair when building a rig. This is a powerful PSU that can handle some of the most top-of-the-line rigs out there!

According to the PC Cultists tier list, this PSU is as good as it gets at this price point, but worth waiting to go on sale
