🚀 Abunda's Overview

This is our summary and key points to consider based on customer reviews.


The Corsair RM850x fully modular power supply unit (PSU) has been praised for its excellent efficiency and silent operation, with notable features including an impressive low-noise fan, exceptional power delivery, and a great build quality. One unique factor to consider, however, is the design of its shift model, specifically suited for side-mounted PSU slots; this may not be compatible with some cases and can present wiring and heat dissipation challenges.

Pros

  • 👍 High-quality build, solid, and durable
  • 🌟 Excellent power efficiency and power delivery
  • 🔇 Very quiet operation, with Zero RPM fan mode
  • ⚙️ Great modularity allowing for easy cable management

Cons

  • ⚠️ May not fit into smaller PC cases because of its size
  • 🔄 In the Shift model, side out connector may not be intuitive for some setups
  • 💼 The Shift model might cause some spacing issues in narrower cases
  • ⚡ Potential heat dissipation challenges due to wiring placement (again in Shift model)

Should I Buy It?

If you're seeking a high-quality, highly efficient PSU that offers seamless and quiet operation, the Corsair RM850x undoubtedly fits the bill. However, be mindful of whether the fully modular design suits your particular PC case and setup. If you're considering the Shift model, ensure that it fits with the space and wiring layout of your case. Overall, this PSU is certainly a worthwhile investment for tech-savvy users and gamers.


  • Great and durable PSU
Style: RMx (2024) - ATX 3.1 Size: 1000W
It does its job and provides power to my PC components with a fantastic gold efficiency rating. This version is also smaller than Corsair's previous 1000 watt PSU, but have had no troubles of overheating at all. The fan control knob is also a nice feature to have if you really want to control the speed of your PSU fan. Cables are also easy to connect and disconnect with no problems at all and the dedicated 12v-2x6 port is great to have since it lessens the amount of cables needing to connect to your PSU. ... show more

  • Solid Power Supply for My Gaming Rig – Quiet, Reliable, and Powerful!
Style: RMx (2021) Size: 750W
I recently installed the CORSAIR RM750x Fully Modular ATX Power Supply in my gaming machine, and I have to say, I’m pretty impressed. First off, the fully modular design is a game-changer – no more cables cluttering up my case. I only used the cables I needed, making cable management a breeze. The 750W is more than enough to power my setup, and it runs super quietly – I barely hear a thing, even during intense gaming sessions. It’s also got plenty of headroom for future upgrades, which is great. Overall, the RM750x feels like a top-tier power supply – solid, reliable, and built to handle the demands of a high-performance gaming machine. If you're building a gaming rig and want something that won’t disappoint, this is the one to go for. Just plug it in, sit back, and let the power flow ... show more

  • Worked perfectly... no issues.
Style: RMx (2021) Size: 850W
Easy to install, quiet. Overpowered for the system, but may be okay if I ever install a big graphics card. Very happy so far. FWIW, use the cables that come with the power supply. I tried using some of the cables from the previous PSU and something didn't work right. Feels robust, and plenty of power. ... show more

  • Good price, easy install, works great
Style: RMx (2024) - ATX 3.1 Size: 850W
I got this to upgrade my Alienware R11. Fits perfectly, works fine. It comes with a LOT of cables, and not only those, but tie-wraps, wire looms, even color-matched mounting screws. No instructions, but they aren't necessary. The ATX spec connectors can't be plugged into the wrong things in general, they're all keyed differently. My only gripes, the cables of course come in a standard length, too long for any of my connections. But, that's what the tie-wraps are for. I wish the SATA power cables included some right-angle ones, cover on the R11 is a very tight fit if you have one of the extra disk bays populated. One final thing, there's a knob on the back of the supply with no description of what it does. Well, it sets the minimum fan speed. In the 'off' position, it enables zero-RPM automatic mode, which is what should be used. Otherwise, it sets an always-running minimum speed that can increase automatically. ... show more

  • Works as expected
Style: RMx (2024) - ATX 3.1 Size: 850W
I was gonna buy the previous version of this model when i saw this one come up , it is very convenient with its new port! I recently needed to upgrade my pc from my old GTX 1060 6gb to a 4070 super and my old 600 psu was definitely not enough. My new GPU has the new nvidia power port and this power supply comes with a nvidia 12pin built in so i dont need to use a dongle of 2 pins to a nvidia 12pin. Also comes with the cable i need to power my new GPU. It very quiet havent noticed any weird noises and fan is very quiet. The build quality is great and the cables have a decent texture to them. ... show more
