Corsair RM1000x SHIFT Fully Modular ATX Power Supply - 80 PLUS Gold - ATX 3.0 - PCIe 5.0 - Zero RPM - Modular Side Interface - Black

I recently upgraded to the Corsair RM850x SHIFT, and honestly, the side-mounted connectors are such a smart design. If you’ve ever struggled with plugging in cables in tight cases or near the bottom of your PC, you’ll appreciate how much easier this layout makes everything. Cable management was way cleaner, and it actually gave me more space to work with inside the case.Performance-wise, it’s rock solid. 850W is plenty of power for my setup, and everything has been running super stable. The unit is also really quiet — the fan barely kicks in, even under load, and when it does, it’s still whisper-quiet.Build quality is what you’d expect from Corsair — sturdy, premium feel, and comes with all the cables you need. Modular design means you only use what you need, keeping the build neat and airflow-friendly.If you're building a new PC or upgrading, the SHIFT is 100% worth considering. It’s not just about power — it’s about convenience and clean aesthetics, too.

Great power supply with side mounted connections to make cable routing easier. The unit is very quiet even when under load and appears to be good quality. The cables are non standard smaller connections but the unit does come with everything you require and additional cables can be bought if needed. Makes it much easier to install the power supply in a cramped case as there is no need to struggle trying to fit cables behind the power supply as it can be done with far side panel removed and then just easily plugged in.

I purchased this power supply after spending a week reviewing numerous power supplies online. This PSU is listed as a tier A high end power supply on cultist reviewsI had recently upgraded my GPU to a 7900xtx and my Seasonic prime 850w could no longer handle the power demands put upon it so needed to upgrade.Due to supply shortages and high prices in the UK currently I decided to go for a cheaper option and so far I am glad I chose this power supply.My first choice would have been a platinum or titanium rated Seasonic supply but this gold rated supply from Corsair is still impressive for the price.Another benefit this PSU has is that it supports the new ATX 3.0 standard and comes with the new 12vhpc cable for when I need to upgrade my current GPU. The unit also comes with enough PCIe cables for any GPU requirement. Mine uses 3x cables. You get 6x cables total with 2x being able to daisy chain with but I don’t recommend you do that and instead use the 4x single 6/8pin cables instead.The unit fits nicely into my PC case without issue however my case is very large. It’s a cooler master cosmos s2 case. Had this awesome case for nearly a decade now.I am very happy with the build quality and the unit is extremely quiet with my PC under full load.I would highly recommend this power supply if your on a budget but you do need to make sure it will fit in your case first as cables are on the side of the unit.

The media could not be loaded. Overall it’s a great design, makes cables very accessible, however if you have a Corsair 4000D or similar cases it’s going to be hard to put all the cables away. Great addition however is that all cables are flat, makes a clean build.Very quiet PSU works like a charm. Had to swap out rm1000e due to bad coil whine, this one doesn’t have any which is great.

Wanted a 1200w for a moddern set up to manage new cpu mb and gpu with no effort.Very stable after having it for over 3 month's and its very quite to the point you cant hear it spin up the fan even under load.Comes with all cables necessary with the new 12 pin gpu power cable included. As for the temps. Its very cool even when pulling over 600w even 700 peaks with stable fan curves to match noise to performance values.Great item for the price and well worth it, highly recommend it to anyone seaking a robust psu.

I've been using the Corsair RM850x SHIFT for a few months now, and it's been nothing short of fantastic. The power delivery is rock-solid, ensuring my high-end components run smoothly without any hiccups. The build quality is top-notch, and the sleek design fits perfectly into my setup. The 'SHIFT' feature for real-time adjustments is a game-changer, allowing me to optimize power efficiency effortlessly. The cables are neatly organized and easy to manage, which is a huge plus for cable management enthusiasts. Overall, the RM850x SHIFT is reliable, efficient, and a definite recommendation for anyone seeking a high-performance power supply.

Good piece of kit. Plenty of connections and cables.

i had to return this as i had purchased the wrong PSU, Process was simple and easy. Based on the slightly higher wattage (same design) one i have now the PSU performs Beautifully and is very easy to install, Plenty of connectors to power my 4080 Super
