MSI MPG A850G PCIE5 Power Supply Unit, UK Plug - 850W, 80 Plus Gold Certified, Fully Modular ATX 3.0, PCIe 5.0 GPU Support, Japanese 105°C Capacitors, 0% RPM Mode, Flat Cables - 10 Year Warranty

I was very relieved when i received this item. I had had to return a motherboard AND ram as i was building this computer so for a start, the fact that this works as intended is brilliant. It has a low-noise option which i make use of and a very good power efficiency, slightly above the 80plus rating, not that that matters a lot. The box is lovely, glossy printing and thick cardboard, which is a great bonus and helps it feel like a premium product. It has 2 cpu power cables and 3 PCIE ones which is more than a few others around this price point. The 12vHPWR, though not in use by me, has a yellow connector at both ends to make sure you plug it in fully and don't explode your lovely NVIDIA gpu. I will add that pcie 3.1 standard apparently doesn't have such issues, but as a 3.0 product it's a good way to alleviate it. Will rate 5 stars, no issues whatsoever unlike other products from ASUS AND CORSAIR AHEM... Anyway 5/5 does what it says on the tin and with great style, efficiency and price if you get it for £100-110

I got this PSU because MSI is a brand I trust. I’ve used MSI parts for around 20 years and they have never let me down. I find the build quality is always great and well packaged so the items get to you un-damaged. Pros Great cable quality and everything you need for your builds. Silent switch on the PSU so if your PC is idle and the PSU is cool the fan will switch off. Nice design on the side of the PSU so if you have a case where you can see the PSU then you are not just looking at a black box. A choice of 12v GPU cables. Cons The SATA power cables are a bit too long for my build so I did have to tuck them in a bit more than I would have liked. Over all this PSU has been a great addition to my all MSI build and will deliver the power I need to run my PC and give me some headroom if I want to add more drives, upgrade my GPU or over clock my system. At £109.99 I personally feel it’s an amazing price and with a 10 year warranty over the 7 year you get with the MAG PSU for an extra £10 I feel it’s a no brainer

I recently purchased the MSI MPG A850G PCIE5, and I couldn't be happier with my choice. This PSU delivers excellent performance while remaining whisper-quiet thanks to its silent mode. The fully modular design makes cable management effortless, ensuring a clean and tidy setup. One of its standout features is ATX 3.1 compatibility, future-proofing my build for upcoming hardware needs. The overall build quality feels premium, and installation was straightforward.

The MSI MPG A850G has been solid so far. It’s easy to work with thanks to the fully modular cables, and it comes with a small bag for the cables you don't use. There’s a 0-fan mode toggle next to the power switch. However, I use it with the fan on, but the PSU is still silent in my setup. It runs quietly under load, and I haven’t had any issues. The size is also pretty good, slightly smaller than my previous PSU. It has the same high-quality parts as a more expensive PSU, but for a way better price. Would recommend.

Right away, I was impressed by how well this PSU fits in my case. The matte black finish and flat modular cables make the setup look very tidy and professional. Being able to connect only the cables you actually need is a great touch—it keeps things neat, especially in smaller cases where space is limited. Cable management was super easy and didn’t feel like a chore at all. In terms of performance, it’s flawless. My PC boots fast and stays rock-solid under heavy load—no coil whine, no odd noises, nothing. The 80 Plus Gold certification really holds up, with cool temps and a fan that rarely spins up, even during gaming. The PCIe 5.0 connector is a nice addition too. I also appreciate the small details—like the included pouch for storing extra cables, which keeps everything organized and protected from scratches. Overall, this PSU is an excellent choice: quiet, efficient, powerful, and stylish. I’d absolutely recommend it to anyone building a modern mid- to high-end PC setup.

Chose this ATX 3.0 PSU as it seemed the best bang for buck at the time, upgrading from an older corsair 550w due to a new GPU. A modern PSU and being 850w should last well into the future. Fully modular so cable management made easy and the cables seem really good quaility. Runs very quiet and efficient, there is a physical button at the back to keep the fan off under low load. It comes with the new 12v power supply needed for 40xx GPU so this was also a plus making cable management tidier and no doubt this will be the standard moving forward. Plenty of cables included in the box and it also comes with a nice branded storage bag to keep them in. The nice thing about a quality PSU is that you can move it into your new builds in the future and with a long 10 year warranty and Japanese capacitors I'm confident this will serve me very well for may years to come. Recommended.
