The MSI MAG A850GL PCIe 5 is a great power supply for high end builds. Installation and cable management were easy thanks to the fully modular design and flat cables, and it keeps my system running smoothly with no power issues.

This MSI MAG A850GL power supply is an excellent choice. The build quality is solid, installation was straightforward, and the fully modular design with flat black cables makes cable management very clean and easy. It delivers stable power and runs quietly, even under load. The ATX 3.0 and PCIe 5.0 support is a big plus, making it ideal for modern and future GPUs without needing adapters. The 80 Plus Gold efficiency gives peace of mind, and the system stays cool and reliable during long gaming sessions. Overall, this is a high-quality, dependable PSU from MSI, and the 7-year warranty really seals the deal. Highly recommended for anyone building or upgrading a gaming PC.

First off, I love how it looks and fits perfectly in the case, with the matte black finish and flat cables which make the entire setup look clean and premium. The ability to not plug in what you wont use is pretty useful as it gives flexibility with smaller cases that don't have that much cable space in the back, so cable management was actually simple and not overwhelming. Performance wise, it’s a solid 10. My system powers up quickly and runs stable under load, no coil whine, no noise spikes, nothing. The 80 Plus Gold rating really shows as thermals stay cool and the fan barely spins up even during gaming sessions. The PCIe 5.0 connector is a nice bonus, even tho with a 5060 ti I won't be using it for now, but it future proofs the build for my next upgrade. Also like how all the cables come in a nice cute pouch bag thing, which just stores all the unused cables away and protects them from scratches. Overall, an excellent PSU, quiet, powerful, and looks great in the build. Would definitely recommend it for anyone doing a modern mid to high-end PC build.

What I love most about this power supply is its quiet operation and fully modular design. It made cable management incredibly easy, which not only improved airflow in my case but also gave my build a clean, professional look. It runs whisper-quiet even under load, which is a huge plus for me as someone who values a quiet setup for both work and gaming. I chose the MSI 850W over other brands because of its strong reputation, 80 Plus Gold efficiency, and compatibility with high-end GPUs. I was upgrading to a power-hungry graphics card and needed something dependable with headroom for future upgrades, and this fit the bill perfectly. The build quality feels premium, and the included cables are sturdy and well-labeled, which made installation stress-free. Overall, it gave me peace of mind knowing my system is powered by something stable and efficient. Highly recommend it for anyone building a mid-to-high-end rig.

I brought the A850GL after getting a new GPU and realising I needed more wattage. It is a great power supply, my PC no longer crashes under tasks and has made my system a lot more stable. I choose this one as it had the wattage I needed and was modular so it was easier to set-up. I was surprised at how quiet it was and it looks great! Pros: Great wattage Quiet Fully modular Cool under tasks Cables are very long Cons: Cables are a bit stiff and hard to work with

This PSU delivers solid build quality and fits perfectly in my mid-tower ATX case (Corsair FRAME 4000D). The cables came neatly organised in an accessory bag and are clearly labelled, which made setup easier. It powers my Radeon RX 9070 XT and Ryzen 7 9800X3D combo without a hitch. The unit runs quietly and has been reliable and efficient so far. My only gripe is the cables. They’re a bit stiff, which made cable management more of a chore than it needed to be. Overall, it’s a great PSU if you want something dependable and well-built.

When it finally arrived via 2 houses 2 streets and some good honest neighbours it was still in one piece. Nice solid unit with a huge guarantee period. I used the MSI main cable to connect with the board and plugged in the old EVGA cables already plugged into my mainboard. Nothing happened... I thought it was bricked, there is no indication this box is actually live, no little LED light, nothing at all. So I swapped out the old EVGA cables and plugged in the supplied MSI cables and it fired up instantly! Running fine now. So use the supplied cables! And beware of zero indication that this box is live, there is no LED and it does not hum, buzz, or make any noise at all even though it's a live unit.

This PSU is great because of its high wattage and its fully modular meaning is futureproof and its excellent for cable management. The cables that come with this PSU have the right length which makes cable management that much easier lastly the cable are very easy to connect to the intended slot since its ladled. Great Product I highly recommend!!

I recently purchased the MSI MPG A850GL power supply. While I haven’t fully assembled my new system yet, I can already say the PSU feels well-built and high quality. The packaging is solid, the unit itself has a clean design, and all the included cables are nicely sleeved and flexible, which makes cable management much easier. 850W is more than enough for modern mid- to high-end builds, and since it’s 80+ Gold certified, I expect it to be both power-efficient and stable. I’ve used MSI components before and they’ve always been reliable, so I’m confident this PSU will deliver the same level of performance once my build is complete. The only downside is that the shipping took longer than expected — the item was delayed in transit for a few days. Not a dealbreaker, but still a bit frustrating. Overall, very good product and definitely worth considering if you’re looking for a solid, efficient PSU for gaming or productivity builds.

La fuente de alimentación MSI MAG A850GL PCIe 5.0 es una excelente opción para equipos modernos de alto rendimiento. Es totalmente modular, lo que facilita la gestión de cables y es compatible con las GPU más recientes gracias a su conector PCIe 5 nativo. La calidad de construcción es sólida y la certificación 80 Plus Gold garantiza un bajo consumo de energía y calor. Funciona silenciosamente incluso bajo carga, y la garantía de 10 años ofrece tranquilidad. Una fuente de alimentación fiable y con garantía de futuro para gamers y creadores apasionados unque había visto comentarios de que era ruidosa, ahorita la armé con am5 un ryzen 5 7500F y una grafica provisional Rx6600, tal vez por eso no se nota que la fuente se esfuerza pero en un futuro voy a cambiar a una mejor gráfica más potente que aproveche el conector 12+4 pines de alimentación, lo único que no me gustó y que está incómodo de colocar es el conector de 24 pines para la motherboard, eso de que tengas que doblas el cable para colocarlo no me parece la mejor ingeniería, aunque claro, es funcional, y los cables se sienten muy resistentes, espero que duren mucho tiempo

Ottimo

Une très puissante alimentation et magnifique, je recommande pour de très grosse configuration mais pas pour des toutes petites car inutile si elle demande peut de puissance. En vous remerciant.

I recently installed the MSI MAG A850GL in my new gaming PC. The packaging was sturdy, and all necessary cables (including PCIe 5.0/5.1) were clearly labelled and easy to manage, thanks to the fully modular design. In day-to-day use, the PSU operates quietly. It supplies stable power to my RTX 5070 setup without the need for bulky adapters, making the overall experience cleaner. Efficiency is great with the 80 Plus Gold rating. The combination of modern compatibility, reliability, and ease of use makes this a strong value, especially for future upgrades. Highly recommended if you’re aiming to build a robust and clean gaming rig.
