The MSI MAG A550BN is a solid and reliable power supply. Installation was straightforward, and it provides stable power with no issues so far. It’s been running quietly, even under load, which is a big plus. The build quality feels good for the price, and the cables are decent quality and long enough for a standard mid-tower case. At 550W, it’s more than sufficient for a typical gaming or everyday PC build. Overall, this is a dependable and affordable power supply from a trusted brand. Ideal for budget or mid-range systems, and I’d happily recommend it.

Fantastic PSU, arrived today (delayed by Amazon despite Paying for next day) very easy to Install despite missing Instruction lol thankfully its basically idiot proof anyway if you know what your doing. Super quiet, very fast to install absolute dream. Might need to step it up to a 750w once I've built my new PC in a couple of months depending on the power drain of the new GPU I buy for it and if I need to I will deffo be buying the 750w version too. Cables are all provided and easy to connect to both the PSU itself and the Motherboard. Packaged really well so no damage. Looks really nice, not that I can see it now its installed but still and very sturdy design. 80+ Gold Rated so should help keep the energy costs down and powers everything in my current build perfectly. What more can I say? Top piece of kit well worth the cost vs a cheaper PSU.

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.

This looks to be a quality all white modular PSU at a reasonable price. I've not had the full system running fully yet but in testing the PSU seems of similar quality to the Corsair TM it is replacing in my new build. I love the all white aesthetic which was the primary reason for we choosing this unit over other options. The PSU ticks all the right boxes on paper, it is 80+ Gold, fully modular and supports PCI 5.0. For the price it is fantastic value and the MSI warranty is always sufficient although in my experience I have never needed to claim after 20 years or using their stuff. The PSU seems well build and sturdy no sign of rattling and the flat white cables are fantastic to work with for clean cable management. Overall it is early days but I am confident this will be a long lasting PSU, it ticks all the boxes and I can recommend.

MSI MAG A850GL is a premium feeling PSU for less money that the big manufacturers. The unboxing experience was made it feel like you were buying a much more expensive product. The PSU itself was safely contained in think soft foam. Next to the PSU was the bag of modular cables. My PSU came a good selection of cables. All the normal cables you'd expect and the 12VHPWR . Most cables were 'flat', making it easy to route and hide in my PC case. Weirdly the 12VHPWR was braided but instead of individual cables, it was the entire bunch of cables done as one. A weird choice if you ask me as it kinda looks odd compared the other cables. The cable length great, I did not have any issues with cables being too short or too long for my build. The PSU has a platinum cybernetics rating at 230V for power and a standard + for sound. The PSU does not appear to be loud, but time will tell. Currently the PSU if quite enough that I cannot hear it over the other fans in my PC. If I had to change anything, I'd like to see MSI remove the braiding from the 12VHPWR (keep everything consistent) and change the last SATA power connector to be flat, not a right-angle connector. Overall, I can definitely recommend this PSU.

This is a great power supply and does exactly what is needed. It's a very sturdy metal construction which has a nice visual design. It comes with a large array of cables for all the different types of components. As this was my first build I had to Google where all the cables went. It came with around 11 cables but you DO NOT need to use every cable that comes with the supply. I only needed 4 (Motherboard power cable, the 600w 16 pin GPU cable, 1 CPU/PCIe cable, and 1 SATA cable (and of course the main power cable to the mains electric)). It's really quiet. I have 10 fans (11 with the PSU) and it's all really quiet when running. I've played Battlefield 6 and it seems to handle everything well with no issues. At 1000w it's more than enough for my 600w system, so gives plenty of future room for upgrades. Overall a great power supply and I would definitely recommend it! (Excuse the messy wiring... it was before cable management).

Recently upgraded my system and went with the MSI MAG A850GL PCIE5, and I’ve been really impressed so far. Build quality feels excellent, the unit is solid and well-finished, and the flat black modular cables make cable management much easier and cleaner. The ATX 3.0 / PCIe 5.0 support was a big selling point for me, especially with newer, more power-hungry GPUs. It’s been completely stable under load, with no coil whine or strange noises, and it runs nice and quiet even during gaming or rendering sessions. Efficiency-wise, the 80 Plus Gold rating does exactly what you’d expect, and the fully modular design means you only use the cables you actually need. Installation was straightforward, and everything feels well thought out. The 7-year warranty is also reassuring and shows confidence in the product. Overall, this feels like a reliable, future-proof PSU from a trusted brand, and I’d happily recommend it if you’re building or upgrading a modern PC. Great value for money and peace of mind.

I picked up the MSI MAG A1000GLS PCIe 5.0 to round out a new build, and honestly? I’m blown away. It’s quiet as a whisper and powers my MSI GPU like an absolute dream. Even under load, the whole system feels calmer — like the PSU is sitting there meditating while my GPU sprints a marathon. Performance: This unit doesn’t flinch. Frame spikes? Heavy renders? Torture tests? The A1000GLS dishes out clean, stable power like it’s bored. And having native PCIe 5.0 ATX 3.0 support just future-proofs the whole rig. No sketchy adapters, no spaghetti cables. Noise & Thermal: The fan curve is chef’s kiss. For the most part, I can’t even hear it over my case fans. When it finally spins up, it’s a soft woosh — not the haunted-vacuum-cleaner energy some PSUs bring. Build Quality: Feels premium in the hands, looks clean in the case, and the fully modular cables make routing ridiculously tidy. MSI clearly didn’t cut corners. Price: For a 1000W, PCIe5-ready, ATX 3.0-certified unit with this level of build quality? Very competitively priced. Especially considering what other brands are charging for similar features. Verdict: If you want a PSU that’s reliable, quiet, future-proof, and won’t make your wallet combust — get this one. The MSI MAG A1000GLS doesn’t just power your system… it COOKS.
