Works as advertised and super quiet.
Works exactly as advertised. I bought it for an ITX case that didn't have one. The PSU I already had did not work with it, plus mismatched cables made operating impossible. Super-quiet, not all that difficult to install into the target case. All in all, I'm very satisfied with it.

Works well.
It's well made and it is extremely quiet on low loads but can get a little louder as it ramps up, but 90 % of the time it's very quiet. I love the cables it came with. They where the perfect size for the case I was using so it made cable management a breeze.
W**!
Tiny powerful power unit
Very impressed because I put this unit in my fractal Terra. Ensure if you’re building a fractal Terra, you attach the wires first and then put the unit inside of the fractal terra. Very quiet and does the job excellently definitely recommend.

What a great PSU for its size
This is my first purchase of a SFF power supply.I've always purchased from Corsair or EVGA but I saw good reviews for Cooler Master and I've purchased their products before. I was building a SFF PC and needed a PSU to fit in it. This was priced reasonably for 850w. It has been working great with no issues. It's incredible how small these have gotten. The modularity is great as I don't need to use every cable, which made the build much easier.

Decent but overpriced in my opinion as most Form factor parts are.
The Cooler Master V850 SFX Gold packs a serious punch in a miniature package, but is it the perfect PSU for your mini-ITX build? Let's dive in: Powerhouse in a Pint-Sized Package: 850W of juice makes it suitable for even the most power-hungry builds, from high-end CPUs to RTX 3080s. 80+ Gold efficiency keeps energy waste and your electricity bill in check. Compact SFX form factor fits snugly in mini-ITX cases, leaving room for your other components to shine. Whisper-Quiet Cooling: (mostly) FDB fan spins silently under normal loads, keeping your rig a tranquil oasis. Even under heavy pressure, noise levels stay surprisingly low, although some users report a noticeable hum. Modular Magic: ✨ Fully modular cables let you ditch the clutter and keep your case looking sleek and tidy. High-quality braided cables are durable and flexible, making installation a breeze. A Few Snags to Consider: Price tag reflects the premium performance and compact size, making it pricier than some non-SFX options. The included SFX-to-ATX bracket might be unnecessary for some mini-ITX cases and adds extra bulk. A couple of user reports mention coil whine under specific workloads, though not a widespread issue. Verdict: The Cooler Master V850 SFX Gold is a top contender for mini-ITX builders seeking top-tier power and quiet operation. Its compact size, high efficiency, and modular cables make it a dream for building clean and cool rigs. However, the premium price tag and potential for minor noise quirks might give budget-conscious or noise-sensitive users pause. In short: Get it if: You want the best power delivery and efficiency for your mini-ITX build, prioritize low noise, and appreciate quality craftsmanship. Skip it if: You're on a tight budget, can tolerate a bit more noise, or don't need the absolute power-house performance for your setup.

Knock on wood, works great after 3 years of POWERRR
Powering my 5950X and 3070 in the CM NR200 for the last 3 years no complains great cables great power after a lot of power shut downs over the years, the fan seems quiet like the day I installed it.

Does not come with all cables.
3 PCI slots but only comes with 2 cables, do not buy if using high end graphics cards. In fact, if you're not using your grandpa's old GPU then it's a safer bet to go a different route, might be a chance you get the cables you need. Update: Also the logic of selling a psu that obviously has a near 100% chance of going into a mini-itx form factor case, along with the stiffest ribbon cables I've ever seen (with pigtails instead of the actual number of cables that it should come with, i.e. previous issue with this psu) is hilarious. Aside from being stubbornly stiff and difficult to route, the pigtails are either useless and in the way, adding unnecessary material, or difficult to use and in the way. Luckily there's cages over my aio fans otherwise there would be absolutely no way to keep the pigtails from going into the fan blade. Added bonus is I'm using an NR200P, which is THEIR CASE! I'm shocked so little thought went into the compatibility of two products, made by the same company, that are highly likely to be paired together.

Its a reasonably priced SFF PSU
Super stiff cable cords, but otherwise seems solid. I haven't owned it long term, so I don't know the reliability. (I'll post back if something goes wrong though.) If you have the space, get cable extenders (which are MUCH easier to work with) and the stiff cables won't be a problem. I can't hear any noise over my case fans, so it seems quiet enough in that regard. SFF "tax" makes me sad and I wish I could have gotten it a better sale price (only $10 off).

Short PCIE cables and UK power cord can’t be plugged into the wall
Received today the item and started to mount it on my pc, however the PCIE cables are really short, also the power cord head is way too small to be able and plug it into the socket. No ideea why.

Great psu for sff builds
I got this psu as part of a small form factor build - Aorus B550i, Ryzen 5 5600x, Sapphire Nitro 6700xt, Corsair 32GB RAM, and Sabrent 2TB (PCIE4) and Corsair 2TB (PCIE3) M2 drives, and a Noctua L9a cooler. This all fit into a Fractal Terra case and the PSU provides stable, clean power to all the components. The PSU itself is easy to mount, compact, and has clearly labelled connectors that tell you which end plugs into the PSU and which end plugs into your component. The labeling on the PSU case is also clear to minimize errors when you plug things in. The cable lengths are a bit long for a Fractal Terra. (if you're building in a mATX case, they should be fine). But for my build, I had to really compress the cables and tie them down to the spine to allow the Terra side panels to close. If possible, I would like to see shorter cable length options available when you purchase the PSU or have shorter cables included. I'd pay a bit more money to have that option for a cleaner look (and less stress on the cable). I don't expect too any issues with power load as my system will not be overclocked and at full draw on the CPU and GPU, should only be around 40-45% of the PSU max wattage.
