Cooler Master V850 White SFX Gold ITX SFF Modular Power Supply, 850W 80Plus Gold, ATX 3.1 | 90° | PCIe 5.1, Designed Ready Nvidia RTX 5080 | AMD RX 9070 XT, Customized Cable, 100mm|3.9", 10-Year

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.

Purchased this SFX power supply for my Ncase M2 build. So far a few months in, it has performed very well staying quiet even under full load with a 9800X3D and a 9070 XT. Being that it is modular you can choose which cables to use, allowing for reduced clutter in an SFF case. Overall it’s a great little power supply!

This PSU has been solid in my SFF build. Installation was straightforward, cables are flexible enough for tight cases, and overall stability has been good. Power delivery has been consistent, and I haven’t experienced any issues so far. It’s not flashy, but it gets the job done and fits well in a compact setup. A dependable option if you need an SFX PSU with modern ATX 3.1 support.

The good: Easy install. Soft cables. Powerful and tiny. Not expensive considering I bought a 650 watt sfx for $133 a few months ago. The Bad: The fan is fairly loud. It seems to be running constantly. For the price I really don't mind upgrading to a noctua fan and connecting it to to my fan hub. I can set a curve for it following the amount of electricity being used. Great purchase, but wouldn't mind if they had an upgraded fan version, and it's probably to much to ask for a fan bypass connection to connect it to an external source.

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.

Update: The replacement that Im using, now my third which I bought from amazon, is giving random shut downs and reboots. DONT BUY THIS PSU OR BETTER PUT POS!!!! Im not one to write these types of reviews but as a part-time builder/side hustle cooler master has the worst and I mean THE WORST customer support. Ive had 3 of these fail. Luckily amazon took one of them back and the other one failed after 6 months. The third one I just gave up on and bought something else. Im not here to promote another company but when you build a lot of PCs sometimes parts fail. It happens. The measure of a company is how they handle it. Razer takes months to RMA something while the major brands are usually pretty good but cooler master still has my PSU that was 3 months old and died. No one replys to emails, or support tickets, NO ONE picks up the phone, their online chat is also never answered, facebook goes unanswered, twitter etc. Corsair will RMA you part in a few weeks. Silverstone same thing but cooler master doesnt care at all. I will never use their parts even if it free. Even if it's a heatsink. This is no way to treat loyal customers.

Well made

Excellent PSU. And even better for me – white color + a single cable for the GPU 12VHPWR PCIe 5.1 connector (instead of 3 cables to a 12VHPWR adapter).
