Cooler Master V Platinum 3000 power supply review: Verified Platinum efficiency for workstations, with a stellar 12-year warranty
Built by Channel Well Technology, the V Platinum 3000 Workstation delivers 3000W through four native 12V-2x6 connectors with excellent regulation, low ripple, and a twelve-year warranty. Efficiency clears 80 PLUS Platinum at 230 VAC, if narrowly at the top of the curve. It runs hot and loud above half load, has no fanless mode, and accepts 220-240 VAC only. Pricing is not yet announced.

Cooler Master occupies an unusual position in the power supply market. Founded in Taiwan in 1992 and best known for the cases and coolers that made its name, the company has spent more than two decades selling PSUs without ever being a PSU manufacturer in the strict sense. Like most brands in this space, it commissions platforms from a rotating cast of OEMs, and the quality of a given Cooler Master unit has historically tracked the quality of whoever built it. The V series sits at the top of that catalog, and it is the line where Cooler Master has consistently spent money on the platform rather than on the sticker.
The V Platinum 3000 Workstation is something else again. Announced at the end of July 2026, it is Cooler Master's entry into the multi-kilowatt category that SilverStone opened with the Hela 3000RZ, and Thermaltake followed with the AX-3200, aimed squarely at multi-GPU AI development boxes and rendering workstations rather than at anything that could reasonably be called a home and/or gaming PC. The headline numbers are a single 12V rail rated at 250A, four native 12V-2x6 connectors, twelve PCIe 6+2 connectors, twelve SATA and four Molex, all fed from a 202 mm chassis with a twelve-year warranty behind it. The catch is on the input side: this unit accepts 220-240 VAC only, drawing up to 16A through an IEC C20 inlet, and it shuts down when the AC line drops below roughly 170 VAC. There is no 115 VAC operating mode, which is why every measurement in this review was taken at 230 VAC. We await the pricing announcement to ascertain where the V Platinum 3000 Workstation ranks among our list of best power supplies today.
The V Platinum 3000 Workstation ships in a plain kraft carton wrapped in a deep blue sleeve, with a render of the unit on the front and the badges laid out along the bottom edge: 80 PLUS Platinum (230V EU), the twelve-year warranty shield, a Japanese capacitor callout, and the ATX 3.1 with 12V-2x6 and PCIe 5.1 Ready logos. It is a restrained, business-like presentation, and appropriately so. Nobody buying a 3000W workstation supply rates shelf appeal as top priority. We should note that the 80 PLUS certification is not published on CLEAResult’s public database at the time of this review.
Inside, the supply sits between molded protective packaging. The accessory bundle is spartan: a multilingual user guide with the pin-layout diagrams, Cooler Master's recommended PCIe cable installation leaflet, and four mounting screws. There are no cable combs, no zip ties, no Velcro straps, and no storage pouch. For a unit that ships with more than thirty individual connectors, the absence of any cable management hardware is a genuine omission rather than a cost saving, and it is one of the few places where the presentation feels thinner than the product. Most importantly, however, there is no AC power cable, and this unit requires a C19 connector, which is not very common.
The modular cables are very flexible, all-black and per-wire mesh-sleeved rather than the flat ribbon types Cooler Master uses further down the range, which suits the intended market. These will be routed once, most likely in a large chassis, and left alone. The four 12V-2x6 cables use the two-color connector treatment the ATX 3.1 specification encourages, with purple latch inserts that make an incompletely seated plug immediately obvious visually.
