Cooler Master's 3000W Platinum arrives with no price, no cord, and no 115 VAC mode

Cooler Master announced the V Platinum 3000 Workstation at the end of July 2026, a 3000W unit built by Channel Well Technology with four native 12V-2x6 connectors and a twelve-year warranty ^[6][7]. The specification that decides who can buy it is on the input side: 220-240 VAC only, drawing up to 16A through an IEC C20 inlet, with a shutdown when the AC line drops below roughly 170 VAC and no 115 VAC operating mode at all ^[1].

That is not a footnote. A supply whose undervoltage cutoff sits at about 170 VAC cannot start on nominal 100-127 VAC mains, so a North American buildout needs either a 208-240 V circuit run to the bench or a different power supply ^[4]. Tom's Hardware took every measurement at 230 VAC for exactly this reason ^[12].

The rest of the sheet is what the category has settled on. A single 12V rail is rated at 250A ^[9], which is 3000W, meaning the entire nameplate output lives on that one rail ^[21]. Alongside the four 12V-2x6 cables there are twelve PCIe 6+2, twelve SATA and four Molex connectors ^[10]. Cooler Master is following SilverStone's Hela 3000RZ and Thermaltake's AX-3200 into a segment aimed at multi-GPU AI development boxes and rendering workstations rather than gaming PCs ^[16].

Engineering-wise the reviewer found excellent load regulation, low ripple throughout, an all-Japanese capacitor complement, generous minor-rail OCP and a conformal-coated PCB ^[17]. Efficiency clears 80 PLUS Platinum at 230 VAC, though narrowly at the top of the curve ^[12]. Against that, there is no fanless mode, it is loud above half load, and the review records extreme hot-box temperatures ^[14]. The chassis measures 202 x 150 x 86 mm, and that depth rules out a great many mid-tower cases outright ^[5].

Two omissions are operationally annoying. First, the unit ships with more than thirty individual connectors and no cable combs, ties, straps or pouch; the bundle is a multilingual guide, a PCIe cable installation leaflet and four mounting screws ^[11]. The cables themselves are flexible, all-black and per-wire mesh-sleeved, with purple latch inserts on the 12V-2x6 plugs that make an incompletely seated connector visible ^[20]. Second, there is no AC power cable in the box, and the unit requires a C19 connector, which is not very common ^[3]. Anyone ordering this is also ordering a 16A-rated C19 cord separately, and should price that in before the PSU arrives ^[13].

Then there is paperwork. The sleeve carries an 80 PLUS Platinum (230V EU) badge, a twelve-year warranty shield, a Japanese capacitor callout and ATX 3.1 with 12V-2x6 and PCIe 5.1 Ready logos ^[15]. But Tom's Hardware reports that the 80 PLUS certification is not published on CLEAResult's public database at the time of the review, and lists "no certifications at the time of review" as a con ^[2]. So the packaging asserts a rating a purchaser cannot currently verify from the certifying body's own records ^[8]. For procurement teams that require certification evidence in a purchase order, that is a blocker regardless of how the unit measures on a bench.

Pricing has not been announced ^[18]. Cooler Master, founded in Taiwan in 1992 and best known for cases and coolers, commissions its platforms from outside OEMs rather than building them, so the CWT provenance here matters more than the badge on the front ^[19].

Watch for three things: the price, a CLEAResult listing that matches the box art, and whether Cooler Master follows with a wide-input or 115 VAC-capable variant. Until the third happens, this is a supply for 230 V regions and for North American shops that already run 208-240 V drops to the rack.
