Its verdict calls the unit a showpiece with excellent efficiency, tight regulation and low ripple, and notes that the fanless window covers half of its rated output at room temperature (Tom’s Hardware). Against that, the review lists Taiwanese capacitors, a noisy hot run and a 200 mm long chassis (Tom’s Hardware). The company’s product page currently lists the unit at $339.99 (Corsair (official statement)).

Details (as Reported)
Corsair describes a built-in PinProtect+ that monitors current across each 12V pin on the 12V-2x6 connection and limits GPU power if excessive current persists (Corsair (official statement)). Alongside it, the company lists an integrated iCUE LINK System Hub that connects up to 24 iCUE LINK devices, and a 140mm Magnetic Dome bearing fan with a zero RPM mode (Corsair (official statement)). Steady output reaches up to 91% efficiency, and the fan ramps up automatically under heavy loads (Corsair (official statement)). The page also notes that 30mm of clearance between the power supply and the side panel is required (Corsair (official statement)).
Tom’s Hardware reports that the unit is built by CWT, was first shown at Computex 2026, and is rated to deliver its full output continuously at ambient temperatures up to 50°C (Tom’s Hardware). At 150 x 86 x 200 mm, the unit has clear polycarbonate panels on three sides (Tom’s Hardware). Among its reasons to buy, the reviewer lists Cybenetics Platinum certification, tight voltage regulation, low ripple, fanless operation up to 500W, per-pin 12V-2x6 protection and the ten-year warranty (Tom’s Hardware). The bundle contains the AC power cord, four mounting screws, black cable ties and a safety leaflet, which the reviewer calls spartan for the class (Tom’s Hardware). Cables include a native 12V-2x6 cable rated for 600W, eight SATA connectors and eight Molex connectors (Tom’s Hardware).
