A 1000W fully modular ATX 3.1 power supply upgraded to Cybenetics Platinum efficiency and bundled with CORSAIR's ThermalProtect PCIe 5.1 600W 12V-2x6 cable, which monitors GPU connector temperature and cuts power at 65°C to prevent cable and card damage. Offered in black and white.
AI score breakdown
scored as defaultIts biggest strength is the feature set: full ATX 3.1/PCIe 5.1 compliance, native 12V-2x6, Zero RPM operation, and the standout passive ThermalProtect cable whose in-cable OTP directly targets the industry's 12VHPWR/12V-2x6 melting-connector problem without needing any software or special GPU. The biggest weakness is value at the $179.99 MSRP, since the near-identical 2025 model streets far cheaper and its real efficiency lands at Cybenetics Platinum/80Plus Gold territory rather than true Platinum, so much of the premium is paid for the bundled safety cable rather than raw performance gains.
