ASRock will launch two Steel Legend power supply units on September 19, 2025, delivering 1,200W capacity for demanding systems. The SL-1200G model costs $223 in black finish, while the SL-1200GW variant carries a $229 price tag in white. Both units achieve 80 PLUS GOLD certification and earn Cybenetics PLATINUM efficiency ratings alongside LAMBDA A noise standards. The power supplies support ATX 3.1 and PCIe 5.1 specifications for modern hardware compatibility. Dual 12V-2x6 connectors provide direct power connections for high-performance graphics cards.
A 135mm fluid dynamic bearing fan with a specialized blade design manages thermal performance through intelligent control systems. The iCOOL technology automatically stops fan operation during low-power scenarios to maintain silent operation. Japanese capacitors enhance long-term durability while protective circuits guard against electrical faults and overheating conditions. Standard ATX dimensions of 150 by 150 by 86 millimeters ensure broad case compatibility. The manufacturer provides 100,000-hour mean time between failures ratings and backs each unit with a decade-long warranty coverage.
