ASRock Steel Legend SL-1000P 1000W - PSU, 80 Plus Platinum

The ASRock Steel Legend 1000W 80 PLUS Platinum Fully Modular ATX 3.1 Power Supply provides power for desktop PCs, including gaming systems and workstations. Its efficiency certification indicates high power-conversion efficiency, though no specific percentage is supplied. Fully modular cabling allows builders to connect only the cables required by their components, reducing unused wiring inside the case. Compatibility covers ATX 3.1 and PCIe 5.1 systems. A native 12V-2x6 connector with TempGuard technology provides a connection for graphics cards using this power interface.

Cooling is handled by a single 135 mm fan. Silent-mode operation is available, although the conditions under which it activates are not specified. The listed noise level is 20 dB, with no accompanying load or measurement conditions provided. Internal components include Japanese capacitors rated for 105 °C, a relevant construction detail for a power supply exposed to heat during operation. ASRock specifies a mean time between failures of 100,000 hours, which is a reliability metric rather than a guaranteed operating lifespan.
