ASRock Steel Legend SL-1200P 1200W - PSU, 80 Plus Platinum

The ASRock Steel Legend 1200W 80 PLUS Platinum ATX Power Supply is rated for 1200 W and intended for desktop gaming systems and workstations. Its Platinum certification indicates its power-conversion efficiency class. Compliance with ATX 3.1 and PCIe 5.1 matters when choosing a supply for components that use these standards. A native 12V-2x6 power connector provides a direct connection for graphics cards with the matching power input. Fully modular cabling lets builders attach only the leads their configuration requires, reducing unused cables inside the case.

The unit uses 100% Japanese capacitors, a stated detail of its internal construction. Cooling comes from a 135 mm striped axial fan with a fluid dynamic bearing. ASRock's iCOOL intelligent control manages the fan, and a silent mode is included. The ATX form factor matters for case compatibility, so the enclosure must accept an ATX power supply. These cooling and installation details distinguish the unit beyond its electrical rating, without providing a quantified noise level.
