Power for everyday builds

The SilverStone SST-ST50F-ES230 is a 500W ATX12V power supply built for standard desktop systems. It delivers continuous output at 40°C and carries 80 PLUS certification for 82% to 85% efficiency across typical loads. The single +12V rail provides 34A for stable component power. Active PFC and multiple protection circuits guard against voltage irregularities.

Fixed cables and silent cooling

A 120mm fan rated at 18dBA handles thermal management with low noise. The non-modular loom includes a 24Pin motherboard connector, 8Pin EPS12V and 4Pin ATX12V for CPU power, two 8/6Pin PCIe connectors, six SATA plugs, three 4Pin peripheral leads and one floppy connector. Cable lengths range from 150mm to 700mm to reach most chassis layouts. Input voltage spans 207V to 253V at 47 to 63Hz.

500W single-rail capacity

The 500W rating on a single +12V rail with 34A determines whether this unit fits your graphics card and CPU combination. Builds requiring more than two PCIe power connections or higher total wattage should look elsewhere. MTBF is rated at 100,000 hours for long-term reliability. Dimensions are 3.39in by 5.91in by 5.51in for standard ATX mounting.
