SILVERSTONE ST50F ES230 500W Non Modular ATX 2.0 Power Supply

The SilverStone ST50F-ES230 is a 500W non-modular ATX power supply designed for desktop PC builds that demand stable, efficient power delivery in a compact form factor. Built to the ATX 2.0 standard and compatible with ATX12V v2.4, it integrates smoothly with a wide range of modern motherboards and GPU configurations. At the heart of the ST50F-ES230 is a single +12V rail rated at 456W, ensuring steady, undivided current delivery to power-hungry components such as discrete graphics cards and multi-core processors. The unit carries an 80 PLUS certification, achieving 82–85% efficiency across 20–100% load, which reduces wasted heat and keeps running costs in check. Active Power Factor Correction (Active PFC, PF >0.9 at full load) further improves power quality and compatibility with UPS systems. Thermal management is handled by a 120mm fan with a minimum noise level of 18 dBA, allowing the PSU to operate without becoming a noticeable source of noise in most PC environments. The operating temperature range spans 0°C to 40°C, supporting continuous 24/7 use under standard room conditions. The cable harness is non-modular and includes all connectors required for a typical mid-range build: one 24/20-pin motherboard connector, one 8/4-pin EPS/ATX 12V connector, two 8/6-pin PCIe connectors (for dual-GPU or single high-end GPU setups), four SATA connectors across two cable runs, three 4-pin peripheral connectors, and one 4-pin floppy connector. This breadth of connectivity makes the ST50F-ES230 a capable choice for budget and mainstream system integrations. Protection circuitry covers over-power protection (OPP), over-voltage protection (OVP), and short-circuit protection (SCP), helping safeguard connected components against common electrical faults.
