SILVERSTONE ST45F-ES230 450 80+ Bronze Non Modular Power Supply (450 W)

The SilverStone ST45F-ES230 (model SST-ST45F-ES230) is a 450W ATX form-factor power supply certified to the 80 Plus Bronze efficiency standard, delivering 82%–85% efficiency across 20% to 100% of its rated load. Designed for mainstream desktop builds that demand reliable, continuous power, it features a single +12V rail rated at 408W — channelling the majority of its output to the components that need it most, including discrete GPUs and modern multi-core processors. The combined +3.3V and +5V rail provides 100W, keeping headroom available for storage and peripheral loads. Active Power Factor Correction (PFC > 0.9 at full load) ensures stable operation across a wide input voltage range of 180–264 Vrms and a frequency range of 47–63 Hz, making it well-suited to regions with fluctuating mains quality, including India. Cooling is handled by a single 120mm silent fan with a minimum noise level of 18dBA, striking a practical balance between thermal management and acoustic comfort. The compact 140mm depth (150 mm W × 86 mm H × 140 mm D) eases installation even in mid-tower and some smaller ATX cases. Weighing just 1.29 kg, the unit is straightforward to handle during builds. The non-modular cable set includes one 24/20-pin motherboard connector, one 8/4-pin EPS/ATX 12V connector, two 8/6-pin PCIe connectors, six SATA connectors, and three 4-pin peripheral connectors — enough for most mid-range configurations without adapters. A black lead-free paint finish keeps the aesthetic clean inside windowed chassis. The ST45F-ES230 is compatible with ATX12V v2.4 and is protected by over-power, over-voltage, and short-circuit safeguards. SilverStone rates the mean time between failures (MTBF) at 100,000 hours, and the unit is covered by a three-year warranty. Operating temperature range is 0°C to 40°C, supporting continuous 24/7 duty within that envelope.
