SFX 450 W power supply
The Silverstone SST-ST45SF-V3 delivers 450 W of continuous power in the standard SFX form factor. An included bracket allows installation in ATX cases. It is built for small-form-factor systems that need reliable 24/7 operation at up to 40 ambient temperature.
80 PLUS Bronze single +12 V rail
The unit carries 80 PLUS Bronze certification with 82 to 85 percent efficiency across 20 to 100 percent load. A single +12 V rail supplies up to 36 A, simplifying power distribution for the CPU and graphics card. Active PFC and a wide 90 to 264 V input range ensure stable operation worldwide.
Compact 100 mm depth with essential connectors
At 100 mm long the supply fits tight SFX chassis while the 92 mm silent fan keeps noise low. Cabling includes one 24/20-pin motherboard connector, one 8/4-pin EPS connector, one 8/6-pin and one 6-pin PCIe connector, three SATA connectors, two peripheral connectors and a floppy connector. Over-voltage protection and a 100000-hour MTBF rating back long-term reliability.

この商品に関する質問
Will the 450 W continuous rating hold up inside a compact case running at 40 °C?
Yes, the unit is rated for 450 W continuous output at 40 °C ambient, so it delivers full power even in warm small-form-factor builds.
What does the 80 PLUS Bronze badge actually limit in daily use?
It guarantees 82 % to 85 % efficiency from 20 % to 100 % load, meaning less waste heat and lower electricity draw across typical workloads.
Does the 100 mm length and included bracket let me mount it in a standard ATX chassis?
The 100 mm SFX body fits SFX slots natively, and the supplied bracket adapts it to ATX mounting holes without modification.
