Thanks to the SFX format, the SilverStone SST-SX450-B is primarily designed for mini cases (mostly in Mini-ITX format) and offers high performance in minimal dimensions. It comes with a quiet 80-millimeter fan with an optimized fan curve. This makes the SST-SX450-B a great solution for nearly all users who want to combine high performance with low noise.

The power on the 12-volt rail, which is crucial for graphics cards, delivers a full 450 watts (37.5 amps), providing ample power. With overload protection, undervoltage protection, overcurrent protection, overvoltage protection, and short-circuit protection, essential safety features are included. Instead of a split 12V rail, this version features a very robust single rail, making it suitable even for multi-GPU systems.

In total, there are two PCIe 6+2-pin connectors available. Additionally, there are a 20+4-pin, a 4+4-pin, three SATA, two 4-pin Molex, and one floppy connector for the motherboard and peripherals. The SST-SX450-B also excels in efficiency, achieving an efficiency rating of up to 85 percent, which is why it has been awarded an 80 PLUS Bronze certification.
