SilverStone SFX ST45SF-G 450W
SilverStone also provided a second version of the ST45SF, and it's a bit different. It has an 80 Plus Gold certification, which is unique for SFX PSUs. It has a single 12V rail, but has a higher maximum of 37A.
The power supply has the same number of connectors as its sibling, but it's modular and the cables are sleeved. It features an 8cm fan. The price is also higher at £93.
