Hardware Secrets Silver Award

Introduction

SilverStone offers two SFX12V power supplies, the ST45SF, which comes with the 80 Plus Bronze certification, and the ST45SF-G, which comes with the 80 Plus Gold certification. Both are rated at 450 W. Let’s see if the ST45SF-G is a good pick.

The SilverStone ST45SF-G is only 3.9” (100 mm) deep, using a slim 80 mm ball-bearing fan on its bottom (Young Lin Tech DFB801512H).

The cabling system is fully modular, meaning that even the main motherboard cable is detachable. This system has five connectors: one for the main motherboard cable, one for the ATX12V/EPS12V cable, one for the video card cable (blue connector), and two for SATA and peripheral cables. This power supply comes with the following cables:

  • Main motherboard cable with a 20/24-pin connector, 12.6” (32 cm) long
  • One cable with two ATX12V connectors that together form an EPS12V connector, 16.5” (42 cm) long
  • One cable with one six-pin connector and one six/eight-pin connector for video cards, 16.5” (42 cm) to the first connector, 5.9” (15 cm) between connectors
  • One cable with three SATA power connectors, 12.6” (32 cm) to the first connector, 7.9” (20 cm) between the first two connectors and 5.9” (15 cm) between the second and third connectors
  • One cable with two standard peripheral power connectors and one floppy disk drive power connector, 12.6” (32 cm) to the first connector, 7.9” (20 cm) between connectors

All other wires are 18 AWG, which is the correct gauge to be used.

The number of connectors is perfect for a 450 W power supply. In fact, it comes with two connectors for video cards, a feature not usually found on power supplies below 500 W.
