Silverstone SST-SX550 550W PSU Review

AS7V6150

The SilverStone SST-SX550 is a diminutive SFX power supply measuring 125 mm (W) x 63.5 mm (H) x 100 mm (D). It weighs only 1.1kg. The paintwork is quite good and proves fairly resistant to scratching. This is a non modular power supply so all the cables are hardwired into the chassis. Call me old fashioned, but I would have preferred if SilverStone had sleeved the cables all the way into the chassis, rather than stopping short. It does look a bit naff.

The small fan grill is clearly seen on one side of the power supply, shown above. Strangely there is no SilverStone badge in the center position, like we would normally expect to see.

One side of the power supply is vented to support airflow. There is a power connector and switch close by.

The Silverstone SST-SX550 delivers a very capable 45A via the single +12V rail, more than enough for a single high powered graphics card, or two lower demand models in SLI or Crossfire.

  1. Something is a bit off (pics tell me it’s the second quote),

    “is a non modular power supply so all the cables are hardwired into the chassis.”

    “This is a pure modular design, with no cables hardwired into the chassis. The modular area on the power supply is well laid out, with all the sections clearly labelled – they are all different connector sizes anyway, so it is difficult to go wrong during the build phase.”

  2. Yes thats rogue text, fixed, thanks!
