With the SX600-G 600W Silverstone has a SFX form factor power supply in its portfolio which offers 600 Watt output power. The unit itself only measures 125 mm x 63.5 mm x 100 mm but still you can get up to 600W out of it. When looking for an 80Plus certificate we find a Gold sticker on this PSU. As usual we’re curious to find out what this 120 Euro PSU is capable of.
