A Detailed Look

The SilverStone SX600-G power supply enclosure features a scratch resistant black matte finish and measures only 100mm (3.9”) deep. The back panel includes a power receptacle but there wasn’t room for a master On-Off switch.  

The power supply uses an 80mm cooling fan made by Adda (AD0812UB-D91), which is rated for 0.36A at 12 VDC. The high-quality fan uses ball bearings for reliability and long life.

The SX600-G incorporates an “intelligent semi-fanless” fan speed controller, which allows the fan to turn off for silent operation at very low loads. In practice we found the fan started to spin as soon as a very light load (60W) was applied but stayed very quiet up to mid power operation.

The SX600-G includes five nicely labeled sockets on the front panel for connecting the modular cables.

The PSU comes with a basic assortment of all modular flat, ribbon-style cables. As we mentioned before, if you find one or more cables are too short for your particular build (especially if you are installing the SX600-G in a larger ATX enclosure) SilverStone offers a complete line of full-size modular cables that can be purchased separately. All of the sleeved cables in the PP06 and PP07 Series will work with the SX600-G SFX power supply.

Once again, SilverStone is using Enhance as the OEM for the SX600-G power supply. The PSU appears very similar to the previous 450W SFX version. A modern design is used to obtain relatively high efficiency (80 Plus Gold) and the secondary features dual DC-to-DC converters to produce the 3.3V and 5V minor rails (on the left side in the photo above).

With the cover/fan and modular AC line filter removed, you can see the internal layout of the SX600-G power supply. The main filter capacitor on the primary side is a high quality Nippon Chemi-Con unit rated for 330uF, 450V, and 105°C. As for the rest of the capacitors (both electrolytic and solid polymer) they are a mixed bag ranging from very good (Nippon Chemi-Con) to average (Su’scon and Teapo).

The large heatsinks on the primary side sit directly below the cooling fan for maximum airflow. The overall build quality appears good and the soldering on the PCBs is also very good.
