A Detailed Look
The SilverStone SX650-G power supply enclosure is painted with a satin black finish. The power supply measures 100mm deep x 63mm x 125mm. The back panel includes an On-Off switch, AC receptacle and open honey-comb grill.
The power supply uses a 92mm fan made by Globe Fan for cooling. The nine blade fan (SO921512HB) is rated for 0.45A at 12 VDC and features a Fluid Dynamic Bearing (FDB) bearing for quiet operation and long life.
The front panel on the 650W PSU incorporates eight modular cable connectors, all nicely labelled and color coded. Each blue connector supports a cable with two PCI-E 8/6-pin connectors.
All of the modular cables are flat ribbon-style to assist with neat cable routing and to help maximize airflow. Note that all of the cables are intentionally rather short as this power supply is designed for use in small-size cases.
Under the Hood
Here are a few pictures showing the layout and components inside SX650-G power supply. SilverStone is one again using High Power as the OEM for the SX650-G PSU. The overall layout, soldering, and build quality all look very good.
The power supply features a modern circuit design to meet the 80 Plus criteria for high efficiency and uses DC-to-DC converters on the secondary to produce the +3.3V and +5V rails from the +12V output. All of capacitors used inside the PSU are Japanese made with a mix of solid polymer and electrolytic caps used throughout. For example, the main bulk capacitor is made by Rubycon and rated for 470uF, 420V, and 85°C.
Thanks for the review. I’m a
Thanks for the review. I’m a customer looking to purchase this SX650 or the Corsair SF600 and I noticed you have reviewed both units. However, there seems to be little direct comparison in your review between the two, even though they are direct competitors.
1) Is the fan in the Silverstone removable without cutting and soldering wires? It doesn’t appear so but just looking to confirm.
2) It seems the SX650 runs hotter and louder than the SF600 based on comparing the two tables between reviews. However, this is a test where you are recycling hot air back into the intake. Many cases are designed where the PSU intake is bringing in fresh/cool outside air. Do you think this will affect the temperatures in a different way?

One additional question:
3) The Corsair cables in the SF600 are often accused of being stiff and difficult to work with. Based on your review the SX650 have similar length and variety of cables. Are they also ‘too stiff’ or are they more flexible and easier to route?
