The side of the power supply is the only place you even see the name of the power supply. Silverstone kept things clean and simple on the rest of the power supply. As mentioned before this is an SFX power supply, at its widest point it is less than 5 inches wide. The casing has a satin black finish all over with the exception of the gold lettering on the side sticker. The side sticker has a breakdown of the amperage for each rail as well as the wattage breakdown. The rest of the sticker is filled with all of the standard regulatory logos. Silverstone did still slip in the 80 Plus Gold ranking though. This is important to keep in mind because not only did they increase the wattage, but the lower wattage model is also a lower efficiency rating.

The SST-SX600-G is a full modular power supply including the 24-pin motherboard cable. To help there is a layout sticker under the connections that shows what each plug handles although other than the CPU and PCIe plugs there should be no confusion. To help with that Silverstone color coded the PCIe plug to match the cable as well.

On the back of the power supply, we have honeycomb ventilation and the power connection. What is interesting though is the lack of a power switch.

I really like the embossed Silverstone logo, it’s simple and not to in your face.

For cooling the SST-SX600-G has an 80mm intake fan on the bottom. The vent is built into the casing, full ATX power supplies will normally use a separate fan grill, but building it into the case saves a little room internally.

Beyond the wattage, the next biggest change was actually with the modular cables. Silverstone went from the sleeved cables to a flat flexible cable. This is a huge change, especially when you consider how small the builds are that use SFX power supplies. The 24-pin cable is split into two flat cables to keep it thin and workable. For cables you get the following.

- 24-pin motherboard power

- 8/4 pin CPU power cable

- PCIe cable with two 6/8 pin connections

- A SATA cable with 4 SATA connections

- A Molex cable with two Molex connections and one 4-pin floppy

As expected, they also include a thick power cable as well.

To really get an idea of just how small a SFX power supply really is I put it with a standard ATX power supply. As you can see it is substantially smaller in every possible way.

When we put the 600 watt version next to the 450 watt version we can see just how big of a change the new cables are, both for usability and also aesthetics. Additionally whole they both have the same sized fan, the 450 watt version has a different fan with glossy blades where the new 600 watt versions fan is flat black. This is reflected in the specifications as well, the new fan doesn’t even turn on until the power supply hits 45 degrees Celsius.

I hope everyone has a great holiday. Before you camp out with your families, check out today's coverage of Silverstones new SFX power supply with an impressive 600 watts in a tiny package

Good read. I would like to add/correct something in your article. The 450W version also carries a Gold rating. There are 2 different 450W models. One is the ST45SF-G which is what I have and it is a Gold. The less expensive ST45SF is also a 450W, but is only a 80+ Bronze. BTW, I have been running my PSU since June of 2013 and it has been a solid unit with not one issue. I certainly will be looking at buying the new 600W if I need another SFX PSU.

yeah the 450w version we covered previously was the older Bronze rated version, the gold model I think came out along side of this 600 watt model
