SilverStone SX700-G 700W SFX Power Supply Review


The SilverStone SX700-G packaging is small, as you would expect, but fits with the general layout and style of all of SilverStone’s packaging. The front of the package has a pair of columns of advertising that includes things such as “Silent running 92mm FDB fan with 18dBA minimum”, “All Japanese capacitors”, “High efficiency with 80 PLUS Gold certification”, “100% modular cables”, “Strict 3% voltage regulation and low ripple & Noise”, etc. Among those things we see that SilverStone is advertising this unit as adhering to the 80 Plus Gold standard of efficiency and a quick check of the 80 Plus website shows that this unit is indeed certified for 80 Plus Gold levels of efficiency. Moving to the rear of the packaging of the SX700-G, we find the advertising carry over from the front of the package but with pictures, or graphs, and more text accompanying it. On the sides of the packaging, we find the power label (reproduced below) and the connector count (reproduced below). Lastly, the SX700-G carries a relatively short 3 year warranty.

The SX700-G is advertised as being a single 12v rail power supply with a capacity up to 58.4A (or ~100% of the unit’s capacity) if necessary. The minor rails (5v and 3.3v) have a capacity of 22A each and the combined capacity of those two rails is 110W. Combined with these outputs, we find that this unit has 4 PCIe connectors, 6 SATA connectors, and 3 Molex connectors.

Once we open the SilverStone SX700-G packaging we find the power supply, mounting screws, modular cables, the power cord, and the user manuals. The user manuals cover this model as well as the rest of the SX-G line and total of 74 pages in 12 languages. As usual, SilverStone provides some of the most complete documentation out there with the only real gripe being about the warranty information disclosure being that we have to look somewhere else. Let’s move on to the unit itself now.
