SilverStone SX750 750W SFX Power Supply Review


The SilverStone SX750 packaging is virtually identical to the SX700-PT packaging. The front of the package is bare of information save for the 80 Plus Platinum seal. When we check the 80 Plus website we find this unit listed so we will take a look at this a little bit later. The rear of the packaging has, again, gone minimalist but it does have a fan noise graph, efficiency graph, and some advertising about voltage regulation. We also find the power label (reproduced below) and the connector count (reproduced below). The side of the package has some advertising including “Dual Balling(sic) Bearing Fan”, “All Japanese capacitors”, “Full modular”, etc. Lastly, the SX750 carries a 5-year warranty.

The SX750 is advertised as being a single 12v rail power supply with a capacity up to 62.5A (or ~100% of the unit’s capacity) if necessary. The minor rails (5v and 3.3v) have a capacity of 20A each and the combined capacity of those two rails is 120W. Combined with these outputs, we find that this unit has 4 PCIe connectors, 8 SATA connectors, and 3 Molex connectors.

Once we open the SilverStone SX750 packaging we find the power supply, mounting screws, modular cables, the power cord, and the user manuals. The user manuals cover just this model currently over 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.
