The Wee SilverStone SX700-PT 700W SFX PSU
882W Per Litre!
That power density is a perfectly cromulent measurement for a PSU that measures 125 (W) x 63.5 (H) x 100 mm (D) or 4.92″ x 2.5″x 3.94″, a total area of 48.4623 inches or 0.79 litres. Thankfully the Flexforce cables don’t share the small size of the PSU and range from 13″ to 23″ and includes an impressive array of cables as well, you get two 8/4-Pin EPS connectors. four 8/6-Pin PCIe connectors, a half dozen SATA, three 4-Pin Peripheral connectors. a 4-Pin Floppy and of course a 24/20 ATX power connector.
The FPS Review strapped it onto the test bench and saw efficiency that ranged from 90.82% to 92.61% at 120v AC, even with the tiny design. Any ripple they saw was well within specifications and even better, the fan on this unit was quiet and didn’t really become noticeable until they fired up a serious torture test. That is a bane of many SFX PSUs, which tend to be rather loud even under a low load. The five year warranty is quite acceptable and the price is as well, considering the form factor.
The SilverStone SX700-PT is a very good unit that is squeezing a lot of power out of a very small package like the SX700-G before it. The SX700-PT gave us very good/excellent build quality, very good voltage regulation, good DC Output Quality, and good Transient Load results while also being very quiet.
