Efficiency is 80 Plus certified, the lowest available certification, and the unit can deliver its full power up to 40°C. Given the budget price, we didn't expect much more out of these areas (ok, maybe for the slightly higher Bronze efficiency certification). Thankfully, most protection features are present; however, OTP is (Over Temperature Protection) missing. We also doubt OCP is present since this is a single rail unit. Also, the low budget didn't allow for a high-quality fan so a sleeve-bearing one was used.
The dimensions of the PSU are compact and fully compatible with the ATX spec recommendation, and its weight is low as well. Finally, the warranty is very small at only one year (It is, strangely enough, three times as long for the EU and Australia), and the price is a little above 50 bucks, making it a good deal if it manages to perform decently throughout our tough tests.
|Silverstone ST50F-ES Power Specs|
|Total Max. Power||500W|
The single +12V rail can deliver a little over 400 W of power, so it will easily feed a small system. The minor rails have sufficient power for almost any system, and the 5VSB rail has the standard maximum current output of 2.5 A.
Cables & Connectors, Power Distribution
|ATX connector (510mm)||20+4 pin|
|4+4 pin EPS12V (565mm)||1|
|6 pin PCIe (510mm+150mm)||2|
|4 pin Molex (400 mm+150mm+150mm) / FDD (+150mm)||3 / 1|
The PSU features a small number of connectors since it mostly addresses mainstream systems with only a few components. A few more SATA connectors would be very welcome nonetheless, in case of a download station/PC. Also, the length of all cables is adequate considering the unit will be installed into a small- to medium-sized enclosure, and the distance among connectors is ideal. Finally, all wires are of 18AWG size, which is the minimum that the ATX spec recommends for almost all connectors/cases.
Since this PSU features a single +12V rail, we do not have anything to comment on about its power distribution.
