Specifications

The unit can deliver its full power at up to 50°C, which is the corresponding recommendation of the ATX specification. The SilentNight-500 is also 80 Plus Platinum certified, and its high efficiency will help it maintain a cold operation due to minimized energy losses. Regarding its protection features: it is, according to Rosewill, equipped with most available protection features, while Super Flower states that the similar Golden Silent 500 W lacks OCP and UVP, but what matters the most here is that OTP (Over Temperature Protection) was omitted, and that protection feature is crucial to a fanless PSU.
The dimensions of the unit are a little bigger than the standard since its length reaches 17 cm, so you have to check your chassis before buying it. The unit's enormous, top-mounted heatsink removes heat out of the PSU's internals, but it also adds a lot of extra weight to the unit. Finally, the warranty is set to five years and the price looks quite stiff.


There is only one +12V rail, and it can almost deliver the full power of the PSU, so it will easily handle two VGAs. The minor rails have sufficient power for today's standards and the unit's category. The 5VSB can deliver 2.5 A max current output, which is the minimum for a modern PSU.

Cables & Connectors, Power Distribution

Cable configuration is adequate considering the capacity of the unit, but we would like to see a slightly longer ATX cable of at least 600 mm and modular PCIe cables that are 10 cm longer. Thankfully, the distance amongst all connectors is sufficient. The +12V and ground wires on the main ATX connector as well as those on the EPS connector use 16AWG wires. All other gauges are of 18AWG size.

Since this PSU features a single +12V rail, we do not have anything to comment on about its power distribution.
