Efficiency has been upgraded to 80 Plus Platinum, thanks to the new platform that this unit uses. The operating temperature range is pretty wide and compliant with ATX spec recommendations, and protection features include all those available to desktop PSUs. OTP (Over Temperature Protection) is the most important one of them all since the unit is not equipped with a fan, so its internal temperatures will be significantly higher compared to those inside a normal PSU.

The dimensions of the unit follow ATX guidelines with a length of 16 cm, but the PSU isn't fully compliant with the most recent ATX specification (2.31) because it only has one +12V rail, but that is nothing to worry about. Finally, the warranty is very long at seven years. Its price is intimidating but fanless units are expensive.

The single +12V rail is strong enough for a medium system: it can deliver the PSU's full power by itself. The minor rails are restricted to 100 W combined, a power level that will suffice in most cases. Finally, the 5VSB rail has the minimum power output allowed by today's standards. An additional 0.5 - 1A on the 5VSB rail would be nice.

Cables & Connectors, Power Distribution

Modular Cables

All cables are pretty long, and the distance amongst connectors on cables that hold more than one connector is satisfactory. The number of SATA and 4-pin molex connectors is adequate given the capacity of the PSU. We strongly believe that two additional PCIe connectors would highly increase usability. The +12V rail is, after all, pretty strong, so it could easily feed two mid-level VGAs.

The cables of the SS-460FL are fully sleeved and stealthed (all wires are black), and all cables except for the main ATX one are flat. Finally, all gauges are of 18AWG size, which is the standard size.

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