Efficiency is Platinum and the PSU is fully modular and Haswell ready. Like every good PSU should, it can deliver its full power continuously while operating at up to 50°C. Its protection features only include the basics as Over Current Protection, which has no sense and purpose in a single rail unit, and Over Temperature Protection, which is crucial, are missing. As already stated, OCP doesn't have the slightest meaning in a high capacity, single +12V rail PSU, but OTP should be there since the unit features the option to run in semi-passive mode.
The cooling fan uses ball-bearings, which will have the fan last for pretty long, definitely much longer than a plain sleeve-bearing fan, and the user has the option to flip a switch at the front to turn this unit's semi-passive mode on/off. The Leadex unit is pretty large, which, however, is to be expected given its high capacity. The warranty is set to five years, a satisfactory period, but we would be happier with seven or, even better, ten years instead, and unit is expensive, which comes as no surprise because of its high-end specifications.
|SF-1200F-14MP Power Specs|
|Total Max. Power||1200W|
The single +12V rail is powerful and can deliver almost 100 A of current, which is enough for four high-end VGAs. The minor rails look kind of weak compared to the +12V rail, but today's system doesn't need more than the 100 W these rails can deliver. We would, on the other hand, like to see a stronger 5VSB rail since it is relatively weak and is generated by exactly the same circuit as that of previous SF Platinum units.
Cables & Connectors, Power Distribution
|ATX connector (600mm)||20+4 pin|
|4+4 pin EPS12V (700mm)||2|
|6+2 pin PCIe (600mm+130mm)||6|
|6+2 pin PCIe (600mm)||2|
|SATA (550mm+125mm) / 4 pin Molex (+125mm+125mm)||2 / 2|
|4 pin Molex (540mm+130mm+130mm) / FDD (+130mm)||3 / 1|
This PSU has enough connectors for its capacity, including eight PCIe and two EPS connectors. All of these are also available at the same time. It features pretty long cables since it will probably go into a pretty large case, which makes the use of dangerous cable extensions that can cause huge voltage drops and even melt under very high loads redundant, and the distance between connectors is sufficient. Some of the main ATX cable's wires and almost all of the PCIe and EPS connectors are 16AWG for lower voltage drops at higher loads, but all other connectors use standard 18AWG gauges.
We have nothing to comment on when it comes to the PSU's power distribution because it features a single +12V rail.
