Specifications
As we said further up, this 400 watt power supply stands out in two ways, firstly due to the fact that there’s no fan (passive cooling) and secondly its 80 PLUS Gold certification (
report available here).
In total, it can supply a total output of 400 watts, almost the totality of which (396W) on the +12V, which is logical given its DC-to-DC design that we’ll look at in more depth further on. The +3.3V and +5.5V outputs can supply 66 watts and 100 watts each, or 100 watts combined, which may seem low when you first look at it but which is ample as even a very high overclocked configuration won’t draw as much: most power in today’s configurations is drawn on the +12V output.
In terms of connectivity, this supply is entirely modular, with:
- A main 24-pin connector (20+4) with 60cm cabling
- An 8-pin (4+4) CPU connector
- An 8-pin (6+2) PCI-E connector with 60cm of cabling
3 ports are also available to plug in one of the four cables supplied:
- A cable with 2 SATAs for a total of 50 cm
- A cable with 2 Molexes for a total of 50cm
- A cable with 3 SATAs for a total of 80cm
- A cable with 3 Molexes for a total of 80cm
Seasonic also supplies a Molex to 2 Flopies adaptor for those who still need this. The power supply also comes with 3 velcro cable clips as well as 5 standard plastic ones, screws, a power supply cordon and the manual.
A very important point and one that is highlighted by Seasonic both on a warning surrounding the power supply and in a note on the casing, the supply has an inversed mounting in comparison to what is usually found: the PCB is situated under the power supply and the grill on top. Make sure, then, to install it with the grill at the top, otherwise you’ll mess up the cooling and therefore the general running of the supply.
