On the bottom
side of the Seasonic X-750 power supply is a 120mm temperature controlled intake fan that sits
behind a honeycomb grill. The fan moves air through the power supply, and out the rear of
the case, keeping the ambient system temperature down. A warranty sticker covers
one of the screw holes, so if you open up your power supply Seasonic will know,
and you'll have voided your warranty in the process. The matte black finish
looks and feels very solid, and isn't as prone to scratches and fingerprints as
a shiny glossy finish would be.
Taking a look at the fan from the inside reveals it's a Sanyo Denki
San Ace 120 (Model 9S1212P4M61), which operates at 12V. Sanyo makes
high-quality fans that generally have long life spans, so this is a good sign.
The back of the X-750 power supply is pretty plain. There is the connector
for the main power cable and the hard power switch. The Seasonic X-750 doesn't
need a 115/230V switch since it supports Active PFC. A honeycomb vent is
included for increased airflow through the rear panel.
A-PFC also means improved efficiency, reduced
heat and less power usage. The side of the power supply gives you all the electrical
information you need for the X-750, including the output of its 12V rails and
overall power output.
The front of the Seasonic X-750 lets you populate every modular
cable individually, which is especially ideal if you're testing only certain
components of a computer system.
There are five slots available for SATA and
four-pin Molex cables (each cable can have multiple connectors), and two for PCI Express power connectors. The CPU also gets a pair of
dedicated ports, as does the motherboard. We'll next look at the cable
bundles that go along with the Seasonic X-750 in their very own carry
