Antec High Current Gamer HCG-520M 520W Power Supply Review

A look inside

 

The cooling fan

Antec chose a simple black 135mm fan,
supplied by Adda. This particular model (ADN512MB-A90) features a ball bearing fan
and can reach a maximum rotational speed of 1700RPM.

Inside the Antec HCG-520M unit

The HCG-520M is based on a Seasonic
S12-2 platform, a moderately popular design among middle range power supply
units. It is noteworthy to mention that even though the heatsinks are quite
small, the internals of the unit are crowded, with a lot of silicon glue going
around (the white stuff) securing the parts mechanically together.

The filtering and rectifying stages

Half of the filtering stage can be
found on a little PCB behind the A/C plug receptacle, while the other half has
been installed on the main PCB. The filtering stage totals six Y capacitors,
two X capacitors, three coils and a MOV.

Primary side

A single Rubycon 330uF/400V
capacitor has been installed at the primary side of the unit. Rubycon is a
brand well known between and favored by enthusiasts. The primary bridge can be
seen mounted on its own small heatsink.

Secondary side

Each and every of the secondary side
capacitors have been supplied by Nippon Chemi-Con, making this product an
all-Japanese affair.
