Even the flat black paintjob of the CP-520A4, that normally would be nothing special, looks stylish. The 140 mm fan takes the entire bottom side of the housing. There is a red and black sticker on the left side. Right side and top are blank. In the back there are only an AC connector and a power switch as this PSU handles all the voltages between 100 and 240 AC automatically. Honey comb mesh has been used to minimize the air resistance. All the cables except the fan-cable are sleeved and heatshrinked nicely. The connectors are basic black ones and unfortunately the peripheral connectors aren't quick release ones.
Unfortunately the CP-520A4 isn't modular and so all the unneeded cables have to be hidden somewhere in the case.
Inside the PSU everything seems to be in place, but it could look better. The PCB is relatively small which leads me to believe that it's the fan that determined the size of this power supply. The heat sinks aren't too tall because of the over-head fan, but there should still be enough cooling surface for the PSU to run cool.
Specifications & TestsThe CP-520A4 may have been put into market in a hurry because it has so few safety approval seals. Usually the units sold in Finland also have FI and some other approval seals in addition to CE, FCC and TÜV. The power supply is SLI-ready and contains following connectors:
