Cooler Master Real Power Pro 550W
 |
A Closer Look
The power supply is nothing out of the ordinary when it comes to looks; it is simply decked out in a semi-gloss black paint and has a large 120mm blue LED fan. Since this PSU has the EPS12V specification which requires Active PFC, there is no 115/230v switch on the back of the supply. There is an ON/OFF switch for those times the ATX Power button doesn’t respond.
 The PSU is installed in our NZXT case which ends up installed at the bottom of the case upsidedown. |
 With the camera turned upsidedown, the PSU specs can be read off the side of the unit. |
