Under the HoodHere are a few pictures showing the layout and components inside the CM UCP 900W power supply. The overall layout and build quality is very good.
Cooler Master appears to once again be using Acbel as their OEM for this power supply. The UCP 900W uses DC to DC Voltage Regulator Modules (VRM) to produce the +3.3V and +5V outputs from 12VDC.
The primary features three high quality electrolytic caps made by Hitachi, which are rated for 390uF, 400V, and 85°C.
The secondary side of the UCP 900W power supply is populated by both electrolytic and solid polymer capacitors and dominated by a lot of distribution wiring.
In the photo above you can see two of the six solid polymer caps and note that the PCB is designed to accommodate up to six +12V outputs (used on the UCP 1,100W).
