DP033 ATX with single 12V power source 45W
PSU DP033, click to enlarge
The DP033 is an ATX PSU designed to supply a low power consumption PCs from a single 12V power source. The DP033 is direct plug-in to the motherboard, but cables are not available if direct-plug-in to the motherboard is not possible. The DP033 is very similar to 75W DP031 PSU, based on a little another chiper architecture. They both have equal applcation and designed for VIA EPIA M, VIA EPIA ML series of motherboards (pay also attention to application notes for DP31 PSU) .
NOTE that the DP033 does not have a regulated +12 Volt output, but simply passes the 12 Volts of the input supply voltage through to the motherboard. This makes it difficult to use for automotive applications. The wide input range unit is the DP022, which has an input range of 10 to 19 Volts. If you need regulated 12 Volts, then you should choose the DP022.
