Interior Impressions


This is the first time I have had the privilege of opening up an AcBel-built power supply and I have to say that I am quite surprised at the quality that I see here. Considering its efficiency is better than 80%, the RPP 750W can use a pair of smallish heatsinks in conjunction with the 120mm fan to disperse the heat generated by the interior components. Both the both the primary and secondary output stages are well-appointed but I have a bit of difficulty believing that this design can output a peak of 900W.


The primary and secondary sides present me with my first glance of Elite-made capacitors. The single cap on the primary is a 560uF 85°C affair while the ones on the secondary are all rated at 105°C. Since this capacitor brand is a relative unknown to me, I can’t really comment on their quality other than to say that I have not heard of any widespread failures associated with them.

Something else I would like to point out is the high level of precision fabrication that has gone into this power supply. All of the solder traces are immaculately done and everything is laid out very well on the primary PCB.
