PC Power & Cooling Silencer 750W Quad Power Supply Review

Output Characteristics


PC Power & Cooling has gone from staunchly supporting the concept of multiple +12V rails to now swearing by large, single +12V rail designs. The ever-changing world of component power consumption has forced many manufacturers to go this same route so it is not surprising that one of the premier power supply providers has done the same.

That being said, the 750 Quad has been give a massive +12V rail output of 60A (or 720W) which represents a whooping 96% of this unit’s total output. Make no mistake about it, this is exactly what we want to see from a quality power supply since graphics cards, CPUs, fans, and numerous other components draw their power from this rail. Other than that, the other rails get cursory consideration which is only natural in the +12V-centric market we presently have.


Interior Impressions


The interior layout of the 750 Quad is quite interesting since from the top down all we see is a pair of horizontally-mounted aluminum heatsinks which are the hallmark of cross-flow type layouts. They are designed in such a way that they take full advantage of the limited airflow the single 80mm fan provides in order to better cool down the components. Also, if some of you were wondering; this power supply is fabricated by Seasonic.


The cap choices on this power supply are straightforward to say the least. Both the primary and secondary sides are populated by Nippon Chemi-Con units which are all rated at 105*C.


According to PC Power & Cooling, they have pushed the PCB about 1/2” back form the exhaust fan in order to increase airflow within the housing. In principle, this concept should work since it cuts down on any obstructions in front of the fan which should increase the amount of air it can remove.

The primary filtering side is quite well appointed with a number of large chokes as well as a separate heatsink for the primary rectifier.
