Silencer 750 Quad is a 750 W power supply from PC Power Cooling featuring a single +12 V rail, four auxiliary PCI Express power cables for video cards, active PFC, efficiency above 80% and the very traditional ATX looks, with a small 80-mm fan on the rear side. The manufacturer promises that this unit can deliver its labeled power at 40º C and has a maximum peak power of 825 W. Sounds promising, but can this unit really deliver 750 W? Let's see.
