PC Power & Cooling 750w Silencer S75EPS PSU



PC Power & Cooling are on the tip of every computer enthusiasts tongue when it comes to power supplies. Delivering nothing but stable power for the most power hungry machines since their launch back in 1986, their range of modern units such as the Silencer and Turbo-Cool have won many awards.

I recently had the pleasure of taking the Turbo-Cool 1kw unit for a test drive, and was thoroughly impressed with the stability of its voltages that remain unbeaten to date. The only gripe I had with the unit was it's high noise levels under load - something which I'm hoping PCP&C have alliveated in the Silencer 750w, which is on the OC3D test bed today.


PCP&C have always liked to keep it plain and simple, packaging their units inside plain cardboard boxes printed with some basic specifications. This makes perfect sense as most PCP&C units are highly unlikely to make their way onto retailers shelves, and are instead either sold through PCP&C's website or one of their global distributors.

The 750w Silencer arrived in a plain white, double-walled corrugated cardboard box very similar (but smaller) than the recently reviewed 1kw Turbo-Cool unit. The packaging does its job perfectly, protecting the unit from knocks and bumps during shipping - even on it's long journey from Carlsbad, USA.

We can see from the front of the box that the 750w Silencer boasts a peak output of 825w, 83% efficiency, 60 amps on the +12v rails and a metallic copper finish - very nice.

The box is separated into 3 compartments for containing the power supply, cables and manual. It's great to see that the power supply is situated in the middle of the box, which should keep the unit safe from anything that pierces the cardboard during transit.

Removing the upper layer of cardboard reveals the Silencer unit in all of its glory. The unit is protected by a large plastic bag which should prevent any scratches or other marks from appearing on its funky copper paintjob.

Included in the box were the following items:
• 1x PCP&C 750w Silencer unit.
• 1x Standard power cord.
• 4x ATX case screws.
• 1x Warranty leaflet.
• 1x Unit test report.

The included test report sheet contains all of results obtained from the testing of the power supply at the PCP&C factory. Just browsing over the page we can see some very impressive results from the rails under load and an efficiency of 83.02%.

Yeah it is a tad on the loud side when under full load. However, after speaking with someone that uses one 24/7 - it remains really quiet for them in their Conroe rig. Its just when you push past 35a on the 12v rail that it starts to pipe up the noise a bit.

IMO they could have chosen a better fan (41dba @ 12v is a bit loud), but they did a good job of keeping it quiet in most situations.Quote
