PC Power & Cooling 750w Silencer S75EPS PSU

Looking Inside

Looking Inside

As with all power supplies that pass through Overclock3D, I'll be taking a look inside the Silencer. By doing this I should be able to get a good idea of the overall build quality of the unit and how it is likely to perform in our tests.

I was quite surprised to see a rather spacious layout inside of the Silencer. The unused area around the cooling fan almost makes me wonder why they didn't reduce the size of the casing by around 10mm to make the PSU even more appealing to people with limited space inside their cases. However, the layout of the internal components combined with the two large aluminium heatsinks allows for excellent air flow through the unit.

I'm always on the lookout for adjustable pots in PSU's that pass through OC3D, as these can come in very handy on increasing the voltages if they droop under heavy load. Unfortunately I was unable to find any on the Silencer, which is a great shame considering most other PC Power & Cooling models have this feature.

As previously mentioned, the Silencer is cooled by a single 80mm fan. A quick search of the internet turned up the following specifications for this fan:

• Dimensions: 80x80x25
• Bearing: BALL
• Speed: 3900rpm
• Airflow: 50.0cfm
• Noise: 41.0dBA

With a noise level of 41dBA when running at 12v, this is not the kind of fan I'd personally associate with silence. Hopefully PCP&C have ensured its quiet operation by keeping it at a low speed whenever possible - other wise we may have a noisy "Silencer" on our hands.

was actually hoping you'd review this psu... gj as usual.. kinda sad how loud it is.. think it would of done better with a 120mm fan. btw the forum linky at the end is broken or no linkage.

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.
