If PC Power and Cooling set out to produce a PSU that delivered excellent levels of efficiency and voltage stability above all else, then (aside from the questionable ripple results) this is something they have certainly achieved. In all of the standard tests the Silencer 910 produced solid voltage outputs and even when placed under a load of 1085w in the 'Max Load' test it still refused to falter. Only in the cross-load results did the -12v rail get a little unruly with the voltage going off the scale to down to -14.47v.
However, when reviewing a product here on Overclock3D we have to take into consideration the results of all similar products we've tested before it and how they performed in all areas. As a result the PC Power & Cooling Silencer 910 is up against some extremely stiff competition with both the Corsair HX850W and Enermax Revolution85+ being tested only a few weeks back.
As much as it pains me to say this (because I'm going to get mobbed by PCP&C fans), the Silencer 910 just doesn't cut the mustard. Sure it's got stable rails and great efficiency, but it simply can't compete with the Enermax and Corsair PSU's when it comes to aspects such as noise levels under heavy load, features and general appearance. The theory about hard wired vs modular connectors simply doesn't carry any weight any more and the 80mm fan layout cherished by PCP&C for such a long time really only works in in server environments where low-profile rackmount cases don't work with a top-mounted 120mm+ fan. If it didn't seem like PCP&C were trying to muscle in on the retail market with fancy new packaging and cosmetic improvements to the 910, then maybe I could be a bit more forgiving and evaluate it as an industrial product, but from where I'm standing at least, it doesn't seem to be the case.
- Stable voltages across all rails at all loads.
- Managed to maintain the stable voltages even at 1084w!
- Excellent efficiency across all loads.
- Improved packaging (thought it doesn't look "industrial" any more).
- Only four PCI-E Connectors. Most manufacturers have moved to six for high-output models.
- The Molex conspiracy strikes again. Twelve SATA and only seven Molex connectors!
- Mixture of white and black connectors. *removes M.J pun*. Please make up your mind PCP&C.
- Running this PSU above 75% load will more than likely damage your ear drums.
- Weird ripple results. Possibly a faulty unit or some other weirdness. But this stays here until resolved.
- The -12v rail fell outside ATX spec in cross-load results.
