PC Power & Cooling Silencer 910W ATX PSU

Conclusion

Conclusion
 
Silencer 910If 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.
 
 
The Good
- 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).
 
The Mediocre
- 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.
 
The Bad
- 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.

"PCP&C have always been an enthusiasts favourite. But does their latest 910W model have what it takes to keep up with the competition?"

I refuse to stick a PSU in my build that does not take advantage of a 120mm fan as a minimum. 80mm is ridiculous. Noise is at a premium and with so many PSU's catching up (and indeed bettering) the PCP&C insternals, I cannot see why anyone would plump for one of these other than fanboys.

Gr8 review m8.

Cheers guys.

I think the main problem is that PCP&C are trying to enter a market their PSU's were never originally designed for. Yet at the same time they won't let go of their morals surrounding 80mm / hard-wired design because it's what has always worked best for the server market.

EDIT: Ah, ignore that, the problem wasn't related.

Great review. Some crazyness on the voltage qualities despite the large power they can supply.

For the cash, and in particular the name, I'd expect more from them.

I kinda feel these are the same builds as the 500w classic ones they do, only stretched, perhaps this is their max.

Amazing ... in a disbelieving style. It's like Rolls Royce producing a 6k shopping car, or Ferrari producing a supercar that only does 75mph.

Corsair seem to be dominating the market right now. Although the Coolermaster M1000 is still fighting fit.

PCP&P I am outstandingly disappointed.

Nice review mate,

As W3bbo pointed out, why are they still making PSU's with 80mm fans!! its shocking really. Wonder if they will get back to you re: the power issues.

I have the 750w version of this its a shame this doesn't live up to the same standard

I bought this PC Power&Cooling and I am very happy with this 910W PSU , I plan to swap the ball bearing fan with sleeve bearing fan lubricated ( by myself ) with a creamy Zirconium grease , even a 80mm sleeve bearing fan ( of good quality ) at low RPM speed is inaudible , and the hardware inside my PC only need 150W at full load , therefore inside my case this PSU will be running all the time fresh and cool and extreme silent at very low load

I am here in Europe with 220Volts electricity, therefore the efficiency of this 80+ Silver PSU will be even more higher

Update , my lovely PC Power & Cooling 910W fanless installed in my 90degrees rotated CM590 case

the two 140mm exhaust fans installed on the roof of the case will suck air through every hole/grill at the bottom of my case ,therefore the I can keep the PSU fanless
