PC Power & Cooling Silencer 910W ATX PSU

Cables & Connectors
 
PC Power & Cooling employee's can often be seen clutching crucifixes and mumbling sacred words when they find themselves too close to a PSU with modular connectors. "It's just not right, your cables shouldn't just pull off like that!" they exclaim. Unfortunately for PCP&C though, modular PSU's are very much the 'in' thing at the moment with most enthusiasts not even willing to consider a PSU with hard-wired cables. You only need to look at our recent poll in which over 75% of 2100 voters said they'd only consider a modular PSU as their next purchase to see that PCP&C really are catering for the underdog here....In the retail sector at least.

And here's the bundle of cables now.  As we can see you do really get quite a lot of cables with the Silencer 910, which of course is a good thing if you intend on putting the 910w of power to full use. Each and every cable is sleeved in a black mesh right to the tip and finished of with black heat shrink. Even the small amount of wire between each of the connectors on the Molex and SATA plugs is sleeved to perfection. Good job PCP&C.

 ATX Connector Native 1x 20+4 Pin
 EPS-12v / P4-12v Connector(s) Native 1x 4+4 Pin, 1x 8-Pin
 Molex Connectors Modular 7x
 Floppy Disk Connectors Modular 1x
 SATA Connectors Modular 12x
 PCI-E Connectors Native / Modular 2x 6+2 Pin / 2x 6+2 Pin
 
But wait, maybe I've been deceived by the Silencer's large bundle! According to the chart above you get a total of 4x PCI-E cables, 12x SATA Cables and 7x Molex cables. This is significantly less than the likes of Corsair's recently reviewed HX850W, which weighed in with a total of 6x PCI-E, 12x SATA and 12x Molex. In fact, in it's current form the Silencer 910 has the balance of Molex-to-SATA connectors completely the wrong way round for the average enthusiast who will more than likely require no more than four SATA connectors, but possibly more than seven Molex connectors.

The ATX connector is of the 20+4 Pin variety meaning that a block of four pins can be snapped off the end of the connector to reduce it down to the older 20-Pin standards. Two EPS-12v connectors are also provided, one which can be snapped in half to support the 4-Pin P4-12v standard while the other is native 8-Pin. Similarly, two of the four PCI-E connectors can be switched between 6/8-Pin standards by use of an additional 2-Pin connector for supporting high-end graphics cards.
 
As a side-note, PCP&C you need to make up your mind if you're going to use white or black connectors. Black would be my preference - white is so 90's!
 
 
Internal Components
 
Moving on to the internals of the Silencer 910, the OEM is instantly recognisable as Seasonic with some slight similarities to the X900 reviewed back in 2007. Two large aluminium heatsinks span the length of the unit with horizontal fins designed to make maximum use of the air being pushed through the casing by the 80mm fan.  All cables are neatly bunched together and there are some quite large voids inside the unit which will undoubtedly assist with cooling.

Buried beneath the heatsinks are the two main transformers inside the Silencer 910. The smaller of the two will more than likely be responsible for powering the 5VSB rail which is used primarily for USB devices and also for certain motherboard functions while the PC is in standby mode or indeed powered off. Whereas the larger of the two will have the sole responsibility of providing 12VDC which can then be stepped down via other DC-DC circuitry for poweing the +3.3v and +5v rails.

It looks like I caught quite a lucky break with ID'ing the primary capacitors as if it wasn't for the markings just about visible on the folded part of the jacket, I'd probably be forced to get the soldering iron out. Japanese manufactured Nippon-Chemicon's is the name of the game with specs of 400v / 330uF / 105°C. Similarly over on the secondary side more Nippon-Chemicon KZE's can be spotted. This time with specs of 16v / 2200uF. All good so far.

Lastly we come to the 80mm fan manufactured by ADDA. This is the same fan used inside both the PCP&C Silencer 750w Crossfire Edition and the Silencer S75EPS tested back in 2006. Some things never change eh? The spes of the fan can be seen below:
 
• Model: AD0812UB-A71GL
• Size (mm): 80x80x25
• Bearing: BALL
• Speed (RPM): 3900
• Airflow (CFM): 50.0
• Noise (dBA): 41.0
 
Ok, so now we've got all of that out the way let's move on to the testing and see how the Silencer 910 performs at the hands of our updated load testing equipment.

"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
