Shhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh! You're clicking that mouse too loud! Today's sample marks my very first foray into the world of PC Power and Cooling products, and since they've called it the Silencer I can only assume that the lab will have to be as quiet as possible in order to hear this one working. You, in Seattle - do you have to be playing Andrew W.K. right now? You can party hard later, I need the silence.
Ah, that's better. As mentioned, today's review sample is the PC Power and Cooling Silencer 910 watt unit. This power supply in particular has been long awaited by PC P&C fans, as the venerable Silencer 750 is now several years old. When will PC Power and Cooling come out with a more ear friendly unit than the Turbocool 1kW, people wondered. Well, wonder no more because it's here. And it has 80 Plus Silver certification, too.
Spinning the box around in a random direction, I came upon this interesting panel, where there is a comparison diagram between the Silencer 910's cooling setup to that of a "common power supply." Can you see the difference? I can't see the difference. Oh, wait... they're referring to that gap between the PCB and the fan. Wait, that's it? Uh... ok then.
The marketing hype starts with this box panel and a declaration that the unit is only good for 910 watts at forty degrees. In this respect, it's rated very much like the 750W unit was, unlike the fifty degree rated Turbocools. Now, let's see some hands - anybody want to see my hot box get above forty? Excellent - over forty it is.
Some of the other marketing goodies include:
Up to 90% (10dB) Less Noise per Watt
-less than what? A Turbocool? A jet engine? This can of Mountain Dew fizzing away beside me? Blasting an homage to bean burritos in church in the middle of a sermon?
NVIDIA SLI Certified (Multiple GPUs)
High Efficiency (85%); .99 Active PFC
-80 Plus Silver requires 85%-88%-85% at 1/5, 1/2, and full loads to qualify for that level.
+12VDC @ 74A (Powerful Single Rail)
-I guess we needed a pointer just in case we mistook a 74A 12V rail as weak in some way, I guess.
Rock-Solid, Super-Clean DC Output
-usually, PC P&C means business when they say something like this - we'll find out on pages two and three how rock solid this unit is.
24-pin, 8-pin, 4-pin M/B Connectors
Quad PCI-E and 20 Drive Connectors
Automatic Fan Speed Control Circuit
5-Year Warranty and Tech Support
Moving on, this side of the box has more hype in the way of a bunch of icons across the bottom. There's not much here we haven't already seen on this box, but a couple of them do restate that the unit is ultra quiet with an air gap between the PCB and 80mm fan to reduce heat retaining clutter. We'll see about that later.
The back of the box has even more marketing, along with a nice picture of the unit with the cover off. The marketing bullet points are merely several points from above that have been restated.
Opening up the box, we find that the power supply has been fairly well packaged in foam with a user guide thrown in on top.
Speaking of the user guide, it features warranty, specs, and installation instructions in several languages. Along with more "hey... we're awesome" marketing.
And here we have the contents of the box. One power supply, one power cord, a case badge, a manual, and some screws.
The unit itself is finished in *dreamy sigh* matte black, my favorite color for computer power supplies. Despite this, there's something... I don't know... somehow off putting about that big "Silencer" label on the side. Like it was done on that old inkjet of mine that always looked off color and out of focus. Maybe it's just the lab lighting. Or maybe it's just too big.
As you can see, the fan hub has a "Silencer" label on it as well.
The sleeving is just what I like to see... simple, understated, and right up into the enclosure. That last part is particularly important when a unit is lacking a protective grommet at the housing, as this one is.
Yeah, I just don't know about that label. You know, maybe it is too big for my taste. Or maybe Mr. Fuji had some bad sushi again. You say cameras aren't supposed to be fed? Well, just you try telling that to Mr. Fuji. I hope you know Judo.
The load label is done in a simple black and white, affixed to the top of the unit. Now that's my kind of label - bland as a water flavored popsicle. The UL number, e131500, turns out to be PC Power and Cooling's own listing so there's no OEM identification help there. But, let me save you some time - it's Seasonic. 12V total power is a respectable 888W, which is most of the total capacity of the unit in general.
PC P&C Silencer 910W
As is normal for PC Power and Cooling, the "modular cables" thing is an unfamiliar concept on this unit. Everything is hardwired, and given the sheer number of cables on this bad boy that can lead to quite a mess if you're not careful. Interestingly, PC P&C has opted to throw in exactly two of these little dealies:
These are caps for the 5.25" Molex connectors. It's a nice idea, as these connectors have the potential to short out on one's case if not careful, but I would have thrown a few more of these in. There are seven such connectors - one cap for each would have been most welcome.
Type of connector:
PC P&C Silencer 910W
ATX connector (480mm)
8 pin EPS12V (570mm)
4+4 pin ATX12V (565mm)
6+2 PCIe (580mm)
6 pin PCIe (570mm)
5.25" Drive (450mm+120mm+120mm)
3.5" Drive connectors (+120mm)
5.25" Drive (610mm+120mm+120mm+120mm)
Unit Dimensions(L x W x H)
180mm x 150mm x 86mm
Adding to the cabling nightmare is the fact that several of the cables are differing lengths. Each SATA cable for example has a different length to the first connector. And in a nonsensical turn, the two 6 pin PCI-E cables are 10mm shorter than the 6+2 pin cables are. For those few of you who need two 8 pin EPS12V connectors, PC P&C has you covered on this unit.
