Greetings to all you fine Internet people. Today is Thanksgiving in Canada, and I am spending it here in front of the computer writing up a review for you folks. Why am I doing this today? Why am I not sitting around slacking off on a holiday? It's quite simple... I'm thankful to be working. I would rather not just sit around all day waiting to get stuffed full of turkey and instead do something to deserve all that food. Besides... I'll be in a turkey coma all day tomorrow, I'm sure. Best to get this over with now.
Today I'm looking at a cool looking new unit from Coolermaster, in the Silent Pro Hybrid 1050 watt. There is no Prius in this box, rather a power supply that features, according to the box, an integrated 7 volt output just for fans. That's a new one on me.
I caught a little... ok, a lot... of flack on my last review for not being serious enough for some people. So, I'm going to try to be serious for a minute here...
Couldn't do it. I made it 55 seconds, and then went outside to make faces at the dogs. I guess you're stuck with my lunacy, until the wrong person sees me walking up the street doing my best imitation of Conan O'Brien's alligator arms. But let's get back to the pictures I'm supposed to be talking about. The above picture has a few marketing points to tell you about:
Fully modular cables
World's first PSU integrated 7V fan port
5.25" Fan controller for both the PSU and system fans
Adjustable 135mm Super Silent Hydraulic Bearings Fan
90% with 80Plus Gold Certification
Fully modular - that's nice. I like fully modular. But, such designs can also be problematic for voltage stability if the cables don't make good contact. We'll see about that on the following pages.
I do like that the internal fan can be controlled via the drive bay fan controller, but this also raises a few questions in my head. Can the unit be operated without the fan controller? Does the unit have overtemp protection in case Joe Schmoe User insists on running the fan too slow for proper cooling? Will we lose The Simpsons to yet another blasted Seth McFarlane cartoon?
It is really interesting that this unit has a 7V output. To my knowledge, this really is the first time I've seen a power supply with such a feature. I'll have to see what I can do to load test this rail and let you know what it's about.
For more information, please visit our website. These words are repeated in no less than twenty-one different languages. But no Klingon.
Aha! This spec table claims that the unit does have overtemp protection! This is good. Looks like that 7V rail is rated to 1.8 amperes. That should be enough for a fan or two.
Rumor has it there's a power supply in the box. Let me just dig into it a little.
A power supply, some screws, a fan controller, some cables for the fan controller, a warranty business card, a user guide, and a bag full of yet more goodies was found in the box.
Here's the user guide, which is barely two steps above total uselessness. Can the unit be used without the fan controller? It doesn't really say. It just tells you how to install the fan controller and power supply.
Here's the power supply itself, and I do like the way it looks. Looks oddly familiar, to me.
Another angle for your viewing pleasure.
Yeah, this is looking really familiar now. In fact, this is the same plaform as the Silent Pro Gold with a few more features and full modularity.
A side view for you.
Instead of the somewhat tacky looking gold fan grille the SPG unit had, this one is a better looking black and gray affair.
Our load table for the day. I've got to start planning out how to test that 7V rail... the load tester has only so many load banks, and the auxiliary loaders only do 12V as they are presently configured.
Coolermaster SPH 1050W
Max Power @ 40°C
Yes, friends, this unit is only rated to handle temps up to forty degrees. My hot box will probably not care - units this big have been known to push the ambient temps well over forty degrees even with the auxiliary fans on. A few times, I've seen the hot box exceed fifty. We might be challenging that overtemp protection.
Here's the modular connector panel with a handy guide on what does what. Except the interface cable for the fan controller - that one is unlabeled. For clarity's sake, those two 3-pin connectors are indeed the 7V outputs on this beast.
Time to unpack the modular cable bag, which contained a nice 14AWG power cord and another bag of screws along with the usual array of modular cables. Most of those cables are done in black ribbon cabling, which can make them easier to hide in a case.
Type of connector:
Coolermaster SPH 1050W
ATX connector (650mm)
4+4 pin EPS12V/ATX12V connector (710mm)
6+2 pin PCIe (660mm)
6+2 pin PCIe (+95mm)
5.25" Drive (495mm+100mm+100mm)
3.5" Drive (+100mm)
3 pin Fan to 4 pin Fan adapter/extension (470mm)
Fan Control Interface (1000mm)
Unit Dimensions(L x W x H)
180mm x 150mm x 86mm
There you have it, a list of the cables. Interestingly, the main ATX cable has a vsense wire for the 3.3V rail. Why? There's no facility for actually using it as such. The connectors on both ends are identical, and can plug into the PSU on either side. That vsense wire terminates at the same pin on both ends. So, there's no way for the unit to sense what the end plugged into the motherboard is doing. Therefore, vsense stops at the modular connector panel. This could have a profound impact on our voltage numbers in load testing. We shall see.
Meantime, here's the fan controller. There is a switch to toggle the PSU fan between auto and manual modes, a dial to adjust the speed, and another dial to control the speed of any case fans you plug into the back of this controller.
