Cooler Master goes to Japan for a top-of-the-line PSU

Phrases like "100% Japanese capacitors" are thrown around on all different kinds of computer and electronics items. Cooler Master went one step further and partnered with Japanese electronics house Murata to develop and build the informatively-named MasterWatt Maker 1200 MIJ power supply. The 1200 predictably stands for the 1200W output on offer, and MIJ is "Made in Japan." Cooler Master says the Maker 1200 MIJ is 94% efficient, which should be superior to even the coveted 80 Plus Titanium rating. 

A single 135-mm Cooler Master Silencio FP fan is responsible for cooling the 1200 MIJ. The manufacturer says the fans' "loop dynamic bearings" are self-lubricating and dust-proof for extended periods of operation. The MIJ runs in silent mode when system load is under 50%, which should quiet things down and extend the life of the fan even longer.

A total of 18 flat-ribbon, detachable cables are included with the fully-modular unit. All the wires are black, so those with chromophobia can breathe easily. Cooler Master says the cables have a unique connector design that's safe for 50% more power capacity than normal connectors. The company specifically notes that this connector type is not used on the ATX connector.

The promised quality of the MasterWatt Maker 1200 MIJ comes at a cost. The power supply carries a $1200 suggested retail price, enough to buy a grand total of 30 Corsair CX430 PSUs. Cooler Master backs the MIJ with a ten-year warranty.

    Yawn, wake me up when PSUs are 10c/Watt.

    I think I’ll pass on. $1,200 PSU. Interested to see how many of these are sold, or if it’s just a halo product to generate buzz.

    So how many of these units will you guys be giving away at the TR BBQ?

    Skookum as frig. Could only be improved build-quality-wise if the boards got a conformal-coating dip.
    Sadly, I can no longer bring myself to buy anything bigger than SFX-L. That PSU alone is [url=https://smallformfactor.net/forum/threads/stx160-0-the-most-powerful-atx-unit-in-the-world.934/<]big enough to fit an entire system in[/url<]!

      A NUC system can fit inside a SFX PSU housing. So what? (Cool link though)

        • psuedonymous

        Because that’s a full-up VR-capable gaming rig that fits in the space a PSU could occupy.

    The MasterWatt Maker 1200 MIJ does not quite make enough power to power my MIM Telecaster.

    What I find really incredible is that the PSU uses so little of the incoming energy to transform it into another form. All the components have to be extremely low loss!

    does the 10 year warranty cover changes in the pin layout/spec due to new form factors, new pci-e connectors, new drive connector requirements, etc? i mean, made in japan should probably still carry some premium, but not square watermelon premium.

      • Neutronbeam

      Why would the warranty cover that? Does your car warranty cover new types of drive trains, self-driving technology, new fuel mixes or changing emission standards? It covers what it delivers now. As for some of your points, I’ve found that someone will always come up with adapters to retrofit existing connectors.

        • DreadCthulhu

        A counter-example would be that a lot of high end CPU coolers will ship free adapters when new CPU sockets are introduced. Asking for a similar guarantee of new power adapters at this price point doesn’t seem too out of line.

        • albundy
        • 3 years ago

        why wouldnt it? you’re paying far beyond premium. i expect more than white glove treatment for that cost.

        • VincentHanna

        except you aren’t buying a car, you are buying aluminum wheels or a fancy exhaust for your car…

        And I don’t know about you, but if, for some reason I bought a new car, and the rims themselves weren’t in a smoking heap at that point, then yeah, I’d probably want to bring them along to the new car… especially if the rims cost as much as the car.

      Quality does not equal future proof. The primary use case for this is if you have a client with deep pockets who wants a machine built that, once powered on, will not come down for the next 20 years for any foreseeable reason. That, or professional over-clockers who want as much power draw with as little energy lost as heat as possible.

        • Den2

        The performance and build quality are not the same thing. The performance of this is below some of the competing titanium PSUs but build quality is far ahead.

        [quote<]professional over-clockers who want as much power draw with as little energy lost as heat as possible.[/quote<] I don't think they're bothered by energy loss/heat in the PSU. It probably has more to do with jitter/voltage drop.

    • EzioAs

    In case anyone is looking into the performance and quality of the unit, the review is out on JonnyGuru [url<]http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story&reid=508[/url<] Aris from TechPowerUp will probably publish his review soon.

      • MHLoppy

      I was kind of hoping that at this price point, it would at least match the current “normal” high end power supply designs while maintaining its build quality.

        • EzioAs
        • 3 years ago

        While it would be neat, most of the people in the JonnyGuru forums kept mentioning in a lot of discussions that having the mythical level voltage regulation and incredibly low ripple wouldn’t really affect the usage of a computer. I’m assuming that’s why Oklahoma Wolf gave a 10 for the value despite the high price and not perfect performance score (which is already more than great) because probably to him, build quality matters more at this level.

          • MHLoppy
          • 3 years ago

          Yeah, it’s totally fair since once you get to good to very-good levels of electrical performance, improving build quality is probably going to be more valuable to the user than strictly improving the performance further. They already nailed the efficiency as well, which is great.

    I demand lifetime warranty. At least 20 years warranty and lifetime support. Only then the price makes sense.

      The beast is reviewed on JonnyGURU btw…

      • BenBasson

      It surely still does not. Corsair AX1200i comes with a 10 year warranty for approximately 1/4 of the price of this thing. By that measure you’d really want a 40 year warranty to justify the extra expense.

    No gold plating, no solid silver cables, no RGB LEDs – – no sale. What kind of junk are they trying to push on us?

    • Voldenuit

    Call me a pleb, but I’m happy with my Seasonic X-650.

      • Neutronbeam
      • 3 years ago

      Pleb! There, called it.

      • CScottG
      • 3 years ago

      It’s good to be a pleb, specifically $1100’s good.

    • Captain Ned

    I know I’m a bit behind, but the ATX and +12 pinouts on the back just look wrong. Not enough pins on one, too many on the other, and not enough in total.
