Leo gets his grubby mitts on the £900 CM ‘Made In Japan’ PSU

A few weeks ago my colleague Allan reviewed the new Cooler Master Masterwatt Maker 1200W ‘Made In Japan' power supply (HERE). This hand made, limited edition PSU was clearly created as a halo product with a ‘no expense' spared design ethos. I asked Allan if he would send it over to me after this review and he duly obliged. It isn't often KitGuru hands out 9.5 out of 10 scores so I wanted to see what the fuss was all about.

There is no doubt that this HALO power supply is a work of art. From the massive, beautifully designed box to the individual cable pouches which resemble cases for headphone storage, initial impressions are certainly positive – the unboxing experience sets the tone for an upcoming system build.

It is inside the power supply that we can see just how much work has went into the design – ironically, most people who will buy this power supply will never open it. Technically the unit is close to faultless – we documented 96.5% efficiency and ripple suppression is at the highest levels we have recorded in the last 5 years.

Murata are the Cooler Master OEM partner responsible for the design, and when parts weren't at a high enough standard they created them from scratch – just for this power supply. Most of us will never be able to justify spending close to £900 on a power supply, but we can certainly appreciate the engineering prowess that has went into the creation.

Murata have even discussed the fact that they invented a new type of power transformer just for the MasterWatt Maker 1200W MIJ. This won't be used in any other power supply.
