The Riotoro 1200W Builder Edition has been released for users who aren't bothered about RGB lighting, distinctive external design or other extras. It packs high power at a fair price – something that was the holy grail a few months ago, when mining with GPUs was still profitable. However, the situation has changed and with GPU mining seemingly in the past now, is this unit worth the £180 asking price?

Riotoro's Builder Edition series has so far consisted of mainstream PSUs, suitable for a run of the mill system. This makes the addition of a 1200W model look slightly odd, since the performance and wattage gap between the next tier down (a 600W unit) is huge. It seems Riotoro wanted to capitalise on the solid bang-for-buck rating its Builder series has been achieving, and thus created the 1200W model we have for review.

The impact of GPU mining was significant not only in the GPU market, but in power supplies as well, so naturally many brands wanted a piece of the pie and released high capacity PSUs, which were in high demand. The problem nowadays is that there is lots of stock of unsold PSUs with over 1kW capacity and the companies that invested money and resources into releasing similar models might never see a profit- or at least the expected one.

While that means it was understandable to go after the high capacity PSU market last year, this target market is not really a focus for the major brands anymore. There is still a market for super strong units, however this is still much more niche compared to the market for low and mid-capacity PSUs.

Riotoro chose High Power as the OEM for its flagship PSU, mainly because this manufacturer is able to provide decent performing products at affordable prices. The registered efficiency is 80 PLUS Gold and ETA-A, while in the noise section Cybenetics awarded it with a LAMBDA-S+ badge.

All important protection features are provided, while the unit's cooling is handled by a 135mm double ball-bearing fan. Apparently Riotoro had tough conditions in mind, like mining, so it chose a DBB fan over a fluid dynamic bearing one, which can offer a quieter operation. Finally, there is no semi-passive mode available, which is a shame in such a high capacity PSU since it could help minimise the noise output under light loads.

The dimensions are normal for a 1.2kW power supply and the provided warranty is long enough at five years. More popular brands offer ten or even twelve years warranty, however we do believe that such long periods are unrealistic for PSUs.

Power Specifications

Rail 3.3V 5V 12V 5VSB -12V
Max. Power Amps 25 25 100 3 0.3
Watts 130 1200 15 3.6
Total Max. Power (W) 1200

The minor rails are quite strong for today's needs, while the +12V rail can deliver up to 100 Amps if/when needed. Finally, the 5VSB rail should be a bit stronger since this is a powerful PSU.

Cables & Connectors

Modular Cables
Description Cable Count Connector Count (Total) Gauge In Cable Capacitors
ATX connector 20+4 pin (550mm) 1 1 16-22AWG No
4+4 pin EPS12V (650mm) 2 2 16AWG No
6+2 pin PCIe (2x600mm) 2 4 16AWG No
6+2 pin PCIe (600mm+150mm) 1 4 16-18AWG No
SATA (500mm+100mm+100mm+100mm) 3 12 18AWG No
4-pin Molex (500mm+100mm+100mm) 2 6 18AWG No
FDD Adapter (+160mm) 1 1 22AWG No
AC Power Cord (1400mm) – C13 coupler 1 1 16AWG

A large number of cables and connectors are provided, including two EPS and eight PCIe connectors along with twelve SATA cables. There are also six 4-pin Molex connectors spread across two cables.

Ideally the ATX and EPS cables should be a little longer, reaching 60cm and 70cm respectively, so as to ensure they are long enough for even the biggest of modern cases. Thankfully larger, 16AWG, gauges have been used in cables that have to deal with increased amperage to lower voltage drops, though the distance between the peripheral connectors is too short at only 10cm. It should be 14-15cm at least.

The PCIe cable that uses a single 12-pin socket from the PSU's modular board, and provides four 6+2pin connectors, does trouble us as well. This implementation can put too much stress on the socket and the corresponding connector.

Today we are analysing the new Cooler Master MasterWatt Maker 1200, a power supply firmly targeting the wealthy enthusiast audience with sizeable disposal income. Available as a ‘Golden Product' not available to the channel, it can be purchased for an eye popping 399 euros direct from the Cooler Master store. It is a pure modular design featuring a brushed aluminium exterior, Titanium class efficiency, a Bluetooth dongle and it ships with a bunch of other features. Read on for the full review…

Right now, the MasterWatt Maker 1200 watt model is the only unit in this prestigious flagship family, but Cooler Master have plans to release a 1500 watt model, at a later date.

For those interested in OEM partners, Cooler Master are working with Enhance on the release of this product. This is not what we would consider a ‘typical' Enhance mid range design. They are pushing their technical skills to the limit with a feature set targeting flagship models from leading manufacturers.

This power supply can be monitored and even somewhat controlled from a mobile device over BlueTooth 3.0. We have never seen a power supply which features BlueTooth support before, so this already makes it an interesting proposition.

Feature Overview:

  • 80 Plus Titanium Efficiency up to 94%
  • Display and Control live power statistics
  • Power Form Correction: Active PFC
  • Mobile remote control
  • Silencio FP 135mm PWM fan with 70,000 hour life expectancy
  • 7 year warranty
