Zalman may be a company that became famous from their innovative cooling solutions, yet they have since diversified into several segments of the market. Today the company offers a wide variety of products, from PC cases and gaming peripherals to audio devices and docking stations.


One of Zalman's first diversification attempts was the release of high performance PSUs, with the company aiming to take advantage of their expertise on cooling in their top-tier products. The company had a very good reputation as a power supply maker, but they essentially froze the release of new products due to parent company Moneaul's scandal in 2014. Zalman legally severed their ties with Moneaul and, despite that setback, is moving on as an independent company.

In this review we are having a look at the most powerful model of their latest PSU series, the ZM1200-EBT. Zalman introduced the EBT series last year but started with units ranging from 650W to 1000W. The latest addition to the series bumps the continuous maximum output to 1200 Watts rated to an ambient temperature of 50 °C, all with an 80Plus Gold certification and a fully modular design.

Power specifications ( Rated @ 50 °C )
AC INPUT 100 - 240 VAC, 50 - 60 Hz
RAIL +3.3V +5V +12V +5Vsb -12V
MAX OUTPUT 25A 25A 100A 4A 0.3A
130W 1200W 20W 3.6W

Packaging and Bundle

Zalman supplies the ZM1200-EBT in a large and sturdy cardboard box, more than capable of providing enough protection during shipping. Inside the box, we found the PSU well-packed and protected between thick polyethylene foam pieces.

The company kept the supplied bundle down to the basics. Inside the box we only found four typical mounting screws, a manual, an AC power cable and a few cable ties.

The ZM1200-EBT is a fully modular design, meaning that every cable is detachable, including the main ATX 24-pin one. With the exception of the 24-pin cable, the rest of the cables are "flat" type ribbon cables, with black wires and connectors. The 24-pin cable is made from typical colored wires, black connectors and is wrapped in black nylon sleeving.

    The only potential issue with the ZM1200-EBT as a complete product is that it is """not""" currently unavailable in any country using 110V AC, including the US.

    I think you meant to say that it "is currently unavailable".

    What ever happened to the crooks in Zalman's parent company? At the time there was concern that some of them might be able to avoid justice by blocking their extradition to South Korea.

    Such an amateur design. Without an inrush current damper, everything from LAN parties to new construction installations where most breakers are now the ultra-sensitive arc fault style will trip every time the cap is deenergized.

    This isn't a wireless speaker or a router that runs at 10w where inrush circuits aren't necessary, it's a kilowatt appliance power supply. I've never seen a product that handles this much current not have a current limiter.

    I would STRONGLY advise anyone with a high current PSU to stay away from units with poor quality cables like this one. For ex. with a r9 295x2 their connectors will simply melt due to overheating, as the AWG is just barely enough for the spec.

    I tend to agree to most of the posters here, it really fails to make a impression to me.
    Since the superb flower coolers i saw a huge decline in quality from this company.
    And what they had on offer was all beaten by the concurrent companies with better quality or really much better performance in cooling, power or other things.
    Everything they released did not really make me wanting to buy any of it.

    TP-LINK router offers a large number of characteristics to the people and so a lot of the internet users prefer to work with them for getting the very affordable features. Because this is a wireless router, you can use various wireless devices with it.
