What is the Best 600W+ PSU?

Enermax MODU87+ EMG600AWT Review

Manufacturer: Enermax
UK price (as reviewed): £138.72 (inc VAT)
US price (as reviewed): Unknown

As soon as you get your hands on Enermax’s Modu87+ EMG600AWT you can tell that it’s a premium product – it’s finished in a beautifully tactile, mottled surface and has liberal splashes of gold detailing, hinting at the 80plus Gold certification that the PSU holds.


It’s a good job that this is the first impression it gives too – at £138, the Modu87+, which is manufactured by Enermax in its own production facility, is the most expensive PSU in this group test, despite only providing 600W of power. As with a number of the other PSUs in this test
, the Modu87+ is also modular – a feature that we adore, as it makes for cleaner PC builds. However, we were a little dismayed to see that the braiding, although well fitted, starts a good few centimetres from the modular connector, leaving naked cables between the modular connector and the braiding.

The PSU also features HeatGuard - a useful feature that keeps the fan spinning up to 30 seconds after your PC shuts down to make sure that your PSU cools properly. Despite providing a little less juice than most of the other PSUs here, the Modu87+ offers many connectors, including four 6+2-pin PCI-E connectors. These are joined by a whopping count of eight Molex and SATA connectors, and a single floppy connector.

In a break from tradition, the Enermax's 12V power is provided over three (rather than one, two or four) 12V rails, each of which is rated 25A, with a maximum combined output of 50A. The first of these rails provides power to the 24-pin ATX and 8-pin EPS12V connectors, while the second and third rails split the 6+2-pin PCI-E and drive connections between them.

Testing the Modu87+ proved to be a simple affair, as it flew through our tests without any trouble, remaining stable even when drawing its maximum rated 600W. It was also relatively efficient, reaching a peak efficiency of 90 per cent at 50 per cent load and 89 per cent at full load. While this is a good result, however, it isn’t as good as that achieved by the Antec High Current Pro HCP-750. The Modu87+ was also silent up to 50 per cent load, and even very quiet at 100 per cent load with 600W being drawn from the PSU.

The Modu87+ performed well in our other tests too. The unit’s holdup times were both within 1ms of the recommended 17ms and the peak amplitude of the PSU’s ripple was 17.4 mV; while this isn’t the best result, it’s well within the limits set by the ATX spec. The Modu87+ is a solid, stable PSU with some handy extras. Unfortunately, however, the Antec High Current Pro HCP-750 is also very stable, has more PCI-E connections and provides 150W more power for only a little more.
