Enermax Infiniti 720W

It undeniably packs amploads of volts. But what about connectors and the garnish?

Enermax sure makes some nice power supplies. Add the Infiniti 720W to the list.

Built like a small elephant attached to a rhinoceros who’s building the brick shithouse in question, it also sports a 135mm transparent fan at the top. It’s definitely not the quietest power supply we’ve put our auditory funnels up to, but the noise generated is low pitched enough to not annoy and will all but disappear in the realms of a case. Pure silence pundits though should look elsewhere.

It’s modular, with the connections being shaped like a PCI-E power connector, but keyed with an empty socket at the top right.

The big feature of the Infiniti 720W is what Enermax amusingly calls ‘Direct X 10’ compatibility. What it comes down to is an updated PCI-E power connector that comes in eight pins rather than six. This will support newer graphics cards, of which the X2900XTX should be the first, featuring one eight-pin and one six-pin power connector.

The Infiniti won’t however support dual 8800 GTXs unless you have a power adaptor handy to convert some four-pin molexes over, as it only comes with three PCI-E power connectors in total. This shouldn’t be an issue for most, as a majority of video cards come with one.

A handy status light sits on the back, that lights green for normal, orange for standby, and turns red, blinks and starts beeping when things go horribly wrong, to warn you in time before the smoke escapes.

Plugging in the nearby multimeter the 12V, 3.3V and 5V rails returned 12.25V, 3.35V and 5.15V respectively. Put under load by booting up 3DMark06 and setting it to 2560 x 1600, 8xAA and 16xAF, the power supply didn’t budge at all, maintaining the exact same volume.

When you look at the price, $300 is a good deal, putting it price-wise on par with OCZ’s Evostream. For anyone but the most demanding of silent PC users it’s a good choice, and we’d be more than happy to have one of these in our machines.
