Mushkin Enhanced Joule 800W Power Supply Review




Price Per the Watt:

Power Supply Mushkin Enhanced Joule 800W at $110.00 = $0.14/Watt (02-2011)


The Mushkin Enhanced Joule 800W power supply proved to be a very capable power supply following the OCC power supply testing methodology. The power supply itself is really hard to fault; satisfactory build quality, good DC voltage load regulation and very low AC noise/ripple in combination with high efficiency are everything the enthusiast needs in a power supply.

If I had to find fault then it would have to be some minor inaccuracies in the information provided, the packaging and a poor user manual. Let’s start with the packaging which is definitely basic and offers little protection against impact damage; one layer of cardboard plus a single layer of bubble wrap are all that’s between the power supply and the outside world and it doesn’t compare with the quality of the packaging of other high end power supply manufacturers. There are also some minor inaccuracies in the information provided, quad +12V rail and an AC input voltage of 90-264VAC in the feature list on the rear of the box when it’s clearly a dual +12V rail power supply with according to the specification table a AC input of 115-230VAC - which is correct? What about the user manual? It’s basically a single sheet of folded paper that has nothing more than the power supply type and model number on the front face, “for Mushkin Enhanced Volta and Joule Series Power Supplies”, fair enough. What I find really puzzling is the first paragraph on the second page telling the user to make sure the 115/230VAC switch, if fitted, is in the right position! Come on Mushkin you can do better than that if you want the PC enthusiast to take you seriously!

Minor inaccuracies aside the Mushkin Enhanced Joule 800W is a great power supply at a great price that will easily power any dual graphics card configuration and I have no hesitation in awarding it the OCC Gold award but it could have been better!
