Mushkin Enhanced Joule 800W Power Supply Review


Closer Look:

The Mushkin Enhanced Joule 800W power supply is finished in a slightly metallic, textured satin black paint that looks well.















The exhaust on the rear of the power supply is made up of a large diamond shaped grill with a fine mesh framework for maximum airflow; mains on/off switch, IEC mains input connector and Active PFC label complete the picture. The cable set is sleeved all the way into the power supply which always improves the appearance and exits the unit via a plastic grommet lined port which prevents damage to cables.



One side panels sports a comprehensive specification and serial number label with a couple of factory test labels and the opposite side is left blank.



The large 120mm cooling fan is covered with a black wire grill that is mounted internally with the base of the unit left blank



The wired cable set is fully sleeved with cable ties and heat shrink sleeving used to securely fix it in position. Blue connectors are used for the PCI-E with everything else in black. Mushkin have opted for chained PCI-E connectors with two 6+2-pin connectors on the same wires which isn’t something you’ll see on most other high end power supplies.


The cooling fan of choice here is the A1225L12S by BTec rated for 12VDC at 0.30A. This fan uses Nano Bearing Technology which is lubricant free and by all accounts reduces friction and noise. The printed circuit board is well laid out and on the whole tidy. A quick search on the internet at the units UL number cites Topower has the manufacturer of this unit. The large primary electrolytic capacitors are by Teapo, not the best but certainly not the worst, and rated at only 85°C working temperature, higher specified 105°C devices are almost expected in high end power supplies these days.



The secondary side capacitors are also by Teapo but of the more welcome 105°C variety. There are a few solid state capacitors used in the Mushkin Enhanced Joule 800W; two of these devices can be seen side by side on the vertically mounted boards which I believe are the 3V3 and 5V regulator boards.



All in all the Mushkin Enhanced Joule 800W would appear to be a solid well made unit with a good set of accessories. The packaging could be better with only a layer of cardboard and a layer of bubble wrap between it and the outside world. Let’s move on and see how well it performs.
