The BitFenix Whisper M Series 850W power supply is finished in black paint with yellow stickers on the side panels highlighting the product name and branding. Its not the most attractively finished power supply but I wouldn't class it as ugly either. The power supply measures 150 mm (W) x 86 mm (H) x 160 mm (D) and weighs 1.6kg.
The large fan is hidden behind a grill with the Bitfenix logo taking pride of place in the center.
The modular panel is located on one side of the chassis. It is clearly labelled and won't cause any issues during the build phase.
The other side of the power supply is home to the honeycomb cooling vent, power connector and power switch.
Both side panels have ‘Whisper Series' stickers in place.

There are four +12V rails and two them are rated lower, at 25A. The +12V rails that handle the six PCIe connector have the higher OCP trigger point.
The first +12V rail is designed to handle the 24 pin ATX cable and MOLEX/SATA connectors. The second +12V rail supports the first EPS connector. The remaining two +12V rails support all PCIE cables.
I know some people like to turn their PSU’s fan side up but not in a windowed case with that PSU, that’s damn ugly, it looks like it was cut by a first year student on a day course. I’d keep an eye out for the Superflower Leadex Gold 850w in white (which I have) or black which occasionally drop down to a very similar price and are a work of art.
