Xigmatek, best known for their performance heatsinks, also market three different ranges of power supply units (PSU); the No Rules Power brand, launched in 2007, targets  the popular (NRP-PC), modular (NRP-MC), and high power (NRP-HC) market segments.

No Rules Power

The No Rules Power classes are broken down by consumer classification. The simpler and most expansive range is the Popular Class, abbreviated NRP-PC### and ranging from 400W to 700W. The top of the line NRP-HC series starts out at whopping 1KW and climbs through 1.2KW to top out at a boggling 1.5KW. In the middle lies the subject of today's investigation, the MC series - modular class.

Xigmatek NRP-MC751

There are three power options in the No Rules Power Modular Class; 650W, 750W, 850W and an as yet unannounced 1KW. They are based on Channel Well technologies' PSH design - used by many other well-known brands such as Lian-Li, Thermaltake and Coolermaster. Xigmatek make a few subtle modifications and tweaks to make it their own.

With an MSRP of $129.99US the Xigmatek NRP-MC751 is in a very popular segment, with competition from the likes of Corsair, Silverstone and Antec - big names, to be sure. Will the Xigmatek MC751 feel at home in the Gentleman's Club, or is it just as uncomfortable wearing Dad's tux to his hang-out?
