Xigmatek NRP-MC751 750w Power Supply

We have seen Xigmatek shine and fail when it comes to building computer power supplies. How does the company do today with a $110 (after $20 MIR) 750 watt power supply? Once again we get to see if “No Rules Power” violates ATX rules.

Introduction

The Xigmatek brand is one of the newer faces in the enthusiast DIY market having been launched in 2005. However, Xigmatek’s parent company may be more familiar to the storage minded individuals as Micro Technology Concepts, Inc. or MTC Direct which has been around since 1989. With the establishment of the Xigmatek brand Micro Technology Concepts, Inc. has expanded into some new niches as they now brand products that include CPU coolers, VGA coolers, fans, and power supplies. Having moved away from their roots of distributing storage products Xigmatek has chosen Channel Well Technology as their OEM partner for the NRP series of power supplies. Today we have the 4th Xigmatek branded unit in for review and this unit is the Xigmatek NRP-MC751 and is a member of Xigmatek's line of MC "No Rules Power" units that slots in just below the NRP-MC851 we previously reviewed.

Channel Well Technology was founded and began manufacturing power supplies in 1993. Since 1993 Channel Well Technology products have shown up under various guises including Antec, Xclio, 2theMax, CWT, Thermaltake, Corsair, Koolance, and Xigmatek among many others. While most familiar to our US users under the Antec brand CWT is one of the more complete OEM manufacturers as they have a fairly high level of vertical integration providing transformers all the way up to their well designed independently regulated SMPS.

Second Verse, Same as the First?

The Xigmatek NRP-MC751 represents the second MC "No Rules Power" unit we have seen to date. The first MC "No Rules Power" unit we saw was the NRP-MC851 and that unit certainly had it is share of difficulties resulting in the unit failing load testing twice. Today, we have scaled back 100 watts to the NRP-MC751 and we'll see if those shortcomings are endemic to the MC line or if the NRP-MC851 was simply a bridge too far. Before moving on though, how does Xigamtek place the NRP-MC751 in its lineup of units?

No Rules Power, NRP-MC751, complies with the newest Intel standard ATX 12V V2.2 and SSI standard EPS 12V V2.91 simultaneously. The advanced features, including bead core protection fro(sic) PCI-e connectors, worry-free power failure detector and an over 80% efficiency rating, enable NRP-MC751 to the stable and clean power. No Rules Power proves to be a spectacular performer, and full product line also provides various choices for different kinds of consumers.

The NRP-MC751 product page is almost a carbon copy of the NRP-MC851’s product page, and as such there isn’t much new here. So let’s move on and see what we have to look forward to when we purchase the Xigmatek NRP-MC751 power supply in terms of documentation, accessories, cable count, rail layout, output characteristics, and general build quality.
