ABS Majesty MJ1100-M 1100W Power Supply Review

ABS has a long history in the do-it-yourself computer components market. ABS was the company that spawned the creation of Newegg. ABS has had its own computer power supply line for some time, but overall the products have been weak. Is the latest ABS Majesty true royalty at 1100 watts, or another PSU court jester?

Overview

The first thing we are going to look at with the ABS Majesty 1100W is its packaging, accessories, and documentation. While normally none of these items is a make or break item for a power supply the packaging quite often contains a lot of information about the product we are purchasing. The inclusion of an owner’s manual that provides actual information about our product is also of great help. Accessories are almost unnecessary with a power supply as the unit is self contained, unless it is modular, but there are cases where a manufacturer can include useful accessories to make installation, routing, and use more efficient.

The ABS Majesty 1100W packaging comes trimmed out in black with gold lettering that is fit for royalty. However, other than the Majesty name, 80Plus Gold logo, and ABS name there is nothing to see here on the packaging. A quick check of the 80Plus website does indeed find the Majesty 1100W certified for 80Plus Gold. Since there is no other information on the packaging the remaining information we break out in the tables below comes from the user manual. This includes the fact that the unit is backed by a 3 year warranty. That is really short for a unit that is marketed as being a high end unit such as this one, and very disappointing coming from such a big company as ABS/Newegg/Rosewill.

The power label for the ABS Majesty 1100W gives the picture of a fairly modern 12v oriented design. We see that while being a DC-DC secondary design the 12v rail has "just" ~90% (or 83A) of its capacity available to the 12v rail. The minor rails have a possible capacity of 200W combined which is certainly on the high end for modern designs. Together with this output we find that the Majesty 1100W has six PCI-E connectors (these are all modified 8-pin connectors), two EPS connectors, and a whopping twenty four peripheral connectors (twelve Molex and twelve SATA). If you need more connectors than this on a unit currently, we don't know what to tell you! Once we dig into the manual though we find a few of interesting points about this units power specifications. Among these facts are that the OCP settings for every rail are significantly higher than the rated output. The manual places the OCP for the 3.3v rail at somewhere between 30A and 45A while the 5v rail is set to trip somewhere between 35A and 50A. The 12v rail does not get proper OCP protection at all, rather the unit relies on the OPP to trip and shut it down. While this method does work, it is obviously not the best way to current limit the unit.

Once we open the ABS Majesty 1100W box we find the power supply, the power cable, mounting screws, modular cables in a bag, and the user manual. The user manual that comes with the ABS Majesty 1100W is 8 pages long. Included in the manual is the power table (for both the MJ800-M and MJ100-M), the connector count (for both the MJ800-M and MJ100-M), some basic installation instructions, some basic troubleshooting steps, a map of the modular interface, pin-outs, and warranty information. The ABS Majesty 1100W manual is very useful with a lot of the very good information we would expect to find a high end unit from a reputable brand. Let’s move on and see what the unit itself looks like now.
