Enermax Infiniti 720w Power Supply
A desktop PC power supply with your best interest at heart? This Enermax not only gives you high-end power but promises to supply specific attention to failure situations as well as extra cooling when your system needs it.
Overview
The first thing we are going to look at with the Infiniti 720w is its packaging, accessories, and documentation. While none of these items is a real 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 cases where a manufacturer can include useful accessories to make installation, routing and use more efficient.
While the boxes are physically different the first thing we notice in the Infiniti 720w packaging is it is almost identical to the Galaxy DXX packaging in regards to the absolutely huge amount of information the packaging contains, down to the fact the ink is vegetable oil based just like the Galaxy’s box was. Since the packaging of the Infiniti 720w contains such a large amount of information about the power supply we will break it up below in table form. Included on the box in all this information is an interesting table on the back that breaks down the efficiency of the unit as between 82% and 85%, sadly for our North American readers this appears to be at 230v as is documented in the user manual. Also prominently displayed on the box is that the Enermax Infiniti 720w is an "industrial design" rated to run at 40c 24/7 which is slightly different than the Galaxy which was rated to run at 50c 24/7.
Conspicuously absent from all the packaging and documentation is any form of SLI certification. A search of the SLI Zone website though turns up the Infiniti 720w as being certified for 8800GTS SLI. This also seems to be indicated by the SLI certified model on Enermax’s webpage. The Infiniti 720w is also certified for Crossfire up to x1950 as noted on the CrossFire certification page and at Enermax’s website by a separate SKU for the Infiniti 720w. If this has you a little puzzled let me clarify the situation some. Due to the interesting labeling requirements imposed by NVIDIA’s process of certification, an “SLI Certified” PSU cannot carry their competitor’s logo along with theirs. So in order to get around this issue, and get a unit certified by both companies, Enermax has been forced to create two SKU’s for the same product. Both products are the exact same so choosing one over the other is not an issue, just slightly confusing due to the labeling issue. Thanks to NVIDIA for their competitive nature that confuses the consumer and adds cost to the product.
We also find on the box that the unit has a 3 year warranty which is certainly not the longest warranty we have seen to date but it also isn’t the shortest. As is customary to point out, warranties don’t really mean a lot as they can't or don't guarantee quality.
Lastly, the unit is billed as being Dual CPU, Quad Core, Triple Graphics + 18 Drive ready which is a step down from the Galaxy DXX that was billed as being Quad CPU Quad Core Quintuple Graphics + 24 Drive ready.
The power label shows a unit that has 93.3% of its output capacity available on the 12v rails totaling 56A. This an extremely large, though not the largest we have seen, percentage of capacity on the 12v rails and should prove very useful with modern systems as they have become more and more 12v heavy in loading. At the same time the rail distribution would be somewhat confusing had Enermax not documented it so well in the included literature. Finally, we see that the connector count looks capable of the billed Dual CPU, Quad Core, Triple Graphics + 18 Drives but much like with the Galaxy DXX this doesn’t seem to be very practical for the vast majority of users.
The packaging includes the Infiniti 720w itself, a box full of the modular cables, a pouch for those modular connectors, a set of screws, an Enermax lanyard and the documentation. Like the Galaxy DXX the documentation that Enermax provides really is the star of the show. Included in the manual is the rail distribution, all the electrical specifications, warranty information, the decoding of the Power Guard feature (also found on the box), an explanation of the CoolGuard feature (which keeps the PSU and certain case fans spinning after shutdown to exhaust excess heat), and pertinent information regarding this units specification compliance. This is the second Enermax power supply we have reviewed to date and both times the documentation, an area skimped on by so many, has been outstanding. If there is nothing else positive to say about the Infiniti after this review it can not be said enough that Enermax really does an outstanding job informing their customer about exactly what they get in their literature.
