Main Connectors

The back of the PSU housing where the warm air is expelled consists of mainly holes through the housing allowing for a maximum amount of air flow. Above the power connector is a small LED. This is part of the Power Guard feature which has 4 alarm modes which also has a Reset button. The LED is green during normal operations and will change to certain colors forewarning you of impending over volting or fan failure.

The modular power cables are fully braided and shrink wrapped nicely which shows the product's level of attention. I would have liked to see the very ends of the 4pin cables braided as well just to fully finish off the cables. Included in the box are 3 SATA cables, 3 4Pin Molex cables, and 2 PCI Express cables. Again, the rest of the native cables are permanently attached to the PSU which consist of 1 24pin Mainboard cable, 2 (6Pin+2Pin) PCIE 12v cable, 1 (4Pin+4Pin) CPU 12v cable, 1 FDD cable, and 1 Fan connector.

With DirectX 10 video cards such as the Geforce 8800 series now all the rage in top of the line graphics, Enermax has provided a special "DXX" connector that has 8 pints rather than the original 6 pin PCI Express connectors. You can see the main difference is only in the connector size. Enermax made the DXX Connector adaptable to fit another 6 pin PCIE graphics card if needed. Definitely a note worthy option when you have an SLI motherboard with 3 PCI Express slots.

Enermax has enough faith in their Infiniti that they feel very confident that it is capable of powering a system with a Dual Quad Core CPU, three graphics cards (two graphics cards in SLI plus one Physx card), and up to 18 hard drives depending on the drives as well as the motherboard or platform. This amount of power means that the cabling has to be thick and of good wire quality. The cables fit very, very tight in to their prospective ports and seem to make good connection. And with industrial grade external and internal features, wire connections are important.

The extras that come with the Enermax products are mounting screws, manual with plenty of detailed information about the new PSU, 2 extra cool mirage Enermax badges, and a cable bag for any extra cables you don't need. The bundle contents have become the signature items among all of Enermax's top PSUs. As for the Enermax Badges, you can take your pick. They are kind of a cool touch.

Installation & Testing:

There isn't much to power supply installations. Kids the ages of 10 and up are able to figure them out nowadays. It seems that between the motherboard and PSU manuals, most anyone should be able to figure out just about anything. It's also always a good thing to ground off by touching your chassis to remove static first thing. That is probably the most common way to damage your system as you prepare to install any new component. So, ground off!

Test System:

• Intel E6600 Core 2 Duo Processor

• ECS PN2-SLI2 680i Motherboard

• 2x1GB Patriot Extreme PC2-6400LLK

• 4x80GB Seagate 3.5" SATA2

• Geforce 7900GT 256MB PCIE

• Bluegears B-Enspirer 7.1 Theater Audio

• Seasonic Power Angel

After taking several voltage readings with my trusty meter while running Prime 95, it's very obvious that the Infiniti's rails aren't drawn down. Even with multiple applications and drives running all at once, the PSU rarely showed any major fluctuation during operations. The BIOS also indicated very little change if anything across all the rails. Power supplies all have some voltage changes as more power is drawn from them. What I look for is whether or not the voltages fall below their rated specs and any evidence that the rails are fluctuating, or rising and falling too drastically. These things are commonly what can effect your system's life time and stability.

Since, benchmarking programs weren't going to cause a large enough draw to change the voltages, the system was then overclocked. With the E6600 at 3.5GHz and repeating a few rounds of benchmarks, the rails again showed small changes. Running several apps at once revealed the same results. The rails stayed well within any .1 volt fluctuations. 12.19 to 12.24 is only a .05v fluctuation, so I would say that it passes this test.

Less Fluctuating is Better

Enermax states that their Infiniti is only 82 percent efficient. The Power Angel indicated differently with readings that suggest it's better. It is in fact more along the lines of 90 percent efficient under standard system use. If you're wondering if the efficiency of a power supply really matters, it can definitely effect your power consumption as well as your power bill. The more efficient your PSU is, the less draw and wasted power is consumed. If you have more than one machine that tends to be on several hours to days on end, then you would definitely appreciate the lower consumption rate that the Infiniti 720W uses to keep your system powered.

Results:

I recently encountered a strange issue that I believed could be confirmed about some power supplies on the new 680i motherboards. This particular board recently encountered a cold start bug which I haven't experienced since using particular PSUs on a DFI system. Using a Coolmax PSU on the ECS PN2-SLI2 system would randomly fail to post and, or sound any BIOS error beeping or codes. The system often wouldn't do anything aside from the LEDs lighting up and fans spinning. Without altering any part of the system used with the same PSU, the Infiniti was reconnected using the 8pin, 24pin, and 4pin auxiliary cables, as well as one hard drive power cable. The system then powered up just fine, posting, and on to the Windows welcome screen. Thus far after many reboots, the test system has not failed to post or power up. Since the Coolmax has operated without issue in other configurations before and the PN2-SLI2 has also performed flawlessly using several other 600+ watt PSUs, there is most likely an incompatibility issue.

Enermax + Water Cooling + OCZ = POWER!!

As for the Cool and Power Guard features, both accurately do what they are designed to do. The Cool Guard feature causes the PSU fan to spin up any time the PSU or system get too warm. At full load, the fan does gets a bit louder, but not half as loud as the older 80 or 90mm PSUs can get. It also moves a very good amount of air. As for the Power Guard, the Infiniti is quite smart at detecting its load limit and giving the proper indications as it finally shuts down. And yes, the Infiniti will absolutely reach and maintain its specified maximum wattage endlessly.

I've personally always appreciated Enermax and their power supplies. If they rate something to specification, it tends to operate extremely close or better than the listed specs. And though all of the components you could connect and power with this PSU, it would give you a lot more room to upgrade later on. At around $189.00, it is very competitive with other comparable PSUs. However, one must consider the damage an under powered or generic PSU is causing their computer, especially if that machine uses quality components such as Servers, Storage Arrays, and Gaming systems. Ultimately, you get what your pay for. If you buy cheap, then you can expect cheap results.


Conclusion:

Just as we've all come to expect from a tried and true manufacturer, the Enermax Infiniti 720W SLI performs extremely well and is very efficient at it. The Infiniti is as stable as you can get and has the ability to continuously provide its 720 Watts if you ever find the need. The power rails are very steady and fluctuate under a mere .07 volts during operations. Even at full load, the Infiniti kept great form and met all expectations.

It's quality fabrication and attention to detail are very good proving Enermax is just as concerned about their product presentation as any other manufacturer. They are even more passionate about the performance of their power supplies which is very evident in the 720 W Infiniti. This is one powerfully capable PSU that works for any personal or professional computer system. It can be applied to any home based system and can absolutely handle the job of any IT project you might have in mind. Based on the Infiniti's test results and rock solid dependability, I am left with the impression that a full recommendation is in order.
