Hello, again my name is Rodney Reynolds and welcome to another video review. Today I'm looking Enermax Infiniti 720W Power Supply. What's included is the users manual, a pouch to put the modular leads into, two holographic magnets, two case badges, four screws for mounting the power supply in the case, a four Pin Molex to two floppy drive power leads adaptor, a power cable and the power supply. This power supply is available in two wattages 650 and 720; I'm reviewing the 720 model, which is enough power for today’s high-end computer system.
Now how is this wattage determined, well to understand you need to know what rails are? Rails are basically well regulator transformers which convert domestic current into the voltages that your computer system can use.
And there are essentially two different rails the 3.3 size 5 volt and the 12 volt rail. In this particular case, the approximate maximum peak output of the 3.3/5 rail is 160 watts and the 12 volt is 672 watts, which is essentially how the wattage of this power supply is determined. The 3.3 size 5 volt rail is responsible for the motherboard, memory, PCI cards, AGP cards and so on, while the 12 volt rail is responsible for the hard drives, DVD, CD Rom, fans etcetera.
Also, some might be interested to know the peak amps on each rail, while the +3.3 volt is 25 amps and the +5 volt is 30 amps. And unlike some power supplies that only have one or two +12 volt rails this model has three, the +12 volt one is 28 amps, the +12 volt two is 28 amps, and the +12 volt three is 30 amps. There are a couple of important things to remember when selecting in power supply. The first is wattage, determine how to wattage you are going to require by the amount of hardware you will be installing. Generally speaking in medium to high end gaming rate will require a 500 to 700 watt power supply. If however, you're going hardcore and have a multiple video card setup with lots of hardware select the power supply that’s above 700 watts.
Second it should be at or above 80% efficient at typical load. Third it should meet the latest ATX and other current standards, environmental directives, over voltage, under voltage and other protections this power supply meets all current standards. Fourth, I'd recommend getting a power supply that has APFC. APFC or active power factor correction is some thing that also assists the power supply in being more efficient and therefore stable under load.
APFC basically reduces total harmonics, corrects import voltage and that it allows for full input voltage rage. Thankfully this power supply has active APFC. Finally get a power supply that has enough leads for your setup. Let's have a closer look at this power supply, its all steel so it’s fairly heavy. There is one quite, 135-millimeter fan, which is recessed; this ensures it will fit any ATX case. This power supply also has what's cool guard, this keeps the power supply fan and all the system fans running after the computer is shut down. This ensures that the power supply and all the system components stay cool even when the system is turned off. Another unique feature is power guard, this feature warned you off potential failure via the Lad and an audible alarm, and will shut down the computer before any damage occurs.
Here’s the power switch and the power cable connection. This power supply has lots of leads, most of this leads are a modular but the few are hard wired into the power supply and can't be removed. The modular leads are easily attached or removed which is very convenient because you only need to use leads necessary for your particular set up. All the leads are sleeved and this reduces cable mess inside the case and will improve air flow. Additionally, the four Pin Molex sleeves have easy grip connectors which made connecting and disconnecting hardware simple.
Finally have a listen to the 135 millimeter fan. If you have or are building a very high end computer system, you should definitely check this power supply out. It has lots of quality clean power modular leads, a nice large quite 135 millimeter fan it has a cool guard and power guard technology as well. Overall this is a kick ass product.
