Enermax Infiniti 720 Watt Modular Power Supply

Enermax has been in the power supply business for a while now, and they've been keeping up with what users want and need in their computer systems.  They are also well known for creating some of the most reliable and stable power supplies.  Today, we look at the Infiniti line of power supplies.  This particular model offers up to 720 Watts of power for your system. It supports what Enermax calls "Dual Quad Triple + 18", which means that it supports Dual CPU's, both Quad Core, Triple Graphics cards, and Eighteen Optical / Hard Drives.  This particular model is the SLi edition, meaning that it is SLi certified. 

An image found on both the box and Enermax's website explains this:

Upon opening the box, you will find the manual; which is detailed, a higher gauge (14 gauge) power cable, modular cables, a molex to floppy adapter, an extra cable pouch, enermax lanyard, stickers, and 4 screws.  Also, there are four rubber covers to cover up unused modular connections.

Here are some of the main features and specifications from the website:

The Power Supply:

The power supply features a graphite colored shell with a rough matte polish, which looks very professional.   An embossed Enermax logo can be seen in the picture above, and is a great addition to its visual appearance.

Looking at the side of the power supply, there is an Enermax label with their model logo on it, the model number and a condensed specification list.  Note that there are three +12v rails, +12v1 and +12v2 supplying up to 28 Amps and +12v3 supplying up to 30 Amps; which is great for peripherals requiring lots of power. It is also RoHS compliant.

The rear (outside of case) features an honeycomb grille to let hot exhaust air out, cooling off the power supply. There is an on/off switch, an AC Power Input, a status indicator light and alarm reset switch.  This power supply offers a full range power circuit and Active PFC, so there is no need for a 110v / 240v switch. The light and alarm are useful for determining problems that may arise.

For example, green with no beeps means that everything is alright. Red accompanied with a single beep or multiple beeps means that there is a problem.  During testing, I did not experience any problems with the led or alarm buzzer.

The Cables:

There are modular connections on this power supply.  The two red ones are dedicated towards PCI-Express graphics, while the black colored ones are for Molex, SATA, and floppy requiring peripherals.

This power supply features the following cables:

-A 24-pin ATX power connector

-A 4-pin CPU ATX Power Connector, with an attachable 4-pin connector to convert it into an 8-pin EPS connector.

-1x 6+2-Pin PCI-Express Power Connector and MODULAR 2x  6-Pin PCI-Express Power Connectors

MODULAR: -9x Molex Power Connectors and 2x Floppy Power Connectors via the Molex to Floppy adapter

MODULAR: -9x Serial ATA Power Connectors.

Cooling:

Cooling is handled by a 135mm fan in this power supply. During testing, the fan was elevated from a low speed to a medium / high speed during testing.  I heard the fan making a slight whirring sound, but it was not loud enough to be annoying. During idle / less intensive tasks, the power supply was quiet, i could barely hear the fan outside of my case, from about 5 feet away.

A unique feature of this power supply is its CoolGuard feature, which keeps the power supply and the system fans on even after the system is shut down.  This can lengthen the lifespan of the components in the computer. This feature did work correctly during testing, my system fans turning completely off in under two minutes.

Inside the Power Supply:

* Taking this power supply apart will void the warranty.

Enermax's internal power supply images shows what is inside this power supply best.

Inside the power supply, there two medium sized heat sinks that offer dense fins to cool down the voltage rectifiers.  There is a large high quality transformer that can be seen inside and a much smaller one beside it.   A Hitachi branded primary capacitor is also seen. 

The fan inside is a Globe RL4T B1352512MB, with a maximum draw of 0.38Amps.

Testing:

For this power supply, the test system consists of the following:

-Antec Nine Hundred Case

-Intel Core 2 Duo E6420 Dual Core Processor @ 3.4 GHz

-ZeroTherm BTF90 Heatsink

-eVGA nForce 680i LT SLi Motherboard

-2GB (1GB x 2) of Mushkin XP2-8500 DDRII-1066 Memory

-320GB x 4 Western Digital 16MB Cache Hard Drives

-2x nVIDIA GeForce 8800GTS Video Cards @ 625MHz Core / 1000 MHz Memory

-Sound Blaster Live! 5.1 Digital Sound Card

-Sony 16x DVD-RAM / 18x Samsung DVD-RAM Drives

-4x 120MM fans, 1x 200mm fan

-2x CCFL Lights

*Voltages are at 'Max Load', running 3DMark06 CPU Test 1 and 2 / Deep Freeze HDR test, and read with a Multi-Meter.

The results are excellent for this power supply, the voltages barely shifted, staying strong.  Everything ran fine during testing; the system was stable and performed the tests as expected.  During the tests, the fan speed did increase and was audible during the Deep Freeze test; however, it was not loud enough to be annoying. When the system is idle or doing simple tasks, the fan was nearly silent, occasionally making a whirring sound.  Installation of this power supply was easy.  Overall, the Enermax Infiniti 720 Watt is a highly recommended power supply.   It is multi video card ready with a two 6-pin PCI-E power connectors, and one 6+2-pin PCI-E power connectors.  The CoolGuard feature of this power supply is also welcome, allowing the system and power supply to cool itself after it has been shut down.  This can potentially lengthen the life span of your computer system.  It can be found in online stores for about ~$220.
