ICON Loading...

Power packed to the core, the ENERMAX Infiniti EIN720AWT 720W power supply is ideal for the ultra high end multi-GPU gaming system. It's SLI, CrossFire and Quad Core CPU ready, and will add real boost to your beast machine. This modular PSU is designed to deliver maximum power with minimum heat. Instead of a small fan on the back of the unit there is a large 135mm fan on the bottom and the back panel is a minimally obstructive hexagonal mesh interrupted only by the power connector and switch.

The modular design makes cable management easier. The main power cables are permanently attached, while all of the peripheral cables all plug into the back of the PSU. To make installation easier the PCIe cables are color coded. The cables are all wrapped in mesh for a cleaner installation.

Triple +12V rails ensure a balanced power output for your system no matter what the load. Actually, this EIN720AWT supports dual CPUs with quad core, triple graphics cards and up to 18 drivers! With its 80 PLUS Certified, so less energy is wasted as heat or interference, delivering more power to your hungry system!

5 out of 5 eggsStrong since 2007

Pros: 100% stable.

Upgraded everything every year for 7 years and this beast powers everything smooth and stable.
From 8800GTX to GTX780, no problems. Two GTX670 in SLI with 2600K at 4.5ghz, no problem. Etc, rinse, repeat.

Cons: they don't make this PSU anymore

Other Thoughts: Also have an Enermax 400W running strong, for over 10 years, right now it's powering a Core2Quad at 3.8ghz on my old DFI P35 board (booting off an old 60gb SSD). The performance is almost equal to the Ivy Bridge experience.

5 out of 5 eggsbought used and still going strong

Pros: I came here to look at the specifications as I'm planning on upgrading my GPU. I noticed a bad review and just wanted to add my counter review. I bought this computer exactly 1 year ago and it was 3 years old at the time. Its a I7 930, 6 gigs ram, 60 gig ssd, 1tb hdd, GTX 260, which has actually allowed me to play games pretty darn nicely, but I feel its time to move up. So, this rig is 4 years old and going strong. Specs say this PS is Crossfire/SLI ready, so I guess it will handle pretty much any GPU I buy. Thinking about a GTX 770 or 780.

Cons: So far....zero!

Now running a GTX780 no problem.
i7-2600K at 4.5ghz 1.35v clean power

1 out of 5 eggsOwned for 18 Months and died

Pros: Lots of connectors. Hi 720W Rating.

Cons: I would have thought for a ~$150 PSU this would have lasted longer. But Mine has just Died. I did trouble shooting and determined that the issue is the PSU. Hope Enermax will honor the 3 year warranty. They list their # as 1-888-778-7878 ext 108 and this rings to Service magic, not Enermax.
1-888-778-7878 the

Other Thoughts: Hoping for a contact and replacement of this failed PSU.

1 out of 5 eggsConsider other options

Pros: Nice looking power supply with a decent warranty. PSU options and percs are among the best out there. Worked great, but only for a year. Funny, someone else on this PSU review had the same issue, 3 different times.

Cons: Exploded taking out my high end PC components along for the ride.

You might think a surge could have done this, well everything else on the circuit was fine and uninterrupted when it happened.

Granted any PSU could have potentially done this. And that's the point. Save yourself some money and buy something that suits your needs at a good price point or another brand that you trust. Enermax is now off my list. It's a shame because I considered them the best till now.

Other Thoughts: All in all, PSU replacement warranties are nothing compared to time and money wasted replacing higher end pc components due to the faulty PSU. an exploding one non the less.
I wouldn't even expect this from a cheap psu that comes with the $50 atx cases no have those PSU ever caused me issues such as this. I will probably never buy an enermax again quite frankly. There is no real benefit from another brand besides some statistics that will mean nothing if a PSU quality is an issue.

Go buy a $200 enermax PSU, have it explode without warning, scare the #$% out of you wife and children, then replace hundreds of dollars of dead PC components. Please send me that same RMA'ed PSU to replace it with. lol See ya later Enermax!

Once this is RMA'ed (if they even replace it), I am going to sell it. This WILL NOT go back in the box I have to rebuild. Do you blame me?

2 out of 5 eggs1 year 3 months and dead

Pros: Quiet and good looking component. Cool guard system. purchased at Newegg on 8/26/2007

Cons: Right after my last review on 8/09/2008, it started acting funny like it lost power and it had to be reset frequently. I thought it was a bad motherboard and packed it away for later use. Two years later I dig it out of storage and try to use it on another build without success. Plug it in and push the power button, fans spin and lights come on and then power protection alarm goes off and it shuts off. Have tried four different motherboards of varying power requirements and no luck. Of course the warranty is now as dead as my $219 power supply.

Other Thoughts: Get the extended warranty if you decide to get this unit. Your gonna need it. I will not buy another Enermax product. You shouldn't either. I have lost my trust.
