The Athena Power AP-MFATX40 is a mini ITX power supply that's designed to fit in mini ITX, 1UITX, and other small form factor computers. It's 80 PLUS BRONZE Certified, which means better input AC power usage, and less heat generation and power loss. The quiet cooling fan, with smart fan speed controller, guarantees you better stability and peace of mind. Add in the flair of the Active PFC, the broad input volrage range of 88/264 Volts, and dual 6-pin PCIe connectors, and you'll see why the Athena Power AP-MFATX40 triumps over its competitors.

  • newegg A Perfect Fit Like its name, the FLEX ATX is a compact and flexible Power Supply. Designed for 1UITX rackmounts and Mini-ITX chasses – or as a replacement PSU for IBM SurePOS, Shuttle XPC, or HP Pavilion systems – it can be used to build small media servers, and to supply power for all types of kiosks, and can even be used for small business servers.
  • newegg 80PLUS Certification Saving energy has become an important factor when choosing the correct power supply, and this unit shows more efficiency with its 80PLUS Bronze Certification. The FLEX 400W is one of the latest Flex ATX PSUs that brandishes this certification. Providing efficiency during max and low loads, this PSU lives up to the standards of today’s world.
  • newegg Smart Auto Fan Speed Controller With its thermal fan speed control it will detect the amount of heat generated by the computer and spin accordingly. With this feature built in, worrying about the heat level of a PSU becomes almost non-existent.

1 out of 5 eggssimply the worst thing ive bought

Pros: it powers my motherboard with 400 watts

Cons: its garbage it sounds like a jet, when i first got it it was silent but having it on for more than 2 hours and it gets extremely loud

Manufacturer Response:

Thank you for your reviews on Athena Power product. We apologize the inconvenience caused on you. Athena Powre AP-MFATX40 features a high RPM exhausting fan and a temperature senser to control fan spinning speed for protecting the PSU over heat. In some reason, the over heat caused on not enough wattage to support an ATX system or the system thermal is not ideal. We encourage any user with the similar issue, don't hesitate to contact us. Please call us at 626-810-5008 8:30AM~5:30PM, Monday~Friday. Or e-mail us at service@athenapower.us. Thank you and have a nice day.

5 out of 5 eggsMini-ITX PSU Replacement

Pros: More power than I expected for a small PSU. Generous selection of connectors for upgrading a mini-ITX computer. Physically shorter than other similar power supplies which provided extra space to stow unused cables. Very Quiet. No issues yet with power levels, seems smooth.

Cons: None yet.

Other Thoughts: As a middle-of-the-road brand, considering the physical size of the PSU and the diversity of provided connectors, this is a good offering.

1 out of 5 eggsFailed in 1.5 Years with fire and smoke

Pros: Good Wattage

Cons: Loud
Failed With Fire and Smoke

Other Thoughts: I was lucky I turned off the PC in time. It didn't fry the rest of the system, though. Too bad I threw it out. I had the warranty and forgot about it.

3 out of 5 eggsFan is too loud

Pros: Small, plenty of power

Cons: Fan is too loud - sounds like a high end GeForce or Radeon at full load.

Other Thoughts: Plenty of power and connections - however the fan is very loud, sounds like a helicopter taking off, as such not suitable for HTPC use.

1 out of 5 eggsLasted A Year

Pros: Fit into my Shuttle Case.

Cons: First one had to be RMA'd as it only lasted about one month. Now after about a year, the replacement has died.

Other Thoughts: I am frustrated. This was in an HTPC with very light use, I mean maybe once a month for a few hours amount of use. IT was plugged into a UPC so power conditioning was not an issue. I will never buy from this company again!

Manufacturer Response:

Thank you for submitting your review of our product. We, at ACPC, make great efforts to provide quality products. In this case, we definitely would like to understand the Operating environment and System Configuration. Should any User experience issues, we encourage that our Customer Service be contacted for assistance at service@athenapower.us or via landline at 626-810-5008. Thanks again!

3 out of 5 eggsFollow up to my previous review

Pros: I contacted Athena Power after my PSU failed thinking that I was out of luck due to the timeframe. They immediately started the RMA process and helped me find a copy of my purchase invoice. Even if I hadn't found that, they were willing to RMA the PSU. I am impressed by their customer service so far.

Cons: N/A

Other Thoughts: While I have to wait until the new PSU arrives to see about the quality of the unit, I am impressed with Athena Power's willingness to take care of their customers.

Manufacturer Response:

We at Athena Power apologize for the inconvenience and feel free to contact us at service@athenapower.us or call us at (626) 810-5008 if you ever need assistance, concerns and issues with our products.

4 out of 5 eggs

Pros: Slimmer than Stock PSU. Big 400> 240W.

Cons: only two small mounting brackets non adjustable.

Other Thoughts: This PSU is 1/3 smaller than the stock 240 PSU in my Acer AX3400. It had all the cables needed and then some.

Fit very will in my Mini ITX case.
