3 out of 5 eggsShort cables. Load PSU

Pros: Seems to have lots of connectors and its small

Cons: Very shirt cables. I have a standard 1u 19" width server chassis and the 20+4 pin connector was close to 6 inches short!

5 out of 5 eggsits goog for a htpc

Pros: it works fine with a6 5600k in my new raidmax element it hasent slept since it was carried in my front door and installed

Cons: at least 2 more sata but for this price ill take a shot.

Other Thoughts: for Darren E.
this is ideal for a small build NOT a slimline .
I own a hp pavilion slimline s5710f for my office
it reqires a (TFX) psu not something of this size
they are around this same price.the air flow sucks on these slimlines its important that you use the right psu with these.i even replaced my chassis fan with a gelid 92mm fan to increase airflow and sleaved the psu cables as well as cable its a little i3 killer it stands up with my i5 devils canyon 4690

1 out of 5 eggsWorked for a month then...

Pros: Not sure. It worked for a while. It was cheap and I accept that I should just buy better hardware. If any exists. It will likely cost more to deal with a warranty so I have decided to just scrap it for the connectors and possibly components.

Cons: Extremely loud. This single PSU is louder when on (even in a idle system that pulls less than 30 watts) than my my quad core T3488 2.16Ghz, GeForce 760, 4 raid5 sata 7200K and 3 120mm fan system. Its also not only loud but very high pitched. The room in which I keep my firewall was literally intolerable to be for any real length of time due to the noise. About a month in the fan started making noises. Maybe a week later and I was moving systems around and I heard a "pop" and my firewall went down. Looking over it today not only is the power supply dead but my mother board is also dead. There is a small arc mark on a corner of the PSU case to the left side of the power cables. Basically just had a 50 dollar PSU destroy a 150 dollar jetway mother board. Very unhappy especially considering I now have ZERO fanless motherboards as the last jetway I ordered effectively lied about being fanless. Beginning to think there are no decent hardware vendors in existence any more. My ancient (15 year old) Epia VIA fanless systems and the 35 dollar cases with PSUs still run to this day. I dont have a single piece of properly working hardware from the last 5 years I have bought that has lasted more then perhaps 12-15 months. Sad.

Other Thoughts: Dont buy this but I dont know what to recommend.

Manufacturer Response:

Thank you for your review. FYI, based on, GeForce 760 VGA card's minimum recommended system power is 500W. Athena Power AP-MFATX22 is a 220W PSU. Athena Computer Power Corp. (ACPC) would like to assist any customer to choose a suitable power supply to fit the system requirements. Please feel free to contact ACPC Service Dept. at (626) 810-5008 or email us at Mon - Fri 08:30 AM - 5:30 PM.

4 out of 5 eggsWorks in Pavilion Slimline PCs

Pros: Had exactly the right power cables for a HP Pavilion Slimline s5704yPC (20+4 pin main connector, 2 x SATA, 1 x P4), and probably other HP Slimlines. There are also floppy and the old style (Molex) power connectors if needed.

Cons: The HP power supply was secured by a total of five screws (3 x external, 2 x internal). This power supply only lined up with two holes on the outside of the case. Not a huge issue as it's smaller and lighter than the HP power supply that it replaced. It did require a little maneuvering to get it into place, but no fabrication (of the PC or power supply) was required.

Other Thoughts: Best Buy wanted two hundred dollars for parts and labor to replace the power supply so this is a great deal if the power supply lasts. It's just a shame that this particular HP PC is a pile of junk - elegant in its design yet slow and unreliable. My smartphone is faster.

As mentioned, the power supply was not an exact fit. However, if you're patient and somewhat mechanically inclined, the power supply will fit and bring your PC back to life.

I also like that the main (large) power connector to the motherboard was 20+4 pins. This means that if your setup only uses 20 pins, you can slide the extra 4 pin connector out of the way.

1 out of 5 eggsEh, not too happy.

Pros: The unit lasted just about two years without any problems.

Cons: The unit failed to start the computer. Upon closer inspection, near the intake vent, I noticed a charred blackened area.

I opened up the device to see what exactly had happened, and the entire bottom lower right (relative to the exhaust fan on the top) was charred black -- including melted capacitors and chips burned to a crisp. I'm happy it didn't start a fire to be honest.

I probably won't be buying 'flex' power supplies in the near future.

Other Thoughts: Don't cheap out on power supplies, folks.

Manufacturer Response:

5 out of 5 eggsGreat replacement for our BlueSocket Power Supply

Pros: We needed to replace the power supply of our BlueSocket BSC-600 High Performance (wireless) Controller. The manufacturer's power supply (SKU: 1700925F1) retails for $190. We purchased one for testing, and works like a champ!

This little guy is 100% identical (except the specs sticker... :P ). So far is working great. As a matter of fact, I'm buying 5 more right now... saving $160 per unit!

Cons: None so far. Will report later. :D

Other Thoughts: I will strongly recommend this to anyone who has an older BlueSocket BSC-600 with a bad power supply.

1 out of 5 eggsSounded Like Jet Engine

Pros: provided power

Cons: sounded so loud i though my cleaner was vacuuming

Manufacturer Response:

Thank you for your review. Our AP-MFATX22 power supply contain a higher speed fan. for better cooling performance in compact environments, as these power supplies were originally designed for Server applications. However, it should not sound like a "jet engine." Please feel free to contact our Customer Service via email at or via landline at 626-810-5008. Thanks again!

3 out of 5 eggsGot HP Slimline running again

Pros: Simple to install and fit in the case nicely. It works so far and that's all that really matters for this outdated computer's repair

Cons: It has a 20+4 ATX power connector so I had to purchase a $10 (with shipping) adapter from online auction site to be compatible with the mini-ITX mobo power connector. For what my computer has (barebones) there are simply too many power connectors.

Other Thoughts: This PSU is shorter than the original HP PSU so there was plenty of room to tuck the extra cables in a non airflow interference spot. Also had to flatten the cases original PSU holding tabs to let this PSU fit flush on the side of the case.
