3 out of 5 eggsDecent Power Supply

Pros: I needed a small cheap power supply for a smaller case and this did the trick.

Cons: While it comes with a few stupid Dell power connectors it lacks ATX12V (8pin) connector and the PCI-E power connectors are only 6pin (not 8 pin).

4 out of 5 eggsIt lasts!

Pros: Makes power
May outlive most house pets

Cons: Does not make coffee

Other Thoughts: I hopped on and checked my order history to see what wattage this thing was, since I don't have physical access to it at the moment and I'm planning on connecting a semi-beefy video card to it. What's important about this is that I ordered it in 2010. Nearly 4 years ago. That's a pretty decent lifespan, and felt it was worth putting in a review. Of course it's going to croak tomorrow since I praised it because that's how the world works.

2 out of 5 eggsDell Dimension 8400 Compatible

Pros: o It was fully compatible with my Dell Dimension 8400 right out of the box.
o Quiet compared to the aging OEM one it replaced.
o Decently cheap as I paid $34 for it.

Cons: o Doesn't last.
o Almost lasted 2 years.
o Other brands seem to fair much better in longevity.
o Seems like other reviewers have the same issue with lifespan.

Other Thoughts: Contemplating whether I should try another one or just forget it.

If you need a PSU now this one will work. Don't hope it will last however. The Manufacturer is responding but it seems theres only a 1 year warranty to keep in mind.

4 out of 5 eggs

Pros: It is small
It works
It hasn't exploded on me

Cons: It does run a little bit hot but that is fine for what I am using it for.

Other Thoughts: I needed to get a small PSU for an HP Pavilion but didn't want to get their OEM version so I settled for this. It doesn't fit inside of the case but it is small enough for me to just have sit right outside.

I was reluctant with this PSU at first but it has treated me well over the past year.

5 out of 5 eggsNot Athena's Fault

Pros: -Small
-Decently Equipped
-CHEAP!

Cons: Absolutely none.

Other Thoughts: Many people have been complaining about this not being a "Micro ATX" power supply. That is not Athena's fault and is not a good reason to give a bad review, especially when the user didn't even try to plug it in. It works as well as you could expect a PSU this cheap to work. Also, if you read the description, it is clearly advertised as a Micro PS3, not a Micro ATX. In fact, it does not say anywhere in the "Specifications" tab that it is a Mirco ATX. Furthermore, the measurements are right there for all to see. If size is a concern, one aught to take measurements. Here is some advice: If a product is really cheap, like this one, do your homework or at least read the specifications.

1 out of 5 eggsJunk

Pros: Made of metal?

Cons: Does not POST with two motherboards, and killed a third one.

Other Thoughts: The QC of this power supply sucks. The otput voltages are inaccurate. It has thin wire to the ATX connector, and they are poorly crimped. I could go on and on. Too bad I have had it over 30 days, due to my lack of time building a new system, or back to newegg it would go. I would stick to Sparkle or Corsair.

Manufacturer Response:

Thank you for your review of our product. Should any user have issues with selecting the correct power supply, for their specific configuration, Athena Power Customer Service will be happy to help to produce a system power budget. Customer Service can be reached via landline at 626-810-5008 or service@athenapower.us. Thanks again!

3 out of 5 eggsIt works so far ...BUT

Pros: Price was right and it does power the server.

Cons: Listed as being a compatible replacement for Dell PowerEdge SC 440 Server. But it's not really.

1 - Not a perfect fit - It fits in place, but does leave an open gap in the back plane.
2 - Power cables are too short to reach both SATA Hard Drives. I managed to get one SATA drive connected, but not the other. Extension are needed to connect both.
3- SATA connectors are straight, not "L" connectors. "L" shaped adapters are need in order to close the Chassis cover.

Other Thoughts: Bottom line is. It will work as a replacement for the Dell PowerEdge SC 440, but not out of the box.

Manufacturer Response:

We at Athena Power apologize for the inconvenience. We will take your corcerns and comments to our factory if you ahve any other concerns or issues with our product please feel free contact us at service@athenapower.us or call us at (626) 810-5008.

5 out of 5 eggs

Pros: Fits Dell Dimension 8400 perfectly using the 2 original screws.

Working fine now for over a month hooked up to 2 internal SATA hard drives, an SATA DVD drive, and a CD-ROM drive.

Cons: None so far. I'll post again if I encounter any problems.

Original Dell power supply worked for 6 years with no problems, then 2 more years with intermittent problems.

Other Thoughts: Blue LED mentioned by others is *inside* the unit on mine. You can see it by looking through fan opening in the back. It does *not* light up the room.

2 out of 5 eggsAthena Power Supply

Pros: The item is small and fits loosely in the case. It is very quiet and works OK for now. I had to play with the back of the computer case so I can screw in the screws, but fits fine and seems to be secured.

Cons: I had to order a second power supply because the first one that I received came in defective. I then had to pay for the return shipping, which I don't agree since I received a defective product. Either way besides the inconvenience and extra money to return the first power supply, the item is working OK so far.

Manufacturer Response:

We at Athena Power apologize for the inconvenience and if there is still trouble with this PSU please let us know and we will be happy to assist you and provide you with a call-tag for the next RMA if you so need it. Thank you.
