1 out of 5 eggsNo Mas

Pros: Form factor (short depth) fits the original PC.
Works fine when working.

Cons: Died after 2 months of light load.
Warranty replacement requires that customer pay the return shipping of the defective unit (~ $9 thru USPS).
Turnaround for RMA and shipping takes at least 2 weeks.
The first warranty replacement unit was DOA; had to get 2nd RMA at supplier's expense.

Other Thoughts: AP customer service was helpful and responsive, but this product has serious QC issues. With all the time and expenses involved in the two RMAs (so far), I don't see why AP continues to carry this product.

Manufacturer Response:

1 out of 5 eggsonce bitten shame on you.......

Pros: none

Cons: DO NOT BUY. Purchased on sale to repair HP 2001 desktop despite the poor reviews. Dead on arrival. 0 volts at pin 9 before any installation. Had to pay return shipping of $14.34, for a grand total out of pocket of $20.81 for nothing when all said and done. Despite being bitten, ordered the 400 watt upgrade instead with slightly better reviews.

Other Thoughts: I think it is poor business practices to charge return shipping on an item that is defective out of the box. If you are going to sell obviously defective merchandise, at least open the box and run simple diagnostics on the item before shipping. I hope it was not a mistake to order again from New Egg instead of opting for the Best Buy Dynex model.

Manufacturer Response:

Thank you for your review. ACPC strives to provide the highest possible quality with second-to-none customer service. Our products exhibit lower than industry average failure rates. Should any user encounter issues, we do encourage he/she to contact our Customer Service at or via landline at 626-810-5008. Thanks again!

1 out of 5 eggsArrived DOA

Pros: None - DOA

Cons: DOA, like quite a few it would seem from the other posts below..........

Other Thoughts: I purchased this PSU for an upgrade project on a Dell Dimension 2400. Cleeaned out the original PSU and put it back in service - very disappointing.

Manufacturer Response:

We at Athena Power apologize for the inconvenience and we would like it if you can contact us directly at either our e-mail at or call us at (626) 810-5008 and we will be happy to assist you in troubleshooting this issue. Sometimes we have issues with customers who believe the PSU is not working but that is not always be the case and can be other hardware issues. We at Athena Power would recommend all customers call our tech support department before making any returns. Thank you.

4 out of 5 eggsGood replacement for old HP

Pros: Same size as HP OEM psu. Fits in old, small HP case that doesn't have room for regular atx psu. Runs quietly. Enough (4) molex connectors.

Cons: Lead with 20/24 pin mobo power connector barely long enough. Unneeded connectors for P4, video, sata made a spaghetti mess of extra wires to be tied off. Had a bracket that had to be removed because it took up a precious 5/8" of space between back of psu and optical drive.

Other Thoughts: 300 watts is overkill for a pentium III system. Don't know if this will make a difference in the temperature inside the case, but the old psu had air intake slots on the opposite side from the new one. This put the intake slots directly over the cpu cooler so heat could be drawn directly off the cooler.

5 out of 5 eggsIt suited me, while it lasted.

Pros: After one year and 6 months, it died. However, the reason why I still gave it 5 eggs is because for three months, I was using a graphics card that needed a minimum requirement of 400Watts to run. But not only that, later I bought a Core 2 Quad Q8400 OC'd at 3.30GHz which eventually it was to much for the little 300 watt PSU to take and it finally just wouldn't start one day. (Sad...I know) I was very surprised it lasted that long actually.

Cons: However, it did make an odd noise sometimes, without a lot of load.

Other Thoughts: I have respect for this cheap little PSU though...
Ran 2 hard drives
A simple DVD drive
An Oc'd E8400Duo@4.4GHz and an Q8400Quad@3.3Ghz
2 120mm fans, and 4 92mm fans
A Gigabyte G41M ES2H and G31M ES2L
4GB of GSkill DDR2 RAM
And to top it all off, a Nvidia 8800GT OC.
Now for a power supply rated at 300W running that, not to shabby...

1 out of 5 eggsWorked fine...Once

Pros: Price?

Cons: Out of a batch of 5 one died the second time it was turned on. Bought two more as replacements, one so we would have a spare. First one again powered up once and that was it. Board does powers up fine with a full size 300 sitting out of the case.

Other Thoughts: Buy extras, you'll need them.

Manufacturer Response:

We at Athena Power would like to apologize for the inconvenience you experienced and we would like for you to contact us so we may assist you with an RMA so we can immediately get you a replacement for your defective unit. Please send an e-mail to or call us at (626) 810-5008. Thank you.

5 out of 5 eggsAwesome!

Pros: I purchased this power supply in Jan of 2010 and it has been working flawlessly since then (1 year and 10 months so far). I have had no trouble with it. I used it to replace the OEM power supply in my Dell Dimension 8300 desktop.

Cons: none!

Other Thoughts: Cheap and reliable, this was a great purchase for me!
