Conclusions

We were very curious to test a power supply from Akasa, since we’ve never tested anything from them before.

We retested this product on 06/24/2009 with our new precision wattmeter and efficiency showed to be above 80% only if you pull between 200 W and 300 W from this power supply; with any other load efficiency was below 80%. Because of that we had to reconsider the award we gave to this product and we decided to downgrade this power supply to the "not recommended" status.

Also we could only extract 500 W from it after we removed the second ATX12V connector from the +12V2 input from our load tester. With both connectors installed there – i.e., using the EPS12V connector – the power supply wouldn’t turn on. Another thing we didn’t like about this unit was the fact that the two video card power connectors are located on the same cable instead of using separated cables.

On the good side Akasa Paxpower 500 W got very low noise and ripple levels. The length of the cables is good and it presents two cables with three SATA power connectors each, for a total of six SATA power connectors.

Although Akasa Paxpower 500 W (AK-P050FG7) can really deliver its labeled power, power isn't everything and you should look for a product with better efficiency.
