Minor error

Quote:
Usually ultra low-end power supplies (i.e. cheap units) present efficiency way above 80%, but with this one efficiency was touching 80% when we pulled between 40% and 60% from its labeled capacity (i.e. between 160 W and 240 W). At full load, however, efficiency dropped to around 73%.

Its hard to ask for better performance for $30 as it does meet minimum ATX12V requirements including protections. This is not criticism of the conclusion but of the standards. I do agree a few extra bucks for better performance for the rest of your computer investment is warranted.

Fixed, thanks a lot for letting me know.

I couldn't agree more with you. I personally would not buy this unit, I'd rather spend a little bit more and buy a unit with better efficiency (ModXStream Pro from OCZ seems to be one of the best picks on the value segment at this moment), but as you know that are people that are still very tight when it comes to picking a PSU. At least this one won't blow the user's computer...

Cheers,
Gabriel.

I also think the power factor is an important parameter. With this PSU it's down below 0.56 in test 1, which is way below what's healthy.
In test 5, where 395.4W is delivered, an apparent power of 801VA is drawn from the wall socket.

Even if the PFC is passive, it should be able to do better than that!

Cheers
