"At the reference loads of 20, 50 and 100%, it was 86.2%, 89.1% and 85.3% efficient. This complies with the 80 PLUS Silver requirements but by a very narrow margin at full load (we want to remind you that we have to test our PSUs in our 220V mains although the 80 PLUS certification refers to 115V mains in which efficiency is somewhat lower)."

So basically it means this PSU fails to meet 80PLUS Silver requirements, much like other Aerocool units (I've had Strike-X 600W tested at other site, and efficiency was well below other Bronze units, and yes, it was pretty atrociously loud @full load) as it barely meets baseline eff. values meant for 115V when tested @220V.

Other units tested are pretty much general failures.

"There are electrolytic capacitors from WG and Teapo at the output of the lower-wattage models. Teapo components are high quality but WG capacitors do not have such a good reputation."

1.-The "WG capacitors" are made by JunFu (North Latitude Electronic Co., LTD). "WG" is only the Series name. JunFu capacitors are some of the worst, they fail for no apparent reasons (bad quality).

2.-Teapo capacitors are not high quality, although they aren't that bad they're known as "Cheapo" and tend to fail in a relative "short time", with no apparent reasons and very often with no visible signs of failure (no bulging or leaking, the electrolyte just dries out) however they are much better than the JunFu ones.

3.-Size of heatsinks are a joke, that's why fans need to run at high rpms to keep temps low enough, at the expense of high noise levels.

4.-As time passes the capacitors will deteriorate (it's normal) and will allow an even higher ripple voltage which will go on directly to your motherboard and peripherals, sure; your motherboard have a nice set of capacitors to suppress it, but those capacitors have a life expectancy too, and the higher the stress, the shorter the life so in the long run this will cause damage or at least will short the life-span of your products, the ones that normally are the first to show signs of failure because of bad capacitors are the hard drives and optical drives as they receive directly the high ripple voltage coming from the PSU and they don't have big enough capacitors to suppress it.

*-By "no apparent reason" I meant that even if you keep the capacitors well within their maximum permissible voltage, ripple current and temperature these capacitors will not last as long as they should.

...and I think all this is worth to be stated in a review.
