I don't really see anything wrong with PSU measurements being done at ~23C, that's a typical office temperature. Standby power measurement isn't particularly relevant since that will depend on how many loads actually end up connected to the 5VSB rail and enabled, such as wake-on-lan/keyboard/mouse, charging-capable ports and other accessories. There isn't much point in the PSU being sub-100mW standby on its own when the assembled system may have in excess of 10W in standby loads. As for the 'fake efficiency badges', 80+ is a voluntary program, it doesn't have the authority to impose sanctions on companies, the only thing they can do is sue for trademark violations. Even UL marks which have a much stronger international standing due to being safety-related also get faked by Chinese manufacturers all the time on stuff drop-shipped from China due to low probabilities of getting caught by customs. If UL and equivalent marks which are required by law in many countries can't stop fake marks, a voluntary program like 80+ or any other would-be replacements stand no chance in hell.
