OCC has published a new article on their new Power Supply Testing Methodology

Electrical safety is hardly, if ever, given a thought in power supply reviews, but I think it's important. Why shouldn't a power supply meet the requirements for electrical safety and why is it never tested? Most if not all power supplies sold in the UK will carry the CE mark, amongst others, which implies it was designed to meet the requirements of IEC60950 (Safety of Information Technology Equipment). I will say however, that failures are very, very rare and some will say that this test is unnecessary.
