TrustedReviews has posted a Power Supply Group Test of 12 units ranging from 400 to 650W
You might have noticed a small sticker on some electrical equipment that is labelled Hi-POT. What this means is that the power supply has been tested with a high voltage static discharge. To pass the Hi-POT test requires that the power supply doesn’t pass the static charge on to the device(s) it’s powering, as this could potentially cause damage. This is especially important when it comes to computer components, which are very sensitive to electrostatic discharges.Power Supply Group Test
