The Apevia Turbolink ATX-TL450W-BK is sold as a 450 W unit, but it can only deliver 240 W. Having a fake wattage is the smallest of its problems: it is a piece of junk that can damage your computer, since it provides noise/ripple levels above the maximum allowed, as it doesn’t have the required filtering coils in its secondary. Efficiency was between 65% and 74%, which will make your computer to spend more electricity than necessary (higher electricity bill). And the cable configuration is a joke, with only one SATA power connector and no video card power connector (if it had, users would fry the power supply as soon as they run a game).
This is an excellent review to understand that trying to save by buying a USD 20 power supply makes no sense.
