Which of these PSU is the better one.

Solution
The Cooler Master eXtreme Power Plus 500W (RS-500-PCAR-A3 / RS-500-PCAP-A3) is a piece of trash. It is an old low end design. The DC Output Quality was outside of specification limits at full load on ALL of the rails. The unit’s component selection and build quality are far from top notch.

The Thermaltake Litepower 500W - W0316 is another piece of trash. The 500 Watts printed on its label is 500 Watts peak power. Its continuous power rating is 400 Watts. Its maximum combined +12 Volt current rating is 23 Amps.
