Hi, thanks for your help. I've check the voltage on the ATX-Power Connector and all measured as it should, 3.3V, 5V, and 12V. Should I change the PSU?

Without a load test you cannot tell whether the PSU is working properly.

Without a known good powersupply you cannot test the other components.

disconnect other components and leave only cpu, stick of ram, v-card (if u don't have igp), psu. If system refuse to post swap memory, swap psu, if still refuse to boot then cpu or mobo is bad, if u have another compatible system test cpu, ram, psu, v-card.
"Should i change the PSU?" YES.
