Measure the voltage between the yellow and black, should be ~12VDC. The voltage between the red and black should be ~5VDC. I'm not sure what the tolerances are for your drives, maybe it's on their website. As a rule of thumb, I'd not let the 12V get below 11.9V or above 12.1V (about 10%). The 5V should be above 4.8V and below 5.1V. These are guidelines. The last time I opened a PC power supply the 12 and 5 volt supplies were not independently adjustable. Your BIOS may also tell you these voltages, along with various temperatures. lm_sensors might work as well. Bob...
