Voltage and Clock Speeds
On the power supply there is a specifications label. It should be there, it's required by law. The model will be shown on the label, usually on one of the four sides. Occasionally, you might need to take off the four screws securing it to the back of the case and turn the power supply to view the label.
I can tell from the label that it's a Cooler Master product with a 600 rating. The specifications mention an 80 PLUS Standard certification.
