SilverStone Strider Gold 650 W Power Supply Review
Voltage Regulation Tests
Contents
The ATX12V specification states that positive voltages must be within 5% of their nominal values, and negative voltages must be within 10% of their nominal values. We consider a power supply as “flawless” if it shows voltages within 3% of its nominal values. In the table below, you can see the power supply voltages during our tests and, in the following table, the deviation, in percentage, of their nominal values.
The SilverStone Strider Gold 650 W presented outstanding voltage regulation, as you can see below, except for the -12 V output during tests one and two (this output was still inside the allowed range, though).
