We know that testing a power supply on a loaded system is not the very best way to do so, but you can not overlook real world testing. Other sites have methods that use thousands of dollars in equipment to provide them greater detail. We have a trusty digital multi-meter. Those sites and the methods they use should be the true means of determining how good a power supply really is; however, we feel that showing you how it performs under real world conditions is also a valid measure of its performance.


As you can see, the HCG is able to easily handle the load we were dishing out. The idle numbers are right where one expects them to be, sitting at 12.1V on all four of the 12V rails, 5.09V for the 5V rail and 3.36V on the 3.3V rail. Under loaded conditions those voltages only drop ever so slightly, down to 12.0V, 5.08V and 3.33; respectfully. These readings are well with in the ±5% tolerance that is allowed, as per the ATX PSU specifications.
