Efficient power for a midrange machine

At 600W, the Amacrox Free Earth 88PLUS PSU will handle the load generated by the majority of single GPU systems, and with an 80+ Silver rating you can expect a lower power bill than with less efficient choices. In the testing that Hardware Secrets performed they saw the claimed efficiency until the load crested 86% which saw that number decline to 84.9% efficiency at 99% load, a scenario that should not often happen under normal usage; if you pull that much power you need a PSU with more wattage.
