Efficiency Chart

For the most part, between 140W and 650W loads the PSU offers higher than 90% efficiency. This is definitely one of the good 80 PLUS Gold PSUs, achieving close to Platinum-level performance.

Infrared Images

Toward the end of the cross-load tests, we took some photos of the PSU with our modified FLIR E4 camera that delivers 320x240 IR resolution (76,800 pixels).

The temperatures inside are pretty low considering the operational conditions. The 120mm fan pushes enough air volume at full speed and with enough static pressure to cool down the parts that get hot under taxing loads.
