Load Regulation Charts

Efficiency Chart

Efficiency falls within 90%-95% for much of this unit's operational range. With more than 110W load at +12V and all the way up to full load, efficiency is very high. This is hands-down a true Gold-rated PSU.

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).

Even under harsh ambient conditions and a full load, this PSU doesn't sweat. Its internal temperatures remain modest. This is especially noteworthy since the compact chassis is so tightly packed. Obviously, high efficiency is to thank for such little waste heat.
