Cross-Load Tests And Infrared Images
Our cross-load tests are described in detail here.
Load Regulation Charts
Efficiency Chart
Efficiency falls between 92 to 94 percent in the 200 W to 1000 W region, even with a high load on the minor rails. We would like to see greater-than 90% readings above 1.2 kW loads, though. Moreover, our equipment didn't record over 94% efficiency with any load combination, something we'd expect to see from a Titanium-class 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).
The modular cables' temperatures warm up due to the current passing through them. On the contrary, the temperatures of various parts inside the TPG-1500D-T are rather low, given the huge power levels they handle. The high-speed fan, combined with an aggressive profile under tough conditions, doesn't let the internal temperature spike. No doubt that plays a key role in extending this power supply's reliability over time.
