Cross-Load Tests And Infrared Images
Our cross-load tests are described in detail here.
To generate the following charts, we set our loaders to auto mode through our custom-made software before trying more than 25,000 possible load combinations with the +12V, 5V and 3.3V rails. The load regulation deviations in each of the charts below were calculated by taking the nominal values of the rails (12 V, 5 V and 3.3 V) as point zero.
Load Regulation Charts
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.
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.
Also those cables - the word "eyesore" comes to mind! I would be replacing those with some custom ones ASAP! :ouch:
Yeah it's just a crap unit which is hoping the kids orgasm over those RGB lighting, it's doing my head in but I'm sure it'll soon become mainstream then die.
Only at the TPG-1250D-T they used the new & excellent CST platform by CWT.
For all the other wattage models so far, ( 850 & 1500watt ) they used mediocre platforms by Enhance.
I had high expectations for Tt's new line of PSUs, but they were proven futile.
Also, I love the pixelated 8-bit-ish thing you've got going on with the ripple graphs on page 9. Perhaps
Otherwise, this was pretty much as expected. A useless product (the world does not need more 1000W+ PSUs), with useless features (RGB in a place where it'll be invisible in 90+% of modern cases), at a useless price point. That it performs badly as well just adds icing to the turd.
