Load testing will go the same way it did on the 1kW model, except we’re only going to 850 watts today. Both SM-268s will be used, but the second one will only be helping out with the full power loads only. One is technically enough, but these load testers are getting old and I like to go easy on them when I can.
Naturally, we’ll start with the standby load tests.

The 1kW model really stood out here for efficiency, and I am pleased to report this unit continues the trend. We are well over the 80% mark on all three tests, and this is definitely something I want to see more of moving forward from other high-end units.
Voltage stability is an excellent 1%.
Now, let’s run the main tests; keeping in mind that my methodology does require us to get the actual 10% load test numbers from Ecova’s site. I’ve found that it’s the only way for many of these units to actually clear Titanium. Since they don’t have any Titanium units from EVGA listed there yet, I’ll have to use the Super Flower load numbers instead (as I did with the 1kW model) and hope this unit passes. It should… big brother did.

And yes sir, we do pass Titanium. I need to give it a little bit of leeway on test three, as is often the case with Titanium, but I have no problem allowing up to 1% and the unit is well within that.
Of course, one major benefit to being at this absurdly high level of efficiency is that these things put out less heat. As a result, the fan controller waited and waited and waited. Finally, about two minutes into test five, the fan controller gave it some thought and decided to kick the fan on. It was then quick to shut the fan off again in test CL1. That’s really impressive. Keep this thing under 25 degrees, and you may hardly ever see the fan come on depending on how much load you run with it.
Now… you may remember that the bigger T2 model being so impressive that I decided to add a new “mythic” level of voltage regulation to the scoring methodology. Let’s find out where this unit lands on that scale. I get 0.9% load regulation on the 3.3V rail, 0.8% on the 5V rail, and 0.5% on the 12V rail. That gives us an average of 0.73%. Provided the unit repeats these results in the hot box, that’s actually a little worse than the 1kW model did so we’re in the excellent range right now, not mythic. I need to see an average above 0.50% to give it that level of scoring, and yes I do need it to clear two decimal places to get there.
But things could change in the hot box. This bad boy might tighten up some. Let’s turn the page and find out.
