Real World Test System & Observations
The first setup we run is with an edge overclocked 2990WX allowing for more amperage pull from the EPS connectors. This also ensures we can pull more overall load form the supply. First up with the TITAN V in place, we observed a load of between 740-770W during workstation loading for several hours. Much to my surprise, we observed temps of 46C from the PSU at what would around 60% loading.
Next up, we added a 1080 Ti to the mix, and the load we were able to achieve was right around 970-1040W during a constant workstation loading. The workloads ran and did not see a single hiccup or output failure indicative of instability. The temp is now north of 50C, seeing a peak of 52 C where it bounced between 50 and 52 during loading. This is not bad but not ideal, and I know the PSU still has more in it, so we're going to turn up the wick a bit.
Here we added a TITAN RTX to the testbench, and we observed a maximum wattage draw of 1215 - 1305W. Much to my surprise, the fan being ramped held the supply to a maximum peak of 53C while most time bouncing between 50-52C. The thermal management on the Straight Power 11 Platinum is excellent as it is one of the quietest supplies I have tested to date, especially when at full load. I would have loved to push it further, but with only three GPUs worth of cables, I stopped here as the PSU has done its job for several hours and did not even break a sweat it seems.
