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 regulation deviations in each of the charts below are calculated by taking the nominal values of the rails (12V, 5V and 3.3V) as point zero.
Load Regulation Charts
The ST60F-TI is clearly super efficient. With higher than 55W loads, efficiency is within the 90-95% range.
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 temperatures inside of SilverStone's ST60F-TI remain low, despite the prolonged full load operation during the last part of our cross-load tests.
I recently purchased a 800w Version(these are the only Titanium PSUs in the Australian Market under 1000w) and its been everything i've wanted, running at almost 50% load it gives me its peak efficiency which is exactly why i paid the premium to get a Titanium PSU.
I can see the 600w version being a more commonly purchased unit with the way power consumption has dropped, Skylake Rigs only use around 300w(give or take variables) which would be the Striders peak efficiency.
What I don't understand is the small transformer. Aris, you mentioned that this unit, to have higher efficiency, switches to not-as-high of a frequency (which also affects transient response negatively). Since transformer size is inversely proportional to the AC frequency, wouldn't the transformer have to be larger? Is there any downside to a smaller transformer?
Yet again, more PWR_OK cheaters. It seems like at least one in two PSUs are like this. I agree that no power switch on this unit seems very silly to me.
