Testing completed.
I dunno if I will put it on my website, but I think I give it thumbs up for most enthusiasts:
65w i7, 16GB RAM, 2.5" SSD, 120mm Scythe 1900, Zalman CNP2sX, and a EVGA 1060 Mini SC running on a 160XT + the Adaptec 192w 16A adapter.
System actually held stable in Furmark due to heat increased resistance at 217w. I was surprised it held out as long as it did.
I switched over to Crysis 3 to get some CPU time in and as expected wattage pull was higher, capping at 220. 220 is higher than I like to see on the Adaptec brick (which is rated for 192w) but not absurdly over capacity--just at it.
All other titles I actually enjoy playing were under 200w. No issues, but to avoid wear and tear and any future crashes I decided to lower the power draw.
TWO SOLUTIONS
1. Undervolt the CPU
2. Power Limit the GPU
Option one is the way to go, if I had a K series chip. Since this rig doesn't I didn't want to put in the hours to get it there, so I decided to use MSI afterburner. I was actually surprised...I pulled back clock by 100 and mem by 80, and dropped power cap -20%. Totally stable in Furmark, Crysis 3 and Overwatch (which I actually like to play for long periods of time). Was able to end with power cap -15% and zero changes to mem or core clock. This brought my power consumption down well under 200w (165W in Overwatch) and the day was saved.
I'm pretty happy with this combo.
