I purchased my brick from "IT Wholesalers" on Newegg. It looks 100% legitimate but it could be fake. Model DA330PM111.
I've turned off Turbo on my 7700k and have only had it cut off once in about 5-6 hours of gaming. Obviously I want to be able to have turbo enabled but it's a compromise for now. I've had it hooked up to a Killawatt and got it to read 310 Watts running Unigine Valley + Cinebench concurrently (with turbo off). Not sure how to observe for spikes above that. I did notice however that using other benchmarks throttles either the CPU or GPU utilization and I'm unable to get more than like 270 Watts pulled from the wall. I may just buy a new brick from dell directly even though it'll run me $160.
Side note, I noticed the little plug that accepts the DC Jack from the Dell brick gets extremely hot. I don't have a way to measure its actual temp but I'm concerned it may get damaged from extended use at high power consumption.
