I power lift for fun and compete in Tough Mudder, Spartan Race, Crossfit..
Ive never tried to max out but I've done 3 reps of each:
Dead Lift 315
Back Squat 275
OverHead Squat 155
I'm 31 170lbs 5'10"
Trying to get more serious about it. I do 4 sets of 8 - 12 reps. I run a lot, which I think draws back my absolute strenght (I consistantly finish 3 miles in 18 minutes). Fun as hell, love it.
