Nope, not bad for the cards at all. It's simply a matter of efficiency. 80Plus Platinum is pretty good, and it looks like your PSU is probably around 90% efficient at that load (not sure where you got 86% from.) 1200W * 0.9 = 1080W, which is 120W below what your PSU is rated at being able to deliver. This is perfectly fine.
If you want to save on your electric bill, you could go with a larger, 80Plus Titanium PSU (like EVGA SuperNOVA 1600 T2), which would likely only draw around 1148W from the wall under the same load (saving you 52W/hr.)
This may also be important if there are other things on the circuit you are plugged into. I'm assuming this is a standard 20A circuit, and you need to stay below 80% load on the circuit for safety. Further assuming you're on 120V power, this means you should draw no more than 1920W total on this circuit. If the computer alone is drawing 1200W, that leaves you with only 720W for other things. So like, don't turn on the microwave
A larger, more efficient PSU would give you a bit more headroom on the circuit for other devices.
