Sorry in advance for stupidity guys.

Right now, I have a shitty 800W Power supply running my rig. But I would like to upgrade my graphics card to a GTX 770, I just don't know if I will need to upgrade my psu, I don't really understand how to use the PSU Calculators. So even if someone can run me through one of them, it'd be great.

What rig, what PSU, make and model.

Aside from shitty PSU quality (which is never a good idea) 800W seems like overkill to any build unless you have 2 GPU's and a shitload of other PCIe-slots filled.

Your motherboard ? But 600/650W of a quality PSU is more then you'll ever need.

With that motherboard and components I added 2 GTX 770's, 4 RAM sticks, 3 USB devices, a modem, fan controller and 5 extra fans in a calculator and ended up with 561W recommended PSU under 90% load.
If you only use 1 GTX 770 you will only need 427W for PSU

So you'll be fine with your 800W PSU. Even though it's shit it means it's efficiency will run at 75-80% which is still 600-640W so you're more than safe! Remember these calculators always add a couple of percentages up for recommmended settings and in reality you won't be running your PC at 90% load anyway so no worries and just upgrade to 1 or 2 GTX 770's.
