Does an HDMI TV hooked up to my PC effect my PSU?

Will it draw power from my PSU or just the outlet that the TV's plugged into? It's a 46" Samsung HDMI TV and I'm going to be plugging it into a Radeon HD 6570. The TV is at 1920 x 1080 60Hz.

the TV draws it's own power from it's internal power supply, as does the computer. The computer will draw more power from the wall when the video card is being pushed to it's limits

Will it be a huge amount? I have a decent 300 watt PSU, and without the video card, I'm using 231 watts (according to Newegg's PSU calc). The video card has a max tdp of 44 watts, so with 275watts MAX, I'm good to go, right?

Well, if you have issues, you know your power supply isn't up to the task. However, you might actually risk ruining other components in the computer if the unit is not a decent one, for example, and explodes.

Newegg's PSU calc gives the DVD-RW 40 watts of power, but I'm assuming that's if it's being used. I'm most likely going to disconnect it. Plus, I might just drop down to a 6450 to be on the safe side which has a max tdp of around 20 watts, with a grand total of 213 watts MAX. I'm sure I'll still be able to play minecraft and less demanding games like TF2 and hopefully Left 4 Dead 2.
