I recently bought a new GeForce GTX 780 FTW Graphics Card and I am worrying about my wattage.

I have a Bronze 750 watt PSU.

Here is the GPU

And lastly, the CPU is Intel Core i5-2500 Quad-Core Processor 3.3 GHz

I'm assuming that these hardware 2 hardware parts use up the most wattage and If I am mistaken, please ask me to post more components.

    Well, as far as wattage is concerned you are fine. However, as far as quality of PSU, you are not. The quality tiered list I generally go by has that PSU listed as the worst quality. You have a nice setup, I would replace that PSU ASAP! Right now isn't a great time for deals, but for 80 dollars you can get one that I would trust with that system: Ideally you could find a better price when better sales are going on, but honestly, you need to replace that PSU now.

    I literally just finished working on a friends Pc that had a crap Psu installed. It made a zzzt, pop noise and fried the Psu. Luckily her other parts are fine(with the possible exception of the video card) and I got it booted up with a spare 300w Psu i had laying around running off on-board video from the motherboard. When bad psu's go, they can take your system with it. Burning out the motherboard, cpu, ram and video card.
  3. I had no idea my PSU was that bad. Damn. Well thank you, my next purchase will be a new one of those. As for my question about the 780 GTX, thank you very much. :D
