Bought myself a new video card for my computer, and now on the back of my video card box it says needs 400 watts or more to run this video card. Some IT guy on here saw my specs i told him about and said this card would work for my computer. I think my watts thing says 80 watts 200 is maximum watts...
You have a some options:
1) Try it. Install the card and see if it works.
2) Install a larger power supply, at least 400W. I would get a brand name like Antec or Corsair that has at least 550W.
3) Return the card you have and find one that will run on a 200W power supply.
I think it would be a good idea to replace the psu since being stuck with a 200w psu is going to severly limit the video card options that it presents. I would go for a 500w psu so you would have some spare room.
These guys are right and they know what they are talking about. My question is, what type of a computer do you have? The question you should your ask yourself is how much money you are going to stick into this computer?
Already you have a power suppy problem. We don't know what your CPU is or how much ram and what windows version you are running? There could be a lot of problems and is it worth it?
Lets say you get a good PSU and your GPU but if you have a shotty CPU then you will have bottlenecking problems. That is just an example. Then you will be buying a new CPU and what if your mother board won't support certian hardware. All this is food for thought
