Hey everyone I just recently built a low end rig and I just now ordered the video card but am affraid my PSU wont provide sufficient power to the card.

At visionteks website its minimum requirement is a 450w PSU an mine is only 430w thermaltake on a single rail my question is would it hold up without straining the PSU and components?

Thanks in advance

You need more than that PSU can offer unfortunately, although a good one can cost less than $50!
