I have to say that I very much doubt it. According to AMD here AMD Radeon
, they recommend a minimum PSU rating of 400W for this card. Your PSU of just 220W is not going to cut the mustard here, and I would suspect that it is very much near its capacity with what you currently have on this computer. Certainly, if you are currently using on-board graphics, then factoring in a graphics card to the equation is likely to cause system failure due to the overloading of the PSU.
