At 220w i dont think the power supply has quality...
wattage is not a measure of quality .
So long as its an 80+ bronze unit it may well be fine . It seems to be in a compact case since the OP is asking about a half height card so I suspect its an oem computer where they have sensibly not gone overboard on the psu because expansion options are very limited
From memory the graphics card will pull only about 26 watts maximum , but according to this the TDP of the card is a shade over 19 watts http://www.anandtech.com/show/2931
Your pentium will be around 60 watts , so unless you have 23 hard drives connected OR the power supply is absolute junk , you should be fine
