Good day,

My sister asked me about graphics card update options for her OptiPlex 9020, and I saw this GT-710 that would fit her needs of playing flash player games. My question is, would I need to provide a new psu? or it will be fine just plug and play? 

Edit: I read that graphics card under 75w will be fine, so in that case would a GT-1030 be compatible as well?
