Do I have to upgrade my power supply? I'm tight on money.

It can run at 300W..http://cgi.ebay.com/LiteOn-PC-Power-Supply-300-Watts-PS-6301-08A_W0QQitemZ220257688602QQcmdZViewItem?IMSfp=TL0807161598r36120

Will this hold up?

so you have a Acer desktop. Nope you need a upgrade. Depending on which card you choose you'll need at least 500w psu with decent 12v amps and a PCI-e connector.ShimmerMan
