Hello I need to buy a new graphics card but my current psu is not strong enough to buy the one I want. I was looking to see if my current psu is the same size as the one I am looking to buy and will run in my computer. Here is the link to the one I want to buy:http://www.tigerdirect.ca/applications/SearchTools/item.... And here is the model number of my current one: PS-5301 HA. If the psu I want to buy will not fit could you please recommend some that will. Thanks!
