Hello everyone. I am currently planning to purchase a GTX 780 to replace my good old GTS250. Other specs include an i7 870(or 920 can't remember ), 6GB RAM (3x2gb), X58 motherboard and 2TB HDD. As it is more than troublesome to unplug all the wires and take it out of the desk, I couldn't check what is the power of the PSU. After my research on the HP product list, I believe it is somewhere between 450W to 500W. Do I need to replace a PSU if I am to replace my GTS 250 with GTX 780?
Thanks
