So, unfortunately, I have an HP Slimline S5120F PC which only has a 220W PSU in it. I just have a simple question, do you think my PC can handle a Gefore GT240 card? I heard it uses a very small amount of watts, about 70 tops. I also heard there are some sort of PSU Calculators on the web, but for some reason none of them work for any of the browsers on my PC, if anyone is bored out of there minds and feels like helping me out they could always find one and test it with my specs with and without the card...I would be very grateful! Anyways, the specs are: Processor: AMD Athlon X2 7750 2.7GHz Memory: 4GB DDR2 800 Hard Drive: 500GB 7200RPM SATA Optical Drive: SuperMulti DVD Burner with LightScribe Technology Graphics: NVIDIA GeForce 6150 SE Audio: Integrated audio, 6 speaker configurable Ethernet: 10/100Base-T network interface Thanks in advance for the help! Suprgamr232 I was also thinking about possibly just getting a new case and PSU for it instead, anyone have any suggestions or could show me a good tutorial on the easiest way to do this?
