Good thing I asked then. Do you think you could elaborate a little more on this because again I'm pretty inexperienced when it comes to hardware and I wouldn't know how to pick an entry level card from a mid to high end except by looking at the price?Your Compaq only has a 250 watt power supply so the only graphics cards that will run are entry level cards that don't require their own power source. Mid to high end Pci-e cards require alot more power than your power supply can provide.
Thanks for the information.Your Compaq has a 250 watt power supply. So you can not use a power supply that states it needs a 500w PSU. For your system , to throw out an example, I would suggest an nvidia 8400gs or similar. They ask for a 300w power supply but your 250w PSU should get away with it.
So laymans terms, you can not run a GTX 680, you can only run an old GFX card that does not require much power. Dunno how else it can be said. Don't quote me that the 8400gs will definately work either for that matter
I don't plan on using an upgraded graphics card. I just don't know how I'm supposed to find an appropriate card. Everyone says I'm supposed to look for a low tier one, which I get, but I don't understand how I can designate a particular card as low tier. Will it say on the box what type of power supply it's compatible with, and if so, is that all I need to know?I hope you don't build computers for anyone else but yourself because it most certainly does matter. Do you honestly think a 250 watt power supply can power any graphics card out there? To the poster: your computer is an OEM computer and pretty much all OEM manufacturers use low quality power supplies that are just enough to run what they came with. Mid to high end cards require a Pci-e power plug to run them and they are dependant on the volts the +12v rail puts out. Your power supply does not have these connectors. Look at your power supply and check the +12v rail and I'm sure it's going to be low. The only card I would ever recommend you or anyone with your system runs is a lower tier graphics card that gets its power from the Pci-e slot on the motherboard which produces a maximum of 75 watts. What do you plan on doing with an upgraded graphics card?
