Do you consider any 512MB graphics card to be 'high end'? If not, what parameters are you referring to that qualify a card to be 'high end'? I suppose the other most logical question would be what are the most powerful cards this level of power supply can handle? I'm not a gamer nor do I usually, if ever, use any other heavy graphics.just a web surfer primarily. Then only question remaining is about your comment that a 300W power supply isn't usually sufficient for 'high end' cards. I never thought to look there although I use it quite regularly. Thanks for the Wikipedia reference about PCI Express x16 (and v2.0). Motherboard manufacturer's name: ASUS ABM2N-LA Here are some motherboard specs (that I forgot I had put away in a file): Just returned from an extended break for dinner and watching some March Madness. Unfortunately I've found that most cards specs (at least those posted by the vendors) do not tell you the power supply requirements, so I don't know how they expect you to guard against wasting time and money when ordering insufficient or incompatible products.Ĭlick to expand. I haven't seen any info, data, specs or whatever to tell me whether my power supply is PCI express x16 compliant, but since it came from an HP computer with a motherboard with a PCI express x16 available slot, I'd say I'm probably good to go in that respect. I also noticed that one of the cards I was perusing said to make sure the power supply was 300W and 'PCI express x16 compliant'.

The individual who installed the HP motherboard for me also had to install that same (older HP) system's 300W power supply because there was some kind of proprietary connection necessary for the HP motherboard that my existing 430W Thermaltake power supply didn't possess.
