did lots of online/ in store research but can't locate a low profile pcie video card with compatible power supply specs 250-280 Watts for slimline dell pc. could also use pci low profile video card with same power supply specs . all the video cards i've checked out require min. 300W. Where can I find one w/in 250-280W? Tried dell, they have the replacement part, but, because it's so "rare" they want $219. urrrrrrrrrgh! also, is the watt requirement that critical? tech support person i'm using thinks i need the new card because i can't get a display screen on my monitor ie. originally intermittant screen w/ error message:"cannot display this video mode"., now completely gone screen. no usual usgage. any suggestions, thx!
