I have a HP a730n, right now I've got a Radeon 9250 pci, but I'm ready to upgrade to a pci-e. My computer only has a 300 output wattage though, and most video cards require a 350 watt minimum. Any suggestions on what card to buy, or a solution to upping my wattage?|||Well you have two options, one of them being: A new power supply with more wattage. However Wattage is not the only important thing in a power supply, you also have to look at Amps on the 12v+ rail(s) having more than one rail is a good thing, and higher end power supplies have 4, with 10-28 amps on each rail. That being said, I don't think you need a Humongous power supply just for a video card, unless you are planning on going top of the line, which would be a Nvidia Geforce 8800GTX (until ATI releases the R600 series) the G80 chips are power hungry, but if you look at www.newegg.com and look for video cards, the recommended wattage is almost always stated in the Specifications. You are looking somewhere in the 6800GT - 7600GT range as far as having only 300 watts. If you do decide to upgrade your Power supply, keep in mind that cheaper is bad, power supplies are an area people skimp on all to often, and its a volatile part of a computer that deserves to be quality, companies like: thermaltake, antec, PC power and cooling, enermax, and a few others make very good, very well rated power supplies. Hope this info helps!|||i have the same pc,the 7600gt will work on a 300watt power supply, i bought it about six months ago and it works great.
but you can buy a 500watt power supply from newegg.com for cheap and if you want the video card to last you buy a nvidia 8800
good luck
