Where can I get these at? I burned out the stock 200w power supply for my compaq. I'm surprised it lasted this long. It was being asked to do way more than its rating for WAY too long. Are there good third party replacements? I look online and i think I can find 300watt presario PS's but not sure if they are compatible. Its almost like they dont make anything bigger than 200 watt for this computer. Like I said BING search comes up non-conclusive. Does anyone out there have a bit of experience on where good replacement Compaq power supplies can be gotten for a decent price?
