i think hipro was the brand in my first modern computer (back in '98), which died on me. i doubt that it has dual +12V rails. i think the corsair vx450 is a good value psu for ~$60-70 if you're looking to get one. as to whether your current one will work, why don't you try it out? you'll find out soon enough if it does or doesn't. but in the long run, you're probably better off getting a new psu.
