I have a gateway fx6800-o1e that is dead . It gave a warning tone at first when trying to start for a few days. Then suddenly it started w/cmoss errors , then, next day, it died completely, no tone at all . I think it may be the PSU because I have heard the 450W unit goes bad frequently. Want to replace it w/750-650 unit . Need to know of compatible good brand to use.

You need a standard ATX power supply, get good ones (corsair for example , don't get cheap ones (similar to OEM power supplys).
