based on your posts, my guess is that you do not have the knowledge required to rewire the z800's power supply outputs using a ATX supply 

 

either have the existing supply repaired or replaced as "SDH" has previously recommended, or buy a premade adapter that converts the non z800 non standard 18 pin to work with a ATX supply going this route requires a "EATX style" case to hold the z800 motherboard which is not cheap

 

attempting to make a z800 pwr adapter yourself is not a beginner's project and also keep in mind if using a adapter, the ATX supply must be a single rail design 1000 watt or better which will cost about the same as replacing the existing z800 supply with a working replacement
