I will be building an external hard drive setup for my computer very soon. I am in the market for a case with a power supply to house the drive(s). What I need to know is how large must the capacity of my power supply be? I wish to house and power four half-height drives eventually. The drive I will install first is the Seagate ST-296N SCSI 80MB. Thanks in advance for any help you may offer! Jim Bernatowicz (jbernat@andy.bgsu.edu)

Remember to shield the power-supply with metal and use thick enough cables. Fan won't be bad either. I think you'll need something over 150W. Four drives at startup draw quite a large amount of amperes out of the power. If you put some kind of a delay to power them up one at a time, smaller power would be enough. 150W powers are quite expensive!

Looking in PC WEEK, one sees 230W power supplies for ~$55 US. PC cases are also lots cheaper than special disk cases, and have places in them for power supply, several disks, etc. You might even get a better deal if you buy case & power supply at once. van = vsnyder@jato.jpl.nasa.gov -- vsnyder@jato.Jpl.Nasa.Gov ames!elroy!jato!vsnyder vsnyder@jato.uucp
