I have a Dell PowerEdge SC420
I looked on the PS unit and it has:
MODEL NO: PS-6311-1DFS
DC OUTPUT 305W
+5V === / 22A MAX
+5V(FD) === / 2A MAX
+12V - A === / 18A MAX
-12V === / 1A MAX
+3.3 === / 17A MAX
+12V - B === / 18A MAX
COMBINED POWER ON +3.3V AND +5V NOT EXCEED 150W
COMBINED POWER ON +12V-A AND 12V-B NOT EXCEED 264W
MAX. CONTINUOUS TOTAL DC OUTPUT POWER SHALL NOT EXCEED 305W

I looked at the hard drives and they are:
Seagate: (I have 4 of these)
+5V 0.75A
+12V 0.35A
Maxtor: (I have 6 of these)
+5V 740mA
+12 1500mA
Leading out of PS:
cord with: 2 SATA power connectors
cord with: 1 PATA and 1 for floppy drive
cord with: 1 power connector w. 6 sockets (5 have connectors inside) and 2 PATA power connectors
I also placed 3 PCI IDE expansion cards in the server.
My question is - what is the proper way to do the math to find out the maximum number of hard drives that the PS can support?
And do you think it is safe to plug all of those 10 hard drives that I have?
Thank you all very much...
