Balancing ATX Supplies
Revision as of 20:41, 3 December 2011 by Bryanandaimee (talk | contribs)
A modern high power ATX supply off a PC is a good way to power your RepRap but requires a bit more care than a purpose built 12V supply. The main issue with these supplies is the requirement for a load on the 5V line. To get reliable opperation you will need to balance the loads on the 12V vs the 5V lines.
| 12 V Load (Amps) | 5 V Load (Amps) | 12 V Voltage | 5 V Voltage | |
|---|---|---|---|---|
| 4 | 0.5 | 11.87 | 5.18 | |
| 6 | 0.5 | 11.77 | 5.2 | |
| 16 | 0.5 | 10.98 | 5.31 | |
| 16 | 3 | 11.46 | 5.23 | |
| 16 | 5.5 | 11.77 | 5.19 | |
| 16 | 8 | 11.94 | 5.15 |
