Need some help

[DanB]

Finishing up on my I3v and I tried to wire in the power supply using an antec vp450 and nothing happened when I turned it on? Could it be possible that I crossed some wires after I snipped the tips off? This could be either yellows or blacks. I don't think I did but it's the only thing I can think of. If this is the case how do I tell which goes to which? Thanks

Hi Dan,

Google "modifying a power supply for 3d printer". There is a green wire that must be shorted to ground in order for the supply to work. Plenty of web pages and youtube videos will help you with this. Here is the link from the RepRap wiki - http://reprap.org/wiki/PCPowerSupply

Cheers,

I need to do this. Except, I would have 3 or 4 black plugs in a column. I don't want just one ground plug. And I would have the outputs ordered differently. I would have them go -12, -5, Ground, +5, +12.

When I worked on the PSU for my printer, I knew that I would only need 12V and ground, so I didn't bother with the other voltages. I just have two plugs - one for +12V and one for Ground.
