As a general rule, pin connectors get about 1A per pin max. Looks like you're drawing more than that. If you've got a good multimeter, it'd be worth hooking it up to measure the current when you're printing.by nemo000111 - Reprappers
I ended up buying one of these: Meanwell 12v 320A power supply Decided to spend a little more than on the Chinese knockoffs as who knows what the ripple on them is and I've had psu's take entire systems with them.by nemo000111 - Reprappers

Hi all, I know this has been talked about to dead, however I can't find a good arguement either way. Do I go with a pc power suppy or a no-name 12v 30a 320w supply (like this example supply). This is for my first printer (prusa i3, 5x nema 17 motors, ramps 1.4, and pcb heatbed). I need to buy the supply as I don't have any spare of either type around.
