Hi all,
I've recently completed my first RepRap (or at least completed to the stage where basic objects print nicely).
For my power supply I used a standard ATX supply rated at 450 Watts. My RepRap is a Prusa i3 with a MK2 heatbed.
The power supply I'm using has a blue LED and fan built into the bottom of it. I've noticed when the heatbed and hotend are both on at the same time, the power supply starts groaning ever so slightly, and the blue light inside it has a noticeable flicker.
I've not yet added a 5v load to the power supply, as I'm currently awaiting some molex parts. My plan is to run a Raspberry Pi + Camera, and some LED light bars from it as the 5v load.
Am I right in thinking that the seemingly unstable power I'm seeing at the moment is due to there not being a load on the 5v rail?
Just wanted to make sure it wasn't an obvious sign of imminent failure or something before I go ahead and carry on working on it!
Many thanks :)
