ATX power supply

[RoMZERO]

Dear all,
I want to use a old ATX as power supply for the RPi.
My old ATX has a 5v (30A) output. Is this output safe for my the RPi or is there the risk to damage the hardware?

Thank you in advance.

Best regards,
Roberto

Did it damage the CPU, motherboard, or drives of the PC it was powering before? If not it's safe to use. You may want to include some fusing, 30A could be a significant short circuit. The RPi can't draw any more than it's fuse will allow, but the power wiring between the PS and the RPi could benefit from a little current limiting, just in case.

An ATX power supply can be used. No problem if you power the RPi through the micro USB port. If powered through the GPIO port then I would add a fuse (2A).
You might consider using the ATX Standby 5V 2A on the purple wire (pin 9 on the 24 pin connector). SB is always on even when the main power supply is switched off so no annoying fan noise.
