Your 5V rail is sagging. You're running a cluster of boards, a long LED strip, or a motor driver and the little USB adapter can't keep up. This Mean Well 70W unit puts out a solid 14A at 5V DC. That's enough headroom to keep voltage stable under load without thermal shutdown or brownout. Mean Well supplies are the ones you find in Australian factories, test labs, and maker workshops for a reason – they don't drift. At $23 against a $65.40 RRP, it's the no-brainer upgrade from a wall wart
