ElmorLabs PMD2X Features Per-Wire 12v-2×6 Monitoring With Overcurrent Alarm
The ElmorLabs Power Management Device 2 (PMD2) is a discrete power management device that allows tinkerers and hardcore overclockers to monitor their system at a hardware level and on a per-device basis. The latest update to the PMD2 is the PMD2X, which adds per-wire current, power, and voltage monitoring to the device's 12v-2×6 and 12VHPWR monitoring. The product's software component now also allows users to set up an audible alarm when individual wires exceed maximum thresholds, effectively allowing it to fulfil the role of something like a Cooler Master GPU shield.
In addition to the new audio alarm and granular GPU power connector monitoring, the PMD2X also features compatibility with Seeed Studio XIAO boards, allowing for wireless connectivity, although this will require more than a little additional work to set up. This effectively turns the ElmorLabs PMD2X into a safety tool that can be used in a daily driver capacity as well as for the hardcore overclocking and tinkering that it was originally designed for. The ElmorLabs PMD2X is available for $109 on the ElmorLabs official store.

Fools & money
- Current max error +/- 0.5 A (@ 10 A)
i would have expected +/- 0.5 mA and not 500mAno word about if those min, max, average, etc. to give reasonable measurement results
when i want random numbers (mostly invalid measuirement results) i can use a screensaver on my secondary screen.
The microcontroller is not the problem, it's whatever method they choose for the current sensing. It's good enough for the application but for what they're charging you'd expect better than 5% error.
