NerdRalph’s story on upgrading GPU capabilities without using all new hardware.
My old card had two 6-pin connectors, which I had plugged a 1-2 18AWG splitter cable into. That was connected to a 16AWG PCIe power cable, which is good for about 200W at a drop of under 0.1V. My new card with the single 8-pin connector wouldn’t power up with just a 6-pin plug installed. Using my multi-meter to test for continuity between the pins, I realized that it’s not just a row of 12V pins and a row of ground pins.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
