I have a prebuilt HP PC that has a Ryzen 5 3400 G Mobile with Radeon Vega Graphics. There is a spot on my motherboard where I can install another GPU. However, my PSU is only 180W and I can't upgrade it to a 300W - 400W PSU because there is nowhere for me to put the 20 - 24pin connector because there is not a 20 -24 pin spot anywhere on my motherboard. Are there any low profile GPU's that a 180W PSU can support?
