What is the most realistic power cap for Extreme 1650 LP overclocking shunt mod?
i don't have any idea about other simple places to solder a 6-pin connector for improved grounding and higher current handling without affecting the slot grounds.
The parts on the card are designed to handle a specific power level. Components like the VRM are limited in their capacity, and they won’t sustain much current before overheating. You could connect it in any direction, but a 1000w unit would only extract what it requires. Pushing beyond the limits of any single component—whether by amperage, voltage, or heat—will cause the card to fail instantly. The added 6-pin PCIe can boost power output by 180w, with each pin rated for 60w and 5A, across three pins. Regardless of the source, the card isn’t absorbing energy.
I resolved the issue and enhanced the card with additional grounds. I also removed the pcie slot +12v pins from the connection, ensuring only dedicated +12v from the 6-pin connector is used. This prevents any backfeeding into the motherboard, which previously caused the motherboard lights to flicker briefly during shutdown. Now everything operates smoothly and the power limit has increased by 33%—from 66w to 90w!
