Hello, everyone... I'm here to try and assist. I thought I had everything figured out, but... I'm not sure. I purchased a used Lenovo P500 and planned to upgrade it fully. I considered getting a gaming X99 MB, but opted for the older workstation design instead. I ordered a 650-watt proprietary power supply to replace the 490-watt stock unit. The original PS had a 6-pin PCIe connector, but I acquired a custom dual-drop adapter that converts it to 6+2 and 6-pin PCIe. The new PS was ready for installation, but I connected it to the old adapter which only had 6 pins. When I tested it with an RX480, the PS refused to power up, which I suspected would cause it to overload and shut down. Unfortunately, it did—my motherboard was damaged. I checked the cable connections with a multimeter and everything looked fine. The BIOS had overload warnings enabled, which I thought might have triggered the boot issue. I tried flashing the BIOS, but it kept power cycling and showing an amber warning light. Anyone have thoughts on whether a new motherboard with the correct PSU would prevent this? Also, does the BIOS have settings for overload protection that could have prevented it?
