Igor's Lab has conducted an in-depth exploration of the power management system of the latest NVIDIA GeForce RTX 5090 graphics card, specifically examining its peak power consumption in adherence to the ATX 3.1 specification. This detailed analysis is particularly pertinent for users who are still utilizing older ATX v2.51 power supply units (PSUs) and intend to connect the graphics card via the included adapter (designed to convert four 8-pin PCIe connectors to 12V2x6 connectors).
