Should You Upgrade Your Power Supply When Buying Next-Gen GPUs?

When upgrading to modern graphics cards (like RTX 4080 Super or RX 7900 XTX), evaluate your power supply: 1) Native 12V-2x6 Cables: Modern Nvidia GPUs use the 16-pin power connector. ATX 3.0 PSUs include a native 12V-2x6 cable, eliminating bulky 3x8-pin adapters. 2) Transient Power Spikes: Older 650W PSUs may trip OPP protection when a 350W GPU spikes to 550W for milliseconds. Upgrading to a 750W-850W ATX 3.0 Gold PSU guarantees clean power delivery and safety.
