Intel talks all things ATX 3.0, PCIe 5.0 GPU connectors, and why you might need a new PSU.

IIRC the EPS12V connectors have compatible pinouts compared to ATX12V. The 24-pin connector has the same pinout on 20 pins as the ATX 20-pin connector, then it has an additional 4 pins on one end.

ATX 24-pin Power Connector The 24-pin ATX Power connector is probably one of the most important connectors on the motherboard.

Silverstone new Hela 2500Rz flagship PSU comes with quad 16-pin 12V-2x6 power connectors, and more than enough power to run four (or more) graphics cards simultaneously.

Intel’s ATX12VO power supply standard will help desktop PCs meet increasingly stringent government standards on idle power consumption. We take a closer look.

The power boost comes courtesy of an integrated 8-pin PCIe power connector on the motherboard itself. Conceptually, it's a little like the supplemental power connectors that already feed power to ...

TL;DR: NVIDIA's RTX 5090 graphics card requires 4 x 8-pin connectors for 600W power officially, but can operate with 3 x 8-pin connectors at 450W, seemingly running only 5% slower in 4K benchmarks ...

Diverging from the standard, this design incorporates dual regular 8-pin PCIe power connectors, as opposed to the more commonly used 12VHPWR power connector.

Home > Computing MSI X870 Boards for AMD CPUs to Offer 8-Pin Auxiliary PCIe Power It says it's for 'AI Computing' or systems with multiple GPUs.

The new GALAX HOF GF1300 power supply is a next-gen ATX 3.0-ready PSU with not one, but two 16-pin '12VHPWR' power connectors, ready for your RTX 4090s.

PCI standards group deflects, assigns blame for melting GPU power connectors "Members are responsible for safety testing of their products." ...

This change allowed for more room on the PCB, as it went from dual 8-pin connectors on high-end cards to a single 12-pin, mounted vertically.
