As the "heart" of the PC computer, the importance of the power supply in the computer is self-evident. It's just that the current computer power standard is still at 2003, ANDX 2.0. Although Intel launched the AT X2VO standard in 2019, there are very few products that are currently motherboards and power supplies, let alone promoted.
Recently, Intel announced a new ATX 3.0 power standard. The biggest upgrade of the new standard is to add a 12VHPWR power supply interface for graphics cards, using 12+4 pins, and the maximum power supply capacity can reach 600W, which easily meets the power supply needs of PCIe 5.0 graphics cards. Not only that, the new standard also mandates that power supplies above 450W must be equipped with a 12VHPWR interface.
In addition to forcing the 12VHPWR interface, the ATX 3.0 power supply standard brings several changes:
1. In the case of adding a 12VHPPWR graphics card power supply interface, all power cord connectors need to be marked with four power supply powers of 150W, 300W, 450W and 600W.

4, low load efficiency upgrade, 10W or 2% of the maximum nominal power, the efficiency shall not be less than 60%, the recommended is not less than 70%.
5. Increase the instantaneous power supply peak, 10% of the working cycle, 100 microseconds time, withstand 200% of the nominal power.

Relax the +12V circuit load regulation limit from -8% to +5% for PCIe interfaces and -7% to +5% for other interfaces.
7. Adjust the power On power signal speed to speed up the response and system wake-up.
8. Added Alternative Low Power Mode/ALPM.
9. The power supply label must include T1 and T3 timing.

Editor's comments: Previously, ASUS, Cool Cold, Gigabyte, MSI and other manufacturers have released power supplies with 12VHPWR interfaces, and it is believed that after Intel released the ATX 3.0 standard, more PC power supply manufacturers will launch corresponding products. However, considering the issue of compatibility, I believe that most power supply manufacturers will introduce support for 12VHPWR and now the mainstream 8pin excuse to meet the needs of use. In terms of graphics cards, the RTX 3090 Ti that has jumped tickets many times is expected to be launched, and the next generation of RTX 40 series and AMD RX 7000 series graphics cards should also have corresponding products, but at that time, graphics card manufacturers will provide conversion cables, or some product support, which is still unknown.
