The 16-pin 12VHPWR connector is a standard for connecting graphics processing units (GPUs) to computer power supplies for up to 600 W power delivery. It was introduced in 2022 to supersede the previous 6- and 8-pin power connectors for GPUs. The primary aim was to cater to the increasing power requirements of high-performance GPUs.
The RTX 4070 was then released on April 13, 2023 at $599 US MSRP. The RTX 4060 Ti was released on May 24, 2023 at $399 US, and the RTX 4060 on June 29, 2023, at $299 US. An RTX 4060 Ti 16GB followed on July 18, 2023, at $499 US. On January 8, 2024, Nvidia released the RTX 4070 Super at $599, RTX 4070 Ti Super at $799 and RTX 4080 Super at $999.
For example, a 900-watt power supply with the 80 Plus Silver efficiency rating (which means that such a power supply is designed to be at least 85% efficient for loads above 180 W) may only be 73% efficient when the load is lower than 100 W, which is a typical idle power for a desktop computer. Thus, for a 100 W load, losses for this supply ...
#PS_ON pin is marked by number 16. PS-ON Signal is a pin on a 20-pin or 24-pin ATX-specified power connector used to turn a personal computer power supply unit on/off. The PS_ON pin is normally pulled high in an open-circuit, but will turn on the power supply when it is pulled low, by shorting it to the common signal (COM).
80 Plus (trademarked 80 PLUS) is a voluntary certification program launched in 2004, intended to promote efficient energy use in computer power supply units (PSUs). Certification is acquirable for products that have more than 80% energy efficiency at 20%, 50% and 100% of rated load, and a power factor of 0.9 or greater at 100% load.
The main 12 V power supply for the PCIe slot is pins B2, B3 (side B) and pins A2, A3 (side A). Power standby 3.3 V is pin B10 and A10. PCIe x1 cards can receive up to 25 W and x16 graphics cards can receive up to 75 W , combined.

The ATX specification defines the Power-Good signal as a +5-volt (V) signal generated in the power supply when it has passed its internal self-tests and the outputs have stabilized. This normally takes between 0.1 and 0.5 seconds after the power supply is switched on.
