PCI-SIG Warns of Potential Overcurrent/Overpower Risk With 12VHPWR Connectors Using Non-ATX 3.0 PSU & Gen 5 Adapter Plugs
With next-gen approaching launch soon, one of the main components that users would want to update for their PCs is their PSU. This is due to new requirements and standards that have been set in place to deliver sustained and clean power, avoiding any issues in regard to transient spikes and power excursions. While there are many manufacturers who are bundling Gen 5 (12VHPWR) connectors with their existing PSUs, here's why it is a much better choice to invest in a real ATX 3.0 compliant PSU.
PSU manufacturers are getting ready for a grand launch of their new ATX 3.0 designs but there are also certain manufacturers who are bundling their existing ATX 2.0 PSUs with Gen 5 connectors. As expected, upcoming graphics cards are going to be really power-hungry and would require up to 600 Watts of power.
The 12VHPWR Auxiliary Power connector is designed to deliver up to 600 watts directly to a PCIe* Add-in Cards. This power connector is not compatible with the existing 2x3 or 2x4 auxiliary power connectors. The 12VHPWR connector power pins have a 3.0 mm spacing while the contacts in a 2x3 and 2x1 connector are on a larger 4.2 mm pitch. The 12VHPWR auxiliary power connector includes twelve large contacts to carry the power and four smaller contacts beneath carrying the sideband signals.
