Gigabyte Unveils Company’s First PCIe Gen5 Compliant Power Supply Amid Growing Confusion


Gigabyte introduces its all-new UDM1000GM PG5, a 1000W power supply unit (PSU) with an 80+ Gold efficiency certification. Gigabyte’s latest power supply is more consolidated than most competitors’ power supplies offering full modular connectivity. Gigabyte has also included next-gen PCIe Gen5 connectors, becoming the new standard for power supplies and working with the latest graphics cards.

Gigabyte UD1000GM PG5 is the company’s first PCIe Gen5 compatible power supply.

PCIe 5.0 is the next generation power standard and is compliant with the previous generation PCIe 4.0 standard. Bandwidth and transfer rates are twice as fast as PCIe 4.0, allowing data to be transmitted at remarkably faster speeds. PCIe 5.0 offers 32 GT/s and transfer rates of up to 3.94 GB/s. The specification is officially named the “12VHPWR” specification. The new PCIe standard has caused confusion in the manufacturer market as they do not understand how it should be documented.

Gigabyte is one of the manufacturers that confuses not only themselves but also their users. For example, the new UD1000GM PG5 uses up to four different terminologies for the next generation cable and connector:

  • PCIe Gen5 Cable
  • 12+4 pin cable
  • 16 pin cable
  • 12VHPWR

Gigabyte further confuses customers by using all four names and this description on their product page.

As for the power supply itself, it is a new variant of the existing model. The new version replaces two 8-pin power connectors with a single 12+4-pin cable.

While all of these titles are correct for the technology, the addition of many names will complicate matters when users try to purchase Gigabyte’s latest power architecture.

VideoCardz notes that there are already 6-pin, 6+2-pin, 8-pin and 12-pin types of power cables. The next generation of the 12 pin would be the adopted 16 pin cable connection. The 16-pin cable may have 16 connection pins, but it is a mix of 12 main power connectors and 4 data cables. The cable and connection are PCI Express compliant and include increased security at the link, allowing power consumption levels as high as 600W.

Gigabyte has yet to reveal a launch date or estimated price for the new UDM1000GM PG5 power supply. However, with the NVIDIA GeForce RTX 3090 Ti graphics cards on the horizon, which use the PCIe Gen5 connection, manufacturers such as ASUS, MSI and CoolerMaster are already showing their versions of power supplies for the next generation.
