We still don’t have PCI Express 5.0 power supplies, and although a few have already been announced on the market, not all manufacturers had joined the party. This time it’s GIGABYTE’s turn with their UDM1000GM PG5 power supply, the first to feature a 16-pin 12VHPWR connector.
The PCIe Gen 5 power connector is still a huge unknown in terms of its operation. While we know it’s going to be able to deliver up to 600W of power over a single cable, its full specs and operation have been a bit of a mystery to say the least. Although little by little new details of the 12VHPWR connector are becoming known. The latest have come with the GIGABYTE UDM1000GM PG5 power supply.
The UDM1000GM PG5 power supply joins those already seen by MSI and ASUS, and shows us how we are actually going to have two PCIe Express 5.0 connectors. One of 12 pins at 450 W and another of 16 or 12+4 of 600 W of power
UDM1000GM PG5, GIGABYTE’s First PCIe Gen 5 PSU
GIGABYTE has just introduced its first power supply with the new 16-pin PCI Express 5.0 card connector, which will power the next generation of graphics cards. An F1000 W power supply with 80 PLUS Gold certification.
New 12VHPWR connector details
Through a press release, related to its new UD1000GM power supply, the people of GIGABYTE have dropped new information about the PCIe Gen 5 power connector that has created more questions than answers.
The UDM1000GM PG5 power supply supports PCIe Gen 5 graphics cards and is capable of delivering the ever-increasing power that high-end graphics cards require. traditional power supplies need three 8-pin to 16-pin connectors to support the latest graphics cards The new UDM1000GM PG5 power supply requires a single 16-pin cable to power the PCI Express 5.0 GPU. Furthermore, the 16-pin cable provides up to 600 watts of power while solving the problem of the number of cables.
The statement that we have highlighted in bold draws powerful attention for a reason, we know that each 8-pin cable within the PCI Express standard can provide 150 W, so three of them combined will provide 450 W. This is obviously less than 600 W, but I would have an explanation. Since GIGABYTE could really be referring to NVIDIA’s 12+0 cable, since let’s remember that new cable and 12+4 or 12VHPWR connector It is compatible with the one used in the Founders Edition of the RTX 30. With which the RTX 3090 Ti will be able to get the 450 W of power it needs, but which has so far been limited to 300 W due to the limitations of the current PSUs.
The new PCIe Gen 5 connector is an extension of NVIDIA’s
The relationship between the NVIDIA 12-pin connector and PCIe Gen 5 is easy to understand by looking at both cables, the cable has the same 12 connection pins, but the 600W version has an additional four pins giving it the 150W remaining power. So the most logical explanation is none other than the four final pins are different so that the fit of the two connectors is exactly the same. This will mean that there will be two types of connectors on graphics cards and, therefore, we will see models with consumption of 450 W and others of 600 W. The high-end RTX 40 and RX 7000 are expected to reach use all the maximum power of the new PSUs.
