In the recent press announcement by Gigabyte, they announced a brand-new power supply, dubbed the UD1000GM, which is designed specifically for PCIe 5.0 graphics cards to be released shortly. However, the most important feature to support the new GPUs is the addition of the new power connector of 16 pins on the UD1000M. This, according to Gigabyte, will be included in all of these new GPUs.

We announced its existence as a power connector with 16 pins at the end of last year. The new connector is designed to be an all-in-one replacement for the conventional 8-pin and 6-pin power connectors that will power the next generation of PCIe 5.0 GPUs and reduce clutter on cables in the process. While the new connector does have 16 pins, its overall dimensions are significantly diminished, making its shape aspect similar to an 8-pin connector.

The 16-pin’s power output is significantly improved, with 600W power through one connection. For reference, a standard graphic card that is a flagship today has three power connectors with 8 pins that can handle 500W each (150W in each of the connectors). This gives the 16-pin enough headroom to power any future GPUs if power consumption patterns remain similar to the RTX 30 and RX 6000 series flagship models.

The 16-pin connector has a strict connection compatible with PCIe 5.0 GPUs. It is unlikely to find this connector in a GPU with PCIe Gen 4. Gigabyte claims to be saying the same thing in its press release about the UD1000GM. The company also mentions that older and less traditional power supplies will require a triple 8-pin 16-pin adapter to work with PCIe 5.0 graphics cards in general.


This could mean that a 16-pin connector may be required for any GPU that wishes to utilize PCIe 5.0 specification. If this is the case, then those looking to upgrade to the latest GPUs must change their PSU or purchase one of these adapters that Gigabyte suggests.
However, this notion may be a lie. We aren’t sure 16-pins are necessary to support PCIe Gen 5. Nevertheless, this is likely likely to be the situation.


Thankfully, power supplies such as the UD1000GM have already come out with this brand new 16-pin power connector integrated. Asus announced an updated PSU lineup that includes the connector with 16 pins as ROG Loki one month ago. ROG Loki. With power supplies already adopting the new standard, there will be plenty of top models ready just in time to welcome the arrival of the next generation of GPUs, such as those in the RTX 40 series.
