Along with the big news from Nvidia detailing their upcoming next-generation 30 series GPUs, we’re starting to see other manufacturers update their product lineups to target anyone looking to build a new system around a brand new RTX 3080, RTX 3090, or one of the other new Nvidia cards.

One such manufacturer is Gigabyte, who are updating their line of power supplies, with two new models specifically designed for use with RTX 30-Series GPUs. The all-new P850GM and P750GM modular PSUs offer 750-watt and 850-watt power output respectively and come with 80 plus Gold certification. Here’s Gigabyte’s description:

“The P850GM and P750GM both provide four 6+2pin PCIe connectors to support the large-wattage graphics cards and two 4+4pin CPU connectors to fully support mid- to high-end motherboards. The main capacitor is made in Japan and the PSUs have passed the 80 PLUS Gold certification, providing more than 90% conversion efficiency, allowing gamers to enjoy a high quality and stable power supply while saving a lot of money. The reduced-size power supply is more suitable for installation in the increasingly popular small chassis, so that even small chassis can enjoy the high performance brought by the large wattage.”

Sadly these PSUs do not come with the new format 12 pin connector out of the box, meaning that you’ll still need to use an adaptor that will ship with most of the RTX 30-series GPUs, but it does make it easier to use with existing components.

The exact wattage requirements of any particular build will depend on a wide variety of factors. We have a handy Power Supply Calculator tool available here, that we’ll be updating to include the latest RTX 30-Series GPUs from Nvidia once we’ve been able to test them. As a general rule of thumb, if you’re opting for a mid-range CPU paired with an Nvidia 30-Series GPU, you’ll probably be fine with a 750w power supply, but if you’re pairing a high-end GPU with a top-end CPU, you’ll be better off with the 850w option.
