Choosing a PSU For the RTX 3090 Ti

When it comes to PC upgrades, many gamers are focused on the latest GPUs, but a power supply unit is an overlooked component. Without a strong PSU, even the best GPUs won’t perform at their best. Nvidia recommends a 750W power supply for the 3090 ti, and that’s the minimum you’ll want for this graphics card.

The RTX 3090 Ti is the first Nvidia GPU to use a new 1x16-pin PCIe power connector, which is different from the traditional 12 pins found on most graphics cards. This means that you’ll need a new power cable to connect your GPU to your motherboard. Some manufacturers, like Zotac’s Suprim X, include this new connector in the box, so you don’t have to buy it separately.

Despite the increased power demands, the RTX 3090 Ti is still overkill for gaming short of 4k high framerates. The card was designed to replace the Titan RTX, which is a professional GPU meant for rendering and other tasks that require high framerates.

Fortunately, there are several budget-friendly power supplies that will provide enough power for the RTX 3090 Ti and other gaming components. The Corsair RM 750x, for example, has the recommended wattage of 750W and can easily power the RTX 3090 Ti while leaving plenty of headroom for other components. It also features overvoltage and short circuit protection to prevent damage from power surges. Other factors, like the number of modular cables and efficiency rating, can also influence your choice, depending on your build goals.
