The Gigabyte Radeon RX 9060 XT Gaming OC 16G is built on AMD's RDNA 4 architecture. It sports a 128-bit memory bus, 16GB of GDDR6 memory, and a boost clock of 3320 MHz, which is genuinely quick for a mid-range card. AMD rates the TDP at around 150W, but real-world gaming loads can push that higher, and transient spikes during scene transitions can spike power draw briefly well above the rated figure. That is why headroom matters.

The card uses a standard 8-pin PCIe power connector. You do not need a 12VHPWR or 16-pin PCIe 5.0 connector, so any decent modern PSU will have the right cables. That said, choosing a PSU with ATX 3.0 or ATX 3.1 compliance is still a good idea. These standards require PSUs to handle transient spikes of up to 200% of rated power for brief periods, which keeps voltage rails stable when the GPU suddenly demands more power mid-frame.

For wattage, here is a simple way to think about it. Take your CPU TDP (say 65W to 125W for a typical Ryzen or Intel chip), add the GPU TDP (roughly 150W for the RX 9060 XT), add around 100W for storage, fans, RAM, and motherboard overhead, then multiply the total by 1.2 to leave a 20% efficiency buffer. That puts most builds in the 400W to 450W actual draw range, meaning a 650W unit is technically sufficient. However, 750W to 850W is the sensible target. It keeps the PSU operating in its most efficient range (typically 50% to 80% of rated load) and leaves room for future upgrades.

The GV-R9060XTGAMING OC-16GD connects via PCI-E 5.0 x16 on the motherboard side, but this is about data bandwidth, not power delivery. Your PSU does not need to be PCI-E 5.0 compatible in any special way beyond having the standard 8-pin GPU power connector. All eight units in this guide are fully compatible and verified to work with the card.

Understanding PSU Efficiency Ratings and Wattage for the RX 9060 XT

80 Plus efficiency ratings can feel like marketing fluff, but they actually mean something concrete. An 80 Plus Bronze unit is at least 82% efficient at 50% load, meaning for every 100W it draws from the wall, 82W reaches your components and 18W is wasted as heat. Gold improves that to around 87 to 90%, Platinum to 89 to 92%, and Titanium to 92 to 96%. The difference in your electricity bill over a year of daily gaming is real, especially if your PC runs for long sessions.

For the RX 9060 XT specifically, 80 Plus Gold is the practical sweet spot. Platinum and Titanium ratings cost more upfront and make financial sense only if your PC runs eight or more hours every day. If you game for two to four hours an evening, Gold is fine.

Wattage headroom is equally important. PSUs are most efficient when running at 40% to 80% of their rated capacity. A 750W unit powering a 400W system sits at 53% load, right in the sweet spot. Run a PSU at 95% of capacity under a heavy gaming load and efficiency drops, temperatures rise, and component longevity suffers.

Transient power spikes are a less-discussed but important factor. Modern GPUs, including AMD's RDNA 4 cards, can spike power draw briefly during scene transitions or shader compilation. ATX 3.0 and ATX 3.1 PSUs are specifically designed to handle these spikes without triggering overcurrent protection. Older PSUs can sometimes shut down or throttle when hit with a sudden spike, even if the average draw is well within their rated capacity. Choosing an ATX 3.0 or 3.1 unit removes that risk entirely.
