AMD have a reputation for creating fantastic graphics processors across the entire spectrum of price and design points, and their RX 6600 XT model is no exception – even if it is of the older generation of GPUs. It can still hold its own in a PC build, especially when paired with the perfect motherboard and power supply – but what is the best PSU for the RX 6600 XT?

If you are building or re-building your PC, and want to answer that question yourself, we’ve got you covered! We’ve put together a buyer’s guide for the best options that match the RX 6600 XT’s PSU requirements, accounting for budgets or specialist needs. Any of these PSUs are sure to super-charge your computer when factored into your build!

RX 6600 XT Power Supply Requirements

The minimum RX 6600 XT PSU requirements specify a wattage of 500W, with 160W of this going towards the GPU itself. This is relatively low, especially by today’s GPU standards, which is not the benefit it initially seems to be. A lower-rated PSU will not be feasible in the long term, which is why we always recommend PC builders – especially first-time PC builders – buy a higher-wattage PSU, as it can last them through several generations of other components. In the modern, upscaled PSU market, it’s also difficult to even find a unit with a wattage as low as the RX 6600 XT minimum PSU – even some of the cheapest PSUs on the market have a higher specification.

Our choices today range from 650W through to 850W, covering the general average for mid-range PCs. There are higher-tier PSUs for the RX 6600 XT, but a 1000W or higher PSU will have no effect on performance and not be worth the extra cost.

FAQs

What is the RX 6600 XT minimum PSU?

The RX 6600 XT has a power supply requirement of at least 500W. GPU manufacturers tend to slightly increase their products’ required wattage for safety, but for performance and longevity we wouldn’t recommend a PSU with wattage lower than 550W.

Is a Gold-rated PSU good?

Yes: Power supply units rate their energy efficiency like medals, meaning that Gold-rated PSUs are some of the most efficient on the market (second only to Platinum). This means your PC has a lower operating cost, and draws only the power it needs with little waste.
