So it looks as though AMD was a bit busy over the weekend! The new driver (16.7.1) will deliver a change to the power distribution at the PCIe slot which will most likely send more power through the 6 pin PCIe connector from the PSU. With the PCIe connector already out of spec, this is the best solution as most PSUs are built to withstand significant overages coming directly from 6 and 8 pin connectors to the PSU. There is also a new "compatibility" toggle that is "off" by default that you can enable to ensure that power delivery doesn't exceed specifications on either end (the slot or the connector). This in turn will reduce performance in games. Amd has stated however that the new driver has implemented changes that increases performance of popular titles by 3% which should equate to similar performance from original benchmarks with "compatibility" mode enable. So now that the updated driver will fix the distribution of the over current pulls from the motherboard, we can all rest a little easier. Although it is not indicated, it wouldn't hurt to ensure your PSU is up to par and is of the bronze/silver /gold rated variety!

AMD's full statement is as follows:

We promised an update today (July 5, 2016) following concerns around the Radeon™ RX 480 drawing excess current from the PCIe bus. Although we are confident that the levels of reported power draws by the Radeon RX 480 do not pose a risk of damage to motherboards or other PC components based on expected usage, we are serious about addressing this topic and allaying outstanding concerns. Towards that end, we assembled a worldwide team this past weekend to investigate and develop a driver update to improve the power draw. We’re pleased to report that this driver—Radeon Software 16.7.1—is now undergoing final testing and will be released to the public in the next 48 hours.

In this driver we’ve implemented a change to address power distribution on the Radeon RX 480 – this change will lower current drawn from the PCIe bus.

Separately, we’ve also included an option to reduce total power with minimal performance impact. Users will find this as the “compatibility” UI toggle in the Global Settings menu of Radeon Settings. This toggle is “off” by default.

Finally, we’ve implemented a collection of performance improvements for the Polaris architecture that yield performance uplifts in popular game titles of up to 3%1. These optimizations are designed to improve the performance of the Radeon RX 480, and should substantially offset the performance impact for users who choose to activate the “compatibility” toggle.

AMD is committed to delivering high quality and high performance products, and we’ll continue to provide users with more control over their product’s performance and efficiency. We appreciate all the feedback so far, and we’ll continue to bring further performance and performance/W optimizations to the Radeon RX 480.

1: Based on data running ’Total War: Warhammer’, ultra settings, 1080p resolution. Radeon Software 16.6.2 74.2FPS vs Radeon Software 16.7.1 78.3FPS; Metro Last Light, very high settings, 1080p resolution, 80.9FPS vs 82.7 FPS. Witcher 3, Ultra settings, 1440p, 31.5FPS vs 32.5, Far Cry 4, ultra settings, 1440p, 54.65FPS vs 56.38FPS, 3DMark11 Extreme, 22.8 vs 23.7 System config: Core i7-5960X, 16GB DDR4-2666MHz, Gigabyte X99-UD4, Windows 10 64-bit. Performance figures are not average, may vary from run-to-run.

With that said, if you are skeptical of that 450W Chinese PSU with rainbow colored wires that was included with your case when you purchased it, it might be high time to upgrade now that this fix is less than 48hrs away!

The thing I take away from this is the amount of control AMD has on their GPU's power circuitry with the RX400-series. And this is a reference card to boot !
