A black screen, crash, or shutdown while an RX 570 is under load can point to a power-supply problem, but it does not prove the PSU is at fault. Check the PC’s behavior, return hardware to stock settings, inspect the card’s power connection and airflow, and compare the PSU with your complete system’s requirements. If the cause remains unclear, testing with a known-working PSU is more useful than replacing one based on a single symptom.
What an RX 570 black screen under load can mean
Pay attention to what the PC actually does when the failure occurs. A full shutdown or restart is different from a black display while the computer remains active, and both differ from a game closing to the desktop. Note which workload triggers the problem and whether it began after a driver, BIOS, hardware, or tuning change. AMD’s system stability troubleshooting guidance recommends considering recent changes and workload conditions when investigating instability.
A PSU fault is one possible cause: AMD says a faulty or insufficient supply may cause boot failure, random crashes, hangs, reboots, or display corruption. Those symptoms overlap with problems that can come from the GPU, drivers, cooling, or other hardware, so the symptom alone cannot identify the failed component. See AMD’s PSU troubleshooting guidance.
RX 570 power requirements—and why the exact card matters
AMD lists 150 W typical desktop board power and a 450 W minimum PSU recommendation for the RX 570 on its RX 570 specification page. The 450 W figure is a recommendation for the GPU configuration, not a diagnosis of your current PSU or a guarantee that every 450 W unit is suitable for every PC. Consider the CPU and other installed components, and use the PSU’s rated output when assessing the complete system.

Board-partner models can differ. For example, MSI lists 120 W power consumption, one 8-pin power connector, and a 450 W recommended PSU for its Radeon RX 570 Gaming 4G. That specification applies to this model only. Check the label or manufacturer’s page for your own card rather than assuming every RX 570 has the same power draw or connector.
Work through these checks before replacing the PSU
- Record the failure. Note whether the whole PC powers off or restarts, the display goes black while the PC remains active, or only the game crashes. Record the workload and any recent system changes.
- Restore stock settings. Disable GPU and CPU overclocks or tuning utilities. If needed, restore default BIOS settings using your system’s instructions. AMD recommends testing stability at factory defaults in its stability guidance.
- Inspect the card, power connection, and airflow. Shut down and unplug the PC before inspecting hardware. Check that the card is seated in the primary PCIe slot and its PCIe power connector is firmly attached. If the card uses a riser, remove it for diagnosis. Check that vents are unobstructed and the PSU has normal airflow. If dust blocks the PSU vents, follow the PSU maker’s cleaning instructions; AMD mentions a compressed-air duster as a possible way to clear dust, not as a guaranteed fix.
- Compare PSU capacity and connections with the complete system. Read the PSU’s rated-output label, check the requirements of the other components, and verify the exact RX 570 model and connector. A PSU’s label wattage by itself does not establish that it is healthy or adequate for the system.
- Use a known-working PSU as a diagnostic test when practical. AMD recommends testing with a known-working PSU whose wattage meets or exceeds the system’s needs when power-related instability persists. Do not open a PSU enclosure. If you are not comfortable removing or replacing the PSU, seek expert assistance.
If the problem continues after power checks
If a known-working, appropriately sized PSU does not resolve the failure—or a PSU swap is not practical—continue checking other likely causes rather than treating the PSU as cleared or condemned by one symptom. Test memory and other hardware at stock settings as appropriate. Check GPU and system temperatures, and investigate whether the card or another component may be defective.

For software troubleshooting, update or clean-install the Radeon driver, review its release notes for known issues, and consider reverting a driver if the problem began after an update. AMD includes driver installation and rollback, as well as contacting the relevant system or component manufacturer when instability persists, in its stability troubleshooting steps.

Consider replacement when the current supply does not meet the complete system’s requirements or when testing and troubleshooting support a PSU fault. Choose by the PSU’s rated output, the correct PCIe connector and cable for both the exact card and PSU, physical fit in the case, and the manufacturer’s support and warranty terms. AMD’s specifications do not rank PSU brands or particular retail models.
