You can check the HP desktop's power supply by using a multimeter to measure voltage across the two 4-pin connectors. Look for consistent readings with the yellow/black and brown/black sets. If the power isn't reaching the correct values, it may indicate a faulty supply.
I'm checking the functionality to confirm it operates correctly.
The sudden black screen after a reboot often signals a GPU driver issue or a brief power interruption. With your temperatures normal and memory tests passed, let's investigate: Confirm you're using the most recent Intel Arc drivers, which have been improving stability. Reconnect the GPU power cables and verify the power supply connections. Perform a dedicated GPU stress test with FurMark or 3DMark to see if problems appear outside Train Sim World. If only TSW5 triggers issues, it might be an Arc driver quirk—Unreal Engine compatibility is common. Your PSU has ample capacity, so focus on software fixes rather than hardware replacements.
I placed an order for a replacement on Amazon, expected delivery tomorrow. However, I’m trying to figure out how to test it without connecting it to my power supply tester since I want to see if others have managed to do it independently.
You already have a PSU tester available, which is the simplest approach. If not, the best standalone method is to connect the 24-pin green to black and verify with a multimeter while under load—this reveals idle rails but not transient stability. The most accurate assessment comes from stress testing with the GPU or CPU drawing power, as this reflects real-world conditions. A dedicated tester or a reliable spare PSU remains the only dependable confirmation.
Thanks for confirming the misunderstanding. As a proprietary PSU without the typical 24-pin standard, a tester won’t be useful. Ordering a replacement was the best decision. When it arrives and you install it, you’ll be certain whether power delivery was the issue.
