The issue might be related to the power supply unit.
My child received his gaming PC from a friend for his birthday. It was an older model running a 2070 processor. It’s an ibuypower unit. Last year he upgraded it and gifted my son this one. The device seems to have been in use for some time, but it’s not turning on. I suspect the power supply is faulty. I’ve attempted several fixes—replacing the battery, reseating RAM and GPU, and even connecting the HDMI directly to the motherboard—but it still won’t power up. The lights come on briefly, and the fans spin slowly, suggesting insufficient power. After removing the PSU and taking photos, I’m unsure what to do next. I’m struggling to identify a suitable replacement since I can’t test the unit myself. Please let me know if you have any advice or resources. Thank you in advance for your help!
These are typical ATX PSU connectors, so any ATX PSU should fit. What is your currency and budget? The MSI A750GL offers a solid and dependable option without being overly expensive. Be sure to avoid using the original cables from older power supplies—especially if they’re modular or semi-modular, even if they seem intact.
It's not a modular setup, thank you for pointing that out—it would have been better to use the old cables. Thanks for the reminder! My currency is USD and I don’t mind the budget much. I’m okay spending a bit more if it means the item will last longer. I’m comfortable with anything between $150 and $200.
motherboard, CPU, RAM, power supply, and possibly a GPU if the CPU doesn't have built-in graphics. Use a screwdriver or small metal tool to touch the power-on pins on the motherboard's front panel header to potentially initiate startup.
The PC started functioning after we installed it, and it's been running for about eight months now. Suddenly it stopped working. I'll check if my friend recalls the ibuypower details. The lights and fans keep running until I turn it off. I didn't search for error codes, so I'll send the power supply back along with that information. We have all the original drives he used; he cleaned them up and we haven't encountered any issues. It boots from an SSD as expected.
It seems @Hinjima's idea points toward a good power supply unit. I'm in agreement—it might be around 8 years old, which aligns with typical lifespan expectations, and fixing it could be fairly straightforward. Checking the manual should clarify the plug locations; a motherboard manual would be helpful too. Best of luck! Debug lights on the motherboard might indicate issues, but if it doesn't power up, replacing the PSU is likely the solution.
