Delay when you press the power button, then the machine starts up
I made the processor and motherboard upgrade on my desktop last weekend by installing a Ryzen 7 3700X and an ASUS ROG Strix X570-E board with 2x16 GB Corsair Vengeance RGB Pro 3200 MHz CL16 RAM. Since then, I've encountered problems when trying to start the computer. After turning it off and pressing the power button on the front panel, nothing activates for a few seconds before everything turns on normally. This delay seems consistent each time, but I haven't measured it precisely. I suspect a few things: I turned DOCP overclocking on the RAM to match its rated 3200 MHz, my old PSU is struggling but worked fine with an older i5 6600 K on an ASUS Z170-K board with 48 GB Corsair RAM, and the new motherboard has two 12V EATX ports—one 8-pin and one 4-pin. I connected only the 8-pin version. The total power draw for my build is about 380–400 W, which should fit a 620 W PSU even though it’s starting to lose efficiency. After a brief delay, everything functions properly. Should I still be concerned? I’m thinking about upgrading to a modular PSU later so I can upgrade the GPU. Is it safe to wait and troubleshoot further, or should I investigate further now? Could this be because the system needs more power at startup before stabilizing? I’ve ordered a PSU tester, but I’m unsure if it will help pinpoint the problem. Any advice or suggestions would be appreciated.
Several people have pointed out that one of the capacitors on the motherboard might be having trouble discharging properly. The 5-10 second pause likely reflects how long it takes for the capacitor to release its charge. After turning off the computer and unplugging it for over a day, it usually boots up correctly the first time, which aligns with this idea.
