Random unexpected restarts using an old power supply, system fails to boot with a new one
Hi, I see you're dealing with a power supply issue in your system. The problem might be related to compatibility between the new PSU and your motherboard. Even though you used the correct cables, the connector types on the new Corsair PSU differ from the old EVGA model. This could cause the system to recognize power but not properly engage it. Checking for updated PSU specifications or consulting forums might help you find a suitable replacement that matches your board's requirements.
Ensure all cables match the Corsair PSU specifications. The Corsair PSU cables are marked "Type4" on the connector. If I were a gambler, I'd guess you're using the EVGA CPU power cable.
Thanks for your message. I mostly replaced all the Corsair cables, except the "type 4" CPU cable. The only cables I kept from the old PSU were for the SATA drives. It seems these newer PSUs might still work with older motherboards, though I'm not certain. Hi 191x7, the motherboard has a power button light that activates when you connect the PSU and flip the switch.
Oh... Then there's a real possibility that you have fried your storage drives and anything else that was plugged in to the SATA drives. You cannot mix any of the cables. With any luck maybe the PSU tripped protections and shut down before any damage was done to your SATA devices. The Corsair PSU cables are compatible with the motherboard. The cables that plug in to the motherboard/components all use the same standard. The problem is you're using EVGA cables that are not compatible with your power supply. The cables are wired differently for each power supply, the end that plugs in to the PSU on the modular connectors is not standard and all the different PSU brands wire it differently, sometimes even PSUs from the same brand are wired differently. You cannot mix modular cables between different power supply brands/models. You have to use the cables that the power supply comes with. For all of the cables. Look at the difference in how the SATA cables are wired on the PSU side. https://pc-mods.com/blogs/psu-pinout-rep...les-pinout https://pc-mods.com/blogs/psu-pinout-rep...les-pinout Unplug everything. Rebuild the system using ONLY the cables that come with the power supply you are using. Try booting the system without any of the storage or other SATA devices installed.
