Welcome to our HP Community forum!
The power supply of your HP Pavilion Gaming Desktop 690-0002no (3QY26EA) as fitted with the Lincs motherboard (SSID: 843B) can be upgraded with a 400-watt power supply with p/n: L04618-800 or a 500-watt power supply, with p/n: L05757-800.
Your motherboard is not compatible with 24-pin ATX power supplies -only HP proprietary power supplies, and there is no ATX power supply adapter available.
Kind Regards,
