I really appreaciated your time going through my issue. Thank you Bill_Bright! And all others of course
I had the Antec PSU for 12 years, and it was hot here in Western Australia the day it blew up (42 °C ).
I was trying to simplify my situation, what really happened was I used one module cable (its longer) from Antec PSU on the Corsair, assumed it will be compatible but the board won't boot, so I unplugged all module cables on the PSU while the other ends are still connected to devices, so only 24pin and 8pin is connected to see if it will boot.
It booted, then the smoke happened so I shut the power immediately. I believe the card was drawing too much power from the PCIE slot on the board, with the PCIE 8 pin connected to the graphics card, not connected to PSU. I checked both card and board, can't see any visible damage. Rest you know.
I stopped using the Antec cable, everything boots fine, and now have the card in secondary PCIE slot, and a sound card in the first PCIE slot, so far no sign of abnormality.
I will test the outlets also, thank you again for the advice. it may have something to do with the old power board also died from the scene.
