so I'm having issues with a pc. the pc was already built to work but i've wanted to change the graphics card but the current psu wont be able to handle it alone because its underpowered, the psu is 240watts and its already powering everything else with only 2 cables, originally the 2 cables would transfer the power to everything like the gpu but the new rtx2060 needs a 8 pin connector and wont have enough energy from the current psu since it also has no 8 pin connector, the connectors included are a 6 pin connector which i guess works for the motherboard without 24 pins like others do and there's another 4 pin connector that i guess powers the cpu and thats it. I think its a dell 3668 or 3650 motherboard.
Could one psu thats 240 watts power the mother board and rest while another psu thats 200watts directly goes into the 8 pin connector graphics card, will ther be any problems with this? If only the 8 pin connector is connected?
