Upgraded my power supply to a corsair 750. Went to turn it on and yhe cpu fan and graphics card fan spins maybe once.
Mother board is a msi 760gm-p34. The board has a 4pin cpu power clip. The power supply came with an 8 pin that breaks in half.
Put the old power supply in and does nothing.
Put the 750 back in and it responds again with fans spinning halfway then nothing.
