Repaced PSU and graphics card, computer not powering up

[Aaron Hammerton]

Just replaced PSU and graphics card in a computer but its not powering on. What should I be checking as the cause of the issue

If your computer is not booting up at all, you must check your PSU. One of the most common errors is people forget to connect the 4 pin cpu voltage from the PSU. Check all your connections and see if it boots up properly~ Good luck!
