Can I Replace my old PSU without taking the motherboard out?

[Kane_9]

I plan on replacing my old antec PSU with a seasonic one also is it bad if i unplug the PSU and hold the power button on my case and no discharge comes out before replacing it? What does that mean?

YES, the power supply is not attached to the motherboard. You dont have to press the power button for you to be able to replace the PSU and doing it won't damage anything since you have no current going through the system

You wont harm anything doing that. And yes, providing your PSU is not routed underneath your MOBO, you will be fine to replace the PSU without removing the MOBO. Good choice of replacement too! Always good practice to wear an anti-static wrist band when dealing with the PSU. They are cheap and readily available from loads of places.

It just means that either it's already discharged, or it discharged without you seeing it (which is what I'd expect).

You don't need to do that, just ground yourself to be sure you don't have any static charge so you won't damage your ICs. You can use a grounding strap, however many just touch the bare case away from the motherboard or add-on cards. You shouldn't need to remove the motherboard to change a power supply. Just take it slow and easy, you'll have the main power plug (24pin) to take off the from of the motherboard and the CPU power connect (4 or 8pin) to unplug from the motherboard. Then you just have the drives, fans and any PCI-E connections to your video cards to deal with.
