It looks like everything is now working smoothly, thank you everyone for your help.
The new 400W silicone bed heater is working great, heats up much faster and im finally not having problems with bed adhesion, couldnt even get PLA to stick on a leveled bed before.
The power supply was a 'future' upgrade ive been wanting to do, guess getting a kick in the butt to getting it done now to power the 400W upgraded bed heater was a blessing in disguise.
overall very happy
