This is the number i got when idling, when gaming it's go down. Should i get a better PSU ASAP?

Table below from this website: https://www.lifewire.com/power-supply-voltage-tolerances-2624583
PSU Tolerance Table
Voltage RailToleranceMinimum VoltageMaximum Voltage
+3.3VDC± 5%+3.135 VDC+3.465 VDC
+5VDC± 5%+4.750 VDC+5.250 VDC
+5VSB± 5%+4.750 VDC+5.250 VDC
-5VDC (if used)± 10%-4.500 VDC-5.500 VDC
+12VDC± 5%+11.400 VDC+12.600 VDC
-12VDC± 10%-10.800 VDC- 13.200 VDC

Some information: I'm grounding directly from the terminal not the case.

Noted that your voltage tolerances came via Lifewire.

@refillable 's post (Thanks) made me realize that you may not have used a multi-meter to get the numbers.

Here is the Lifewire "how-to" link for testing with a multi-meter.

If you do not have a multi-meter then try to find a knowledgeable family member or friend who does and also knows how to use the multi-meter.

Do be aware that the test is not a full test as the PSU is not under load.

However, any voltages out of spec make the PSU a prime suspect.
