today i checked my psu voltages in bios ,
i saw that the +5v rail and +3v rail was fluctuating a little
the +5v is usally always at 5.080v but it sometimes goes to 5.120v for about 1 sec and comes back down to 5.080v in bios
is this a problem?
i thoght this would cause crashes thats why i asked
i am glad to help.
your motherboard and graphics card have little power supplies on the called VRMs (voltage regulation modules) they are just like your power supply except they use DC/DC instead of AC/DC.
the motherboard has them for the cpu, memory and igpu if its on the cpu. the graphics card has them for the gpu and memory. they (the VRMs) fine tune the voltage even more. so as long as the PSU is within the specs, they VRMS are made to be able to handle it and provide "smoother" power to the components.
