What are Phase LED's

Hi,

I've been out of touch with the advances of computers, the last PC I built being a Pentium II! However I've just put together a desktop system based on an i7 and an MSI P67A-G45 board. Posted first time, seems to be running fine.

There are four blue LED's on the motherboard which according to the manual are phase led's, what do these LED's mean, all four are lit up but flicker quite fast (kinda like a HDD led), does this mean anything ?

I've struggled to find anything on google that really explain their purpose.

Thanks

the LED's are active if that particular power VRM or whatver its called is active, basically, from what i understand, all the led's should be on - that means the cpu power is being fed stably

Going on what panyan said if there flickering maybe you need a new psu ?

Thanks for your replies, PSU is a brand new arctic 700 psu, perhaps I should have got something a bit better.

General consensus is that the LED's shouldn't flicker at all then ?

hi, I have a P67a-gd65, mine flicker too, its normal, its just the voltage, etc...
in your bios, you there is an option to disable the LED's in the energy saving option
the led's are there just to look nice
- mine flicker more at certain voltages.
its not bad at all
