Fireboy Posted October 20, 2007 Share Posted October 20, 2007 My motherboard shows the PSU 5V as 4.9V. Is this a problem? Thanks! Link to comment Share on other sites More sharing options...
Wired Posted October 21, 2007 Share Posted October 21, 2007 searching the forum rocks :) As long as the +5v rail stays between 4.75v and 5.25v then it is within spec. There may be minor fluctuations between different PSU's however the BIOS and software voltage readings will never be 100% accurate. The only way to know the exact voltages would be to use an electronic VOM. Link to comment Share on other sites More sharing options...
