only_lonely Posted December 5, 2006 Report Share Posted December 5, 2006 I have a motherboard, it can power up by 5V.But i found it the only way i can power it and boot into windows is using parallel mode (master must in CV,slave in CC).If i want to see the current flow, then i need to sum the readings from master and slave.If i use indepent mode (Master:CV) to 5V, it will auto restart when RAM shadows finished.Cannot boot into windows.Can anyone here explain to me why???

audioguru Posted December 5, 2006 Report Share Posted December 5, 2006 You have two power supplies in a single case. One of them doesn't produce enough current so you must connect them in parallel but then must add the current readings. Of course the pc will auto start when a single supply is used because it doesn't provide enough current.Get a supply that can supply enough current.

only_lonely Posted December 5, 2006 Author Report Share Posted December 5, 2006 oh i see. thanks.but,may i know whats the theory inside the power supply series,parallel and independ mode? Quote Link to comment Share on other sites More sharing options...
mvs sarma Posted December 5, 2006 Report Share Posted December 5, 2006 Hithe CC mode is preset for a known constant current-- hence no need to measure.if you are able to measure the total crt, you can deduct CC paramter and balance is taken by CV unit.
