Switch Posted December 22, 2006 Share Posted December 22, 2006 Perhaps I'm being slightly paranoid, but I've checked my voltage on SpeedFan recently (I realise these programs are hardly 100% accurate, but still), and noticed there's a fair amount of fluctuation on the +12v rail. I've read that this is fairly common, and that it has a tolerance for this... just wondered if anyone knows if I'm within that tolerance from looking at this? (+12v is the red line). I don't know much about PSUs really. http://img.photobucket.com/albums/v412/SwitchXP/voltage.gif Just a little wary of these things after my last motherboard blew (most likely due to unstable voltage).

Marxist ßastard Posted December 22, 2006 Share Posted December 22, 2006 The rule-of-thumb is ±5% --- which means that the fluctuations you're seeing are well within the acceptable range. Your paranoia likely springs more from the fact that the graph is biased toward displaying the lower voltages as being more coherent than they actually are. If you look at it in terms of the percentage of the target voltage that the actual voltage deviates from, instead of just the number of volts difference between the two, your 5V rail is probably fluctuating just about as much as the 12V is.

Switch Posted December 22, 2006 Author Share Posted December 22, 2006 That's true I suppose. Well that's a relief, thanks. :P Just wanted to be sure. Link to comment Share on other sites More sharing options...
