Guys I have a EZ Cool 600W PSU and when I fire up speedfan 4.28 it reads the following: -
Vcore1: 1.44v
+3.3v: 3.3v
+5v: 5.05v
+12v: 11.97v
-12v: -1.25v
-5v: -8.78v
+5v: 5.00v
Vbat: 3.04v
I am a little concerned about the -1.25v and -8.78v readings, should I be.
Also should I be looking for a new PSU as I need one to be compatible with my A8N32 SLi Deluxe board (24pin) with 2 x 6600GT GPU's (SLi).
Do I need 2 x 12v rails and whats this about 30A on each rail?
Anyone any recommendations.
Cheers Guys!!! :cool:
 
I *think* that the - rail isn't too important so wouldn't worry about that but I would ditch the cheap PSU anyway and go for something like the 700w FSP.

You don't need a PSU with more than 1 12v rail but more ampage is always good.There have been some cases where a single 12v rail PSU is better than multi rail psu.
 
Thanks for the advice weescott do you happen to know why I have a reading of -1.25v where it should read nearer to -12v.
Any PSU recommendations for a SLi config.
 
I'm not sure why your rail reads -1.25 but as I said I wouldn't worry about it as you need a new PSU anyway.

My rule of thumb is to get at least 550w for 1 high end card and 700w for SLI. You can afford less power for average cards such are yours. Something like a 600w Enermax would do for a system such as yours but if you upgrade to higher spec cards or CPU or overclock then the 700w FSP would be ideal.
