New PSU = Unstable.

post #1 of 34
Thread Starter 
Just got my Seasonic s12-600 in the mail. After plugging it in, and going back to my old settings...I'm not prime stable anymore....sup with that? I'm gonna play with some voltages, because this PSU is way better than the last one...maybe they're just off because of voltage. Anyone got any ideas?

probably it has to do with voltages. could be your rails are fluctuating too much. check them voltages with speedfan and see if they are within tolerance range which is stated on ur psu. also, whats the amps on ur 12v rail? i think u would need as a minimum 32amps. check it on ur psu label and see if its enough.

I've heard about Seasonic PSU's not being stable out of the box, it sounds faulty. Check it with a multimeter (ya can get them from Radioshack for $5-10), and see what it stands at. I suggest an RMA though.

18A and 18A.

How should I go about loading the separate rails? I have one string of connectors for the four plugs on the psu, and the other string for the drives, and fans. Is this good?

Multi-Rail PSUs will colour code the +12V - this is typically with a Blue or black stripe down it.

You will find that the Main 24-pin and +12v connectors are on one rails and everything else is on the other one.

Moving fans off the MB fan headers will help the MB and its stability.

Ensure all 4 connectors are securely made and as suggested use a good Multi-meter to read the values of the MB, esp the +12, +5, +3.3v

Do this when posting / OS booting, OS Idle, OS Load and see what the variance is.

Use MBM5 to then correctly offset the BIOS readings to display the 'true' readings.

Check Vcore against differnet Genie % settings as some of these are not as stable.

Look in the FAQ and also here to help you further.

I took all the fans off of the mobo. Still no good man. This is pissing me off. Why would an UPGRADE of a psu make it so ****ty at my old clock? The reason I got it was cause I was hoping to get a higher overall clock with it, or at least bring my memory up to 1:1. This is highly discouraging. This is the best PSU on the market, and it can't even compare to my Ultra 600W p.o.s.

Just tested with a Multimeter. The rails are almost dead on. Stable too.

What is wrong man? I thought this would be a good investment...doesn't look like it so far.

Are the fans spinning? Is there hot air blowing out the back of the PSU? Try resetting the CMOS? Maybe an BIOS flash to the latest BIOS? It sounds like a motherboard compatibility issue more than anything.

Sorry...you must misunderstand me. I can power on and get into windows. (i'm typing to you on this rig.)...It's just that my overclock of 2610 prime stable for 13 hours, is no longer prime stable...

The problem is NOT ur psu, trust me if it was the psu then that thing would've never turned on in the first place. when u say ur old settings u mean from ur old mobo settings right? the dfi mobo and psu is brand new right? u have to mess with the settings on the dfi mobo. after messing with all the bios option and timings i would suggest try using 2t instead of 1t.
