Didn't I tell you? I have the A02 Rev and it still having incompility issue.

When I pop back my cheap Omni 500Watts it works flawlessly also when I was talkign to those seasonic tech they didn't tell me that A02 solve the problem. BEST of ALL ASK FOR A FULL REFUND!

Sh!t indeed, I still have my A02 laying around somewhere still don't know what to do with it. I am willing to sell it at 170AUD, buyer pay for Postage and handling (Australia only), payment = direct deposit. The PSU is very new, just got it for 2 week, powered it on once . email me @ [email protected]

OK, so are there any hard numbers available?

 

For the theory that the DFI pulls too much 5V, is there any number available how much it is supposed to poll and what the Seasonic PSUs deliver?

 

For the theory that the DFI does not pull enough current to make the PSU realize it is driving something, are there any numbers available what the minimum current for the PSU is and what (and where) the DFI pulls?

Now that more about the issue is known, does it look likely that the DFI Expert motherboard has the potential for the same problem with Seasonic PSU's? (does the Expert need as much from the 5V and will the EPS connector help)

The issue might be/have been +5VSB, not the main +5V rail &

we won't know about the Expert until we get them. :confused:

For what it's worth, my Seasonic s12-430 works flawlessly with an ASUS A8N SLI Premium. All I got were the 4 LEDs of death on my Ultra-D with the psu and hsf fans spinning normally with the Seasonic.

 

However my Enermax 535w works fine with the Ultra D. The Enermax specs say it has 2.5A on the +5v sb rail while the Seasonic says it meets the Intel specs of 2.0A on the +5v sb rail. Looks to my simple mind that the DFI Ultra D is pulling more than 2.0A on that silly +5v sb rail.

I believe that you are correct & I believe that putting a 1000uF cap across the +5VSB, may solve the problem.

just thought, you might want to mention if the cap is polarized or not.

I received my seasonic S12-600 (rev A02) yesterday, no problem, it's working well with my DFi nf4 ultra D.

 

The only bad thing is that with only one hard drive, my volts are:

 

3.18-4.86-11.95

 

please does someone know why I have low voltage with this PSU and only one hard drive?

First use a voltmeter to verify this is actually what you get.

Anyone care to elaborate?
