HDPlex 400watt DC ATX help!


Recommended Posts

I think I killed it.

 

Got everything plugged in to my new server using HDPlex 300W LPS. Good to go (or so I thought) I turned on the server. Got a blue front panel light but nothing through to the monitor. It's silent so hard to tell what's going on. I did note that there was an amber LED at D12 I turned everything off and rechecked.

 

Damnit. I found the voltage setting for AC power was set for 220volts. Flipped it to 120 and tried again. Now I have a blue LED at D12. I don't know what the blue LED denotes. Looking at the online documentation it shows 4 LEDs on the HDPlex ATX. None of those are lit. And I get no bootup screen. 

 

Also noted that when the server is powered down, blue light turns amber.

 

Waited for a long time to F this up.

So ask HDPlex - they are nice people and I have found them helpful in the past.

Check where you have the 8-pin ATX connector plugged in on your mobo.  I mistakingly had it plugged into the wrong place when I installed the same HDPlex 400.

Yes they are nice people. Unfortunately, they have not been able to find a problem. They have asked me to try a standard ATX power supply to see if its a problem with my brand new motherboard. Normally, I would have a few in my spare parts bin, but the bin is in another state.

All connections have been checked multiple times. It was a logical thought, thanks Steve.

I had something similar when I tried to boot my server for the first time. The were some signs of life that the board was powered but it didn’t even do the initial BIOS part of the boot. After a lot of searching, I discovered that the DIMM modules weren’t quite fully home. I reinstalled them making sure that I heard a proper click and all was well at my next boot attempt. Might be worth a check?

Try clearing the CMOS, I had issues with my HDPLEX 800 watt DCATX and HDPlex 300 watt LPS, had smoke come out of both. I thought I trashed everything, I picked up a Corsair PS and cleared the CMOS, was able to get things up and running.

Hope you figure things out!

Thanks guys, I figured it out. The HDPlex appears to be DOA. I plugged my son's laptop power brick and viola, a working server. I then plugged the HDPlex into my son's laptop and it wouldn't even charge. 

 

I measure 18.94 volts output from the HDPlex but don't know how much current is available when plugged into a load.

 

Larry at HDPlex is shipping me another unit. Really great guy to work with and as mentioned here in this forum, responds very quickly to emails. 

 

I'll be buying more product from this company. They appear to be Pass Labs like (the gold standard in taking care of their customers) and that's who I like doing business with.
