View Full Version : The killer Phanteks power splitter

05-10-2016, 01:16 PM
So, I rewired my build today, pressed the power button to see my board turn on then off again. Then I tired the ITX side, same story. I try a known good power supply, my atx side is dead, CPU, motherboard, All my drives (that means all of my pictures too if both my drivers died, yes I only backed up on that other drive). It also took my power supply. The ITX side however lives on that second power supply, but none of my drives are found by the BIOS anymore. I'm about to dissemble the whole thing and start testing very isolated to determine the full damage it caused I'm hoping it's less than what it seems.

I then opened up my power splitter to see how it looks and I can't believe a company would sell this product.

Pictures to come.

Confirmed dead so far:

OCZ Vector
2TB WD green (Secondary back up drive, the newer one)
MSI Z170A Gaming M5

Confirmed alive and fully tested:

Samsung 840 EVO
2TB WD green (storage drive, the older one)
FM2+ motherboard, processor and RAM
MSI gtx 970
Antec edg750

Untested so far:

Adata sp900 256gb M.2
2*4gb gskill ddr4

Possible causes:

Power Splitter sub par quality
PWM hub not preventing 12v from going through the sata power the wrong way

Wow! :eek: What caused the short? :confused:
You definitely have my empathy on this one. I've lost HDDs, MBs, PSUs, etc, but luckily never all at same time .. even when I lost a system to lightning strike.

No idea. By the looks of the internal of the power splitter I think it's easy to see that it's my #1 suspect right now.

It's odd, the ITX system drives died,but the system survived. The ATX system drives seem fine but the system died.

I just need to find a friend to see the extent of the damage.

I had connected to the power supply both pwm hubs one was with both SSDs on a single modular cable and the other was in similar fashion with the two HDDs.

I'm no electronics expert, but from what little I know it is quite hard to say what the source cause was, or if the PSU, Phanteks Power Splitter .. or possibly an end use item was the origin of the problem.. Once the orign of problem overloads, it overloads the entire circuit and if fail-safes fail things fry. Normally PSU fail-safe trips off when this sort of thing happens, isolating and stopping potential damage. I'm not sure how the Power Power Splitter works so hesitate to hypothesize any farther. At a guess it is just that, a splitter with switching abiltiy to start PSU with either system. Have you contacted Phanteks?

Edit: was looking at what is dead and it seems they are all 5.5v power may be the power involved. No idea of cause.

The motherboard is 12v mostly, it has all voltages though

I say 5 volt because that is what HDD, SSD, motherboard, etc all have as common voltage, but it's only a guess. ;)

The pwm hubs don't have anything preventing 12v from going the wrong way also.

The red light by the 24-pin cable isn't suposed to be on while power is plugged to the board, only when it powers on... This is my test setup also where I tested all the things. Everything was tested with an Antec HCP-1300 and an Antec VP450 to make sure. The Antec EDG750 seems to have survived the ordeal also as it powered the ITX setup earlier for testing.

I'm in contact with MSI for them to help me trouble shoot this motherboard in case it can still live, however it seems grim.

I sent my Power Splitter and PWM hubs Monday. I still have no way of testing my 6600K and 2*4GB DDR4 memory.

I could test them, but posting to UK might be a little expensive. Maybe someone closer to you could put them int their system and test them.

Generally CPU will not damage motherboard, but I know one guy who had a bad CPU & motherboard combo that damaged a second motherboard testing the CPU.

I'm not fond to send it anywhere since my chip is delidded. Just shipping within the province would cost me like $40 for both ways.

Sad to see Phanteks not stand up on this more and get to the bottom of this catastrophe.
