Good Afternoon,
This is a silly and trivial problem that is monumentally solution-resistant.
I have on order an ASUS Essence STX PCie sound card that requires 20W auxuliary power to run the headphone amplifier.
The connector on the card looks like this:
Which connoisseurs of connectors will recognize as 4-pin Molex male.
The thing is, the only auxiliary power connectors I can find in the z620 are two 6-pin PCI female for power to GPU's. I'd like to have those available for GPU's- the system will have a Tesla M2090 that can run off a single 8-pin but is specified to run on one 6 pin + one 8-pin.
I've looked through hundreds of cables from several sources and can not find a 4-pin molex fem to 6-pin PCI male cable OR 4-pin Molex fem to 4-molex fem > Molex male to 6-pin PCI.
Are there any other power sources to which I can connect? SATA power ? Anything? I suppose I could eventually contrive a two cable solution, e.g, PCI power to SATA power to> gender change SATA power to 4-pin Molex Female, but my head is spinning already,...
It surprises me that a sophisticated, high performance, and expensive workstation such as the z620 with up to 80 PCIe lanes for peripherals is so sparse of power connections. The Dell Precision T5500 has two 6-pin PCI, two empty Molex 4-pins, connectors for a second optical drive, and etc.
This is a small detail that is disproportionately difficult.
Thanks!
Cheers,
