PCIe Disaster Help!

Hello,

Recently I've needed to have Thunderbolt on my rig, and I did not want to replace the motherboard and move everything to a new one with Thunderbolt and pay for all that and have to put thermal paste on the CPU and all the software stuff you have to do. Too much work, too expensive.

Instead I found online this Thunderbolt PCIe expansion card by HP. They market it for their workstations but I figured it is like any old PCIe card and would work in my computer so I bought it. Here it is here: http://www.bhphotovideo.com/c/product/1039491-REG/hp_f3f43at_hp_thunderbolt_2_pcie_1_port_i_o.html

Today I got it, installed it in an open PCIe slot, and then hit a brick wall. The thing comes with 3 different cables you can use to connect to the power supply. They are all kind of weird and the instructions only provide for where you can connect it in an HP workstation. I installed the driver that came on the CD on my PC and it installed flawlessly, but did not detect the card.

One of the cables has one end that goes in the card and the other looks like the plug on a case fan, with only 2 holes instead of 3 or 4. I tried plugging that into a fan plug on the motherboard and nothing happened.

The other cable has 2 plugs coming out of it and they look like what you would plug into the USB slot on the motherboard if your case has USBs in the front.

Attached is a picture of the third cable. They are all weird and I do not know what kind of adapter I need to plug it into my power supply. There are only 2 wires available on my power supply--the one that looks most promising is a 2 pin cable.

Any ideas?

Thanks.

"They market it for their workstations but I figured it is like any old PCIe card..."

Wrong. In fact the card has to plug into a specific PCIe slot depending on which HP workstation you have. That means it is hardware specific. Read the "Note" section on the sheet behind the cable in your dropbox photo.

Try to get your money back. Even if you figure out the power connectors, it probably won't work and could potentially damage your PCIe bus and/or chipset/processor on the mobo.

RTFM.

It was actually someone on here that told me it will work. The driver installed without finding fault in that it is not an HP machine and the software is installed, but can't detect the card since I can't get power to it.

If I could find a header that would work with my PSU and the card than why would it not work?
