i7 2600k (OC ~4,3 GHz)
ASUS P8P67 (REV 3.1) (ASMedia USB 3.0 drivers aren't compatible with Mixed Reality)
16GB DDR3 (1600MHz)
A SSD and 3 other HDDs
The Headset: HP VR1000-100nn
The USB 3.0 PCIe Card with VIA Chipset and external Molex Power (only german amazon link available)
I installed the card in my motherboard PCIe 1x slot above my graphics card, powering it per molex, and I used to run Mixed Reality just fine.
After ~5 months of usage my headset turned itself off while playing BeatSaber; the cable got burned and it smoked. The headset itself got damaged, too.
We sent the headset back and bought the same PCIe card again, so we would have no issues with the old card.
I plugged in the new headset in the new USB 3.0 PCIe card powered with Molex, and the same thing happened.
The headset and my cable got burned, not even getting detected by Windows and the card apparently "crashed", according to device manager.
I did test the USB 3.0 PCIe card by putting my USB Stick into it, worked just fine. I could transfer files without it exploding or something.
Now, the headset itself still works, I got a new cable and got to test it on a friends Ryzen 5 2600 PC, no issues, except it didn't work in the USB 3.1 Gen2 port, for some reason.
I still want to play VR in my home though, that's why I thought of buying ANOTHER PCIe card, the Inateck KTU3FR-4P, hoping that the Fresco Logic "FL1100" chipset and SATA Power could help my situation (being recommended on reddit and officially from oculus, as I have heard) or else I would have to buy a new Motherboard, Processor and RAM or get a Laptop with enough performance to handle VR.
I want to mostly know how this issue came to be, is it that my headset drew to much power and destroyed itself or is my PSU acting up? Was the PCIe card simply built too cheaply and that's why it couldn't handle the VR Headset?
