Define completely broken. Can you measure resistance with an ohmmeter? If so check the resistance between ground (3 pins on top of the PCIe plug) and pins 4,6,8 on the 10 pin header. Let me know the values.
Repairs are 5ltc plus shipping (probably a LTC) and my address is:

Let me know the tracking number and do not use UPS, use China Post to US Postal service. Works fine.
