Could this be a faulty PSU?

Hi everyone

Last week my USB expansion card, which sat in a PCI-E slot on my motherboard, was working fine. It then stopped working two days ago. The card was powered via connection to the PSU.

I have replaced the card today, however, there is still no joy. I switched my audio card with the slot the USB card was using. The audio card worked fine but the USB card still failed to function. Therefore I am assuming the PCI-E slot is not at fault.

Could this be down to an issue with the PSU? Everything else within the PC seems to be working fine. I have added no additional hardware to the machine since I built it a little over two years ago so it cannot be a conflict from new hardware.

Machine spec:

Intel(R) Core(TM) i5-4590 CPU @ 3.30GHz
Socket 1150 LGA (0x1)
2 x 8MB Corsair RAM
MSI Z97 PC Mate(MS-7850) Motherboard
NVIDIA GeForce GTX 750 Ti Gfx Card
256GB SSD
2 x 2TB HDD
Windows 7 64-Bit

Thank you in advance for your help.

It is on a chain with the fan on the back if the tower. The fan seems to be fine.

I'm unsure if it is a defective card as that doesn't explain why the other card ceased working. I can't rule it out of course, but it would be a big coincidence.
