2 PSU's blow in 18 months

Specs: Windows Vista 64 Home premium
I built a computer about 18 months ago using the following components.

Corsair TX750w PSU
AMD Phenom Quad Core 2.2ghz
Gigabyte Motherboard GA-MA770-DS3
Nvidia 8800 GTS DDR3 640MB
4x 1GB Geil 800mhz DDR2 RAM
2x 250GB Western Digital Caviar (RAID 0)

The PC worked perfectly for about 10 months and then the 1st PSU blew up. I contacted Corsair in Holland and they sent me a replacement upon inspection of the PSU. I chose Corsair thinking that it is a quality company offering a 5 year warranty.
I installed the new PSU and the PC worked perfectly for another 6 months, and then it blew up again.

I am very confused about how this could happen as the PC was under hardly any stress, as I was only browsing the web.

I have been told that it could be an issue with the 220v UK AC mains power and that it can be prevented in the future by fitting UPS device. To regulate the power going in to the PSU.

Regards Sean

The same people will see both. It is against forum rules to double post.

One thing I did notice is that your PSU has no voltage selector. I have no experience with that type of PSU. It is supposed to automatically adjust to the correct input voltage. If your wall sockets are not properly grounded then you could get a fluctuation in voltage. Just speculating.

Why don't you email Corsair?
