Hello all, I am new here 
I have bought a bundle from OCUK:
*OVERCLOCKED* Intel Core i7 930 2.80GHz @ 4.00GHz Max / Asus P6TD Deluxe Intel X58 (Socket 1366) DDR3 Motherboard / Corsair XMS3 6GB (3x2GB) DDR3 PC3-12800C9 (1600MHz) Tri-Channel DDR3 Bundle
I have a 3 HDD and 1 DVD-ROM, 1 DVD-RW and a few other little bits and bobs. It is also running a XFX GeForce 8800GTX.
I had problems with the system BSOD'ing when playing games (namely MS Flight Simulator X). These problems were solved when I de-clocked the system to stock speeds. So have been running at that since I bought it (it also hangs when trying to overclock on the fly using the supplied mobo software).
I believe that the problem could be due to my power supply. It was bought from ma-plin and is shown on the link below (remove the hyphen from the middle of ma-plin):

It provides 20A on the 12v rails and is 850w so should be more than sufficient. But it's not a well known make. Do you think this could be the problem in my system?
I was thinking of upgrading the PSU to the following corsair one:

Which would be a much better quality PSU. However would the wattage be sufficient? As I plan to upgrade my gfx card at a later date, maybe to a 5870 or similar.
Any help would be greatly appreciated, thanks.
