Is this a good power supply?

i believe i'm going to need a new power supply because i feel that i'm going find out that the reason for all of the problems i'm having with my comp is going to be the power supply.
(random BSODs and sometimes just random restarts with no messages at all, CPU is 100% stable and memory passes memtest)
anyways, i was looking at getting this power supply very soon due to the good deal that i can get on it
OCZ

is it a good one? or would it be wise for me to go with something a little more expensive in something like this...
Corsair

now i understand that the Corsair can't exactly be compared to it because there is a rather significant price difference, but i just want to know if the OCZ supply is a good one and i'll be fine with it.

my rig is the following:
Phenom II X4 810
ASUS M4A78T-E
Current PSU: Rosewill RP600V2-S-SL 600W (already been through one and i think this one is also bad)

4GB (2x2GB) Patriot DDR3 1333 memory 7-7-7-20
EVGA GTS 250 512MB
360&100GB HDDs

***also if you would like to suggest any to me, i would prefer it be modular...i hate cables
