I would suggest upgrading your PSU at this stage - it is low quality and you are running quite a bit off it.
A higher quality one such as this would do fine: Newegg.com - CORSAIR CMPSU-750TX 750W ATX12V / EPS12V SLI Ready CrossFire Ready 80 PLUS Certified Active PFC Compatible with Core i7 Power Supply
Or, if you are planning big upgrades in the near future - Newegg.com - CORSAIR CMPSU-850TX 850W ATX12V 2.2 / EPS12V 2.91 SLI Ready CrossFire Ready Active PFC Power
EDIT: Of course - it could just be a problem with your SSD - given that it is so new. You may want to try it out in another system.
