Enough power to run my computer?

[foxnamedfox]

This is my first time attempting to build my own pc, and was wondering if the psu I have chosen will be powerful enough to run the rig smoothly. Assume the 22 inch LED monitor and 500GB external HD I already have are plugged into the computer as well. Here goes:

COUGAR Evolution-W White SECC ATX Full Tower with one extra 2000 rpm LED fan

Intel Core i5-3570K Ivy Bridge 3.4GHz (3.8GHz Turbo) - OC'd to the turbo settings

COOLER MASTER Hyper 212 EVO RR-212E-20PK-R2 120mm Sleeve CPU Cooler

SAMSUNG 830 Series MZ-7PC128B/WW 2.5" 128GB SATA III MLC Internal Solid State Drive

EVGA SuperClocked GeForce GTX 660 Ti 2GB

SeaSonic M12II 620 Bronze 620W ATX12V V2.3 / EPS 12V V2.91 SLI Ready 80 PLUS BRONZE Certified Modular Active PFC Power Supply

ASUS DRW-24B1ST/BLK/B/AS Black SATA 24X DVD Burner

ASRock Z77 Extreme4 LGA 1155 Intel Z77 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard

CORSAIR Vengeance 8GB (2 x 4GB)


Thanks alot for any feedback/opinions/advice on the matter

It's plenty.

Remember your monitor doesn't plug into your computer
