Is my PSU sufficient enough?

I have had this build for a while now and I never really thought about this. But here are all the components in my PC. Does my PSU have high enough wattage?

PSU: OCZ ModXStream Pro 600W Modular High Performance Power Supply compatible with Intel Sandybridge Core i3 i5 i7 and AMD Phenom

MOBO: MSI 760GM-P33 AM3 AMD 760G Micro ATX AMD Motherboard

GPU: EVGA 01G-P3-1366-TR GeForce GTX 460 SE (Fermi) 1GB 256-bit GDDR5 PCI Express 2.0 x16 HDCP Ready SLI Support Video Card

CPU: AMD Phenom II X4 840 3.2GHz Socket AM3 95W Quad-Core Desktop Processor HDX840WFGMBOX
¬Yes, I know the PSU says it supports Phenom. But I have a Phenom II.(If that matters..?)

HDD: Seagate Barracuda 7200.12 ST3250318AS 250GB 7200 RPM SATA 3.0Gb/s 3.5" Internal Hard Drive -Bare Drive

Memory: G.SKILL Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL9D-4GBRL

Optical Drive: ASUS DRW-24B1ST/BLK/B/AS Black SATA 24X DVD Burner - Bulk - OEM
