500W PSU enough?

[pbcrazy]

I'm slowly piecing together a build to run Cad/Inventor/etc. (if I use for gaming, it will be games like portal 2 or something, not any high quality titles) by picking up items as I find them on sale, so far I've purchased:
Motherboard: ASUS A88X-PRO FM2+ / FM2 AMD A88X (Bolton D4) HDMI SATA 6Gb/s USB 3.0 ATX AMD ($57.99)
Case: NZXT Source 210 S210-001 ATX Mid Tower Computer Case ($29.99)
PSU: CORSAIR CX series CX500 500W ATX12V v2.3 80 PLUS BRONZE Certified ($26.99)
Case Fans: Cooler Master Sleeve Bearing 120mm Blue LED Silent Fan for Computer Cases ($5.99 for 2)

And I will be purchasing when I see them on sale:
Storage: 1TB Western Digital Blue HDD (or equivalent)
Memory: 2x4gb DDR3 1600mhz+
CPU: Amd A8-6600k (or A10 depending on price)

I will have 3 case fans with possibly adding a new CPU cooler (like a cooler master 212 or equivalent if on sale) as I've heard these APU's can run quite hot with the stock cooling. So does this build all match up and just to make sure, 500Watt will be plenty correct? I don't have intentions of running dual graphics or upgrading to 16gb, but may reconsider in the future as I get some money to play with it. Thank you!

That PSU is not the best quality but that computer will run perfectly safely on it.

400w would have been plenty here with no GPU.

Perfect, I know the PSU isn't the greatest but $3 instant coupon+$20 rebate definitely got my attention as it is better than most $20-40 PSUs from what I've seen. Thanks!
