Is my PSU enough to handle an OC?

[Bloodstriker]

I originally had my system OC'ed to 3.38GHz, but then I added a bunch of extra stuff and to be safe, I set it back to factory settings.

Now I'm not sure if the PSU can handle the new stuff I added with an OC. (added BD Burner, 2 HDD, 1 SSD, 2 120mm fans)

Here's my current build:

i7 920 C0 w/ Ultra 120 (want to OC to 3.48GHz, Vcore @ 1.25)
Enermax Infiniti 650W
3x2GB DDR3 1333
Sapphire HD 4870 1G
DVD/CD Combo Burner
BD/DVD/CD Combo Burner
3x1 TB SATA HDD @ 7200RPM
1x80GB Intel SSD
Logitech G15 KB with G9 Mouse
5 x 120mm Fans (4 case, 1 on CPU Cooler)

No LEDs or other stuff like that.

I checked those online power supply calculators and they're showing me that I need 500W, but I'm not sure how accurate/specific those really are.

You'll do just fine.

That 500 sounds about right; the major power draws in a system are from the GPU and CPU, which in your case would pull about a 450w draw at 100% load on both simultaneously. Fans and hdds and optical drives do pull power, but not nearly that much. Your OC will be fine, even if you somehow managed to keep your system at max load.

Not to mention, to my knowledge, Enermax units are usually quite good. Especially that one.

Whew. Thanks for the help - saved me $300 as I was thinking of pulling the trigger on the Corsair AX-1200 (overkill, but I thought I might as well spend the extra $100 and save to hassle of having to keep re-doing the cables.)
