Depending on where I go, each online calculator gives me a different number. I plan on upgrading my PC soon and I need to know If My power supply can handle the extra components.

Right now I have:

Corsair HX850 PSU
Asrock Z77 Extreme6 Motherboard
Intel Core i7 3770k @ 4.2 Ghz
16GB DDR3 RAM (2 sticks)
128GB Intel 330 Series SSD (Boot)
1TB Western Digital Blue HDD (Data)
Corsair H100i
Creative Sound Blaster Recon 3D Fatal1ty Edition (no front bay)
MSI GTX 670 Power Edition
DVD RW Drive
1 200mm LED fan
2 120mm static pressure fans
1 120mm high airflow fan
Fan controller (built into case)


I plan on adding another 670 Power edition, and possibly a Blu-Ray Drive and/or another hard drive. I don't want to get anything just to find out that my power supply can't handle it; I also don't want to buy a new power supply if I don't have to.

Thanks in advance!

You wont have any problems with that power supply. I have 2x 770's (basically OC'ed 680's) running on a 850 watt with no issue. Also Corsair is a good PSU brand as well.
