I am looking to upgrade my gaming pc in February (2013), and I need to know if my current PSU will be good enough. I used the eXtreme Power Supply Calculator to figure out how much power I would need, and it came out at around 521, and my PSU is a 530w. My current system specs are:
Rosewill Challenger w/ 1x 120mm fan, 1x 120mm LED fan, and 1x 140mm fans
Raidmax Hybrid Semi Modular PSU 530w: http://www.newegg.com/Product/Product.aspx?Item=N82E168...
AMD Phenom x4 955 BE (stock cooler)
2x2GB Gskill RAM 1333mhz
ASUS GTX 550 ti
WD Caviar Green 1tb (5900rpm i think?)
Asrock Extreme3 970 mobo

and I would like to add:
AMD fx-8150
Corsair h-50 water cooler
2 more 2gb ram sticks
another ASUS GTX 550 Ti

So will my current PSU be able to handle this upgrade without getting replaced?

Nope, you won't be able to use your current PSU in an SLI set up. You'll want to look at a quality 700+W PSU for SLI.

Okay, minus the SLI, could I add an fx-8120, liquid cooling system, and 2x2gb more RAM?

EDIT: and actually, I just went here: http://www.realhardtechx.com/index_archivos/Page362.htm and looked at the PSU requirements for a 550ti SLI and it says 500w

Without SLI, you should be fine. The realhardtechx calculator is showing your suggested PSU for the system with one graphics card. You've got that covered. I'd love to tell you the 8120 won't cause any issues but I could find no legitimate reviews for your PSU (other than to see it is dual rail design) and the 8120 can pull up to 11A from one of those rails, there is a slight possibility of issues depending upon PSU design. I don't think you'll kill any of your components if you try it and it doesn't work out (but there is a slight risk) but it's something to be aware of
Hope it helps

You will be fine with a decent PSU in the 580-700w range from Corsair, Seasonic or XFX.

Don't break your head over the "minimum" specs of 500w required. My System is perfectly fine with a Corsair HX-650w and I still have room for a few drives and fans.

I can recommend the following PSUs:
Seasonic
