This is my PSU. Note that it's the highest Wattage PSU that I can fit in my case so I really have no choice for upgrades on this.

Things that draw power:

2 Sticks DDR3 Ram
H77 Motherboard
Core i3 3245
1 CD Drive
1 HDD
1 SSD
2 Case Fans
1 CPU stock heatsink
8 USB devices

For the Video Card I'm thinking of upgrading my Radeon 7770 to a 7950.

Is it gonna work?

If it won't work, what's the best card I can fit in there? Would a GTX 760 work? Or Radeon 7870 Ghz edition?

I was thinking I may barely be able to make it though.

i3 draws like 70 watts
7950 draws 200 watts
add in 100 watts for everything else only gets up to 370

Or am I missing something?

I like my case a lot so I'm not gonna switch. What's the best card you'd recommend then?
