Hi,
I have Zalman ZM450-FX (SFX PSU), 80+ Bronze, 36A on 12v rail - http://www.zalman.com/eng/product/Product_Read.php?Idx=924

And the GPU I am planning to get is: SAPPHIRE NITRO Radeon R9 380

Will the PSU be able to run the graphic card, if I am going to overclock it (without changing core voltage)?

Other components:
CPU: i5-4460
RAM: 2x4 GB DDR3
Storage: 1 TB HDD
Storage: 120 GB SSD
Motherboard: MSI Z87I Gaming AC

it should. the 380 is not a 500w gpu though. but if i'm in your boots i'd be a little worried because i might be pushing the PSU a little near it's limit. i remember my 280x making my corsair gs600 a bit hotter than what i'm comfortable with so i sold it. i'm using gtx960 right now and the difference in the heat in the PSU is night and day.

it wouldn't hurt upgrading the PSU as well.
