Hi, I'm building my first pc and I want to know if these are good specs for mostlly gaming. Also I plan to overclock so is this a good PSU. Lastly will I need a aftermarket cooler?

Firstly you can't overclock with a motherboard with the B75 chipset. So unless you change the motherboard to something with a Z77 chipset set, then you might as well get a locked CPU, such as i5-3550. And not bother with an aftermarket CPU cooler, unless you prefer to have a quieter system.

The XFX 550W Core Edition is a good enough PSU.
I think either of these is better, because they are independantly regulated (XFX is group regulated), so voltage regulation is better and one of them is modular, the other one is quieter.

Asking because on partpicker it says estimate is 378w no overclock? I though over clocking increases wattage alot.

P.S. I just dont want it to be to low and F**K up
