Do I need to replace my PSU for these upgrades?

[Eran Machlev]

Hey, I will buy new PC parts soon and I want to know if I should replace my Corsair CX500 PSU with a new one -

Here are my upgrades -

Replacing - Intel Core i5-2300
With - Intel Core i5-4670k (Overclock to 4.5Ghz)

Replacing - Kingston ValueRam 2*2GB DDR3-1333
With - Corsair 2x4GB XMS3 DDR3 1333

Replacing - Intel DH67BL Motherboard
With - Gigabyte GA-Z97-HD3 Motherboard

Replacing - Stock i5-4670k CPU cooler
With - Noctua NH-U14S

I have an AMD Radeon HD 7770 GPU overclocked with a +10% power limit.

Thanks.

You should replace your PSU as you want to overclock the CPU. With more watts you can also overclock your GPU further.

What if I overclock it to 4.2 or 4.0?

You'll be completely fine at 4.5, according to this.

If you don't mind me comparing it to ivy procs, they use about 40% more than normal when overclocked according to anand.

So the GPU's 150W power consumption, plus the 162W from the CPU, it's 312W.
Does it leave enough room for the RAM, MOBO and CPU cooler?

Yeah you're fine. Those things only use maybe up 30w in total.
