6+8 pins PSU

[lioredrii]

I'm about to buy (upgrade my current GPU) Gigabyte Radeon R9 390 G1 Gaming, and i'm not sure whether my PSU is good enough or not.
my current PC is :
MOBO Gigabyte P55-US3L
CPU Intel i5 750 2.67Ghz
PSU : ZM600 GLX
8 Gb RAM
Sapphire Radeon HD 5770.
Yes, Iknow its ancient stuff, however my question is does this PSU gonna provide watt-wise, also, does it have the proper connections? (the 390 requiers 6+8 pins, but this PSU has only 2 eight pins and 0 six pins).
I'm a real scrub when it comes to this, thank you so much for helping me.

It should have two 6+2 pins PCI Express connectors; just unlatch the 2 pins connector on one connector. You already know the PSU isn't the greatest, but it's powerful enough.

Thank you for your comment.
So if I get it right your'e saying this PSU will do, and i don't HAVE to change, but i should, in the future?

I'd keep it until you build a better system. Since you have the PSU, have you checked the PCI Express connectors?

I think its labeled as PCIE 2.0 , guess the r9 390, which can utilize PCIE 3.0 would just run a little slower, would'nt it?

You won't notice the difference; the CPU will be the bottleneck in CPU intensive games.

Obviously, but with the current price, due to black friday/cyber monday i think it's best to invest and get this GPU for a long term.
not to forget though, Mantle is about to be established, therefore cpu bottlenecks would be much less common.
Also, my current cpu is just fine for the specific games I play (mostly Dota 2 and Fallout 4)
I appreciate your support so far. thank you so much.

Mantle is sort of dead; it's being replaced by DX12 that works with both AMD and NVidia GPUs.
