That's the one

Replace it with a newer unit, the new Grey labeled (2017) units are a lot better. Preferably TXM or CXM or RMx.

What PSU would you recommend? And what do you think about the CPU? i5 7500 or i7 7700? And if 7700 then K or regular?
 


Personally I use Seasonic, The Focus 750W Gold or Prime 750W Gold are nice.

I would get the 7700K, faster and you can OC it.

Unfortunately we don't have it in my country. What do you think about the Corsair RM750x 750W PSU 80+ Gold Modular?
 


That's a good one. :D

Nice Tier 1 PSU.

So I should be good to go with that Corsair RM750X along with the i7700k (no OC) and the GTX 1080 ti?
 


Yes, no issues. :D
 
Okay, lots of things here.

1) Corsair CSM units are actually better than the new Corsair CXM units. CSM were always good - they were just overpriced. They were never bad. Made by Great Wall, good build quality, DC-DC, and higher efficiency.

2) Corsair AF LED fans are quite bad in my experience. Don't vertically mount them, they have sleeve bearings.

3) You don't need a 750W PSU, a 550W will do.

Okay, so what would you recommend me to change?
 


I think the RMx is a great choice. I'm just saying you can save money with the 550W, but 750W works, too, if you want that one.

What about the fans?
 


Noctua likely makes the best ones, but they don't have LED options.

Look at NZXT fans.

Dammit, no NZXT fans in my country either. And the Noctua really are ugly haha What do you think about the Corsair ML120 PRO LED Red 120mm PWM Premium Magnetic Levitation Fan?
