Upgrades in my old system

[SKRDPTSGL]

This is what i'm thinking to do https://pcpartpicker.com/list/ using parts of my 7 years old pc(case,psu,cooler(?),ram(?),gpu,sound card) and new cpu,mobo,ram and cooler if my old doesn't fit.So i have some questions for you.

1.How soon you think psu(Superflower golden green HX 80+gold 750 watt) will die?

2.It's necessary to change my old ram(Corsair vengeance lpx 2400 Mhz Cl 14 64gb)?

3.My mobo(Rog strix Z270F gaming) supports NVIDIA 2 way SLI technology but is there a 4 to 6 GB GPU that can work combined with my old(GTX 1080 MSI gaming x 8GB) GPU?

If you have some suggestions or corrections to make please do it

Thank you!

As mentioned above, your list is empty.

I don't know what platform it is you were planning to go with, but anything recent that uses DDR4 (LGA 1700 or later AM4 generations) would want much faster RAM than that, like 3,200 MHz to 3,600 MHz.

You can only use SLI to pair the same GPU. If your current card is a GTX 1080, you'd need another GTX 1080 (it doesn't have to be exactly the same GTX 1080, but it needs to be a GTX 1080, not a 1080 Ti, not a 1060, etc.). In any case, multi-graphics card configurations are more or less "dead" these days, so I wouldn't recommend opting into it. A single card that costs whatever two GTX 1080s are worth would probably be better all around, as it would likely have better performance on average, and use less power and thus create less heat, leading to lower noise too.

Any part can fail at any time, but if you believe the 750W PSU is good (a good quality one at seven years should have little concern in my mind), then using it is fine.
