I'm currently upgrading my PC. My previous build lasted 6 years and so I'm hoping my new one will also last quite a while. I've ordered an i7 8700k CPU, a Gigabyte Z370 Aorus Gaming 7 motherboard and 16GB of DDR4 RAM. However, I have a couple of questions:

1) Is it safe for me to reuse my Corsair TX 750W power supply, even though it was purchased back in 2011? Or would it be better to buy a new one?

2) I'm planning to buy a new monitor (2560 x 1440; 144Hz) at some point. I currently have a Geforce GTX 970 graphic card. Would I see any benefits buying a Geforce GTX 1080Ti, or would it be overkill for my build? Is there a card that would be a nice "middle ground"? I mostly play RPGs and some games like Resident Evil 7 and the latest Tomb Raider.

Thanks in advance for any opinions.
 
If your buying that monitor a 1080ti would smash games on ultra, if you want to save money a 1080 is fine even a 1070 would do. The money you save on a 1080ti could go towards a new psu Seasonic and super flower are recommended on here quite often.
 
Will match the rig nicely

I would go with a new psu. You can always keep the Corsair TX as a spare. A Seasonic Focus Gold would be my choice at the moment.

As mentioned above, you will do fine with a GTX 1070 - GTX 1080 ti depending on your budget. So middle ground would be the GTX 1080. Of course if you went with a Freesync 1440p monitor then you would be looking at a Vega 56 instead.
 
Thanks for all the responses. I’ve decided to put getting the monitor on hold and get the Seasonic power supply. If I get the Geforce GTX 1080Ti and also install an Asetek 570LX CPU Cooler with the build above, what wattage of power supply will I need? I will also be installing a Blu Ray drive, 250GB SSD and a 1TB SATA drive.

The 550W version should be enough, but for another £10 you might as well get the 650W for a bit of extra headroom.

It's certainly safe to use the old PSU but bear in mind at that age it may well not last another six years. PSU's can suddenly start developing irritating noises when they get very old too.
You would notice a HUGE difference going from GTX970 to a GTX1070, let alone a GTX1080. At 1080p a 1070 will run just about everything with ease, barely getting off ambient. But if you see this as lasting six years and you want to get that monitor above 60HZ ( which is, I assume, why you are buying it ) then get a GTX1080.
If you do want to go for a new PSU bear in mind that some PSU's now will not even turn the fan on until you get to above 40% load, so there is some advantage to having too much power. While a good quality 500W PSU would be fine I would actually recommend a 600W ~ 750W, since the price difference is small and you can often use less than that magic 40% so the unit is literally silent. Another factor is that if you are a monitoring nut, some Corsair PSU's allow you to monitor the internal goings on and even control the fan.
