Question Is a 750W PSU enough for handling a 4070 Ti SUPER or a 4080S, and will there be any bottleneck issues with my 7600X?

Hello everyone, I'm currently deciding between a 4070tiS and a 4080S for gaming at 1440p with maximum settings over the next 5 years. I initially considered the 4070S, but the limited VRAM raised some concerns. Can my existing components effectively support either of these GPUs?

yep they'll be fine. both are supported. the PSU is plenty and there doesn't seem to be any bottlenecks either.

regarding GPU, VRAM is essential, and you should opt for a higher VRAM if you're gonna keep it for 5 years.

Thank you. I was worried that my PSU wouldn't be able to handle the 4080s. Nevertheless, do you recommend upgrading to a higher-wattage PSU if feasible?

750W is plenty, though if you like, you can opt for a higher wattage. There's plenty of headroom wattage left for the system to function properly.

My friend who owns a pc shop has advised me to go for 850w gold rated PSU or preferably a 1000w one in case of potential power spikes. I'm not sure what to believe now.

"potential power spikes", yes. power spikes happen, but they are somewhere near the max wattage draw of the GPU. Adding all the max power draws of the components and leaving some headroom of about 150W you'll be fine. 850W wouldn't be overkill, it will suit for even an upgrade in the future as well.

1000W is overkill

An ATX3.0 unit can handle powerspikes up to 200%. 850w unit is plenty for any single GPU system/ https://uk.pcpartpicker.com/product...ully-modular-atx-power-supply-mpg-a850g-pcie5 is a lot better than a Corsair RMe and only 4 ish more expensive.
