Splendid. Yes it is enough. 400W is recommended minimum. Your GTX 645 uses slightly more power than a GTX 1060.

Furthermore, is 460 watt power supply enough for GTX 1080?

Ive searched other threads and subreddits and most people seem to say that a 460 is fine for powering the 1080, and that at most the computer will only be drawing ~280 watts. It should be enough, but that's really cutting it closer than I'd want to. You may not have much upgradability.

Additionally, is 500W good for power supply? Most of these you can get new for about 40 dollars on Amazon is it a good deal or would 600-750 watt be more appropriate. 500W is plenty for the majority of builds. Unless you have a GTX 1080 ti, Vega 56/64, or an older high-end AMD card, it's almost always enough.

Considering this, is a 750 watt power supply enough?

Generally speaking, a 750W PSU is enough for a high-end PC build. Some online stores give us a small cut if you buy something through one of our links.

Can a 450W PSU handle a 1080?

Conclusion. We wouldn't recommend a 450W PSU for the 7700K + GTX 1080 combo, but it works for most the other configurations on the bench. Running the higher-end combinations at 100% GPU / 100% CPU would strain the PSU in more significant ways, and would be better suited in the ~45-60% range on the utilization curve.

Can a 500W power supply run a 1080 TI?

If you have a 500W PSU already, and it is decent quality, it is easily enough for a 1080 Ti if you don't overclock heavily. 1080 Ti = 250 W, CPU = 65 W, everything else = 75 W. Total maximum is 390 W, which is well within the PSU's capability.
