Is my PSU good enough to handle it for now or not? Because at this moment I do not have the money to buy another PSU. Thanks...

The wattage is enough, but we do not know the PSU model to know if it's a reliable unit.

No, you will need a better model than that, that's really a 504W PSU.

And has 2x 6+2 pin PCIe connections on 2 separate cables and at least 550W.

The minimum required for the EVGA GeForce GTX 1070 Ti FTW2 is a 500 Watt power supply.
Even though a 500W unit could supply the power that system requires, that unit might not be able to handle new systems power states.
I suggest you get a current designed 80+ Gold semi/fully modular power supply.
Models like Seasonic Prime/Focus, EVGA G3, Corsair RMx/TX-M//RMi series.

I actually don't see why not.A review with it that uses "only" about 333watt with this gpu.
https://www.anandtech.com/show/12373/the-evga-geforce-gtx-1070-ti-ftw2-review/15
Contains a Intel Core i7-7820X @3.4ghz which does use alot of power as well.

Vic 40 :

The issue is not with the wattage, since a 500W PSU could handle the system power requirement.
New CPUs from AMD and Intel have deeper, lower power sleep states (c6/c7) which translate into better efficiency than older platforms.
If the PSU is not able to handle those states, the system will freeze instead of entering sleep mode. The system could also refuse to wake up from sleep or it will wake up from sleep without user interaction.
Sometimes, those states (c6/c7) could be disable in the BIOS and then it might not be an issue.
