is 450 watt enough for 1070 ROG ?

[Miiiinou]

i have a Corsair VS Series 450w PSU would it be able to run ASUS GeForce GTX 1070 8GB ROG STRIX OC Edition ?

Very risky esp. depending on the other components of your rig being powered by that poor-quality PSU. It's better to get a good-quality power supply to pair/complement high-end components. That VS 450 is intended for budget/entry-level rigs or office PCs. Personally, I would use a ~500W to ~550W good-quality PSU such as the Seasonic M12II-520 or the Corsair CX550M. If budget permits and you want more headroom and flexibility (in upgrades), I'd also consider the Seasonic G-550, EVGA SuperNOVA G2 550 or G3 550.

It's true that a 450W PSU can handle a GTX 1070 (along with other basic components), but, I would only risk it if the 450W is a good-quality PSU that is meant to last long, built very well, and has ample protection to not damage/destroy my PC, esp. if you are to max. out its performance.

If I was in your position, and have up to $80 to spend for a good-quality PSU, I will take a closer look at these highly-recommended great quality PSU models:
