Question Can my PSU handle GTX 1070

[unknownmercyy]

I ordered GTX 1070 yesterday, but I own a Corsair CX450 450W PSU.
I used a PSU calculator to calculate the usage of my parts and i got 453W.

Should I stick with my current PSU (can I use it for a month or two) , or should I upgrade immediately

Thats my current setup and the info of the calculator:

Calculators way over estimate , a decent 550w would be ideal.

ALWAYS try to stick around 100W above what the calculator estimates.
Also the official NVIDIA website states that the 1070 has to have a minimum 500W system requirement:

In my opinion you should go for a 650 W or better a 750 W, they don't cost a lot more but that will allow you more upgrade-ability in the future (if you're planning some day) without needing to swap the PSU again.
However, if you're on a budget, that's fine too a 550W will do just fine.
