[SOLVED] RX 580 or GTX 1070 for 450W PSU?

[alexcoulter111]

Hi,
I recently got a system without a gpu and am looking to upgrade it. I am deciding between an XFX RX 580 4GB and a Zotac GTX 1070. The cost is irrelevant. I just want to know which one will draw less power. Thanks.

Specs-
i7 4770K@stock
Stock cooler
ST45-SF-G (450W)
16gb 1600mhz
250gb ssd
Z77 mobo
2 fans
Raven rvz01

Power is near the bottom of these charts.

Personally 450W is a little tight.
