Would my Power Supply be sufficient for my setup?

Hello everyone!

I am planning to add an MSI 1070 ARMOR OC to my setup, and was wondering if my EVGA 650 G2 would be able to supply enough power.

My current setup is as follows:
CPU: i7-2700k
RAM: 4x4GB DDR3-1600 Corsair Vengeance
MB: GA-Z77-D3H (1.1)
GPU: Gigabyte G1 RX470 (I am planning on adding the 1070 to this, not replacing it)
Storage: Two SATA SSDs, and two 7.2k RPM SATA harddrives
Non-core components:
-a DVD drive
-a few case fans
-a few USB 3.0/2.0 devices

Whenever I run stress tests on my current system (without the 1070), it usually peaks around 400 watts from the wall (read using a killawatt). The MSI website for the card claims that it would pull about 150W.

I think I have enough headroom in my PSU limit, but I want to be sure.

Any input is greatly appreciated! :)

Heck yeah. The GTX 1070 will only draw an extra 30W over your RX-470. And that's only if the i7-2700K can max it out. I'm a little surprised that your system stressed draws 400W. Must be running Furmark and Prime95 together?

Yeah 400W is the absolute worst case with both of those running like you said. Just wanted to be sure before I buy. Thanks for the info!
