Is my PSU Sufficient for my setup?

[cassini_huygens]

Hello everybody,
I know I posted a thread very similar to this the other day, but a better card went on sale for the same price.

I wanted to add an MSI 1070 Ti Gaming to my setup, and was wondering if my EVGA 650 G2 would be sufficient enough to power it along with the rest of the stuff below.

CPU: i7-2700k (1.33V)
RAM: 4x4GB Corsair DDR3-1600 Vengeance
Current GPU: Gigabyte G1 RX470 (I would be adding the 1070 Ti to this, NOT replacing)
MB: GA-Z77-D3H
Storage: Two SATA SSDs, and two 7.2k RPM SATA HDDs
Additional things:
-DVD optical drive
-About 6 USB 3.0/2.0 devices
-5 case fans (molex)

When I max the GPU fans out and use a slight power overkill GPU OC along with the CPU OC (24/7), the system pulls a maximum of 430 watts from the wall (running FurMark's fuzzy donut and Prime95 SmallFTTs at the same time).

Thank you all for any input or recommendations!

If you will have them both RX470 and 1070 Ti then you need minimum 700W
The EVGA G2 is very good and it might be able to handle the load but I would go for 850W just in case.

Your PSU will problably be enough to power that configuration. The question is, for how long?
Best choice would be to go for a good psu like Seasonic PRIME FOCUS Gold 850w, to be on the save side.

Question-how and why are you adding a 2nd card rather than replacing the 470 all together?

I would be using the new card as a dedicated mining card (just want to have some fun).

I usually run games for a few hours during the day. The 430 watts is the absolute peak I could get my hardware to pull, I usually use 200-350 watts for day to day tasks.

When you power up your PC your devices, specially GPUs, will draw as much power as their rated peak power.
It does lasts for only a fraction of a second but that is all it takes for a PSU to go out of commission.

What are some good 750-850 watt power supplies that you'd suggest?
If I do end up getting the card listed, then I'd probably sell my current PSU since it's only a year old or so.

The same EVGA model you have. The EVGA G2 are pretty good, specially the 850W version
