Will my system support this?

[_Grid21]

I am looking into replacing my 980 Ti FTW with a 30 series card, hopefully the 3070 when it comes out. But I need to know a few things first. My system is an Corsair H115i AIO, internal USB Hub, AMD Ryzen 7 2700, Asus ROG Strix X470-F GAMING Motherboard, 32GB of ram, 1 USB 3.0 Expansion Card, 1 Elgato HD60 Pro, 4 Hard Drives, 1 SSD, and basically all full USB ports but more importantly, a EVGA G2 SuperNova 750Watt PSU. Is a 750 Watt with 2 8-Pins GPU Plugs enough to power a 30 Series GPU, AND all the other devices plugged/wired into my computer? I didn't want to drop money till I knew for sure that a 3070 would be able to work and my other concern is that my PCIe is 3.0 not 4.0. 

 

Let me know and thanks in advance!

The 3070 FE only needs a single 8-pin. You could throw a 3090 in there and still be fine with 750W.

If PCIe 4.0 doesn't make a difference on the 3080, then it probably isn't going to on the 3070.

If you have other pcie devices, you can move them to the chipset lanes to ensure your GPU is getting x16 speeds

Other than that, no concerns

Replying to both of you, I just wanted to make sure I had a system was that was ready both in power supply, and also in CPU. I assume that my Ryzen 7 2700 isn't going to be a bottleneck for a 3070 right?

Short answer: don't worry about it
