It will be pushing the PSU to the limit.
Which I don't recommend doing. Especially with that PSU

I highly doubt it but you can try

It can barely run it but get a 750 Watt PSU at least because of the power spikes of 30 series cards. It would run ,but it would just shut off under load because of power spikes that trip OCP

Or it could make the fun sparks and smells if it has the Gigabyte permanent kind of OCP

Yeah about that, I am running a 3070 on a old stock 7 year old (old stock, got it brand new this year) seasonic PSU with just 650w rating on 12v. Did not trigger OCP not once even though card is overclocked. Quality != Wattage.

In my experience 550W is more than enough for a RTX 3070. In fact, it's what Guru3D recommends.

 

Personally, I've been running my 550W Seasonic Prime Ultra for the last 2+ years on a RTX 3070 Founders. My meter at the outlet read 405W at full-tilt (100% load on GPU and CPU), including 1 of my displays, 1x M.2 SSD, 3x SATA SSDs, 1x SSHD, and 5 fans. This was on a 5600X and RTX 3070 Founders simultaneously running the stress tests in OCCT and Furmark.

If you pair it with ryzen 5600 it will be enough.

Its pushing the edge but should be okay

I ran a 2080 and a 3700x on a 550W PSU for a while. I wouldn't recommend it but I did it. 

[Moonzy]

i am currently typing (and gaming) on a 3900x + 3080ti rig, powered by a CX550M PSU

 

no shutdowns in the couple months i've used it _{i really should swap my HX1000 in, lazy af}

this is really not how it works, the deciding factor is the overall quality and transient power spikes handling,  which i doubt OPs unit is any good at,  but generally 550w should be plenty. 

 

I can run my setup 3060+3070 with a bequiet 500w no problems whatsoever for example. 

 

But yeah, OP should def get a better psu, 750w is way overkill though,  my corsair RMI 650 uses 500w *max* and that's with Prime95 + Superposition running at the same time...
