Oof, youre 100w off from the recommended psu capacity. An RTX 3070's recommended psu is 650w. 

With the transient spikes of RTX 30 series, there's no chance you'd be able to run it off of a 650w psu. 

Some of Linus's intel extreme upgrade series wuth 3080s  tried the 650w psu, James was one of them. He ended buying 850w psus.

Your system will use at max around 600W, so 650W is enough "technically"

 

However, you need a good PSU because such a load may either make it hot/noisy, or worse it may trip on GPU "power surges" that can make the GPU reach 500W+

To be on the safe side I'd suggest you get a good 850W PSU (say Corsair RMx, around $130)

The PSU sticker should have the name right... Like VS650 RM650 CS650 or something. 

Regardless, you need to upgrade your PSU, otherwise there would be shutdowns when youre putting the PC under load.

Real talk that PSU would likely be perfectly fine.  There's no point in "pre upgrading".  Just try it and if it clicks off at some point you need more.

LANRig/GuestGamingBox: 9900nonK || Gigabyte Z390 Master || ASUS TUF 3090 650W shunt || Corsair SF600 || CPU+GPU watercooled 280 rad pull only || whole-house loop.

Did they gave you all the cables with the PSU when you bought the system? 2 PCI-e cables with two 6+2 pin connectors each and a bunch of PATA and SATA cables?

This is a quality unit, don't replace it right away. If your 3080 ti runs stable without crashing, you can definitely stick with the RMX. The only real issue with the 30 series is the transient power draw, spikes that cause instability. If the unit can handle the spikes without issues, then no prob.

I WILL find your ITX build thread, and I WILL recommend the SIlverstone Sugo SG13B

 

Primary PC:

i7 8086k - EVGA Z370 Classified K - G.Skill Trident Z RGB - WD SN750 - Jedi Order Titan Xp - Hyper 212 Black (with RGB Riing flair) - EVGA G3 650W - dual booting Windows 10 and Linux - Black and green theme, Razer brainwashed me.

Draws 400 watts under max load, for reference.

 

How many watts do I need? ATX 3.0 & PCIe 5.0 spec, PSU misconceptions, protections explained, group reg is bad

Wow!  Surprised a pre-build has such a quality unit.

 

Here's what you do:  You upgrade the GPU.  If the PC shuts down, you know you need to upgrade to a higher wattage PSU.  Done.
