What are your other parts in your pc. That should be enough if you don't have a threadripper or an i9.

I ran a 2700X and Vega FE off a 650W G3, I think the TXM series is a slight bit better (but not modular) and it should be plenty of wattage unless you have a really, really hungry CPU. They're dependable PSUs too, there's been one happily driving a rig I made for a friend (6700K/R9 290x, custom loop) since Christmas 2017 and it's had 0 issues or maintenance other than the one time he brought it over and I cleaned it up.

You're good, 1800X at top overclock on air/liquid draws about 150W, Vega 56 adds another 250w stock at most and 300w at most when core power limit and voltage are raised all the way up. Just don't be like GN and give the GPU a 400w power limit because it will then draw 500w

Yeah you should be fine then.

Wot. Stock Vega 56 is limited to 180W on core in the BIOS if I remember right, adjusting power limit allows you to go over that. 2-3 fans and HBM2 shouldn't use another 70W


My system uses 350W with 0.2 V undervolt at stock clocks

What's the rest?
How much Money?
Where do you live?

 

Personally I only have a Sapphire VEGA64 Nitro+ and that one is fine with most 450-550W PSU I have tried it.

The only ones to switch off so far were Seasonic G-550 and 450W Bitfenix Formula - the latter worked with 2 Rails on the GPU.

 

What I tried is:
Cougar GX-F 550W

Cougar LX500

Master Watt 550W

 

Some other units like Silverstone Strider Platinum, though 750W and the new ST-65F-GS were fine as well.

 

Normal Load Power is around 400-450W.with a Ryzen 7/1700x

 

Out of the Tested, the Master Watt 550W is disqualified because only one 8pin connection between GPU and PSU. And its screeching very loudly.

The LX500 is also screeching but less annoying than the Master Watt 550W.

just stopping the core from bouncing on the power limit like it's getting poked in the hole increases stock power draw a lot, I don't know if custom cards like the Strix has increased power limit from the factory. Undervolt helps but a) that's not stock and b) that limits overclocking
