550W enough for RTX 3070?

[Extrremee]

As the title says;

PSU: Seasonic Focus GX-550 80+ Gold

 

CPU: R5 3600

Prospective GPU: Gigabyte GeForce RTX 3070 GAMING OC 8GB

 

From various sources I've seen this card go from 270W-302W.

The math, and various calculators say that the power draw is around 475W and recommending 500W.

 

Thanks for any advice!

In theory it should work although I would strongly recommend against doing it as you could trigger the overcurrent protection on the power supply which would mean that your PC would shutdown randomly.

Would it be safe to try?

 

If I need a better PSU I'll get one, but...

if you have a hard disk in your system then I would take that out while doing testing as random power losses can affect hard disks. But the rest of your components will probably be fine. I would also recommend temporarily using Linux as windows gets confused when doing testing like this.

also have a look at this thread its very similar to what your saying:

That sounds a little excessive for a 3070.

 

Especially considering that you're only pairing it with a CPU that pulls 70-80W max, you should be fine with your current PSU.

If you already have the PSU though, then you might as well try it. If it does end up not working out, you can lower the power limit and/or undervolt the GPU, and then get a slightly beefier PSU.

You're saying it like protections aren't there specifically to prevent damage from occuring.

I only have an SSD

So I should be safe to at least attempt boot, and even some use with my current 550W?

I don't see why you wouldn't be.

I guess if he had a hard disk it could kill it
