Is My 700w Power Supply enough for a RTX 3080?

Vanquish

Hey Everyone,

 

My PC has the following PSU: EVGA 700 GD 700W 80+ Gold

 

Would this power supply be enough to run a RTX 3080? 

 

Other PC specs below:

Motherboard

H370 AORUS (4x DDR4) (2x M.2 NVMe)

CPU

Intel Core i7-9700 

RAM

16GB DDR4 2666Mhz

I would highly recommend you get at the min a 750W high quality PSU.

 

The EVGA G3 or G5, or the G2.

 

Or a Corsair RMX or RM.

So according to Anandtech the i7-9700 uses about 165W at max. 
The RTX 3080 seems to draw at max ~330W, per gamers nexus
So 165 + 330 = 495
495/700 =.70

So you should be fine. 
EDIT: as pointed out below, this is only valid if you are using a RTX 3080 at stock. Don't expect to run any fancy, super-OC versions

Depends on the which RTX 3080 it is...

 

Some of them draw 450W...

Really guys? Do you really believe that your computer will need 800W PSU?

I hope you don't must pay your own bills, because 800W is the same amount of power like 8 x 100 W bulb. It's only twice less than vacuum or washing machine.

Higher margin is of course good thing, but don't ask OP to change his PSU if it's fine. After all it's not your money and bad advices costs.

False...

 

You could have a 10K watt PSU and if it only needs to supply 600W that's all it will supply.

 

MY system below pulls 630W+ gaming and 715W+ max load. And that is not from the wall...

 

NOT including power spikes.

But then he would need more than just 750W...

Yes, for those he would need an 850W Min.

Thanks for sharing information that was not only not helpful to the discussion, but you wasted 20 seconds of peoples time reading that :P If you are trying to be helpful, say something Actually helpful. Computers are getting more power hungry every year, there are efficient built computers that can barely sip Power and run fine, and then there are some pretty beastly units that will EASILY pull more then 800W-1000W with just the CPU And GPU.  The 3080 is one of those beastly units that can easily draw 350-440 watts depending on the card and power limit. 

 

@Vanquish With your Current system, i dont expect a 700W PSU to fail, IF that 700W psu is actually a 700W PSU :P If you got a Prebuilt and its using a Cheap PSU thats "rated" for 700 watts, theres a pretty damn good chance its not going to like running anything beyond 500-600 watts. The GPU alone is going to be pushing 350+ Watts, The rest of your system is more then likely going to draw 200W total, so id expect 550W. You should Technically be fine, but if you run into issues where under load its just suddenly powering off and you hear an audible click coming from your power supply, you then know its not a proper 700W unit.

From the rest of his system he really wouldnt, but that requries the PSU to be a fully functional 750W PSU and not having any qualms running at 500-600 Watts

It's a good point that since he has a good quality PSU, the worst that is likely to happen is the PC crashing under load.
So it's worth giving it a shot, and if you see this happening, then that means you need a bigger PSU.

or that the PSU is transiense sensetive. 

 

which wouldnt indicate a need for higher wattage. because a 700w unit should be just fine for the system described. tho the EVGA GD isnt a great unit, so getting a better unit would likely be a good idea.
