Is my PSU OK for the 3080

Recommended Posts

Posted · Original PosterOP

Just looking to get opinions on whether I should upgrade my PSU for the 3080. I will NOT be over clocking. 

Case: NZXT H1

PSU: NZXT 650w gold 

 

CPU: Ryzen 3700x

Motherboard: Mini-ITX Rog Strix x570-i gaming

Storage: Sabrent M.2 pcie 3rd gen 2TB

Ram: Corsair LPX 3600 MHz 32GB 

AIO fan: Noctua IPPC 140mm 3000rpm fan 
AIO: 140mm that comes with the case 

 

currently eyeing the EVGA XC3 3080 for this build.

Estimated power draw would be 140W for the 3700X, 320W for the 3080 and 100W for the rest of the system. That's a total of 560W, so technically you can run it though your PSU might get a bit loud.

 

I'm assuming it's either the NZXT E Series or the C Series, both of which can run at full load without a doubt. I'd say you don't need a new one.

 

If your PSU model is something other than these two, then perhaps a change would be necessary.


We have a NEW and GLORIOUSER-ER-ER PSU Tier List Now. (dammit @LukeSavenije stop coming up with new ones)

You can check out the old one that gave joy to so many across the land here

Actuall, it's probably the SFX-L PSU that comes with the NZXT H1. Not sure about it, though it does have a 10-year warranty. Looks to be single rail.

 

@LukeSavenije got any dirt on this model? Here's the link

NP-S650M is the model number.

The NZXT NP-S650M = Seasonic SSR-650SGX from what I can tell.

I'm in a similar boat with a 650PSU (EVGA G2). Using this power supply calculator gave me a similar figure (575W load) for my components. This would peg my PSU running at 88% load. Are there any inherent disadvantages to running a PSU near it's max capacity?

650w G2 is plenty for the rtx 3080, as long as you arent running HEDT CPUs.

 

also dont use PSU calculators.
