Posted May 10, 2021 So my friend is upgrading his GPU to a 3070. He has a 650w psu in there now with a 3900x. Neither the cpu nor GPU will be overclocked. Do you think that 650w is enough or does he need to get a new psu? Thanks Current Rig= AMD Ryzen 9 5900x, Asus Crosshair Hero VIII, EVGA RTX 3070 FTW3 ultra, 32gb Corsair Vengence Pro RGB 3000hz White, EVGA 750 P2 PSU, 1TB Samsung 980 Pro, 500gb samsung 860 evo, 250GB Samsung 850 evo, 2TB Samsung 970 Evo Plus, 2TB seagate firecuda sshd, LianLi PC 011 Dynamic XL ROG edition, Corsair h150i elite capelix Link to comment Share on other sites More sharing options...

Posted May 10, 2021 which 650w? (and for the love of everything holy dont just say something like "its a evga one" or "its a corsair one" say the modle!) I could use some help with this!

Posted May 10, 2021 Nvidia's official page recommends a 650w PSU, so they should be fine. Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...

Posted May 10, 2021 I would get a decent 750w for that scenario. Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...

Do you think that 650w is enough or does he need to get a new psu? Thanks Strictly from power recommendations from manufacturers, it meets the 'minimum requirement.' In the real-world, A pc with the 3900x and a 3070 probably won't suck up more than 400w stock. However, in the real-world, theoretical power output isn't the only concern. Please answer @HelpfulTechWizard's question. Your psu will need to deal with transient spikes.

People give a very vague description of what parts they have. I believe the power supply in his unit is a powerspec 650w 80+ gold. It is microcenters in house brand of power supplys.

If you want to be abundantly cautious, This isn't a bad practice, not nearly. However, It isn't required. For example, Optimum tech was able to run a 10900k @ 5.1ghz with 1.3v running through it, and 3080 TUF OC while playing Battlefield V at 4k high settings... On an sf600, without tripping the OPP due to transient spikes. Of course, that wasn't full-load, but it was fairly close on the GPU, and the 10900k draws massive amounts of power over TDP when overclocked like this. My point is that it isn't strictly necessary, and you can be totally fine without accounting for transient spikes. It will depend on the PSU, the model of which OP will hopefully provide.

I have built a few systems with them in it and they work really well for the price. Okay, let me get this out of the way: My knowledge about this PSU is quite limited, my advice may not be totally correct. Moving on: Minimum recommended system power for an rtx 3070 is 650w from Nvidia. This probably accounts for transient spikes in some shape or form. Now, I beileve that the powerspec psu that you mentioned uses an OEM for the actual unit, I can't provide anything else about that. In other words, I'm dubious about the quality of the PSU. However, it IS rated for OPP and has critical power protection ratings- at least in theory, from Microcenter's claims. I wouldn't imagine that they're lying, most likely. However, I haven't found a source that independently validates that, lol, mostly because I didn't do a ton of research about it. I would suggest that you guys try it out and see if say, the OPP trips under full cpu+gpu load. If it does, I'd probably recommend getting a new PSU, my recommendation would be the Enermax revolution D.F 850, should be $130 USD. If it doesn't, you still might want to keep upgrading in mind, it wouldn't be nearly a bad idea.
