is a 650w 80+ Bronze PSU with a Ryzen 5 5600x and a RTX 3080 fine?

Is a EVGA BQ 650w 80+ Bronze PSU fine for an RTX 3080 and a Ryzen 5 5600x? or should i just get an RTX 3070?

No min PSU 850W Gold or Platin. Better is a PSU 1000W Gold or Platin.
I have a Gainward RTX 3090 Phantom GS with PSU 1250W Gold.
My 850W PSU has at RTX 3090 max power shot dawn.

RTX 3080 has a MINIMUM 750W PSU listed by Nvidia

Nvidia recommends 750 Watt PSU for the Rtx 3080 but 650 watt will do the job. Your CPU is not very power hungry, that's an advantage for you. If it were an intel CPU like the 10700K / 10850k, it would pull around 100 watts more power (more if OCed). So you should be fine.

Minimum? I think it was recommended as worst case with a high tdp cpu. 5600x is clearly not a high tdp cpu but these recommendations are for FE model which has a very low powerlimit. Dont know which card op wants to buy. We have FE with 320w and we have something like strix/ftw3 with 450w.

[_I_]

3080 is 320w
+100w cpu
+100w mobo+drives+fans+usb etc...
+100w overhead

= 620w minimum with a quality psu

nvidia lists 750w to cover lower quality overrated psus

evga 650w should be able to run it, but its never good to run a psu at max output for long periods of time

psus efficiency drops over 90% load
most are best around 50-70% loads

520w (load) / 70% (load efficency) = 742w (psu rating)

If you already have it, it should be fine, if you need to buy it... It go for an 850w to remain more in line with peak efficency.

My 9900k and 3090FE only pull around 600w from the wall OC'd, it'll only pull crazy power if you power mod the cards, then the 3080/90 could pull upto around 7-800w, if your not doing that 850w is plenty unless you also run a high end cpu (doesn't apply to op) or one of the new TEC coolers.

650W should be fine with a 5600X and 3080, the recommendation came with the expectation that some users would be using higher TDP chips like the 5800X, 10700K, etc.

not at all.

NV says 750 min, and thats an outright lie.

You can get by with marginal stability (good enough for benchmarks and such, but you will likely see issues in long term daily use) with an 850...

If it were my personal build I would use a minimum 950w gold from a good company or with good internal build reviews from third parties.

My System:
ASUS ROG MAXIMUS XI Hero
Intel(R) Core(TM) i9-9900KF
Corsair 32GB DDR4 3200Mhz
2x Samsung 970 EVO Plus (M2 SSD 1TB)
Gainward RTX 3090 Phantom GS

With a 850W PSU i play Cyberpunk 2077 two hours than shot down the PSU.
With a 1250W PSU not more schot down.

How's it a lie when the system wont pull near that really? Under normal use, so no power modding or bios mods, their recommendations are more than enough power.

Seriously alot of people on this forum need to buy a power meter to plug into to get a clue about how much power their systems actually use.

Then it's an issue with the psu itself, not the wattage as you aren't pulling near that much power, also, it would shut off immidietly not after 2 hours if it was just pulling too much power.

Nv didnt say min and benchmarks pull less power then "long term daily use" (whatever this is)? Looks like you use wrong bechmarks which doesnt stress your hardware and you have no clue how much your system realy uses. Its very hard to push above 750w with only 1 3080 and a low tdp cpu like op has. I would say its impossible.

The combined power consumption of a 5600X and 3080 is only going to be around 450~500W at most. It's fine for a 650W PSU unless the OP has more than a few hard drives, fans, etc. that are also drawing from the +12V rail.

If he were using a 105W Ryzen processor or an overclocked Intel K CPU like the 10900K then I would recommend at least 750.

[Nabster]

No, a mediocre bq can't deal with the power spike of a 3080.

get a Supernova gold 750+.

3080 is 320w

Wait, it is? ♥♥♥♥♥♥♥♥♥ wtf happened
