Is a 600W Power supply good enough for a 3080?

Recommended Posts

Posted · Original PosterOP

Hello I’m looking to buy a RTX 3080 and I have a 600W power supply with a 5 3600 i’m wondering if that would work or if I need to upgrade because my system only really consumes around 100W or 200W.

Can buy the 3080 and see how it goes. 600W no good, then upgrade to a PSU with more wattage.

With a 3600 it should be about fine.  If it's a good model and relatively new it will be fine.  Reviews have shown that the entire system power draw of a 3080 + 3950x/10900k is about 500-520w or so, so you should be decently under that.


QUOTE ME IN A REPLY SO I CAN SEE THE NOTIFICATION!

When there is no danger of failure there is no pleasure in success.

What 600w PSU?


I am still TechWizardThatNeedsHelp, just less of a mouthfull.

 

My beautiful, but not that powerful, main PC:

My new PC I'm saving for:

  • NZXT H1 Matte Black
    • Comes with a 650W NZXT PSU
    • NZXT AIO
  • Ryzen 5 3600
  • MSI B450i GAMING PLUS AC
  • XPG ADATA 2800Mhz
  • RX480 untill I have more for a 2060 or 2070
  • 2tb Sabrent Rocket Q PCIE gen 3 NVME SSD
  • Samsung 470 128GB SATA SSD

3080 draws about 380W max. 3600 is around 90W max. A 600W PSU leaves you with only 130W for everything else in the system, which should be sufficient, but you're going to be pushing the efficiency curve past 80% on the PSU. For a good quality PSU, that's not much of an issue. Worse case scenario, you're just paying a little more on the light bill. However, a poor quality PSU or even just and older one on its last legs could crap out on you and/or potentially damage your components. It's always better to leave a little headroom. I'd personally say 650W would be floor for a system with a 3080, but 600W should be fine.

Wārudobītā

CPU: Ryzen 3 3100. Board: B550m TUF plus. Memory: 16 (2x8) 3200 cl16 Hyper x Fury RGB. GPU: Gigabyte Windforce 1650 super.  Boot Drive: MX500. Case: Antec NX500 (Quite crappy. :p) PSU: CX450. 

 

Hehe, Meshify c is a kewl case.

depends on how old the power supply is as well. A brand new 600W PSU can handle a 3080 as long as the rest of your system doesn't include a high-end Intel CPU.

 

BUT!!, over time a power supply will lose its potential with wear and tear under heavy load. It's been a long time since I've read any documentation on this, but iirc its good to assume that a year of continual heavy use will degrade a PSU by 5-10% of the total power it can deliver in a stable manner. So a 5 year old 600W PSU that's been used heavily might not be enough for a 3080, especially an AIB 3080. 

 

Food for thought. 

 

edit: forgot to add a couple points.

first, power supplies are most efficient at about 50% load. 

second, the power being drawn by a power hungry component might average 350 watts over time, but there might be large spikes that only last for milliseconds which could push a PSU to its limits.

I’m not sure I don’t have the box but it was around $50.

 

Open the side of the PC and look at it and tell us what it is.

You also need a new PSU and 750W.

 

The one you have is very poor quality.. Don't even think about running an RTX 3080 off that thing.

 

Pick something from Tier A or B:

 

Something like a Corsair RMX 750W.

EXTRMELY LOW QUALITY PSU.

 

Not made to handle more than just an email PC with no graphics card.

Return it if you can or throw it in the trash if not once you get the new PSU.

Yeah, that will work fine.

 

Can also look at the HX or HXI 750 or 850 and RMX 750 or 850.

 

Any of them are good.

So a quality PSU will allow you to push them above specification. However:

  1. The extra headroom is to compensate for normal wear of components over the years.
  2. Efficiency of the PSU will drop considerably as you pass the PSU limit more and more.

Ideally, you want a PSU where your system consumes on average, based on your usage, 50% of it's specifications which is the peek efficiency rating of the PSU. (The efficiency curve is in the shape of a hill)

 

Now onto your question: 600W should be enough if you don't OC anything. However, you are getting close to your your PSU max specifications.

Assuming you have a decent PSU, your PSU should automatically turn off if you draw too much power. So if your system turns off on you, it could be because of the PSU protection system engaged. Keep in mind that, frequency of a modern processor are not constant in speed and power requirements. If you OC, your system might seem fine, but if at random your system turns off, it could be a case where the CPU and GPU both, at a fraction of second, clocked very high, requiring more power, and your PSU protection system triggered. So if you use a meter on the wall to see your power consumption, it doesn't go fast enough to really see a spike of say 400W to 620W. So anyway, all to say, if your system turns off on you, and temps are not the issue, then it could be this, despite what a wall meter might indicate.

Ideally yeah, true, but we normally get one heck of a lot of pushback around here if we recommend anything remotely close to that. 🙄

 

We typically see 85% or higher load range recommendations around here.... (A lot of PUSHBACK).... My opinions on that are pretty well known.... So I won't go into it here.. 🙄

 

I usually recommend something in the 65% range or so....

 

But yeah that 40% to 65% range is ideal depending on the PSU, have to look at the actual model to see what it is..
