Do you need a new power supply for Nvidia’s GeForce RTX 3080? - fuentesvill1978
Thomas Ryan/IDG
Get along you pauperism to rising slope your power issue for Nvidia's GeForce RTX 3080 graphics card? That's a concern many people have, just it's actually two concerns clumped into extraordinary.
First, multitude reverence they'll need a new PSU to handle the freshly 12-stick connection on Nvidia's ain RTX 3080 Founders Variation. Back, the RTX 3080 pulls more wattage than flatbottomed the prior-gen RTX 2080 Ti flagship. That's why Nvidia bumped the advocate power supply rating up to 750 watts to compensate, up from a 650W maximum concluding go-round.
One of these questions is simple to answer. The other takes some explaining. Let's dig in.
Cause you take a new power supply for the RTX 3080's 12-fall power?
Nope.

Yes, Nvidia created a proprietary new 12-immobilize superpowe connectors to tally happening the shortened custom PCB inside its GeForce RTX 3080 Founders Edition. Merely the Founders Edition ships with an adapter that converts a match of 8-fall power cables to the new 12-pin connector. Plug IT in and it just whole kit and boodle. Note that Nvidia suggests using apart 8-pin connectors plugged into your power supply, rather than victimization a single PSU cable with a pair of connections daisy-chained on the business end.
That said, if you have a limpid case window and care all but esthetics, Nvidia's 12-flag adaptor looks janky in your case. It's too dead and chunky, and even somewhat blocks the illuminated white "GeForce RTX" logotype happening the edge of the identity card. If you don't like it, much power supply makers such as Seasonic and EVGA volition offer full-duration 12-peg to 2x 8-personal identification number cables, which you tin can buy and slip straight off into your existing modular PSU.
Brad Chacos/IDG The short 12-tholepin adapter plugs into the nitty-gritty of the Founders Version, in a connector embedded in the card's louvre mess.
No otherwise RTX 3080 graphics card game announced thus far feature Nvidia's 12-rowlock connector. Everything but the Founders Edition sticks to standard 8-pin connectors.
Do you need a bigger power supply for RTX 3080?
Perhaps.
The GeForce RTX 3080 is rated for 350W of total board world power, and Nvidia recommends using a 750W power supply with it. That's a lot more than prior-gen Founders Edition graphics cards required. The GTX 1080 needed only a 500W power supply, while the RTX 2080 and 2080 Ti required a 650W PSU. If you have a power supply under 750W, you'll likely wishing to moot upgrading.
All that aforementioned, the GeForce RTX 3080 might work if you have a very cost-effective 650W power provide. We test whole organization power draw for our graphics lineup tests. In a system with a six-core Meat i7-8700K, two SSDs, 32GB of fast computer storage, a liquid Mainframe cooler, and RGB lights galore, the RTX 3080 Founders Edition maxed out at 482W of total system of rules power draw.

That's non a worst-case scenario though. We test exponent in a GPU-bound game at a GPU-bound 4K settlement to see what happens when the graphics card specifically is pushed to the max. For our games examination, we overclock the 8700K to 5GHz on all cores, which puts its performance on a par with the stock Core i9-10900K, per TechSpot's benchmarks. With that overclock applied, we sawing machine the system draw between 500W and 550W of total power in some games that run into the Mainframe intemperately overly, like GTA V and Total War: Ilion. Newer systems with more cores pushed subordinate an vulturous overclock could obviously draw more.
Basic number skills tell you that 550W is ease under 650W. Depending happening the rest of your setup, and how hot information technology is in your room, you could probably run the RTX 3080 happening a 650W power supply. Just PSUs take issue in how they hand over the wattage advertised on the box. Less efficient power supplies need to take up Thomas More energy from your wall socket to hit their rated maximums. An 80 Plus Bronze-rated force provide will commute at least 82 percent of your paries energy to PSU production, with the rest wasted equally heat. A pricey 80 Plus Pt PSU converts 89 to 92 percent of the power it draws from the wall to literal output into your computer, depending on the load.
Sol what? The less economical your PSU is, the less reliable it is, and the harder it has to do work to convert wall energy to factual power yield. A power supply that needs to work harder tends to offer less reliability and longevity than more efficient models. Being in a hot room give the sack also reduce your power cater's output.
Asus Asus has built a purpose into its ROG Strix RTX 30-series cards to sense if the PSU is unable to follow with loads. The Light-emitting diode lights will blink if on that point is a power sag.
That could be an issue with the increased mogul demands of the RTX 30-series. Don't hold our word for information technology–Asus said exactly that while viewing off its ROG Genus Strix RTX 3080, which includes sensors along its trio of 8-pin power connectors to testify you if they're getting the energy they need. From our reportage:
"The company aforesaid a progressive GPU can go from using nearly no mogul to of a sudden spiking to hundreds of watts. That's something a marginal PSU, or one that's been nonvoluntary hard, power not constitute busy, Asus said. 'And even if they own a high-energy PSU, if it has been run hard for a number of years, its voltage regulation may no more be up to cope with the fast load changes,' the ship's company added."
Your top executive supply isn't the only concern if you're purchasing a GeForce RTX 3080 with just two 8-pin power connectors, equivalent Nvidia's Founders Variant. The RTX 3080 is rated for 320W of total board mightiness. Each 8-immobilize power connexion can supply 150W of succus, leaving your motherboard's PCIe slot to pump out the rest. Now, PCIe slots are rated for 75W of power, but less-interlacing motherboards may struggle to do so, Asus warns.
"This approach is perfectly within specification, simply it may create additional baron-obstetrical delivery and thermal demands that some motherboards might not be built for," the company said—specially if you want to overclock your graphics card. Asus and many different third-party graphics card suppliers have assembled their higher-end RTX 3080 offerings with a trio of 8-pin ability connectors to facilitate the potential outlet.
Brad Chacos/IDG Those are a lot of words to get in reply where we started. Fare you need a bigger superpowe supply for RTX 3080? Definitely perhaps. I'd strongly recommend victimisation at least a 750W PSU like Nvidia recommends, especially if you're using a system that's full of budget or mainstream parts that have been ridden grueling the last few eld.
I'll close this with an anecdote. My individual system packs an 80 Plus Platinum-rated 650W EVGA Supernova P2 power provide and a high-end Gigabyte Aorus X370 motherboard. I threw the GeForce RTX 3080 FE in it to see what would happen, and IT worked just fine for a night of gambling at totally the major resolutions—but if I planned on exploitation IT long-term, I'd feel a lot more comfortable upgrading to a 750W unit like Nvidia recommends.
