Can I power a 3080 with one cable?

Single power plug with a 3080 would not be recommended as it can cause power issues for the card, having two separate plugs is ideal.

Does the 3080 need all 3 power cables?

As it turns out, some of the new 30-Series GPUs require two of the PCIe 8-pin connections (otherwise known as “6+2” connectors), while others require three – and even within the 3080 product line specifically, the power connection needs vary depending on the specific card.

Can one PCIe cable power a 3080?

The principle behind using a single PCIe cable for a graphics card still applies for models requiring more than two connectors, like the EVGA RTX 3080 FTW3 Ultra. Check your PSU to see if separate cables are recommended; if not, just make sure you're not surpassing how much power a single cable can provide.

Can I use one cable for 3080?

Theoretically yes, but it would be pushing this power supply. First, you want a 3rd party 3080 that is not using the 12 pin power connector. Those should have two eight pin PCIe power connectors. Your 6+2 pin cable should work there.

Do you need 2 separate power cables for GPU?

Thus, to power high consumption graphics cards (above 225W) with two or three PCIe slots, SilverStone recommends using two or three separate PCIe cables to connect such cards to the power supply.

Why you should STOP using these...

Does the 3080 need two power cables?

Single power plug with a 3080 would not be recommended as it can cause power issues for the card, having two separate plugs is ideal.

Can you run GPU on one cable?

Yes, you can use both 6+2-pin or 8-pin connectors that are on the same cable (daisy-chained connectors) for most of the lower to medium power draw GPUs. But do not use daisy-chained connectors on power hungry GPUs. For 3090 rated at 350W you should use 3 individual PCIe cables if it has 3 connectors.

Does 3080 need all 12 pins?

The 3080 also uses the 12-pin, and includes the adapter. It requires 2 different 8-pin connections to the PSU because it draws more power than any single cord can supply.

What does a 3080 require for power supply?

While NVIDIA recommends a 750W PSU for the RTX 3080, it tested a system with a 10th Gen Intel Core i9-10900K processor (CPU). That's a rather hefty CPU with a TDP of 125W, so depending on your personal system setup, you might be able to get away with something like 650W, especially if the PSU is new.

Do I need 3 cables for GPU?

How Many Power Cables Does My GPU Need? That depends on your particular model. It, at the very least, needs a single 6-pin power connector. If it's a mid-range GPU, then it'll feature either dual 6-pin connectors or, alternatively, a single 8-pin one.

Should I use two separate PCIe cables 3080?

Yeah, just as SavageNeo said. Use two cables just to be safe.

Does the 3080 need 3 PCIe slots?

No. You do not need 3 PCIe cables for a 3080 Ti. The 3080 Ti only requires one 8-pin PCIe power cable in order to provide the necessary power for the card. Depending on your specific PSU, you may or may not need an additional 6+2-pin PCIe power cable.

Does PCIe 4 matter for 3080?

We wanted to see if that carried over to PCIe Gen4 with the RTX 3080. The data certainly suggests some benefit for PCIe 4.0, but not a lot. At 1080p, PCIe 4.0 offers a 4% performance improvement over PCIe 3.0 when both tested on AMD's X570 platform.

What is the minimum power limit for 3080?

Power should go up to 370W but caps at around 340W in GPU-Z and HWInfo, average ~320W during OCCT stress test.

Is it safe to daisy chain PCIe cables?

Yes, but on most motherboards doing so will result in a loss of GPU performance. This is because on most motherboards, only the top PCIe x16 slot is connected directly to the CPU.

Can a 3080 run off 750W?

Will RTX 3080 work with a power supply lower than 750W? Yeah , Nvidia itself recommends 750W PSU. As flagship i9-10th gen demands 125W and the new RTX 3080 demands insane 320W. Anyways buying this 750W PSU will be beneficial and somewhat future proofing.

How many PSU cables does a 3080 need?

3080 with 3 pci-e on 2 psu cables.

Does the 3080 use a lot of power?

It's not the most power-hungry graphics card we've ever tested, but the MSI 3080 12GB Suprim X can draw quite a bit of power. It averaged 384W in both FurMark and Metro Exodus, about 25W more than the 3080 Ti and 3090 Founders Edition cards, and over 50W more than the 3080 10GB.

Is 1000w PSU overkill for 3080?

Yes, it's enough, but it might not be ideal. An RTX 3080 uses up to around 370W under peak load, and a Ryzen 9 5900X uses up to around 150W under peak load.

Can I use a 6 2 pin for 3080?

No, that will not work, you have to have all THREE 8-pin headers populated for the card to even work. The card will not even power on if you only plug in two out of the three connections.

Can I use two 6 pin in 12 pin?

You cannot plug 2 6 pin cables into the Nvidia 12 pin adapter because the 12 pin is physically smaller.

How many pins for 3080 12gb?

Being a dual-slot card, the NVIDIA GeForce RTX 3080 12 GB draws power from 1x 12-pin power connector, with power draw rated at 350 W maximum.

Is it safe to power 2 8-pin connectors on a GPU with just 1 cable?

Yes. That's what PCIe power cables are for. They deliver 12V power to PCIe graphics cards. Some graphics cards have a 6-pin PCIe power connector, some have an 8-pin, and some have multiple connectors, sometimes a combination of the two.

Is it OK to pigtail a GPU?

Unless the manual for your graphics card says otherwise, it's almost always acceptable to use a split or pigtail power supply cable for two of the three-pins in the graphics card.

Can you run GPU without all power cables?

Your graphics card will not run unless you connect it to a PSU. Most gaming-grade graphics cards require additional power connectors. ... Your graphics card will not work correctly without the correct power supply. In fact, if you do not connect those PCI-E power cables, your PC may not boot.
