Daisy chain cable gpu.

Daisy chain cable gpu and 2 ports basically running off the same cable aka the daisy chain. Dec 4, 2020 · Daisy chaining fans and SATA power is fine, the power draw, etc is not even close to what we're talking about with GPUs. Transient spikes will just lead to an underpowered GPU. Power is also enough, your CPU is not power-hungry (+-130W PEAK consumption CPU +-270-300 PEAK consumption GPU, summary is 430+ 25-50 watts for RGB/coolers etc. I ran a bench Mark with the daisy chain, and a bench mark running two separate cables with the same scores. Before u can get away with chain. If that is what I have to do then I will add the 3rd cable, it's just such a massive pain to add the 3rd pcie cable to the PSU in the current case and the 3090 has been fine using 2 pcie cables with 3 connectors, 1 being a daisy chain. To elaborate it further, each individual cable is rated for a certain current (i. A 480W spike is 40A at 12V, which would result in a voltage drop of approximately 0. It really just comes down to cable quality, I was a tad concerned on my SF750 but it appears that the 6+2 daisy chain is 16 AWG so happy days.

Given there are 3 slots, one of the cables will use the second daisy chained connector and the other cable will just use 1. (Of course a tad difference as you won’t get identical scores even running the test twice) Which then concludes running a daisy chain isn’t limiting the power draw which then isn’t limiting performance. This means you draw 300w over a single 8 pin cable which is rated for max 150w. TLDR: If you have a one rail 12V Good quality PSU with a good PCIE cable, you can safely daisy chain / piggy tail your graphics card, taking into account that one PCIE cable of 18agw can safely pull arround 288w through it (do your maths with your GPU max watts consumption). Jan 4, 2025 · But if let's say we assume that each cable can handle 300W, does that mean my GPU would get: - 300W (150W x 2 from the daisy-chained cable), - 150W (from a single connector on the second cable), and - 75W (from the PCIe slot), for a total of 525W? Or I could only get 150W in total from the daisy chained cable regardless? Your PSU has 2x6+2 pin, see no problem. For power, I used one of those PCIe cables that has multiple connectors (daisy chain cable) but I'm NOT using it to daisy chain the graphics cards - I couldn't if I wanted to, the card only has one 8-pin connection slot.

Graphics Card Limitations: Verify that your graphics card can support the number of monitors you are connecting. That cult of "daisy chain is bad" is hilarious. The third connector on the graphics card has been implemented in order to stop people from daisy chaining via a single cable, so they would at least connect two separate cables, which ultimately reduces the risk of PSU shutdowns due to voltage spikes on the 12V lane. Even if a daisy chain GPU power cable does *work* it might be less than optimal and cost you performance. I see there is a lot of debate about whether it is safe to use 2 8-pin cables to occupy the 3 slots (utilising the pigtail/daisy chain of one of the cables), and I am not really sure what to That is what I was planning to do.
