kenable 8 Pin PCI Express PCIe Power Cable from Dual 4 Pin Molex LP4 Adapter

Product Information

So, at least for Ryzen 3000, I think you need to connect both CPU connectors to avoid Windows 10 freeze. SATA to 8-Pin PCI-E Adapter Cable – If your graphics card has an 8-pin connector but your power supply has neither 6-pin nor 8-pin connectors then you can use this SATA to 8-Pin converter cable to power your graphics card. This power adapter cable uses two SATA connectors for one 8-pin power connector. Sami Fathi (October 26, 2022). "Greg Joswiak: Apple Will Have to Comply With the EU and Switch iPhone to USB-C". MacRumors . Retrieved October 26, 2022. As always, there are exceptions. The most power-hungry graphics cards come with a 6-pin and an 8-pin connector. For example, NVIDIA’s GeForce RTX 3060 has both types of connectors. As a result, it has a maximum power consumption of 170 watts.

I’ve bought a Ryzen 3700X (65 watts TDP), a MSI X570-A PRO (with also both connectors) and a Seasonic FOCUS Plus Gold 550 as PSU.

NVIDIA eventually developed an efficient cable system, as it needed cables to draw more power externally for its GPUs. So, a power-hungry graphic solution came rather with a compact solution. You can have 2 x molex -> pci-e 8pin ... each molex has only one 12v wire, and each molex is rated for 5A of current, so in theory your adapter would be good for 2 wires x 5A x 12v = 120 watts.

The GPU power connector is commonly known as PCI express cables or PEG cables. The PCIe express cables are also termed to describe 6-pin connectors. However, the power supply connectors in the motherboard are known as PCIe connectors. Every computer/PSU has PCIe x2, 4, 8, and 16 slots. The graphics card that easily harnesses the power from a 6-pin connector is GTX 1060 and GTX 1650. These two graphics cards have a power requirement of 120 and 100 watts, respectively. In many cases, Graphics cards have two 6-pin connectors. Two six-pin connectors will offer 150 watts of power, and the PCIe x16 slot will offer another 75 watts. Thus, the total power they would get is 225 watts. What Is An 8-pin GPU Cable? I think on modern power supplies the 6 pin can do more than 75 watts. The spec was before 2007 for 6 pin = 75 watts as they only had 2 hot wires. The pci-e slots are powered by the only 2 (if my memory is correct) 12v wires in the 24 pin connector. So, assume around 200 watts can go into the motherboard through the 24 pin connector, which are then split between fan headers, rgb headers, and possibly 12v to 5v / 3.3v dc-dc converters on the motherboard that may power things like ram, m.2 connectors (m.2 has only 3.3v but because a m.2 SSD may go up to 3A when writing, some motherboards don't use the 3.3v from PSU but use a dc-dc converter to produce clean 3.3v from 12v)In such cases, the graphics card draws 75 watts of power from the PCIe x16 connector, and the additional 75 watts of power get extracted from the 6-pin connectors. One hundred fifty watts of power supply is precise and more than expected for several GPUs. But there are also graphic cards that draw 320 or 750 watts of power. These are usually high-end power-hungry GPUs that demand power for superfast data transmission. There you have it; a complete explanation of how the power supply (PSU) of your PC works to deliver power to your system components. PSUs today also support features such as overvoltage protection, over-temperature protection, short-circuit protection, and more. Every power supply has a different feature set, efficiency rating, and max wattage rating. Power supplies available in the market today cater to users of different budgets & wattage requirements. That said, let’s talk about some common PSU features, including the connector types, PSU types, and more. I am trying to understand how a 2x SATA (108w combined) can work with an 8-pin PCI (150w) connection without overloading the SATA connections, and perhaps damaging the motherboard or other components ? Also, I cannot find any information on how the S12 is wired in terms of which cables come off which rail (or maybe I’m completely misunderstanding how a dual rail PSU works?)

As the name implies, your PC’s power supply unit (PSU) is responsible for providing electricity to the various system components. Until the ATX standard of power supplies and motherboards came out in 1995, power supplies did not have a standardized design or form factor. As a result, there were many different kinds of power supplies with no universal design, like AT, Baby AT, and more. Intel patented the ATX standard for motherboards and power supplies in 1995. By 1999, the older Baby AT/AT power supplies became obsolete. Reviewers criticized Apple for continuing to include a Lightning port on its products instead of moving to USB-C, a more universal port, on its introduction, with this criticism escalating as Apple adopted USB-C as the primary connector for both data and power on the iPad Pro and MacBooks. [27] For the new one I found there seemed to only one way to fit the 6 pin PCI and the 2 pin into the new 8 pin. When I boot I get all sorts of beeps. I’ve verified that the card is well seated into the primary slot. Older power supplies did not have an Active PFC feature. They used to have a switch for the PSU’s input voltage, commonly set in either 110-115V or 220-230V mode.

Multi-rail power supplies are not by many anymore. Single-rail power supplies are widely used in consumer-grade PCs, including many high-end PCs too. Multi-rail PSUs are usually intended for workstations and servers today. and I don’t know if I understood correctly but this schema https://i.imgur.com/Dv9738Z.png (which you posted earlier in comments) says in general that 6pin and 8 pin are the same – both have 3 current wires, sense A and B can be ommited, and only difference is in one additional grounding pin).
