Mining 1.0 time: slot more is ok. Mining 1.0, we use the extension cord is pin to pin, what function is no extension, anyway the mainboard of PCI - E slot stretching out, make a motherboard can be connected to 6 pieces of graphics. In this day and age, everyone is still have no idea of "mining board", we only know that dig depend mainly on the graphics card, the more the number of CARDS, the higher the efficiency of the mining, so this time we demand for mining the mainboard is very low: PCI - E slot is enough. Mining 2.0 era: solve the power supply problem Mining 2.0 era, everyone began to find, just ordinary extension cord is not enough, the graphics card may appear the problem of insufficient power supply, then began to someone on the extension cord join pin 4 D power supply, to increase the power of the graphics card. Good idea.At this time, the mining main board began to make a special "mining motherboard" name, and added 1 or more D power supply to solve the power supply problem. Mining 3.0 era: solving security problems In the time of mining 3.0, it was found that the power supply to the graphics card was not always ideal directly with D, the damage of the hardware was constant, and the extension of the third generation was born.This generation extension cord has a large number of PCB, after the power supply access has a complete filter and stable voltage, security, stability greatly improved.To this generation, the mainboard has no D power supply doesn't matter, and in order to further enhance the power supply stability, dig the mainboard start around PCI - E slot into voltage large capacitance, three generations of the extension of the motherboard collocation, effect over the previous solution.

AWG: Cables Everywhere! You should be able to access decent cables that provide good connections between graphics CARDS and PSU.But what is the optimal cabling? Problems like this can only be fun for those who use graphics CARDS to consume more than 200W.It also reminds us of the normal dual-8 pin connector for Radeon r9295x2.But is it really so strict that it's dangerous? What About AWG? AWG became a more common term in the PC world with the introduction of AMD`s Radeon R9 295X2. But what does it actually mean? In 1857, James Buchanan succeeded Franklin Pierce as president of the United States, Elisha Otis' first elevator was installed and the AWG standard was created. AWG stands for American Wire Gauge. It's a coding scheme for wire diameter, only used in North America, very inflexible and hasn`t been updated in ages. But AWG remains a quasi-standard, and there`s really no way around it when it comes to this kind of cable. If you enjoy calculating everything for yourself, the following table includes the AWG norms applicable to our PSU discussion. AWG Diameter (Ø) in mm Cross Section in mm2 Equivalent mm² (Metric) 16 1.29 1.305 1.5 18 1.02 0.79 0.75 20 0.81 0.51 0.5 Does AWG 20 Even Make Sense? Let`s start with the thinnest wires. At a room temperature of 25 degrees Celsius, at an average cable length of 55cm and assuming that the cable won't exceed a temperature of 50 degrees Celsius, even the thinnest AWG 20 cables still carry up to approximately 10A per wire. Three supply lines add up to a respectable 360W, which would be sufficient for an eight-pin connector. As usual, the devil`s in the details. In this case, the cable temperature is way too high. That`s why an AWG 20 cable should only be considered for PCIe power connectors of up to approximately 150W. A single six-pin or eight-pin graphics card power cable would be perfectly fine. AWG 18: One Size Fits All Theoretically, AWG 18 should be sufficient for anything between the PSU and graphics card, which is why this size is the most common. A single AWG 18 cable with two eight-pin connectors from a respected PSU vendor driving AMD's Radeon R9 295X2 yielded good results in our trial. It`s important to pay close attention to the construction of your PSU though, since there can be massive differences between manufacturers and their models. Unfortunately, we've found unserviceable solutions, as you'll soon see. Some makers of cheap PSUs even try to trick their customers with exceptionally thick insulation, resulting in the cable only looking like it has thick wires. AWG 16: One Cable To Rule Them All Very few PSUs offer AWG 16, since it's so much more expensive. Using AWG 16 cables is not really necessary, even if they do help to reduce cable temperatures in high-end systems, improving efficiency. AWG 16 is only worth the extra investment if high currents are going to flow through the cables. Of course, those who place big value on aesthetics and would rather forgo the second cable are on the safe side with AWG 16. What Could Go Wrong? Let`s take a look at a cable with two eight-pin leads, which should be able to carry 300W (2 x 150W), according to the ATX specification. The additional ground wires come right out of the connector, and the second connector is more of an extension cord than anything else, which means that it doesn`t have its own wires. Consequently, this cable consists of just three 12V wires and the ground. At least in theory, the wires do have enough diameter to serve their purpose. But, practically speaking, the pairs of wires twisted together in their connectors are a huge source of potential problems. Looking at the interface to the PSU itself is even more interesting. Everything terminates at a single six-pin connector. Even though the power supply's specifications state that this connector is rated at 20A (240W), and the PSU does shut off, just as it should, beyond that number, a pair of eight-pin connectors on the other end suggest 300W. Simply, this isn't possible due to the multi-rail PSU`s OCP, making the cable configuration all bark and no bite. Unfortunately, the kind of problems shown here reappear in many variations with other PSUs and their cables. Good Solutions And Better Solutions Normally, such a combined cable should at least have a solid eight-pin connector on the PSU.Here's a good example.The manufacturer decided to use the all-black cable for aesthetic research.It doesn't matter to you or me, but manufacturers have a higher failure rate because the cables are difficult to distinguish and identify. Ideally, each PCIe power connector has a single cable.This eliminates all the problems caused by high current and fast load fluctuations.The AWG 16 cable has a pair of 8 pin connectors, at least the eight-pole PSU connector is the highest available in the same category. So What If The Cable Gets Warm After All? This means that manufacturers have some problems with the purity of copper (and your safety).Most of these cables come from recycled materials, and that alone is not a bad thing.However, the PSU manufacturer's internal tests indicate that the use of alloys containing aluminium, magnesium or zinc is a common method of driving down prices. This line will be vulnerable in this way, which makes the cable less flexible.In this case, the usual security stockpile of AWG 20 is not enough, and the whole thing becomes a gamble. Just Don`t Use Them Ever Again: Adapter Problems Graphics card manufacturers keep adapters for convenience, but they should not be used again.They are outdated in terms of GPU promotion and PowerTune technology.Moreover, good psu is available without destroying Banks. At the same time, if their products cannot handle the load, PSU manufacturers do not include a second or third type of PCIe power cord.The missing connector is usually a weak warning signal, even if the label shows an excellent wattage level. The dual adapter is just garbage because all the roads will eventually return to the same 12V source.A PSU should not be pushed to provide what it doesn't have.The only exception is the psu from the OEM system, some of which may have sufficient capacity, but no matter which large store assembly system, the corners are cut off.However, these need to be thoroughly studied before use.
