Cable Matters (2-Pack 6-Pin PCIe to 8-Pin PCIe Adapter Power Cable - 10cm

Product Information

However, if you’re constructing a gaming setup with an RTX 3080/3090 or desire to prepare for the future (which is nearly impossible), you should select a stronger PSU. back then with that HD 3870 X2, I can't even understand how that old HEC 300W ran it without problems.

The lack of a handful of pins creates a load on the motherboard, forcing the entire circuit to break down. NVIDIA eventually developed an efficient cable system, as it needed cables to draw more power externally for its GPUs. As 150 watts will be enough for most mid-range cards, these usually feature the 6-pin power connector.Have been using this cable now for over 2 years and besides the bottlenecking that the CPU is doing, the GPU has performed very well. If you have an existing GPU, you need to unplug the connectors and take them out by unscrewing them. It would allow me to connect the GPU to PSU but only supply 75w +75w instead of the 150w +75w this GPU seems to require otherwise I should just get a reference RX480 or GTX 1060 both of which I am loath to do. mini eLiXiVy: my open source 65% mechanical PCB, a build log, PCB anatomy and discussing open source licenses: https://linustechtips. Some supplies, particularly cheap ones won't be safe supplying 150w through that single rail with an adapter on it.

So, by assumption using your logic, divided by half I am getting 22A and 210 watts on each 6 pin which will then pass through the 8 pin. However, as the launch of the 12-pin, NVIDIA GPU is recent, not many PSUs developed have 12-pin PCIe connectors.Connecting a 6 Pin PSU into an 8-pin GPU involves many risks, and it can include fire hazards as well. A 12-pin connector is roughly the same size as an 8-pin connector, but it can draw a lot more power.

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. The 8 pin spec has been available since 2008 - so access to 8 pin connectors doesn't really come into it. e. not a massive 1200w gaming jobby with 45A on each line but a "normal" PSU, why would AIB manufacturers need to move to an 8 pin connector with two more neutrals?You have also learned about some easy ways to achieve connections with your GPU, along with the differences. The 6 pin physical connector and cabling (18 gauge wire), can in theory cope with around 190W - but this assumes that the cabling of the PSU actually meets that spec (i. e. cheaper unbranded PSUs frequently skimp and use cheaper narrower gauge cabling), and also assumes a set temperature. In addition, you still need to power the CPU ( another big energy consumer) and the rest of your PC’s components.

You can find power connectors that are not compatible with the motherboard or other hardware in the computer. If your slots are not compatible with the GPU connectors, you can use an adapter to get compatibility. Overclockers UK sell a variety of coloured and braided cable extensions including Bitfenix braided cable extensions and Cable mod's PSU replacement cables. I couldn't find if they were connected to different rails but I took 6-pin cables number 1 and 3 so I guess they must.The new-age graphics card consumes much power and demands a higher supply from direct external sources. There is a chance that SATA won’t be able to handle the power that your graphics card requires, and this is not something that you want to encounter, especially if the cable is labeled as “ SATA only“. First of all, turn your PSU off while plugging in, then remove the PSU panel and unscrew the older GPU, and take out the cable integrated into the PCIe slot. A top-of-the-line graphics card can place too great a burden on many PSUs, and that is something gamers need to avoid. In several cases, you can also find manufacturers offering you premium 12-pin GPU cables with 16 AWG standards and the efficiency of drawing up to 600 watts of power.
