There's a lot of info to go around, but the short answer, as many have said already: You'll be fine as long as your power supply has the wattage your system+GPU needs. so i am wondering whether or not i can use an adapter that connects 2 6 pin connectors to an 8 pin connector for power a gpu like a rx 570 which takes 150 watts.

6-pin to 8-pin adapters safe? - Tech Talkies Are 6-pin to 8-pin adapters safe? - Tech Talkies

You should use a dual PCIe 6-pin to single 8-pin PCIe cable because a PCIe 6-pin power cable only delivers 75 watt, whereas a PCIe 8-pin power cable can deliver up to 150 watt, that is why you need two PCIe 6-pin power supply cables to "create" one PCIe 8-pin power supply connector: A GTX 1650 would likely be your best option. GTX 1060 3GB would be around the same performance, GTX 1060 6GB a bit more performance. Make sure you do it under supervision after studying everything about the setup. 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. However, as the launch of the 12-pin, NVIDIA GPU is recent, not many PSUs developed have 12-pin PCIe connectors. Most of the connectors that you can find in standard PSUs include dual 8-pin PCIe connectors or 16-pin PCIe connectors. So, NVIDIA brings you 8-pin PCIe to a 12-Pin PCIe converter cable. This adapter will offer you compatibility with all the latest GPUs. 5. SATA to 6-Pin PCI-E Adapter Cable

Nvidia Please No

This smooth running may be absent; instead, an explosion may occur. The critical problem is that you’ll be maxing out a cheap PSU that may cause dire consequences for upgrading. Are you concerned about whether using a 6-pin to 8-pin adapter is safe? This article seeks to answer the question and reduce your worry. As mentioned earlier, the 12-pin power connector is the latest technology necessary for NVIDIA’s 3000 series graphics cards. Because there were relatively few PSUs with a 12-pin power connector on the launch of the 3000 series, NVIDIA included a dual 8-pin to 12-pin adapter with its product. SATA to 6-Pin PCI-E Adapter Cable OK thanks, it worked fine with the double 6-pin to single 8-pin adaptor! 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...

6 pin to 8 pin vs single 6 pin to 8 pin [SOLVED] - Dual 6 pin to 8 pin vs single 6 pin to 8 pin

Several CPUs come with multiple numbers of PCIe x16 slots. This enables users to harness more GPUs to the system. However, it eventually increases the power consumption of the whole system. Connecting a 6 Pin PSU into an 8-pin GPU involves many risks, and it can include fire hazards as well. It is because; when you connect a 6-pin PSU into an 8-pin GPU, it will attempt to extract immense power, more than its cable rating. In such cases, it can lead to the burning of cable. Apart from that, it can also lead to deleting all your crucial data. General rule of thumb: if you have to use an adapter to make your PSU do it, your PSU shouldn't be doing it. The only exception to that, imo, is dual 6-pin to 8-pin, which is imo usually safe as long as the adapter isn't total shit. A single 6-pin to 8-pin will provide as much power as a 6-pin, and is generally a bad idea. In conclusion, these are the differences that you should know about 6-pin, 8-pin, and 12-pin connectors. You have also learned about some easy ways to achieve connections with your GPU, along with the differences. But along with that, you should also assume the consequences you can face for any connection. would be pretty difficult to find new though. used probably but i personally am advicing against buying used gpu's never know man

Bad Move, Microsoft...

But I suppose it begs the question, assuming my PSU is "standard", i.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? There are even some exceptional cases where the GPU will have two 8-pin connectors. By adding the numbers together, we get a total of 375 watts, which is an extreme amount. In addition, you still need to power the CPU ( another big energy consumer) and the rest of your PC’s components. It is common in traditional PSUs, and the modern-age PSUs employ PCIe connectors. If you have SATA connectors and want compatibility with your 6-pin GPU, you can use SATA to 6-Pin PCI-E Adapter Cable. This power adapter cable offers you compatibility with SATA connectors and draws more than 150 watts of power for your GPU. 6. SATA to 8-Pin PCI-E Adapter Cable SATA to 8-Pin PCI-E Adapter Cable The usual 12-pin cables with 18 AWG-rated wires can extract up to 500 watts of power, directly bypassing the motherboard. 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. These power cables in the same physical space can harness four times more power than 8-pin GPU cables. A 4-pin to 6-pin connector helps you achieve compatibility with your GPU. Besides, the 4-pin Molex power connectors are the most standard connector type accessible today, and they were for all PATA and hard drives. The pin connectors usually have 4 Molex pins inside the adapter or converter cable. This converter cable connects with a 6-pin GPU to harness the external power supply. 2. 4-Pin Molex To 8-Pin PCI-E Power Adapter Cable
