I have an RX 580 8GB (Powercolor Red Devil Edition), but my PSU only has a 6 pin. (2024)

FAQs

How many pins does RX580 need? ›

The graphics card is connected with a 6-pin connector to an 8-pin input.

The AMD RX580 draws a max of around 185W stock - a quality 480W power supply should be sufficient assuming a similar mid-range CPU and rest of system.

No you can't. The GPU has 8 pins and will expect an 8 pin plug. You can, however, use an adapter like the one shown below to turn your 6 pin power into 8 pin power. If you do this, be aware that you are sucking more power from that 6 pin rail than it is necessarily designed to support.

Any genuine 600W PSU from the past 15 years should have atleast 2x 6-pin PCI-e connectors, a modern one should have 2x 8-pin connectors. The RX5700XT is a fairly high end card. By using a bad PSU you can cause some serious damage to your PC.

A RX 580 uses a 8 Pin Molex connector because I own one too, RX 580. Also keep in mind to have checked the market for power supply before you go for such a beast. There is also an option where you can use 6 Pin to 8 Pin Molex connectors available at local markets.

No, you want to use an 8 Pin. The safest thing to do is to get a new power supply that is rated for your computers total wattage power draw (+10% to 20% over). IF your power supply is sufficient to deal with the power draw you can buy a Molex to PCIe adapter, but I wouldn't recommend it.

Should work fine. The RX 580 isn't that "power hungry" tho, you can always undervolt it a bit but with a 450W PSU you should be fine.

What undervolt wattage should I set for my RX 580 GPU for a 400W PSU? Sapphire recommends a minimum PSU of 500 Watts for your GPU card which means your PSU is about 100 watts weaker than it should be. I suggest you just upgrade your PSU to a metal rated PSU to at least 850 Watts.

The RX 580 will need, at top gaming performance, 160–180W.

Is it OK to use a 6-pin to 8-pin power adapter? There are 2 types of 6-pin to 8-pin power adapters. One type converts from two 6-pin plugs to a single 8-pin plug. These adapters could damage your computer and should not be used under any circ*mstances.

Do you need both 6 and 8 pin for GPU? ›

A 6-pin connector can safely provide only 75W of power. In a case that the GPU will require more power, it will expect to get up to 150W of power through the 8-pin connector. This will result in the 6-pin connector and wire to be overloaded and will start to heat up and eventually the fire will start.

A *good* GPU with an 8+6 design shouldn't start up unless both connectors are present. If it needs 300watts and tries to draw that through the motherboard and the 8pin connector (which should max out at 225watts) then you've got a deficit of 75watts. If you're lucky the program will crash due.

No, you should not directly plug a 6-pin PCIe power cable into an 8-pin GPU power connector. Here's why: Physical incompatibility: The 8-pin connector has two additional pins compared to the 6-pin connector.

6-pin power connector can provide up to 75 watts.

A PCIe slot can provide up to 75watts. The 6pin connector can provide up to 75watts. The 8pin connector can provide up to 150watts. If your GPU can 8+6 then it could, by design, draw up to 300watts.

The card needs an 8-pin power connector But if your power supply doesn't have an 8-pin (or 6+2 pin) connector, you can use an adapter to combine TWO 6-pin connectors from the power supply into a single 8-pin connector for the graphics card.

System Requirements:

500W (or greater) power supply with one 75W 8-pin PCI Express power connector recommended**. Minimum 4GB of system memory 8GB (or more) system memory recommended for AMD CrossFire™ technology. Installation software requires CD-ROM drive, keyboard, mouse, and display.

There are two DisplayPort 1.4 outputs and two HDMI 2.0b outputs as well as a dual link DVI-D output. Combined with AMD's Eyefinity, the GPU can provide an immersive gaming experience using up to four monitors.

The general rule is that your GPU and PSU power connector types should match exactly, meaning that a 6-pin GPU power connector should connect to a 6-pin PSU power connector, an 8-pin GPU power connector should connect to an 8-pin PSU power connector, and so on.
