Hi there

 

Should I ignore this or have to pick a different power supply.

 

Specs are in the message,

I was building my PC on PCpartpicker just to let you guys know.

 

Thanks

i had to figure this out recently. you only need 8 pin for eps, 8+4 is only needed in extreme cases. from what i was told, even a 3900x really wont need it. I'm running 8 pin eps on my x570 tuf gaming atm with a 3700x, no issues.

Extra 4-8 pins are for PCIe power. You may or may not need that depending on if your graphics card is powered off of PCIe. Generally speaking, though, if there's extra pins, there's a reason for them, and you should plug power into all of them. You'll just have to see what it does with your particular build I guess.

extras power for PCIE comes in PCIE 6 or 8 pins. the extra CPU power connectors are for OC high end CPUs that suck power 3900x and 3950x can needed them for high OCs

Keyword being "extra", yes extra power to the card comes from it's on power cable, but it also draws power from the PCIe lane. 8 pin on lower boards is enough to power CPU and PCIe lanes, the extra 4-8 is for PCIe when the full 8 pins are going to the CPU for overclocking or just beefier CPU.

CPU 4 or 8 pins don't give power to the PCIE lanes. that is why some WS or high end boards designed with lots of GPUs in mind will have an extra 6 or 8 pin above the PCIE slots to feed extra power.

Do you have any examples of literally any board that powers the PCIe slots through the CPU power cable, rather than the two 12V pins on the 24 pin?

The eps connector isn't even close to the pcie slot

It has nothing to do with it.

Your GPU has nothing to do with it don't worry about that 

A single 8 pin eps can provide up to 384w of power 

Which you won't reach with any ryzen chip.

So I have to change power supply?

Perhaps, but it would not be because of that connector, really, you wont need it. You gpu will have its own cables for power, and unless you overclock using nitrogen you likely never need that extra connector.

 

As a tip, post your parts list in "new builds and planning" section, state your budget and goals/games/programs, and lots of helpfull people will assist you in making sure it all works out :)

I've run into this as well. First build, and my PSU only has a 4+4 connector, but the mother board has both an 8 pin and a 4 pin connector. I know I can purchase a molex to 4 pin ATX (StarTech of course) and my PSU has a single 12v rail, but is there some magic going on behind the scenes on higher-end/priced PSUs that is not happening on the molex connectors?

No.

 

Using such an adapter is dumb.

 

Just use the 4+4 and call it a day.
