Just released Big Sur 11.1, can I update normal? as if it were an original Apple machine, or do I need to do something?
I am using OpenCore 0.6.4 with the updated kexts.

I just updated from System Preferences > Software Update... I'm on OpenCore 0.6.4.

P4, P5, P6, and P7 should be used for graphics cards or Thunderbolt card.

P2 and P3 should be used for motherboard to power CPU.

I have no idea why the keying of the connectors don't match the motherboard. I think it's best to contact Silverstone and/or Gigabyte.

Yes, already in progress. I‘ve done Silverstone and will do GIGABYTE shortly...

Interestingly some older, basic motherboards came with just the 4-pin plug. It's kind of auxilliary to the main ATX connector anyway, which started as 20-pin and grew 4 more of its own. The auxilliary seems to have grown more pins too so that it could accommodate more recent, power-hungry processors. Previously you could run a system with only the main ATX for power anyway. Things change. Evolution I suppose.

As an engineer (me too) you might find the Wikipedia article about ATX form-factor and power-supplies educational.

(Yes, it's a bit "dry").


My previous Z87N - WiFi had only the 2X2, so it didn’t need a 2X4 connector. And yes, I have read the Wikipedia page with the ATX, The micro-ATX and ITX variants. I was curious about the differences as the Z87N is a micro-ATX...

I am only using the 2x4 connector on the motherboard. My 2x2 is unused. My understanding was it was one or the other, but not both.

Both can be connected and used. However, the 8-pin EPS connector is more than sufficient under normal circumstances. The only time the additional 4-pin EPS connector is needed is for extreme overclockers who want to feed insane amounts of power to the CPU which, in turn, will require even more insane cooling.

The guys using liquid nitrogen trying to set overclocking records.

Yes. Exactly.

I've run my motherboard with and without the additional 4-pin EPS connector connected and everything was fine under both scenarios.

Good to know. With just the ATX_12V_2x4 connected, it seems to handle my OC i9-9900K with no issues(OC'd at 5.0GHZ)
