4 Pin CPU Power

Hey guys,

So i'm planning out a tiny (Mac Mini) sized pc build with an i3 8100 and no gpu. Mostly doing to be used for surfing the web and word processing and such. The case I want to use come with a tiny 150W PSU that I need to power the system. My only concern is that the PSU only has a 4 pin cpu power plug and every motherboard im considering has an 8 pin power socket. Can I get away with just plugging the 4 pin into the 8 pin slot? I tried reading the manual for the msi b360i, which is a board i am considering, but there is no mention about the information i'm looking for.

 

Thank you in advance!

It should work with only the 4-pin.

Most (if not all) motherboards will POST with only a 4-pin and the ATX 24-pin plugged in, and operating it this way with a stock i3 8100 should be perfectly safe so long as the PSU is a quality unit.

I'd get a Ryzen 2200G or 2400G.

Because way better graphics and similar CPU Performance.

What case?

What PSU?


4pin is fine for lower end CPUs.

Would I need a 4 pin to 8 pin adapter or will it post with just a 4 pin connected to the board?

It will just POST with a 4-pin connected. It will fit in one half of the board's connector.
