Is it just me or do these motherboards actually have the same VRM? They both have 10 caps, 7 chokes with only difference being the heat sink on the MOSFETs. There's a price difference of $25 between the two; with A320 being the cheaper option and I was wondering if it's even worth getting the B450? 

 

Sure, the B450 chipset has more lanes, two more DIMMs and an M2 expansion slot which the A320 lacks but all I'm going to plug inside the machine is a weak PCIe 3.0 x16 GPU (HD 7790) along with an R5 1400 and 2 x 4GB RAM and won't be using the M2 slot, at least for the time being, as I already have a 2.5" SSD which is plenty fast for me.

 

Needless to say; I'm leaning towards the cheaper A320 but is there anything else I should be aware of before making the decision?

 

Thanks!

 

P.S Noob question but; do more chokes = better VRM? I was initially considering the Asus A320M and B450M boards (I love Asus, don't judge me!) but they have 1 less choke than these Gigabyte boards hence I'm considering these instead! So do the number of chokes actually matter or am I just being silly?!

 

Again... thanks!

B450 will be given support for 4th gen Ryzen CPUs, as confirmed by AMD, and has support for overclocking, unlike A320. Also, that heat sink makes a pretty massive difference for sustaining boost clocks during gaming.

I WILL find your ITX build thread, and I WILL recommend the SIlverstone Sugo SG13B

you cant do any CPU overclocking with A320, so yes. Probably not this B450 if I'm buying one for myself

Only if components in the same phase as the choke are the same. In this case the extra phase goes to the iGPU of Ryzen APUs, which isnt useful.
