Im looking to build a complete matx system in july/august with a ryzen 3700x. I dont plan on over clocking the cpu, memory, or gpu.

I am really liking this asrock b450m seems to have everything i need, asrock says it supports ryzen 3000, and it will support my crucial 32gb 2x16 ddr 4 3200mhz kit.

I realize the x570 has pcie-4.0 but as this is merely a gaming rig, and 3.0 isnt saturated yet for gpus, for ssd's i dont think i would even notice 4.0, maybe one second faster boot time?

I do notice that the x570m which is obvious a high end board by asrock has 8 phase, realizing first that they need to support up to 16 core ryzen 3000 with o/c.

So im wondering since im only using the 8 core low tdp 3700 without o/c will 4 phase of this steel legend be fine, this is a newer board released this year, reviews are all good, what do you think.

Will the b450m steel legend run the 3700x just fine with 4 phase vrm, will i get the benefits of increased performance of the ryzen 3000 series on this older motherboard

or do i need to ante up for the more expensive x570s that are coming out or would that be a waste??

Thanks all for thoughts and comments!

3700x ryzen 8 core 65w non overclocked
b450m steel legend matx motherboard
corsair 32 gb 2x16 ddr4 3200
1tb nvme ssd
650 gold modular psu (seasonic focus)
2070 super or 5700xt
Matx case to be determined, possibly antec cube max (not yet released)
 
btw i hear buildzoid says b450 vrms are too low for ryzen 3000, not sure if its in general or all

Buildzoid's a real pain to watch...but so informative if you keep in mind his bias. He's an extreme overclocker and very interested in finding a motherboard with VRM that can overclock a CPU to it's limit. So he beats pretty hard on a VRM design he feels inadequate for that purpose.

But if you watch several of his vid's (that's the painful part...he's unscripted, unfocused, gets of on tangents and is repetitive) he's made it clear that most any B450 or X470 boards should handle most any Ryzen 3000 CPU if NOT being overclocked. The ones to clearly avoid are easy to spot...they lack any kind of heat sinking on the FET's.

Otherwise, those a bit sketch would handle 6 core parts well enough even for overclocking and light overclocking of 8 core parts. It's when you get to the 12 core and 16 core parts you do have to be selective about the board in order to overclock or get the processor to stay boosted for a long time if not overclocking.

You have to keep in mind that Ryzen 3K CPU's are all rated with 65w, 95w or 105w TDP's, and this is using AMD's much more realistic TDP rating. While TDP isn't a direct electrical consumption rating it's an indicator and these boards are most all capable of powering this if not overclocked.
