I am buying msi b450m mortar and r5 2600, and i dont intend to overclock it at all, will the motherboad handle it and have long life time ?
should i be worried about vrm components quality and its heatsinks ? or should i go cheaper?
It's handling my R7 1700 overclocked to 3.95Ghz which is the practical limit of my CPU. It's not the VRM, as it's still under 80C after an hour of Prime95 small FFT stress test, but above 3.95 the CPU needs way to much voltage for my comfort.
I wouldn't propose this board for extreme overclocking but this is one of the few mATX boards you can run overclocked 8 core CPU's 24/7 without putting a fan blowing on the VRM. So yes, it's very safe to say it will run a 6 core 2600 solid even overclocked.
But if you're certain you'd never venture into overclocking you could certainly go cheaper. Just look at and compare board features. For instance, one other thing the Mortar has is a second M.2 NVME slot. It's limited to PCIE x4 Gen 2 but even that is way faster than SATA SSD which is all you get with most any other board with a second M.2 slot.
