Question I possess a B450M R 2.0 as a fresh unit for a 5800XT — is this a significant issue?
I'm wondering if it's alright to attempt an update without another CPU, or would I be stuck in my current setup?
When checking the motherboard box, confirm if it supports 5 series readiness. If not, the BIOS must be updated.
There are several boards available that fit the b450m r2 specification. At least two main models are widely recognized as “B450M R2”:
ASRock B450M Pro4 R2.0 and ASRock B450M/ac R2.0. Both utilize the AMD B450 chipset, come from ASRock, and the R2.0 label refers to a revised version offering enhanced features or better compatibility. Other brands might offer similar boards, but these two are the most commonly discussed.
Are they suitable for 5000 series?
Yes, both motherboards support AMD Ryzen 5000 series CPUs. They officially back Ryzen 2000, 3000, 4000 G-Series, and 5000 processors, and often include the latest R2.0 BIOS updates that simplify installation. For optimal performance, ensure your board has the most recent BIOS, though most new R2.0 boards should work seamlessly with Ryzen 5000 series CPUs.
Are you prepared?
Assuming you've chosen a suitable power supply unit from the SPL's PSU tier list and also found compatible RAM on the manufacturer's support page under QVL/Memory support.
it was the ac r2.0, currently i have my cx650watts, and i intend to upgrade it soon. however, my main issue is with the bios—i'm uncertain if the bios from the b450m ac r2.0 would be recognized by the 5800xt natively.
It should work, though there are some uncertainties. It might be a version lacking strong ripple suppression, which wouldn't be suitable for your parts. I don't believe it matches the cx-m 2025 atx 3.1 with concerning notes. It could also be a Tier C model that isn't ideal—might pass but isn't recommended by forum experts. If it has the Green label, avoid using tier E. Frazzle dazzle.
In a precise sense, I wouldn't suggest anything because I'm not the one responsible for the product's warranty. Still, it's important to note that setting up a power supply is needed to run the computer. Depending on regional availability, tier B+ (often seen as borderline quality) is slightly more affordable, while tier A is better. Generally, Corsair RX or brands like Evga, Superflower, Seasonics are preferable. You should cross-check the PSU tier list with PCPP for the best price in your area. Be Quiets are another choice, but as long as it's either tier A or B+, it should be fine unless there are occasional defects covered by warranty.
Using a power supply that's nine years old isn't advised, especially with new parts. Their power requirements will be higher than the previous setup, which could lead to wear and tear on internal components. This might damage your brand new motherboard, CPU, RAM, GPU, and ultimately cause the whole system to fail from the start.
to be honest, i was considering using it but as you mentioned, right now it’s not the best idea. i’m hoping to find an evga with 650watts or a 750watts model. i don’t really like corsair, even if they’re rx, but the one i had was ten years old. the degradation in venezuela because of electricity issues is really taking its toll, so i’m probably not upgrading the new mobo, cpu, and ram just yet. hell, i’m really nervous since the psu is making noise now, and it might be because of those electric problems in venezuela that i’m 100% sure are slowly killing the psu.
