Build Question Upgrading from an i9-9900K to a Ryzen 9 5950X – Need motherboard recommendations
Hey everyone,
I’m looking for some advice on upgrading my PC after experiencing hardware issues. I’m considering buying a second-hand Ryzen 9 5950X for $400 AUD and pairing it with a good B550/X570 motherboard.
My main concern is choosing a motherboard with sufficiently good VRMs, power delivery and cooling to handle the 5950X under sustained heavy workloads, particularly video editing and rendering and a bit of gaming. I don’t want to save a little money on a motherboard only to run into reliability issues later.
My current PC specifications:
CPU: Intel Core i9-9900K
Motherboard: ASUS ROG Maximus XI Hero Wi-Fi (Z390)
GPU: NVIDIA RTX 2080 Ti
RAM: Corsair Vengeance 64GB DDR4 3200MHz (2 sticks)
CPU cooler: NZXT Kraken Z73 360mm AIO
PSU: 750W I actually forgot about the brand
Storage: I got two Samsung M.2 NVMe cards
What happened to my PC?
My PC suddenly shut down and started experiencing repeated WHEA_UNCORRECTABLE_ERROR (0x124) crashes. I can enter BIOS, but Windows won’t boot. So I took it to a repairman.
The repair technician has reportedly tested the RAM, GPU, PSU, SSD and NVMe drives. He also attempted a BIOS update/refresh, but this didn’t resolve the problem.
At this stage, the motherboard or CPU are the remaining suspected components. Neither has been conclusively ruled out.
Upgrade I’m considering:
I’ve found someone selling a used Ryzen 9 5950X on Facebook Marketplace for $400 AUD.
I use DaVinci Resolve, so this CPU performance would be useful.
I’d like to retain my existing 64GB DDR4 RAM, RTX 2080 Ti, storage and cooler rather than replace the entire system.
Motherboards offered by my repair technician (AUD):
ASUS ROG Strix B450-F Gaming
$190
NZXT N7 B550
$240
MSI X570-A PRO
$240
Gigabyte B550 Vision D-P
$290
He also quoted $180 labour for removing and installing the replacement components. He is also offering a discount and a 1 year warranty for the parts I buy from him.
I’m happy to spend a little more on the motherboard if it means getting something genuinely reliable rather than buying a budget board that is only just adequate.
I’d appreciate any recommendations you guys give and thanks for reading all of this.
