the first one burnt out after a month, it was taken to an after-sales service and reassembled by LDLC. It smoked again 6 months later! another after-sales service and I'm waiting for the rest!
Don't buy this model!
Efficient motherboard for a modern, functional configuration for a PC in gaming mode
This brand is rarely bought, yet it's an excellent quality motherboard. Its design is simply magnificent, and its use on my gaming PC is perfect, coupled with a Ryzen 5 5600X, it's pure pleasure.
Arrived on time, compliant, smooth, satisfied with the product and service?
I have to find a fault as there are some characters missing, the boot is quite slow on this motherboard.
