We normally pack the motherboard with strong brown folder box. 2. The motherboard needs powerful power supply. Suggest to use 500W brand power supply. 3. Some motherboards may have little scratches or thermal paste or finger print on the metal bracket or other metal parts, this is normal, they could be caused in assembly at workshop or during testing. It does not mean they are refurbished, all RA store motherboards are full new as we stated. 4. The M.2 port close to CPU supports NVME/PCI-E SSD and the below one supports NGFF/SATA SSD. 5. On the basis of not bringing function changes to the motherboard, the factory would probably improve the motherboard external design, which would probably lead to some appearance difference between batches, please refer to the real-life object. 6. If a processor is included in your order, we will keep the processor in the processor socket after testing, and the thermal paste is also covered on the processor, so when you get your products, you can directly fix a CPU cooler on the processor and test the motherboard. 7. The dual motherboard doesn't support CPUs like E5-16XX (V1, V2, V3). 8. It's better to use same model/same cores processors in the dual board. 9. If you use i7 series processors, pls do check advance if they can support REG ECC ram, since some models are incompatible with them. 10. If you have any questions after receiving the product, we sincerely hope you can contact us to check first. Order now and experience the ultimate performance of dual CPUs!
