This is a genuine Dell Precision 390 Motherboard. We have done more than just test this motherboard. Here at Discount Electronics we go one step further and replace any components that have potential to fail in the near future.

Sometimes motherboards have 'known bad components' such as capacitors that may bulge or leak. The presence of these may not cause failure today but will in the future. That is where the experience of our techs comes into play. They know what components to be on the lookout for and they replace them.

The result is that the Dell Precision 390 Motherboard you buy from is better than the motherboard you can get anywhere else. It may even last longer than the original.Our Precision 390 Motherboards are truly refurbished and come with a warranty.

There is a reason we have been on the Inc 5000 list of fastest growing companies 6 years in a row and voted Best Computer Store in Austin year after year. Service after the sale.

We are just a phone call or email away should you need help.

    Excellent all around, great packaging. 30 minutes to swap out motherboards and we are up and running again.

    Worked super, got our system back up & running! Got a spare MB, just in case the capacitors let go on another Dell MB on the other 3 systems.
