no you cannot sli those two cards...the gt 520 does not support sli so regardless of motherboard and power supply you will NOT be able to sli those two cards edit....if you are looking to put both cards into your system to have multiple monitors yes they would work you would just have to make sure that your motherboard has two pcie slots available

If you mean as SLI pair to enhance performance for gaming? No. It does not even have the SLI bridge ports as far as I can see.

And even if they do, it is not worth it because the GT 520 are very weak anyway. You can easily find a graphics card costing less than the 2xGT520 that will beat the SLI in terms of performance.
