Shocks or exploding are low percentage, unlikely type scenarios, even for the worst of power supplies. Obviously it's something that CAN happen, especially with a really terrible unit, but the far MORE likely problem is simply damage from overcurrent or overpower on a unit that doesn't have adequate protections or even much more likely, damage to graphics card or motherboard capacitors from high levels of ripple.
The Delta is underpowered and shouldn't even be considered for use with that graphics card. The Seasonic, is not one of Seasonic's better offerings and is really only a 432w unit on the 12v rails, which again is not sufficient.
You need to find something a lot more reliable and it should be a unit that is somewhere in the neighborhood of 550-650w.
You can use the guide below to help select a unit.
