Hello, will this riser be sufficient for 280x saphire toxic card?

It has only 2/4 pins, will it be enough? and why?
Also, what is that white marshmallow near to x16 PCI-E slot?
Thank You in advance

Yes, but you may not need the white marshmallow (capacitor) if you motherboard does not need a short between the pins A1 B17.
what do You mean by "does not need a short between the pins A1 B17."
You mean if the slot is x1 and not higher?
Some motherboards require pins A1 and B17 to be connected together with a wire to tell the driver the slot is occupied. A 1x PCIe card does this as standard but 16x PCIe cards have a different signal mechanism to tell the driver that a slot is occupied. Adding a 1x to 16x riser cable and 16x card may not tell the driver that the slot is occupied without pins being connected together. The capacitor makes sure that the correct signal is sent to the driver.
Awesome! Thank You kindly.
Could You also explain me why it has only 2/4 pins? will it be enough? and why? (on MOLEX)

There are 4 pins that require +12v on PCIe 1x. In the one you have linked there are two yellow wires, one for each side of the 16x connector, fed from the Molex connector. There are also two black ground wires which are used alongside the capacitor to signal a card is in the slot.
