Can 20-pin power supply be changed to 24-pin power supply?

My motherboard is a 24PIN power interface, the power is 20PIN interface, compared, the more out of the interface is (+12V, +5v) and (+3.3v, GND) Two groups, now the motherboard only one +3.3v output used in the SATA power sockets, Want to use a large 4-pin socket to transfer into the 4-pin motherboard power connector, but the big 4PIN socket is (+12v, +5v, GND, GND), with one of the GND output instead of +3.3v can it? If not, consider using a large 4-pin to 4-pin motherboard power connector, OK?

GND indicates grounding, which is not possible in lieu of +3.3v output. Second, the large 4-pin interface only +12v and +5v output, while the motherboard of the 4-pin power connector requires both +12v,+5v and +3.3v, where the +3.3v is mainly memory power, so this transformation may cause the computer can not start, it is recommended that the user directly replace the power supply, this is more secure.

4-pin interface has three kinds of voltage, preferably do not use D-Port transfer
