I Have a PSU that only has 1 8-pin connector, which I have a motherboard and a GPU which require 1 each. Ive notices the PSU have two 4-pin 12V connectors. Can I put two 4-pins where there should be an 8-pin connector? ( Will this work/Is this safe? )

Yes that will work just fine.

The 8pin/4pin confusion is a result of overlap between the ATX12V PSU standard and the EPS PSU standard. Both the ATX12V and EPS standards specify a 24 pin main power connector. In addition to this, ATX specifies a single secondary 4 pin auxiliary power connector. EPS on the other hand specifies one or more 8 pin auxiliary power connectors and an optional 4 pin tertiary connector.

The secondary connectors are key compatible, which allows a 4 pin ATX...

In addition to this, ATX specifies a single secondary 4 pin auxiliary power connector. EPS on the other hand specifies one or more 8 pin auxiliary power connectors and an optional 4 pin tertiary connector.

The secondary connectors are key compatible, which allows a 4 pin ATX male (from the PSU) to be inserted into half of the 8 pin EPS secondary or the 4 pin EPS tertiary (if present, only high end motherboards have this).

Most motherboard and PSU manufacturers have designed their products to accommodate both standards. Motherboards typically have an 8 pin secondary which can be used with ATX and EPS PSUs, and PSU manufacturers often split a cable into a 4+4 which can be used for either an ATX motherboard or an EPS motherboard.

Fun stuff

EDIT: As a side note, the 8 pin EPS secondary connector is not the same as the 8 pin PCIe connector. They are keyed differently and cannot be used interchangeably.
