Silly question about power supply

[Chris A]

I had to buy a new power supply. My main board has a 4 pin power connector. The power supply has two 6 pin connectors on seperate lines.
There is one line that has two 4 pin connectors that are real close together one is marked 4+ and the other is marked 4P The two have arrows pointing towards each other.

What cable do I use one of the 6 pin connectors?

The power supply is a Rosewell RG630-2

the two 6 pin power connectors are for pci-e 16s videocards. Use one of the 4pin power connector. The two 4pin connectors will only fit in one way. So only one of those 4pin power connectors will fit into the 4pin plug on the motherboard.

Good luck with that PSU. Rosewill are on the lower end of PSUs.

They both fit in pretty easy. Both connetors are on the same cable. Never seen one like this before.

The only reason I can think of for two four-pin connectors in the same bundle would be to build an eight-pin connector for the motherboard 12V connector. These connectors are either four-pin or eight-pin. Normally, you can use a four-pin cable in the eight-pin connector without problem, but it needs to be in the correct position (probably the connectors are shaped so you can't get it wrong, but I've never tried it).

There is nothing strange about the cable configuration. Many PSUs have the 4+4. Some even have a dedicated 4 pin and a dedicated 8 pin connector for the CPU. The 4+4 is is a nice flexable way to offer support for the old 4 pin and the newer 8 pin CPU connector. On some older boards its had to use the 8 pin in a 4 pin connector sice there may be components in the way of the last 4 pins hanging off the side.

Yes the connectors are keyed so you can't plug it in wrong. So long as your not using an excessive amount of force. For your motherboard use the side of the connector labled 4P.

Thank You all.
