Building my new rig and need a little help. I have a Corsair 520 PSU. In addition to the 24-pin main power connector it has a 4-pin 12V and an EPS12V connector. My MSI P6N SLI Platinum has an 8-pin socket with a removable plastic plug over 4 pins. This is identified in the manual as a 12V plug.

Do I plug the 4-pin in or remove the little plug and plug the 8-pin in? Will a mistake cause my new build to be engulfed in toxic flames? Or does it even matter at all?

Cheers.

Pull the tab and install the 8 pin, the tab is there for those who only have a 4 pin power connector and the board maker wanted to make sure you installed that 4 pin in the right sockets.
The 8 pin should give you a little added stability, but not much :p

And only if the processor's current draw strains the maximum current support through the 4-pin ATX12V connector. This would only apply to the Intel models with TDP greater than ~ 100W.

I have the 620 and my P5B-D has this connector so I used the 8 plug just to be ultra safe!

Not at the 65W TDP of your E6300. The ATX12V supply is more than sufficient for this.
