Power Supply Upgrade Question.

This isn't specifically Linux related as Motherboard/PSU related.

While I am waiting for Windows to update so I can get Fedora installed I thought I would post this question.

I just got my new computer. I have no complaints, except for one. The computer came with an Nvidia N630GT, PCIE x16 slot. It requires at least a 450 watt power supply. The one that was in it was only a 300 watt. No big deal. I had bought a new PSU a few weeks ago, 575 watt. I have everything installed fine on it. I am linking a picture to the motherboard In the top right of the picture you will see the ATX_12V 8 pin power connector. The original power supply had only one cable, 4 pin, connected to the bottom, (viewed in the picture as the left side.) The power supply I replaced it has two of these. I have one plugged in now but I am wondering if I need to, or should, have both plugged in even though the original set up only had one. Anyone have any recommendations or thoughts?

An after thought. The board does come with an ATI integrated (3000 series?) But since I am using the Nvidia N630GT I am obviously not using the onboard graphics.

The second plug for the ATX_12V (aka P8) is usually only needed for the 125 and 140W CPUs (or when you want to overclock, but that board is nothing I would use for that). It doesn't cause any harm to plug that in, so I would just do it.
The onboard video for that mainboard (Radeon HD3000) is neither well supported by the proprietary drivers (this card is deemed to be a legacy card, despite being still sold) nor by the free drivers. You will get decent performance with the free drivers, but no hardware video decoding. I would stick with the GT630, which is well supported and significantly faster.

Thanks. I will plug it in since it causes no harm. I believe the CPU is 90 watts. And yes, I love Nvidia. I have never owned any other 3D card other than Nvidia's cards. Now on to my next problem. I am making a new post for it.
