Windows 7: Power supply and JPWR2

Power supply and JPWR2

I am building a computer using a Antec 430W power supply and a MSI Z77A-G41 mobo.

The CPU power connector on the board (JPWR20) has 4 +12V positions with grounds. The power supply does not have a 4 (8) position connector--it only has a 3 (6) position connector.

Do I have to buy a different power supply or will I be able to use the connector with just 3 +12V supplies?

(I guess this should have been under Hardware and Devices)

You will need to have an EPS12v power supply (ATX12v/EPS12v) to have the 8 pin CPU connector.
Sounds like the Antec 430 is just an ATX12v supply.

And no, you can't get by with just a 6 pin connector.

Thanks for the reply TVeblen.

I have ordered this PS based on the fact that the specs say EPS=1:

What video card do you intend to use?

Yes, that looks to have the 8-pin EPS CPU connector.
What Layback Bear is getting to is that the Corsair has only one PCI-E video card connector and 430 watts. If you are going to be using a video card that requires 2 PCI-E connectors and more power then you will be stuck again.

Give that man an answer!

This is not a gaming machine. It will just have the Intel (3470) 2500 integrated graphics--no separate video card.

I appreciate the info that I would only be able to upgrade with a card requiring one connector.

This does bring up the question as to whether a cheap video card with DVI would give better performance than the VGA which this mobo has. Does DVI video outperform VGA?

VGA is analog output while DVI and HDMI are both digital output. Digital output has some advantages.
But performance is largely due to the power of the graphics engine built into the motherboard or in the video card. So you need to compare the specs of the graphics engine in the motherboard to any 'cheap' video card you may be thinking of. The motherboard could outperform a cheap card.

No he meant a 3470 processor.
