Power supply and JPWR2

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:

CORSAIR CX series CX430 430W ATX12V v2.3 80 PLUS BRONZE Certified Active PFC Power Supply - Newegg.com

(Front page on Slickdeals .net)

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.

The i5 2500K has Intel HD Graphics 3000.

A misunderstanding?
