Will this configuration work?

Hi everybody,

Some time ago, I decided to build my first pc:

-PC Case: Antec 1200
-Motherboard: Asus P5N-D 750i SLI
-Processor: Intel Core 2 Duo E8500 3.16Mhz 6MB
-Ram: 4GB CORSAIR TwinX XMS2 DHX [TWIN2X4096-6400C4DHX]
-Graphic Card: ASUS EN9800GTX+ DK/HTDI ( GeForce 9800GTX+ 512MB 2xDVI HDTV HDCP )
-HDD: Seagate Barracuda 640GB
-SATA: DVD ± RW 8.5GB SONY DRU-865S LightScribe - Retail
-PSU: Antec NeoPower 650W Blue

My question is, I wanted to buy a second graphic card ASUS EN9800GTX+ DK/HTDI to enable it in two way SLI.. But do I have enough power for it with my actuall PSU Antec Neopower 650? I'm actually a medecine student and I don't understand much when it's about power supply(only the one of the human body), so please if you could give me some tips I would appreciate.

Thanks a lot.

  1. Where are you ordering from? Whats your budget?
    The motherboard you've selected features the 750 chipset which has gotten some bad reviews.
    A 650W PSU will be enough for 2x 9800GTX+ in SLI.

  2. The PSU is powerful enough. However, it only has 2 PCI-E connectors and IIRC each 9800GTX+ needs two connectors. Check your card and your PSU. If the PSU has two PCI-E connectors and both are used by your existing card, then you need to buy two adapters like this:
