is what i'm using - its a sleeved cable PSU with modules, so you only install the cables that you need for your system, which I like a lot. 650 watts SLI readyhttp://www.newegg.com/Product/Product.aspx?Item=N82E16817153040&nm_mc=OTC-C173T&cm_mmc=OTC-C173T-_-Power+Supplies-_-Thermaltake-_-17153040
- newegg price
Its at a price delta too that is pretty affordable for the quality you are getting - I highly recommend it, i'm very happy with it so far.
video card, i'm using SLI 8800 GT's from EVGA - but a lot of people recommend 8800 GTS 512 mb for a single card solution - i'm pretty happy with my configuration; i've used a single 8800 GT in my system and found it to be an excellent performance card for the cost - on a 19" display at max settings i'm sure you'll have minimal issues with either an 8800GT 512 or an 88800 GTS 512
