Sufficient Power?

[Guest]

Taking the following components into consideration, is 120w sufficient power for the proposed system?

1. i7 (800 series) compatible mini itx board: http://www.newegg.com/Product/Produ...gle-_-Motherboards+-+Intel-_-ZOTAC-_-13500043

2. Mid range GPU: http://www.buildyourowncomputer.com/page/B/PROD/96728S

3. SSD and HHD one Intel and the other a 7200 rpm high capacity drive: http://www.newegg.com/Product/Produ...Froogle-_-Solid+State+Disk-_-Intel-_-20167025 and http://www.newegg.com/Product/Product.aspx?Item=N82E16822148337&nm_mc=OTC-Froogle&cm_mmc=OTC-Froogle-_-Hard+Drives-_-Seagate-_-22148337

I hope that this configuration won't starve any of the components of power. I'm having a difficult time finding any DC-DC/external AC-DC adapter kits that provide above 120 watts.

120 Watts? Is this a typo? Are you referring to a laptop or a desktop? (the HDD listed is a 3.5" desktop type of disk)

I hope 120W is a typo, a 5770 can pull about 100, and an i7 860 would pull about 120, so you need WAYYY more than 120W of power, i wouldnt put an i7 in a mini ITX build, thats a lot of heat and not much space, go micro ATX and get yourself a reasonably sized PSU to go with it like the corsair 400CX.

I know it's crazy. But this is a mini itx build I'm talking about. The most powerful embedded power supplies only go up to 200w.

(The HDD is listed as a reference in terms of power, I plan on using a smaller one of similar performance.)

This will work well and also provide for some modest future upgrades: http://www.newegg.com/Product/Product.aspx?Item=N82E16817139004

Why didn't I think of using a non-embedded power supply? That should work perfect. It will look like hell under a desk but I think I'll feed the wiring through a cutout into the slim mini itx case.
