Question about powering my first Mini ITX system

[EnergyFX]

I'm building a system to replace my father-in-law's dead Dell. Ideally I would like to use Gigabyte's Mini ITX desktop case with the built in monitor stand but I am unsure if the included power supply will be sufficient to power a Zotac GF9300.

The only other things going in the case would be one hard drive (7200RPM) and a DVD burner.

I can't find anything on power requirements for this MB. I'm wondering if the included 65w power supply will be enough or if I will need to upgrade to a 102w PicoPSU in order to use this case. I like the case because I can mount the monitor to it to make his system all in one.

You're going to need a better PSU, SilentPCReview did a bunch of tests with the Antec Mini-ITX case that comes with a 65w PSU and found that it isn't enough even for a low-power Wolfdale (E7200). We really need to know what CPU you're going to be using, for example, I have a quad in my Zotac board and I wouldn't use anything less than 250w for mine (even without the GFX card), but for an E5x00 or E3x00 a 100-150w PSU would be fine (as long as it's a reasonably high quality one, such as a PicoPSU)

Thanks, I was planning on using an E8500 but that is obviously not going to work.

Using PSU Calculator looks like a 150w PicoPSU will be just about right... but there is no room for expansion.

Update:

The 65W actually did much better than I expected. I had to downclock the E8500 to about 1.8GHz, and set all voltages as low as BIOS would allow (which really isn't much lower than stock) but once I did all that it actually became a stable system.

The 150w PicoPSU is nothing short of amazing! Runs the system rock solid at stock speeds. I doubt there is any room for an add-on video card, but thankfully it isn't need for this build. The onboard 9300 is plenty. The case doesn't have a slot for an add-on card anyways.

I am running a Q9400S with a 1.5TB Eco Green drive, an external USB DVD, an external 250GB HDD (2.5", USB powered) and a HD4350 on the Intel DG45FC with a 150W picoPSU. The system is 100% stable even under full load (Hard drives copying things, DVD copying something, CPU under 100% load and GPU at 100% load as well). With your setup you should be safe for a discrete GPU in the ~30w range (In the future it will mean probably low-end HD5XXX series).

Not that it matters since there is no way to fit a GPU there, but just so you know it is possible
