Another quick question. I need to know where I can get a really small PSU, and how many watts it needs to be to run the following.

VIA EPIA 10000 Series MB (not sure which one as I don't really know the difference in the MII and the Nehernia once)
A 5-6" LCD Screen
200GB 7200 RPM HDD
A DVD/CDRW Combo Slot Load Laptop Drive
A small linksys hub (7.5V/1Amp)
512MB PC3200 DDR (one stick)
USB Bluetooth Keyboard/Mouse
1 or 2 Fans (size unknown at this time)

I think that is all I am putting in it.

SO can anyone tell me how big I need? I know the PW-60 PSUs are probably way too small, but I need a really small PSU to fit in this case.
 
i love mini-itx
I think you can run a standard ATX powersupply, I'd go with at least 250-300 to be safe. But the atx powersupplies are large for a ITX, but if you dont mind.... Nonetheless, here is the breakdown:

Component Requirement Line(s) Used
AGP Video Card 30 – 50W +3.3V
Average PCI Card 5 – 10W +5V
10/100 NIC 4W +3.3V
SCSI Controller PCI Card 20W +3.3V and +5V
Floppy Drive 5W +5V
CD-ROM 10 – 25W +5V and +12V
DVD-ROM 10 – 25W +5V and +12V
CD-RW 10 – 25W +5V and +12V
7200rpm IDE Hard Drive 5 – 20W +5V and +12V
10,000rpm SCSI Drive 10 – 40W +5V and +12V
Case/CPU Fans 3W (ea.) +12V
Motherboard (w/o CPU or RAM) 25 – 40W +3.3V and +5V
RAM 8W per 128MB +3.3V
Pentium III Processor 38W +5V
Pentium 4 Processor 70W +12V
AMD Athlon Processor 70W +12V

I don't know the draw from the itx mobo cause a lot of stuff is built in, video/sound/cpu..you know

At www.mini-itx.com they have the special adapters that are like 130watt or something small, but it looks like a charger for a laptop, small black box thing..


Goodluck, let me know what you've decided on...
Also, I've been looking in to buying one of those but i dont need a 1ghz one..have you found any places for a good deal on one?
 
Just get one of those shuttle PSU from newegg. Any ATX PSU will work, mine came out of a compaq.

Here they have done power tests, so lets say around 30Watts consumption for the MB.
  • All rounded up:
    30W for MB
    30W for DVD/CDRW
    25W for 7200 HDD
    10W in fans
    20W in RAM
    10W LCD from Sony
    10W Linksys Hub
    ~140W Total

Sound Good?

Then we have the LCD Display, I need to go look that up. I think I am gonna use a Sony PSOne LCD if I can find one.

Edit: Ok well according to the doc from sony the power brick for the little 5" LCD screen is 7.5V. The doc also says 6.8W power consumption.so thats not bad.

Edit2: From Lynksys: the 5 port version runs a 7.5V @ 700mA; 7.5*.7=5.25W so lets call it 10W. A hub is ok right, or should I find a switch?
 
Thats what I am looking for is a 1U PSU for a rack mount server.

The box I have is like just wide enough for the MB to fit in so its like 8" wide.

I am thinking I will just get a 1U 200w PSU, if I can find one, then hack off all this crap I don't need.


What are y'alls opinions on these VIA EPIA boards? I have seen some bad things about the audio and video. I was hoping to run this one as a small LAN server, and File Server, plus my carry along PC Analyzer so when i got look at people computers :)
 
It'll work like a champ in that situation.

Pretty much anything not requiring high end graphics or a serious audiophile they work really well. And with the right PCI card and USB/Firewire devices they can usually be made to work for anything except 3D Gaming. For your situation you might consider the CL server boards, or just the basic V10000. The only thing that the M or MII would gain you is the second IDE connector. The CL gains you another on-board network connector, and supposedly higher-quality (server grade) kit.
 
Ohhh, I just saw the mini-itx board for the P4, hmm, that might be better. Its the same size 170mmx170mm, but it holds any P4 chip.

That would overcome all the possible speed issues. But it does use a savage video set :p


Hmm, gonna have to think about one. Wonder where my income tax check is anyways???

*runs to mailbox*Nope empty :(

Click to expand...

1. Why power the hub off of the PSU? :rolleyes: 10 watts in fans is ohh say a couple of Vantec Tornados or TT Smart fan 2s. For an EPIA system, I don't think so. 25 Watt HD? Nah, more like 500ma on the 5v, and same on the 12v, which is more like 15 watts tops. Same for the DVD, you're over shooting that too. So if you get the 140, you'll have breathing room, but you possibly could go wit more like 120 and still be fine. YMMV
