Mobo/Power question

[brnbngls]

Ok, I have a Soyo SY-6BA+ motherboard (two actually), brand new. I also purchased a cheap case (didn't realize how cheap when I did). The power supply in the case is only rated at 160W output. What's happening is, the fans spin up as well as the hard drive, but nothing happens after that. No BIOS, no nothing. I get no screeen output. Could it be that the power supply is ineffecient for this board? If so, why would the fans and everything else spin up but I get nothing? Please advise, this is a Christmas gift and needs to be done ASAP. Thank you.

Logically:

If the fans spin, the PSU is alive.

Assuming its an ATX, there needs to be a connection between the power switch -> Motherboard -> PSU. This should mean that the mobo and PSU are all ok. Something must be stopping it from posting.
- Dead chip?
- Half dead mobo? (ie: something crucial is wrong, but the signal still reaches the PSU.)

Anyone got any ideas ?

Well of course the fans spin up they use minimal power. I wouldn't try and get it to work with such a cheap PSU.

160 Watt - ewwch!!

You trying to use the 160 Watt PSU? What extra hardware (CPU, graphics cards etc) are you trying to power? I'd say that the PSU is nowhere near powerful enough.

Double Post....

Ok, that pretty much confirms my suspicions. I'm trying to run a PIII, ATI Radeon 7000, Western Digital 60GB drive, Standard CD-ROM, CD-RW, NIC, Sound Blaster Card, Floppy Drive....I think that's it.

The site that I purchased the case from says is a 250 W PSU. But wouldn't it say that on the label? Rather than 160W? Or is 160 the average power? Here is the Link

*edit* This is the email response I received from Computer Geeks:

Thank you for your email. this is a 250watt power supply the line on the
power supply that says

XX +5V N +3.3V TOTAL O/P 160W XX +5Vsb=1.0A XX

this only means that the total output for the 5 volt and 3.3volt
connections can only be up to 160 watts if it goes any higher than that
the power supply
will shut itself down

To find out the true amount of power that this power supply has you can do
a little math. The way you do that is to multiply the volts by the amps of
every line on the sticker on the power supply and then add those number
together. For example, let's say your power supply says this:

{ USE THESE VALUES } {DISREGARD THESE VALUES}
+3.3v +5v +12 +12v -5v +5vsb com p-on pg
14a 22a 8a 1.0a .5a pur blk grn gry

You would multiply +3.3 by 14 (46.2), 5 by 22 (110) 12 by 8 (96), absolute
value of -12 which is 12 by 1.0 (12), absolute value of -5 which is 5 by .5
(2.5). Then you would add those numbers together.

46.2+110+96+12+2.5=266.7

So the total maximum output for this power supply is 266.7 watts.

Go ahead and perform these calculations on the numbers you have on your
power supply and just verify that it is at least 250 watts.

Does this look about right? Am I going insane? Suggestions?
