I'm going to build a cheap computer inside an Acer Aspire 3200 case. Are Acer PSU's compatible with other components? I am going to use a Celeron 1.2 256K, WD 40 GB 7200 HDD, 2X 256MB Simpletech PC133, a 4X CDROM, a floppy drive, and whichever tualatin motherboard with onboard video and ethernet is cheapest on newegg when I order.

The Acer PSU is a Tiger 140W. I want to be sure nothing is going to fry because of the PSU before I order the components and put them together.

i think you will need a larger power supply like 250

This is a Micro ATX case with SFX type power supply, correct? These are a small form factor power supply with standard ATX outputs, they work on nearly any board. As for it being 140W...that's fairly small, it would probably work with onboard video however.

What happens if it doesn't work? I don't care much about the PSU itself, but could it fry some of the new components?

Doubtfull, if you did you could be a slightly better replacement.

I've recently put together a mpeg 4 encoding box -
Chyang Fun E-note case w/150w PSU
Pentium 4 2400/533
Commell LV-670
1x 512Mb PC2700 (non-crucial micron)
Maxtor DM9 120Gb/8Mb
Pioneer DVR-106

The only worry I have is with the 12v rail, it's nominaly ~11.2v droping to ~10.9v (read by a multi-meter) when burning DVD's but the system is yet to crash. So as long as the PSU is as good quality as the E-notes unit I don't see there will be a problem.

I just found these numbers on the PSU, do they mean anything?

+5V max A = 15.0
+12V max A = 3.0
-12V max A = 0.3
+3.3V max A = 12.0
5Vsb max A = 1.0

I noticed that a lot of the new PSU's seem to have 10 A for the +12V, will that make a differece?

they're the key to the max avaible power on each rail, but what is missing is the total max on the (3.3v,) 5v & 12v rails.

12x3=36w (+12V max A = 3.0)
5x15=75w (+5V max A = 15.0)
3.3x12=39.6A (+3.3V max A = 12.0)

-12x0.3=-3.6w (-12V max A = 0.3)
5x1=5w (5Vsb max A = 1.0)

5Vsb is the power supplied to the mobo when the machine is 'off' (ATX machines are never totally off until you've unpluged from the mains) to monitor events (power button, keypress etc) which can turn the PC on. I have no idea what the -12v rail is used for, but the +12v rail is very week & will probably be a very big problem.
