90W PSU my only option?

Hi gurus... I have just purchased one of those GallantWeb boxes that is essentially a tiny 810e board (FlexATX?) with onboard everything running a Celeron 633. It has one 20GB 7200RPM drive in it. The system is essentially a FIC Sahara 3810. I plan to wipe it off and use it as a NAS box.

The problem is that this thing has a Delta 90W PSU in it. It appears to be an extra small SFX style (about 5" x 3.9" x 2.1"). I have scoured the net looking for larger wattage power supplies with the same physical dimensions but haven't had any luck so far. From what I can tell, a 90W is all that will fit in this case.

So, given that limitation, is it out of the question to think that I could hook up two 7200RPM HDDs in this system? I know the original Sahara 3810 system had not only the HDD but also a slimline CD-ROM and floppy drive installed. Given that the GallantWeb doesn't have these, do I stand a good chance of squeaking by with only 90W?

In case it helps, the output of the PSU is as follows:

+5V 12A
+12V 2A

+5VS 1A
-12V 0.2A

Would it help to disable the onboard sound and usb? There is no AGP slot, and I will not be using any PCI cards since video and ethernet are built-in. As already stated the chip is a Celeron 633MHz with a passive heatsink.

Believe me if there's a way I can get a higher wattage PSU I'd do it in a heartbeat. But barring that, if 90W isn't enough power to feasibly power two 7200RPM HDDs + the mobo then I'm going to scrap this project.

Much appreciate any advice or insight!

Thanks for the response. I only wish it were that easy. The one you linked is 4.9" x 3.9" x 2.5". Believe it or not that extra .4" of depth will cause it to not fit in the case. In addition it has one of those 80mm fans that adds another cm or so of depth to it (they didn't account for that in the dimensions listed).

Thanks anyway!

Um, try it and see?

My money says it'll work. A HD usually isn't more than 1A on either the +5 or +12, and there's not going to be much else on the +12.
