That's pretty impressive. I had problems running about 6 case fans on my mostly-loaded full-tower i440BX system running off of a 300W Deer. How in the world did you not manage to overload the 12V line???
When I upgraded that tower to an Athlon XP1800 rig, the PSU died.
Anyways, my current rig, running off of a Codegen 350W PSU, for the last couple of years or so:
MSI KT4V-L mobo
Athlon XP1800+, TBredA, nominal vcore 1.5v, can run at 166 x 10.0 @ 1.525v, can't OC higher since mobo won't let me bump past 1.6v, and nominal for a true XP2200 is 1.65v.

(stupid MSI!)
WD 80GB, 160GB JB HDs, Maxtor 250GB DM+9 HD.
Lite-On 52x CD-RW, Creative 2X DVD-ROM
Afreey 56X CD-ROM, NEC ND1300A DVD-RW
ATI Radeon 9200 AGP 8x 64MB
WinTV PCI
Promise Ultra100 TX2 PCI (for the HDs)
Aureal Vortex2 PCI
USB1.1: couple of hubs, PS/2 keyboard + mouse to USB adaptor, USB optical mouse
USB2.0: WUSB54Gv1 WiFi NIC
Now, I actually have been having some rather strange wierdness quite recently, and I'm suspecting that it could be the PSU somehow. After burning a CD in the Lite-On, right after it started verifying, the entire machine froze, and the eject button on the front of the drive wouldn't work. Nor did the CD slow down after a few seconds after not being accessed - the firmware on the drive itself had hung too! Very strange. Now, this is after recent work I did on my system - I removed the 160GB, as it had problems in the past with resetting, it seems to have some mechanical issue with the power molex on the drive. I also recently added the WinTV and the Vortex2 back into the machine. The Vortex2 is disabled in Device Manager, since the Aureal drivers assume that the system chipset is a i440BX, and reprogram the chipset, which wreaks havoc with my KT400 and causes the most bizarro behavior and often, system freezes, in conjunction with the WinTV. I installed the most recent WDM XP drivers for the WinTV, and now, if I try to use it along with the USB 2.0 WiFi NIC active, my system freezes solid in a few minutes. Before the computer work, I noticed that with the USB 2.0 NIC active, my HD's burst transfer speeds reduced by about 1/3 when it was active. It seems to be hogging bus time somehow.
I just don't get how the CD-RW could freeze (firmware!), unless the issue was one of power, and perhaps the spindown/reset problems with the 160GB were simply that it was more sensitive to the problem than anything else in my system. Yet, even after removing a HD, I have the issue with the CD-RW, but not before? And I was still able to burn and verify a DVD in the NEC without a problem just now.
So, is it power? Or what? This system is getting due for a replacement, and other than the faster CPU speeds (good for games + emulators), it has been far less efficient and offered rather disappointing system I/O performance compared to my "ancient" PII 450Mhz on i440BX. I could burn disc-to-disc CDs at 32X on that - I cannot on my AMD/Via system. My max burst transfer speeds to my opticals via the chipset IDE is ~20MB/s, 23MB/s if I'm lucky. On my i440BX, it was ~32MB/s. Likewise, my UDMA mode 5 HDs only hit 77MB/s and 92MB/s (for the WD 160GB and Maxtor 250GB, respectively), and about 1/3 lower than that when the USB 2.0 NIC is active.
As much as I appreciate the price/performance that this system offered me (I had originally planned to snag an SiS-based Socket-370 with a Tualatin Celeron at the time), I think that I'm going to choose something other than an AMD/Via solution for my next upgrade. Maybe I'll wait for something with PCI-E that supports Dothan on the deskop. P4 is junk, Athlon64 is nice, but Via chipsets are garbage, NV aren't that much better. I want something with the performance and stability of an Intel chipset the next time around. A 925-based Abit supporting Pentium-M CPUs and PCI-E would be just the ticket, really.
Sorry, guess I drifted a bit OT for this thread. Oh yeah, the PSU is rated for 25A on +5v, and 12A on +12V. This mobo doesn't have a 12V aux connector, so I figured that should be fine. Also, I don't have MBM5 installing on this XP OS, but on W2K, I haven't noticed anything that would indicate that the PSU is overloaded or unstable, but I guess I should probably double-check that after my recent issues. (That, or just bust out the DVM, I wish I had a nicer one with a logging feature.)
