It has just ocurred to me that after a round of upgrades, my MDD PSU might be getting a little stretched. It hasn't done anything to make me think that is the case, but it started out as a single 1GHz FW800 with 133MHz bus and a Radeon 9000, 80GB HD and CDRW.
The 80GB failed, and the machine has had a variety of drives since.
Its new spec is as follows: Dual 1GHz, FX5200 (with extra fan), Pioneer DVR110, Maxtor 300GB, IBM 120GB and 60GB, and Seagate 30GB and 8GB HDs. Also has a PCI ethernet card and PCI USB 2.0 card. And Apple Pro Speakers.

Am I pushing it here?
