Just letting everybody know that my MPEG2 rendering issue is now resolved. I updated the PSU to an Antec 620 W High Current Gamer and everything is working fine.
A huge thank-you to Steve Mann for his excellent troubleshooting and advice. 🙂

This is an important post.
People underestimate now important having a clean power supply with ample power is. If you buy an off-the-shelf computer, chances are the manufacturer gave you a PSU that is barely sufficient for the parts they included. Then you add a few hard drives, more memory, and maybe a more powerful graphics card and suddenly you are out of power and the computer starts shutting down or rebooting randomly.
If you start upgrading parts on your computer, you need to think about upgrading your power supply as well.
Thanks Kevin for bringing this up and getting back to us.
I totally concur. One curse that comes from knowing PCs is that I’m constantly being asked to fix PCs… the good part, of course, is that I can offer advice to a large group. The single largest problem I’ve seen over the years are power supplies.
And John’s spot on.. the PC business is so competitive these days, everyone’s scrambling for cost reductions. The PSU is an obvious target for a PC, because studies show that users rarely upgrade their systems. It’s certainly dishonest to ship a PC that doesn’t support the maximum power requirements for every slot and port on the thing… doesn’t mean it won’t happen. And these days, even that’s not enough, since thanks to the sideband power connectors (cables run directly to PCI and PCIe cards), there’s no actual maximum per port.
Any engineer building a system will do a power budget — take the worst case power consumption for every device in the system together, add in the max for any other open slot, and then multiply by 1.25 (I would never put together a PC with less than a 25% over-design on the power supply, just on principle).
And of course, you can also buy a system today that’s perfectly well designed. But give it a year or two, upgrade the CPU, upgrade the graphics card, and that new tech may be sucking down more power than you could have years back.
The industry hasn’t helped here. The original PCI bus had a simple indicator for any card to indicate at least one of four zones of power consumption, but this was rarely if ever supported by manufacturers. And with nearly everything auto-configured these days, your PC could have a really good idea of the power demands versus the actual PSU. But no one in the PC biz championed this, so it’s still kind of the wild west, when it comes to even figuring out power consumption.
