Why do capacitors fail?

Why do capacitors fail?

Bad capacitors are the bane of generations of consumer electronics. They plagued early 90s Amigas and Macs, early 2000s PCs, and cheap hardware even today. So why do capacitors fail? And how can you tell when a failed capacitor is a problem?

Capacitors fail when the electrolyte dries out, or when the gas inside them builds up to a point that it opens a safety valve and the electrolyte leaks out. A good capacitor takes decades to dry out, but a cheap capacitor can leak within a few short years.

With a power adapter, an 80mm fan, and some zip ties, it’s possible to add a case fan to a Dell Optiplex. The opening in the side panel is in just the right place for even a small fan to make a difference.

Budget folding rig

Budget folding rig

After running Foldingathome for a few weeks and watching my friends pull away and leave my machines in their dust, I decided to throw a little money at it and see if I could build a budget folding rig that wouldn’t embarrass me. While you can spend thousands of dollars on one, you don’t have to. Let’s see what we can do for a more modest amount. Like $200.

You can build a folding rig that can pull in 300,000-400,000 points per day for around $250. The trick is finding a decent minitower with a PCIe slot and a used graphics card.
