      I had a CF to IDE adaptor that was "semi-hot-pluggable." What they meant was it was hot-unpluggable, but if you tried to plug anything into it while hot you were going to crash your system in a mighty hurry.

      Ironically, this one was 10 dollars more than the non-hot-pluggable one, but I never found any advantage in it.

      Well unlike the USB plug, which is designed to be hot-pluggable by setting the data pins back 1mm from the +5V and GND pins, the PS/2 plug can be inserted in a way that mates the +5V and data lines before the GND is connected. I've certainly experienced hangs, reboots, and sparks from hot plugging PS/2 cables, and a cousin once needed a new power supply after doing it.

      Google searches turn up similar warnings, so I don't think it's a superstition.

      If one wants to hot plug a PS/2 connection I'd suggest: (1), keeping the plug as perpendicular to the socket as possible, and (2), inserting as rapidly as possible.

    Not totally true.

    My PC had a cheapo 250 or 300 watt PSU that came with the case (case+cpu was like $25 total)

    i moved to my current apartment and within a few months the PSU blew. All the capacitors popped, fan died, smoked and smelt up my room. Luckily it was just the PSU that died

    So I got a nice expensive PSU.. 6 months later i noticed the voltages were dropping on my monitoring program.. i thought it must be a mistake, bad sensors or something.. But it kept getting worse.. Until a couple of months ago when i noticed tons of RF interference with my TV tuner..

    Then last month my hard drive would occasional click off then instantly spin back up and lock my pc.. a reboot would fix it for several days

    Then last week, click, spin up, lock.. reboot, click, spin up, lock, reboot, etc.. the PSU could no longer power my hard drives

    Why? Crappy wiring in my crappy apartment. Brownouts and surges. So I bought another PSU, and now an APC LE-1200 line conditioner/voltage regulator. It's working great.. except I found out the outlets in my room are not grounded (the voltage regulators Ground Fault Indicator came on, so I plugged in a cheap AC circuit tester, it indicated OPEN GROUND, so I used a multimeter to confirm it, yep not grounded.. argh!)

    Wonder if thats why I always get static shocks whenever i touch stuff in my room.

    Anyway, i guess what im saying is even good expensive PSUs can go bad cause of crappy home wiring and whatnot.

      At one of my jobs, a client had a lab full of fairly new computers with cheapo supplies. I kid you not: within 1 year, 25 out of 40 supplies failed and in three cases the motherboard and CPU were destroyed in the process. When I came onboard, I made it a policy that any machine found to crash at random would immediately have its supply yanked and replaced with a quality one. (indication of pending failure..) User complaints dropped rapidly as reliability instantly went up.

      It's not even just stable rails. (although this is one indication of quality..) I've found by examination of fried supplies that the cheapo varieties don't have much in the way of protection circuitry. All power supplies die at some point. That's a given. The quality ones just die gracefully and don't take the rest of your hardware with them.

      As for price, the amazing thing is that there's not always that much difference between a quality budget supply and a total garbage one. I've found 300W Fortron (FSP-300) supplies in the $25-30 range. They're not top of the line, but I've yet to have a problem either.

    Additionally, reviews that place heavy/out-of-spec loads or nasty input power on PSUs tend to arrive at a similar conclusion.

    It doesn't. I did the math once on the Surge protectors I was selling at Sears -- the best one we had, with the $20K protection policy -- it could handle 2500 joule if I recall.

    Assuming room temperature and nice even numbers (so 25 deg C), that could boil:

    2500_J ~= 600 cal.
    600cal/(75deg C) = 8

    That is a whopping 8 ml of water.

    Modern surge protectors are to protect against in-home spikes -- buy them based on how much insurance you want, and ignore the power rating. But make sure they say that they cover lighting!

    I assume you got something like swamp cooler filters, or force-air heater filters? either should work well -- not so fine-grained as to get clogged with microdust, but sufficient to catch any lint, cat hair, etc.

    Last summer we had a ground strike at our neighbors house's backyard (about 75' from my house, about 10' from theirs). Trashed their house pretty bad, to the point of even melting a hole in their propane feed line. Nasty bolt

    So while I'm watching the fire department, cops, etc...show up at their house (The occupants were all scared shitless, but otherwise fine), I decided to go check the National Weather service. I had mistakenly forgot to turn it off before the storm, so I just sat down and started typing. Worked fine.

    Except it said the network cable was unplugged. Huh?

    Long story short: 6 (yes, 6) trashed NIC's, 1 trashed router, 1 trashed motherboard, 1 trashed VCR, and a trashed thermostat. Before you ask me about line protection, etc, consider this: the thermostat for the furnace is not on line power. It's battery powered. As for the computers and router: all are on UPS's. Big (2000VA+) industrial ones. Yes, Virgina, the power does suck where I live. The UPS's all reported a mild line spike (147v, if memory serves), but nothing crazy.

    As best anyone can figure (though I'm open to other ideas), the spike got in one of two ways: either though the grounding wires (which would make sence, except for the UPS's protecting that line, too, and that still does not explain the thermostat), or some sort of strange transient voltage created in the wiring of the house by having that much current and voltage passed so close (sort of like creating a big A/C alternator).
