Yes. I think the cords are rated at 16A.
I plug it in place of the electric clothes dryer when I need to use
it. Moving it is a bit of a chore (200+ pounds) so I try to make sure
I *really* need it before doing so! :-/
[And, SWMBO complains vociferously of all the *noise* it makes -- along
with the heat it throws off!]
I thought you were running a minicomputer but a blade server is close
enough. I used to run a BBS with 16 nodes using the precursor to blades, an
Alloy server setup and an ATT 6300 as the main PC.
<<In 1984 Alloy developed the PC-Slave card which consisted of an X86 (8086
or V20) processor, either 256k or 1 Meg of memory and two serial ports. This
card used RTNX (later renamed NTNX) to use the host processor to act as a
file server. Dumb PC-Term terminals were attached to the PC-Slave to allow
the running of DOS programs. At the time it was much cheaper to use this
solution rather than network multiple computers>>
Each slave card was connected to a USR modem - they were very nice to my PC
group, donating first eight 2400 BPS modems and then when we expanded they
gave us sixteen 9600 BPS units at a time when those suckers sold for $500.
It was good PR because people who wanted to connect at what was then the
fastest modem in the world also bought them.
The Alloy unit wasn't nearly as powerful or capable but for its time, it was
pretty hot stuff. Really. We had to cut louvered vents into the door to
the tiny room holding the BBS gear and even that wasn't enough. We had to
have a ceiling fan installed.
This is similar, conceptually, to what my needs are. The difference being
my "nodes" are more loosely coupled; instead of an ISA bus that allows you
to "talk" to each of the cards, each card talks to the others over the
It's still cheaper. With multiple computers, you bring along more disks,
keyboards, monitors, etc. (even if you run headless). And, they take up
Yeah, I used a USR many years ago. Along with Telebit "PEP" modems to
talk to UN*X boxen.
Perhaps more important than the advances in cost and compute power that
have taken place over the years is the advances in power reduction!
E.g., my current design uses 500MHz processors that *could* run on

If I recall correctly, ArcNet was the only game in town at the time (1985).
CPUs are so powerful now that all you need is a multiport serial card to
drive 16 modems - not that anyone runs BBS's anymore. Even back then the
archtypical personalities of the Internet were emerging. The guys who truly
want to learn from each other, the guys who want to prove they're superior
to the rest of the world and the guys that just want to mess things up for
I switched all the desktops in my house to laptops with low power CPUs.
Amazing how much it lowered my monthly electric bill.
Yes, I keep threatening to do so. But, have way too many peripherals
that would be virtually impossible to support with a laptop; esp
a *modern* laptop! Also, it's a *huge* undertaking to reinstall
all the software currently on the workstations onto a set of laptops!
OTOH, on my ToDo list for today is to power down a workstation that's
been "doing nothing" (because I've not had a chance to get back to
what I was working on, at the time) and move the tools that I
was using (DTP) onto one of the larger laptops so I can do my
"editing" without having to burn all that power.
Not sure if cheaper, but easier way is use an adapters to convert the
IEC plug to a std 3 prong female socket (NEMA5-15R)
(Amazon.com product link shortened)
+1 Good find. The Newegg unit is cheaper than any other places I've found.
They're only $2 for 10 and offer $2 shipping (I think). At those prices,
using the adapters makes sense for at least low wattage applications. Now
that I've retired all my desktop PC's and peripherals, I've got quite a few
D cords so I think I'll order some from Newegg. Thanks!
Easier? Discard them and buy purpose made extension cords.
If you really don't want to wire a NEMA 5-15 connector to the wire,
you can remove the female IEC 320 connector and use the remaining wire
as a replacement cordset for power tools, appliances and lighting
Note that computer power cords use AWG18 conductors with an ampacity
of 7 (about 800 watts at 120VAC).
It's typically not worth the effort. You end up with a cheap, light-gauge
(low ampacity), short cord.
I have some longer (12-15 ft) 14AWG "modular power cords" that are plugged in,
permanently, in my office. They are handy when I need to connect some piece
of kit with a modular power inlet.
When faced with something with a genuine *plug* on the end (e.g., a wall
wart for something), I slip an adapter onto the cord that terminates in
a regular nema socket. In this way, getting the benefit of a "universal"
