hello, just a few questions conserning hardware issues.

[estesflyer]

ok, what is the difference between UDMA, and Ultra ATA ??
and... does it matter if you mix cables and hardware, etc...?

and i also have a peltier cooler, will it require a spare power supply?

i have a 350 watt power supply right now... very nice.

and one more thing...

on the back of most power supplies, it has a little switch, which you can fiddle back and forth to 115v, and 215 v, or something like that.
which does what?

btw, i heard that one socket only allows 12 volts, and that it doesnt really matter how fast your power supply is after a certain point...

that true??


gah, i know many peeps have their own opinions, and i have read craploads of sites about which is better... BUT...


cable vs dsl.... any suggestions for a small webserver?

DMA stands for Direct Memory Addressing, and ATA stands for AT Attachment. AT means Advanced Technology (the name given to PC's based on the Intel 80286 processor!).

Ultra is a nice buzzy word that doesn't really mean anything - much like mega, super, hyper - it merely implies it's the best available.

OK, no opinions here, just facts:

Here's a good document which will tell you about Ultra DMA

http://www.wdc.com/products/drives/drivers-ed/udmatp.html

And here's a good one about ATA, with some in-depth links

http://ata-atapi.com/

Your Peltier unit won't need a separate PSU - you should be OK with a 350 Watt unit. Some Peltier units require up to 72 Watts, so just make sure your PSU can deliver 12-14 Watts at 12V and you'll be OK.

The switch on the back is to adjust for different currents - in the UK we use 240V AC and in America they use 110V DC. If you're in the UK, DON'T switch it to 115V, unless you're really tired of computers.

Fast power supply? I don't understand what you mean by that!

I like cable for my webserver, but I guess it's down to taste. A lot depends on how good your ISP is.


Good Luck!

I hope the 110V "DC" was a typo. We in America use 110 and 220VAC with normal plugs, not those weird U.K. plugs. jk =)

the 220 and 115 I think is to what he was reffering but not that is not speed but volts Ac and I think it CitrixEngineer cover ata and udma well. and cable vs. dsl both give you about the same what is more important is the plan and the company you get the service from some companys have hugh penalties for going over a byte limit and you don't want that with a web server and in SOCAL where i live we a problem getting verzion out to install DSL it was going on 3 month before i just went with cable which took less then a week for them come out and insatll. So long and thanks for all the fish.

ok, so... I talked to the network administrator today @ school, he said that you can blow out a power supply if you use 110 in europe.

would it matter to use the 220 here in the US. ?

anyways, let me re-ask this question, using different words.

ok, does it matter if you use a udma cord for your secondary IDE cable, and an ultra ata cord for your primary ide cable... ?

hrmm... yeh, i ment power, not speed for the power supply.
like, would there be any more power in a 500 psu, than a 350 psu... because of the wall socket only allowing a certain amount of electricity running through it.

well,

TIA

Power available is a function of what the power supply converts. Ususally 200 to 350 watts. Wall plug can furnish enough (1600 roughly) to run 4 computers at full usage.
Some power supplies will absorb enough through the 220 volt circuits (switch changes where the input power goes in) to provide power from the 115 volt wall socket. Some won't. But you can get some wierd failures.
CitrixEngineer said 12-14 watts at 12 volts. Meant 12-14 amps at 12 volts which corresponds to 150 watts roughly of the 300 available. PS specs total wattage but sub specs give current available at the various voltages. And you need to provide the minimum required for each individual voltage. See your specs on the MB, the video card, the floppy, the hard drive, and the cdrom. Ed Fair

Any advice I give is my best judgement based on my interpretation of the facts you supply.

Help increase my knowledge by providing some feedback, good or bad, on any advice I have given.

Those 3pin UK plugs are the safest, ever! 230 volts can KILL if it gets onto the case and you get hold of it - hence the earth pin connector - the third lead - which will blow the fuse if volts ever get onto the case.

Having been unfortunate enough to get latched on to the 6KV overhead power lines by mistake, my life was saved by that earth lead!

/me guilty of unspeakable typos :~/

110/115V AC, of course.

12-14 Amps.

Here's another good article to make up for it

basweek,

those funny UK plugs you mention are not that daft ( really), the 3rd pin is for Earthing so its a lot safer than your fangled 2 pin jobbie.

If in doubt get the Ball Pein Hammer out

It took long enough for a response. I thought my little joke had slipped by. Thanks for the laugh.

p.s. Us yanks also have a grounding pins on our plugs that serve as a good chasis/earth ground; however, us rednecks in Alabama tend to cut those pins off if to make them fit our older plugs.
