What parts of a computer uses +5V (was: What parts .....)

 

What parts of a computer uses +5V (was: What parts .....)

 

I replaced the subject line with a more informative substitute. Why

this wasn't done in the first place is beyond me.

The +5V supply is the most used supply from an amperage point of

view. Pentium 4's use massive amounts of +5V (it gets converted down

to 3V and lower depending on the exact model). Hard drives, optical

drives, floppy drives also need a +5V supply (in addition to a 12V

supply, which is the next most-used supply in terms of amperage).

According to the software Speedfan, the +5V is actually 6.92. Your opinion

please.

+6.92V or -6.92V ?

b11,

 

I have know idea what possess you to perhaps build you own computer, or

upgrade upon, or both.

 

Be prepared for a number of small failures along the way,(some not so

small), but they *are * the stuff of learning, **not** successes.

 

A number of years ago people were purchasing replacement Dell PS, or maybe

purchasing replacement Dell mobo's. What nobody ever thought to tell the

consumer is "sure I'll sell you a new PS..Oh, forgot to tell you the mobo

*would not* electrically fit. The power connectors, everything appeared to

be identical

 

The moral is, it took a number of extremely trained eyes in the field to

discovery the Dell had simply changed a pin-out. C'mon, would have thunk

it.

 

In Dell's defense, after many a fried mobo, power supply, or BOTH, Dell got

their act back together, and one again are selling parts that "should" go

together , go together once more.

 

If you have not already done so, go to your local Barnes&Knoble, and Buy a

copy of Scott(sic) Muellers' "Upgrading and repairing PC's. By now it is

probably getting close to the 20 edition. It's not cheap $55-$65 usd. The

material, the theory listedtherin *never* becomes wrong--just a little

dated.

The usual tolerance that is acceptable is 10% - in this case that means 4.5v

to 5.5v. 6.92v, if it's real, is well out of spec.

 

Use a decent digital multimeter to test it a various points around the

circuitry.

I know Jeff had probably forgotten,

 

But be sure to measure voltages with a VTVM (if you can still find one), or

better get a DMM(digital multi-multimeter). It's essential when measuring

voltages *that* small, that the internal resistance of the meter can throw

the accuracy quite a ways off. A good rule of thumb for DMM's is 15

megohm/volt input impedance. I purchased a little gem of a knock around

DMM, available at most automotive section, (Target, Wal_mart) for under

$20USD

I can NOT believe no one found my joke funny. :-(

 

AFA the OP, I think it's a perfect case of "a little knowledge

is dangerous thing". But he is apparently quite determined to

blow up his machines.

You're right!. Sorry, but I completely missed it.

 

Obviously Speedfan is measuring the potential between the +5v and the +12v

rails. How on earth he arranged things to end up like that I can not guess.
