Plugs?

Is it possible to plug the wrong plugs into the wrong place? Like the 4 pin plugs.. all of them have the same output power right? My graphics card is acting weird. Like I go and play Half life 2 with normal settings and it gets so artifacty in a few mins that it looks like I'm in neos body watching him in the matrix thru his eyes.

EDITED: Also is there a tutorial on PSUs that tell you how to figure out what you need for your setup? Like enough info just so I could set it up on my own? Dont point me to the PSU FAQ please as it is 20 pages long unless theres certain sections just for what I want. Thanks!

of course there is a bit more to it than that
for instance doesnt address crossload yet and the various ATX12V versions
get a start then link up your config on the calculator and post what PSU you have, ideally along with more detailed info of your config

and

for the most part the connectors themselves are bulletproof
they are keyed to prevent incorrect attachment

however many graphics cards direct that the only deviced attached to a strand is the graphics card

with stock PCI-E video connectors they are on dedicated strands
if adapters are employed they ask you do the same using 2 typical 4 pin molex to power the adapter and no ither devices on that strand

So could not enough power to the card cause it to artifact? Ill post specs in little bit.
 
yup or another device on that lead either making the +5V or +12V fluctuate or adding "noise" to the power because its not sheilded

or the supply might not be putting out enough amps altogether
or the amps arent on the rails that you need
keep in mind that the supply's capacity drops as the temperature increases
and many supplies are rated at unreasinably low temperatures

so there are quite a few caveates, which explains the popularity of this forum
but we can likely get to the bottom of it, make sure to include everything thats drawing power
even down to the size and if you know it speed of fans

If theres any other info let me know and I can dig out the papers to all the parts I bought.
 
yeh if you look on the side lable of the PSU
youll see its amps per rail need the +3.3 +5V & +12V
 
+3.3V +5V +12V -5V -12V +5Vsb +3.3V & 8.5V
32A 32A 26A 1A 1A 2.2A 182W

What are the 32A ect? These just markings to tell you what rails are what?
 
watts divided by voltage equals amps (A)
that tells you how much capacity is available on each of the rails (+3.3V +5V +12V are the main ones to worry about the negatives arent typucally employed these dats, the +5VSB is just to wake on WAN, LAN or by keyboard)
(how much cuttent can be had at a given voltage)
you can easily have a supply with a total wattage capacity exceeding your needs but if the amps arent on the right rails still not power your rig
different compinents are powered by the various rails
some employ mire than one.

the 3.3V & 8.5 is a mistake, your or thiers, it would be +3.3V & +5V combined capacity is no greater than 182W


I'll work it up, hold tight ;)
 
OK first thing I checked was that your older mobo indeed powers the CPU off the +5V rail
there is no 4pin +12V mobo connect so that is true
http://www.asus.com/products/mb/socketa/a7s333/overview.htm#
then I looked up the draw of your video card
http://www.xbitlabs.com/articles/video/display/ati-powercons_8.html
http://www.xbitlabs.com/misc/picture/?src=/images/video/ati-powercons/t4.gif&1=1


so here is the theoretical maximum of all the draws
http://takaman.jp/D/?M=PaQbeH7SASkTZiH3kG5@lDvHFnG5HDYAZAZavXCMZ&english
this never actually happens since all the components never draw their full load at the same time
note the RAID listed is actually a 5th fan

drives and fans need there full amo rating when they spinup to overcome inertia
generally once they are spinning that drops to about a quarter of that
so a real word worsecase draw is more like

+3.3V @ 6.6A
+5V @ 13.6A
+12V @ 3A
180Warrs

and typical power draw is far under that
your supply is up to the task and a bit more, your artifacting is likely because of other devices on that wire strand

you should first try isolating the card and if that doesnt work you could consider one of these http://www.xbitlabs.com/articles/other/display/ocz-powerlead.html

You really are a super charged mod. You always responed before anyone else and help a lot whenever I need it. Hardocp is a great community because of great people. Thanks Ice Czar
:D

EDITED: I didt have a free rail and couldt make one free so I just hooked my VGA up to the rail with my CD reader and my floppy drive. It doesnt artifact as bad and I can play on high settings in Half life 2 with very little artifacts. Its good enough to hold me over tell I get my next computer. Thanks again.
 
Thanx :D

actually I should have qualifued my last statement more
if the artifacting is power related you should ect

it could be other things, drivers, too hot, damaged card ect. ;)

since the optical and FDD arent typically accessed that was a very smart move ;)

I thinkl? the optical may have a slight parasitic draw but it would likely be static (not changng) but the FDD likely has the least shielding too and could be pretty "noisy"
spinup the optical for an informal test

the supply itself has a certain amount of noise and that is an older supply
see Ripple >
http://www.pcguide.com/ref/power/sup/spec.htm
so its filtering might be a little degraded, and its just rated for spec anyway (doesnt exceed spec in ripple)
so its hard to tell if those OCZs would be a good investment or not
try the free stuff first ;)
