Green wire and a black one

All you need

HigHTecHReDNecK · 19-December-05, 07:28 PM

Just make sure you tape it off good when your done, so ya dont short nothing out.

hartigan · 19-December-05, 07:30 PM

at the risk of sounding like a total n00b . . .

Why would someone want to do this?

I'm genuinely curious.

lol, NOOB

j/k . I for one did this so that i have a psu set up for testing fans and such its actually very convienent to have a psu set up like this and plugged in. When i want to test a fan or opticalk drive to see if it ejects or HDD for power up, i flip the switch on the back of my tester psu and BAM i got power. No need to open a case or anything.

hartigan · 19-December-05, 07:35 PM

Ohhhhhhhhhhhhhhhhhhhhhhh. Now I get it.

Thanks for the response.

Damn right!!
Great for leak testing watercooling gear too (so I've heard) and HEAPS cheaper than those fancy-pants plug things

but yeah - tape it off

THRiLL KiLL · 25-December-05, 12:38 AM

i use this method to run a second powersupply in my system...

Rockin'male · 25-December-05, 12:51 AM

I have to agree as well......
I did this on a cheap power supply to bleed all the air out of my watercooling system without turning it on.

Executioner · 25-December-05, 10:52 AM

I searched around but didn't find any guides on the subject.and as it turned out I totaly forgot I
about this thread and asked again somewhear else, my apologies.
as far as google, how the heck would you word that? I thought you could only search for websites?
(I got a sneaky feeling I'm gonna fet laughed at on that one)

Now you tell me.

I just recently threw away a psu from the case I am modding. I wanted to use it for the same purposes as you state above. This happened before I joined (or even knew of) pimp rig. Most of my searches warned not to play around with jumping the supply. I knew it could be done I just got tired of searching and having a useless psu sitting around so I tossed it.

musclecars&computers · 19-January-06, 12:36 PM

I've got the older ps's non atx that has a switch you flick and it works no, jumping needed.

Bionic · 19-January-06, 12:38 PM

Pimp rule #296: Never throw away computer parts

Seriously though, I keep an old 200W PSU sitting around rigged up like this all the time for testing things like fans and lights, and also to check my wiring on a switch before I install it in my rig.

You're cracking me up!

Thanks for the laugh!!!

I've bought this "bridged" connector which does the trick... was like 2 bucks...

Well now , when i first started messin' with pc's and such, i was WARNED about letting PRRFESSIONALS do things like changing my cpu, or MoBo etc etc.

THRiLL KiLL · 19-January-06, 02:58 PM

i found it 1st try =)

did search on: turn on power supply without motherboard

1st hit:
ATX Power Supply Wiring
As you know, the ATX power supply will not turn on normally without a motherboard
connected to it. There are times when you may want to test an ATX power ...

Just a tip for you guys, make sure to have a load on the PSU when you start it up this way. Having no load can kill cheap power supplies when they are turned on this way.

pwrslyd · 19-January-06, 03:43 PM

I'm thinking about doing this on one of the mods I'm planning to run the CCFLs and whatnot (gotta look icy

) and modding the PSU to look like a zamboni (any ideas about my mod theme?

Go Preds!)

hartigan · 27-January-06, 01:06 PM

is it always green and black wires or does it change from PSU to PSU

I just got an OCZ PowerStream 600 and I'd like to power it up, but it has a 24 pin ATX connector so would I still short the green and black?
