A tester such as the following is not only cheap but very easy to use. I am not sure if it was suggested but for what it's worth, I'll add this link. http://www.atruereview.com/powersupply_tester/index.php Regards, John O. I have a tester that let's you use a meter to get the actual voltages. But, you can't have it hooked to the motherboard since, like this tester you show, you plug the power supply directly into it.

You have other obsolete equipment. Stuff that probe into
the connector of one obsolete power supply. Nylon expands and holds probe in place. As probe is removed, then nylon returns to original shape. Worry more that you will have a heart attack. Stuff that probe in. Notice no damage. Do what we have been doing long before you even existed. Somehow I feel I am watching an episode of Fear Factor. Its only a probe. Stuff it in and read the numbers - when power is off, in the seconds that power is turned on, and as power stays on.

I just sold the majority of my old junk around Christmas to a guy that wanted a system for his kid, P4/1.7, 80g hd, 845 based mobo, antec case, 52x cdrw, 512mb mem, basically a hotrod from 4 years ago. They were happy and I got some coin out of the deal. S Oh, I wish you could see the boxes of junk I have. Would you believe an old 120MB hard drive? Yep, it was top of the line in its day. I got a 386SX board in a box if anyone wants it. ;o) This computer I'm looking at is turning out to be quite a dinosaur too. Just checked the hard drive. Seagate Medalist Pro 2520 (2.5Gb) so, I think the ole 200Mhz might just work out fine for her. I'm gonna stick a Diamond 4MB video card in it and floppy drive and see if it will boot up to a floppy. Then we'll go from there. Darn, I gotta get rid of this old junk! ;o) Patty If you really get longing for the old days, I can send you some of my old double spaced 10meg MFM or RLL drives. God only knows why I still have them. Perhaps during the summer I can strip all conceivable spare screws and connectors from them and ditch them and the cases. I've gotten marginally better over the years; don't think there's any more 13" green monitors in the attic... Last time I talked someone into taking one of the 10meg drives was over 10 years ago when I ran a BBS. Two kids across town wanted to run doom. Turned out they had a dual 5½" 360K drives and no hard drive... ~~~~~~ Bait for spammers: root@localhost postmaster@localhost admin@localhost abuse@localhost ] ~~~~~~ Remove "spamless" to email me. |

All the voltages are relative to ground (the black wires) so you find a nice convenient ground location and connect the negative (black) of your meter to it (the black wire on a hard drive connector is a good spot and the probe tip usually just goes right into the open end). Then you just need to probe the wire in question with the meter positive lead. Your problem is getting to the 'backside' of the power connector when it's plugged in, which is where the paper clip comes in. You can try holding the paper clip onto the meter probe and touch the other end to the wire in question or, what I do is get a jumper wire with alligator clips on each end (radio shack has them) and clip one alligator onto the probe tip and the other to the paper clip. Then you use the paper clip as a probe (or any other small enough conductive object). Tonight I thought about just using black electrical tape and taping a paperclip to the probe to make it longer and thinner. You think that would work? Patty Alligator clip leads are cheap and easy to get at Radio Shack but taping it might work. Especially if you use the tape simply to keep it in place on the probe and then use that spot as a finger grip, meaning your fingers keep enough pressure on the two to make contact. |
