Replacing a Wall Wart
Let me start by saying thanks in advance for your answers. I've read a fair bit on this subject, but I still feel like I don't understand enough to come to a conclusion on my own.
My question is this, I have a clock/radio that has a 6V DC input on the back, calling for 350mA, 2W. The original power supply was lost. I have two possible replacements, a 6V 500mA, and a 6v 200mA. Will either of these work safely, or should I buy a new wall wart to replace the missing unit?
Thank you -

Well, I tried getting voltage measurements, but it shuts down so quickly that it's very difficult. I think I'm just going to use the 650 with this mobo going forward. Even if I can figure out why this is happening, I don't see how that leads to a solution.
Hate to throw in the towel, but since I've got a working solution, I think I'll call it good. May revisit it later if I feel like it. Thank you for taking the time to assist me with this.Leave a comment:

Re: EA-500D boots one PC but not the other
I've tried it both fully installed (screwed in), and sitting outside the case, it makes no difference. I also pulled the mobo and put it back in, just in case something might have gotten loose or was causing a short or ground I could not see, but that did not change anything either. I'll check the voltages tomorrow and see if I can find anything.Leave a comment:

I've got a cheap multimeter, anything I could test?Leave a comment:

Re: EA-500D boots one PC but not the other
Yeah, I have the old setup running off the 650 right now, no problem at all. I've been swapping the 500 and the 650 in and out to test. Also, I pulled out the RAM and vid card. Even powering only the processor and the mobo, it still doesn't work.Leave a comment:

Re: EA-500D boots one PC but not the other
Indeed, checked those as well. No problem there either.Last edited by DOS-man; 04-27-2011, 10:14 PM.Leave a comment:

Re: EA-500D boots one PC but not the other
I should have indicated that I was referring to the connectors on the motherboard. I gave them another close examination just now and they look as good as new, no scorching or discoloration.
Good to know that I was correct about that amperage difference. Thank you for taking the time to reply.Leave a comment:

Re: EA-500D boots one PC but not the other
Nope, connectors look fine. Also, this board boots OK with my EA-650 v2, reviewed here. [url]http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story&reid=110[/url]
In notice that the EA-650 supplies 25 amps on the 5v and 3.5v rails, but the EA-500D Green supplies just 24 amps on those rails. That seems like too small a difference to be the source of the problem, but could that be it?Re: EA-500D boots one PC but not the... my EA-650 v2,Leave a comment:

Re: EA-500D boots one PC but not the other
Ok, so replacement arrived today. Plugged it into the motherboard, powering no other components, and... Same exact problem. The problem must be in the interaction between the board and the PSU. What could it be?Leave a comment:

Re: how to get rid of wifi mooches
I think the easiest way to upgrade the wireless connection on your eMac would be to get a wireless bridge. Probably the easiest way to get a bridge would be to get a router with DD-WRT and set it up to be used as a bridge.

I've never done that myself, but I've used the Linksys WGA54G and the Trendnet tew-647GA wireless bridge devices and I've found them to work well.Re: how to get rid of wifi mooches<b...e the wirelessLeave a comment:

The PSU in question is the EA-500D GreenLeave a comment:

Re: EA-500D boots one PC but not the other
Thanks for all the replies.
Because this unit is still very new, and I'm still just learning about PSU repair, I've decided to RMA the unit. I know it goes against the spirit of this board, but I've got to be realistic about my chances of executing a repair successfully, and I'd rather not learn to solder on something that's still under warranty if I have other options. I will post a followup when I get the replacement. I still have a feeling that maybe this board and this PSU just don't get along for some obscure reason....Leave a comment:

Re: EA-500D boots one PC but not the other
Thank you for replying,
I did some further testing, and it still does this if the only things it's powering are the CPU, mobo, and RAM. I even pulled the video card, but that didn't change anything.Leave a comment:

EA-500D boots one PC but not the other
Hello, and thank you for your help.
I have an Antec Earthwatts EA-500D that I recently tried swapping from my newer PC into an older one. However, I find that though it worked normally in the new PC, it will run for only 1 to 2 seconds in the old PC before it shuts down. The old PC works normally if I use my EA-650 PSU, but I'd rather use the EA-500D because I find it to be quieter overall.
