ACBEL 614-0306 + PowerMac G5

[Nablabla]

Hello,
i'm new on this forum, and my english is (very) poor (sorry I'm french )

My PowerMac G5 have watercooling problems and i try to change the burned parts off the power supply (ACBEL 614-0306).

But some are so burned that i can't read the ref. (see here : http://forum.macbidouille.com/index....=post&id=37116)

Is anybody could help me to find those ref (D3-D5-W3-M1-C7 ...)

Thank you

and now ?

No, this way.

Now it's part of this forum and won't get lost if the other sites close or you delete it in the future.

godonr should have this info posted as soon as he sees it. I don't have this one in the shop (yet).

Welcome to the forums!

Thanks a lot, i'll wait for godonr's informations.

Re: ACBEL 614-0306 + PowerMac G5

Exactly what model G5 tower did this come from? This does not look like any I've seen. If it was a LiteOn PA-6601-1A I could help. Even the liquid-cooled machines I've had used a version of the LiteOn supply. Maybe someone else will recognize it! Sorry
Another question and a suggestion. The coolant is actually a pink anti-freeze. Were you able to stop the leak? If so, you can either wait for someone else who recognizes it to post or you can try to locate one for sale online.

Re: ACBEL 614-0306 + PowerMac G5

One more thought... go to macproonline.com. You will see your supply is rated at 600w and the equivalent of a PA-6601-1A LiteOn. Gives you another option if you decide to replace it!

Re: ACBEL 614-0306 + PowerMac G5

It's a powerMac G5 2,5GHz-DP (M9457LL/A ... A1047 - EMC1969C).

It seems that these computers could be equiped with a LiteOn or an acbel power supply ... I have an Acbel supply (614-0306-API2SF34).

Is it possible that these power suplly are the same ?

[godonr]

Re: ACBEL 614-0306 + PowerMac G5

See my above response (#9). They are both 600w supplies and fit your machine. I have not worked the ACBel version so I don't know the components. Sometimes the best thing to do is buy a "PARTS" only version of your supply to identify the parts you need. One place to check is buycheapr.com and search G5 power supply. Or, if you decide to purchase a working AC Bel, you'll have a spare you can fix.

Re: ACBEL 614-0306 + PowerMac G5

I have one coming. I'll get your parts info in about a week as it will be 5 days in transit.

P.S. - I got that you're French. But, are you in France or somewhere else? Please fill in your "Location" in your forum profile. Makes it much easier to direct you for parts and the like. -T

thank you Godonr, but at this time, i don't want to buy a new power supply. Too expensive for an old machine.
I just try to repair mine.

Great news, i'm impatient !

Yes, i'm in France, brittany (Bretagne) if you see ...
I'll take time to fill my profile !

Re: ACBEL 614-0306 + PowerMac G5

I have a similar power supply however its a 614-0306 API2FS34-291 However, it looks identical to the one your describing. It's made by AcBel. I don't have a blown cap, however the relay clicks on and off when it was plugged in. Could this just be the relay or is it a larger problem that would possibly cause this?

You actually have an identical supply. -> All your numbers are the same.
The API number is what determines the -real- model and design of the supply.
API = AcBel Polytech Inc.
2FS32 = Model & design of supply
291 = Customer ID number. In this case, Apple.

With that information, you should be able to provide the information Nablabla is looking for.
See his post #1 - D3-D5-W3-M1-C7

Mine shipped today, so Monday or Tuesday I'll have it to verify.

-------------

When does the relay click, exactly? When you push the button to start the computer? Or, just plugging it in, it clicks?

Yours is out of the machine and open, correct?

It's most likely -not- the relay.

Re: ACBEL 614-0306 + PowerMac G5

The values are as follows:

D3:4UF400 (Not Sure where begining and end is, they run together)
03408G

D5:1N4005
Y349

W3: (Blue Tantilum Cap.
Front Side:
BS415
250V~ TJ50(Then Backwards 'S')
X1Y2 42

Back Side:
CS222M

M1:
L7912CV
WCCFUQ414

C7: 220uF @ 25V

I Had to de-solder the diodes because I couldn't read all around, I believe the second line on the diodes, tantilum capacitor, and M1 are probably batch numbers. I've also included a picture of the diodes to show how they are oriented in case the silk screen on the PCB is charred as well. Here is the link to the file on badcaps, sorry 1st time doing this.

Toasty,
In response your question the relay clicks on and off when I push the button to power up the system. Currently the PSU is removed and open. I figured something would cause the protection relay from powering the system. I've repaired several of the iMac G5 power supplies so I'm a little proficient around these but this is a new problem and a new PSU for me.

Re: ACBEL 614-0306 + PowerMac G5

W3 - can be either an X cap or part of a Y cap setup. Its marking suggests it is suitable for either application and valued at 0.22uF. There are several more in the upper left of your photo, or lower left of the OP's photo.

From its position, it looks to be filtering high frequency EMI from the output of the PSU. Doubtful that it is bad unless it is damaged.

When used as an EMI and noise filter on the mains -
X caps go across (X) the mains and are usually a single cap.
Y's go from both sides of the mains to the chassis ground (forming a Y) and are found in pairs.

M1 - is a -12v regulator rated at 1.5A

D5 - is a regular 1A diode rated for 600v

D3 - is UF4004, a 1A, 400v, high speed switching diode rated for 50ns recovery time

C7 - I need the manufacturer and the series to get a match. Series can be a 2 or 3 letter code near the line with the temp and tolerance {usually 20% (M) }

All of these are a quick Google away, and DigiKey seemed to have a majority of them.

Re: ACBEL 614-0306 + PowerMac G5

Ltec is the manufacturer and the series is C(M) and it's temp is 105. I did'n't want to de-solder the cap but thats what I see so far down the side. I will be leaving for L.A. tomorrow and won't be back for a week to give more updates on this PSU. If you happen to have any suggestions for what would cause the relay to trip back and forth, I'm all ears. Normally I'm able to find the turn transistors, bloated caps, charred diodes, etc. But this PSU looks flawless, I have to say that the build quality on these is much betther than their iMac counterparts. Anyway hope this info helps.

Re: ACBEL 614-0306 + PowerMac G5

Thanks for your help. I don't find a C series from Ltec, they use at least 2 letters, but that's not a problem.

I'd recommend either a Panasonic FC or Nichicon PA/HE/PW, or UCC KY for the spot.

>>I have to say that the build quality on these is much betther than their iMac counterparts.<<

Plus there's room for the PSU parts to breathe!


@Nablabla - Now you should be able to repair the damage with this info.

Re: ACBEL 614-0306 + PowerMac G5

Remember this isn't for me, it's for Nablabla. My issue was the relay or more to the point some thing that causes to the protection relay to kick on and then off.
