Power supply for AGP graphics - 20 pin vs 22 pin?

So, the power supply on my G4 Sawtooth (dual 450) is about half dead. I looked online, figured out which part I needed, and actually found one on Ebay. It was kinda easy. Then I took it to my Aunt's house (she's a tech) to install, and lo and behold... I have a 22 pin connector on my motherboard. The power supply (that everything online pointed to as the correct part) is a 20 pin. So of course, that isn't going to work.
I checked out everything again last night and all over the place I see that the Sawtooth has a 20 pin connector. Mine is 22, I swear... what in the ****??? Why the discrepancy? And does anyone need a 237W power supply?
Thanks,
Brooke

Gigabit G4, Digital Audio, Quicksilver and later Macs have a different power supply and motherboard that passes 28 Volts DC from the power supply to a connector for the ADC port graphics card. 28 VDC is passed to the Graphics card ADC port to power Apple's ADC monitors.)
If you are not using a ADC monitor, you might could cut off the connector from your existing supply & the purchased supply & connect the 22-pin connector to the purchased supply.
Here's some links of power supply sellers.

Not sure if the Apple Part #s are marked on your existing supply & purchased supply, but the links have the Apple Part#s for the various Mac models.

Power Supply for multiple Graphics Cards

I recently purchased an X1900 G5 Mac card. I now have my original (NVIDIA GEForce 6600LE) plus this new one. If I purchase yet another X1900, how do I get power to it? There is only one power jack on the mother board.
What are my options? Can my power supply support more caards? How do I connect them to the power supply? ATI pointed me to Apple support

Slot 1 (bottom) is the only slot designed for a high powered card. It is also the only 16 lane PCI-Express slot. The other slots have a power limit of 25 watts. Slot 3 is 8 lane, 2 and 4 are only 4 lane.
<http://developer.apple.com/documentation/Hardware/Conceptual/HWtechPCI/Articles/pci_implementation.html#//apple_ref/doc/uid/TP40003937-DontLinkElem entID64>
Put the 1900 in slot 1 (bottom), and the 6600 in slot 3. Even if there was enough power for a second 1900, it would not have the bus bandwidth because there is only one 16x slot.

plunked down WAY TOO MUCH on upgrades to Beige/Yosemite/MDD over the years, enough that "penny wise, pound foolish" I could have had Starbucks instead and gotten a new Mac.
Hello Hatter, you wrote:
I don't like to work on a system that pegs cpu @ 100%, I want it to run smooth and graceful. I don't need $5000 to get there. And you can have a LOT of fun upgrading Mac Pro and gradually add what you want to. And if you are adventurous... get yrs out of it in the process.
Software and OS upgrades have always helped market new hardware.
Number one: I don't come anywhere near 100 percent cpu usage at all when I am using my MDD. Though, I don't use Apple's complex software, once in a blue moon I will burn DVD's or CD's, but this is fast enough for me.
Secondly: You have owned an MDD far longer than I have. I just recently got this MDD which is a 2003 dual 1.25 - the VERY VERY last one before the G5 came out. I am happy with this machine as it is doing everything that my digital audio did, but faster. I don't need windows, though if emulation of TI-99/4A, MAME, and MESS become a problem, I might consider a MAC MINI alongside my MDD. I am in no way shape of form going to get rid of the G4. Plus, I have so much fun with the powerpc processor and its capabilities. I know, the bus speed is 167, but consider this. I came from a digital audio to this MDD and it only cost me 400 dollars on craigslist. The condition:
Brand spanking new! The owner told me he had never had any problems with it. No over heating problems, nothing! The only problem I had with it was a bad front panel board - but thats all in the past.
True, I personally wouldn't plunk down any more money as far as CPU upgrades go since the 1.8 and 1.6 duals don't offer L3 cache. If anything, I would get at low price a 1.42 board to put in this machine and make it dual 1.42, though 10 percent increase is really miniscule.
Which brings me to the next point - of course, upgrading a Beige, Yosemite was a waste of money because for what those systems were worth they ran on a G3 processor. But, we are talking about a dual 1.25/1.42 MDD, not G3.
I do like the Intel macs, though from what you heard about me spewing hatred towards them and the architecture, I was just plainly upset that day for no reason and decided to take it out on others. For that, I am deeply sorry. However, I plan to get a Mac intel mini to be networked alongside my MDD. I just realized that really for what I use my MAC for, I wouldn't need a mac pro or anything remotely expensive, given right now that I am just starting a new job in a few weeks.
Finally, I am still at odds of whether to upgrade to Leopard, since most of my software is all tiger oriented. I originally had Panther 2 years ago and I was hesitant about going to Tiger, but I did and I am glad I did since I see the performance it is giving me.
So, the MDD is not a bad machine and really isn't as slow as one would think - at least for what I use my system for. Explain to me why you are getting 100 percent cpu on yours?

Macbook power supply for MBP?

Is it possible to use MacBook nice and compact power supply for MBP?
Thanks

Actually they are the same size. I have a 85W adapater and it pops right into the power connector on my MacBook. I did not have the MBP adapater plugged into the wall socket though. The pin spacing and arrangement appear the same also.
The MP adapater lists the output as 16.5 VDC, the MBP lists two output voltages; 18.5 and 16.5 VDC.
I am NOT going to try and charge or power my MacBook from the MBP adapter, but I think it would be short sighted on Apple's part to use the same connector on both adapaters if using the wrong one could damage either the MB or MBP.

Power supply for MSI 645 Ultra mother board

I need to replace the power supply for a MSI 645 Ultra mother board. I've available a switching power supply Allied model DR-B500E, that doesn't have the -5V output (infact its 20 pin ATX power supply connector has no wire in pin 18).
Can I use this power supply with the MSI 645 Ultra?
Thanks in advance for any help.

Hi, here I am. Sorry for delay but I had some problems with the PC (as NTLDR missing).
However now is ok and I can confirm that it runs ok also with power supply without -5V output.
Thanks a lot for the support and best wishes for Christmas and new year.

Which power supply for k8n neo2 Platinum

I need to buy a new power supply for my computer. With the ATX12V v2.2 standard and ATX12V 2.01 and the "no -5v on new psu's" issue I'm at a loss as to what to look for. I have looked and cannot find what "standard" (is that even the correct term?) the k8n neo2 supports.
My main requirement is that the psu be 550-650 watts and have modular cables. I know someday I will have to upgrade my system to PCI-E and modern components, so I would like a PSU that would work now and in the future.
Could someone point me in the right direction?
Many thanks
system spec's
Motherboard- MSI K8N Neo2 Platinum
CPU- AMD Athlon 64 X2 Dual core 4800 939 socket
Memory-CORSAIR 2X1G Twinx2048
Video- ATI HIS 4670 1GB AGP
HD- Seagate 100 gb 7200 rpm
Drives CD-DVD and CD-RW
PSU- Ultra X Connect 500W ATX
Sound- Creative SB Audigy2 Gamer
OS- WinXP Home SP3 32 bit

Why do you need 550-650W or is that just because of future needs? I would suggest one of the Corsair +12V single rail modular PSU's if you insist on the modular design. Check newegg for what they have for modular in the Corsair lineup. I'm sure you're aware that their price is considerably higher than the non-modular. K8 MB's that needed -5V are the early ones that had Creative Sound Blaster onboard audio.
HX650
   * Was: $139.99
   * $109.99
   * After $10.00 Rebate
   * $10.18 Shipping
That's what it is now but if you don't need it in a big hurry you can probably wait a while and get for the same price but with free shipping.
Edit: Gee, Ultra with blown caps, I just happen to have a xPRO 800W that blew some caps, repaired it and started going bad again and then got my TX650 to replace it. Got it for $70 after rebate (which I haven't received yet) by waiting for the right price, rebate and free shipping. VX550 would have been good enough but at the time I got the TX650 at a lower price.

New Antec power supply for p7-1003w doesn't fit?!

I got a new power supply for my p7-1003w tower only to discover it would not fit. It was getting caught somehow so I looked and noticed it was not the supply itself but the black plastic bezel piece around the AC connection hole.
Has anyone else faced this? The original power supply doesn't have a bezel, but all the Antec supplys I see do.
If you've had this problem of the bezel beign too big what did you do bend your back plate? lol or is their a certian brand of supplys that don't have the big bezel around the connector hole.
Thanks!
Thomas

Hi,
Can you better describe the issue? See the below image:
I saw a posting like yours here on the forum some time ago but I can't say if an Antec PSU was being used. I typically recommend Corsair PSUs under 650 watts for the HP mid-tower chassis.

Because the XP597A3 (actually any of these product numbers; XP597AA, XP597A3, XP597AS) is a HP 2011x 20" LCD/LED widescreen monitor. The OP was looking for an A/C adapter power supply for the HP 2711x 27" LCD/LED widescreen monitor, which is product # XP600AA or XP600A3. The adapter power supply I linked to, is the correct part for the 2711x monitor.... that is why not those other parts.

Power Supply for Airport Extreme

Hi
Does anyone know where I can get a new power supply for my airport extreme in the UK? Mine has died, and I don't really want to buy a whole new base station just because of the external supply. (I know the actual unit is working through plugging in a power supply from my other base station)
I tried Apple, who weren't really any help.
Thanks in advance!
Tom.

Tom welcome to the discussions.
I would probably call the Apple number.

I am sure that they can point you in the right direction.
I am a little shocked that one of the Apple Retail stores can't offer you a Power Supply.
If all else fails, it sounds like you have tried an alternitve, if it works use it, until you can get a replacment.

How To Order New AC Power Supply for Satellite A350-20Q?

Hi,
I bought my Satelite A350-20Q 2 1/2 yeras ago, and when I turned on my laptop the screen was dim, the power supply was already plugged in but it did not make any change. How can order a replacement?
Thanks

According notebook specification AC power supply for your notebook has part number PA3290E-3AC3. I dont know where do you live but Googling around and using this part number as search term you will, I hope, find enough online stores where you can order new AC adapter.
You can also contact nearest Toshiba service provider and ask them to order it for you.
