For my Zotac GeForce 9300 mainboard, I need a PSU with an 8-pin motherboard connector. This PSU is hard to find and expensive. An adapter is available to combine with a 4-pin mobo connector to make it an 8-pin. Does anyone have experience with these $5 adapters, or would it be better to buy a PSU with the 8-pin mobo connector?

Re: Zotac mainboard needs PSU with 8-pin mobo connector
For the most part you can just plug the 4-pin into the 8 and it'll work fine, just don't expect overclocking and such to be stable. I've never known a board that won't work using a 4 in the 8. -
Re: Zotac mainboard needs PSU with 8-pin mobo connector
The 4-pin mobo connector only fits in slots 5 to 8. Is that normal? IIRC, the 4-pin PSU did not work, but an 8-pin PSU did work. Unfortunately, I only borrowed the 8-pin PSU, and lost the opportunity to buy it.
I just powered it up with the 4-pin in slots 5 to 8. I got a display but the fan did not work. The CPU fan gets power from a connection on the mobo.Last edited by binsonk; 09-02-2015, 08:14 PM.Comment

Re: Zotac mainboard needs PSU with 8-pin mobo connector
I had an Intel D975XBX2 which would refuse to POST if you used a 4-pin CPU connector. The majority of motherboards, though, will work fine with only 4 pins connected.
The thing is, though, virtually all new PSUs have an 8 pin EPS12V CPU connector, so I don't know what you meant by hard to find and expensive.
see http://www.newegg.com/Product/Produc...82E16817151148. Dirt cheap, reasonable quality and it has the connector.Last edited by c_hegge; 09-02-2015, 08:20 PM.I love putting bad caps and flat batteries in fire and watching them explode!!

Thanks for the link, c_hegge. It's sort of the point of this query to find out about the even cheaper adapter.Comment

Re: Zotac mainboard needs PSU with 8-pin mobo connector
It would probably work too, but I prefer to avoid using adapters where possible in favour of a PSU which has all of the required connectorsI love putting bad caps and flat batteries in fire and watching them explode!!

Re: Zotac mainboard needs PSU with 8-pin mobo connector
it's possible that the 12v pins on the gfx card are not all linked and some are directly driving different parts of the card.
that would be a poor design, but it sounds like what's happening.Comment

Re: Zotac mainboard needs PSU with 8-pin mobo connector
Depends on the CPU. Something such as an E6600 does not need an 8-pin connector to power it, regardless of what motherboard it's installed in. With an OC'd 125W CPU, though (Core 2 Extreme for instance), then yes, you would want to use an 8-pin connector.I love putting bad caps and flat batteries in fire and watching them explode!!

Re: Zotac mainboard needs PSU with 8-pin mobo connector
Oh my, I wasn't satisfied with the cooler and fan on it, so I swapped in a stock Intel cooler, and now the CPU fan works with the 4-pin mobo connector in slots 5 to 8 (?). I think I can make a box now.Last edited by binsonk; 09-02-2015, 09:44 PM.Comment

Re: Zotac mainboard needs PSU with 8-pin mobo connector
The 8 pin converter works fine just remember it is sucking more current from a single power line on the psu so dont overload your psu.You are only too old when you say you are too old!!!Comment

I got a new toy. I don't have many units with specs this good.
Zotac mainboard
2.6 GHz Dual Core
nVidia display
1 GB DDR2 / 800 MHz FSB , 128 MB onboard video (VGA)

you should double the ram - other than hat the specs look good.

Re: Zotac mainboard needs PSU with 8-pin mobo connector
If I spend any money on this unit, first priority will be the correct PSU with 8-pin mobo connector. I don't know many distros of Linux that would falter with 1 gig of DDR2.Comment

Re: Zotac mainboard needs PSU with 8-pin mobo connector
I dropped by the local computer repair shop to look for a 4-to-8 pin adapter. The man said of the 8-pin mobo connector that the other/extra 4 pins are to power a graphics card, implying that the motherboard is adequately powered by the 4-pin connector.Last edited by binsonk; 09-03-2015, 02:25 PM.Comment

Hi All -
I had replaced my ASUS 4090 Strix cooler with a waterblock and put the stock cooler on the shelf. Was moving it and snagged my sweater on the connector and pulled the wires out of the pins on the RGB connector. I tried to get them back on but its too small so I opened the stamped pins and tried to solder but its not a good repair and the wire broke on reinstallation.
Looking to replace the connector on the cable side and get pins to crimp onto a new cable. Bought random JST and such but nothing is correct. Can anyone help identify the connector and possibly matching... -
Hello i got a card with 12V short, found an IC blown Q510, remove it short persist, found that the short is on 12V GPU, remove all the Mosfets and the short still there, i inject 1.5V to the line and i got 1A of consumption, nothing getting warm, this could be the GPU itself?... -
Hello guys,
im actually trying to wake up a non powering up gpu, model RX580 Pulse 8gb. I have a multimeter and 3 lab PSU. I mention 3 lab psu because i don't have mobo so here is the situation. I followed step by step the video from here (https://www.youtube.com/watch?v=supu7YeNTfw), he does another one about the 1.8V regulator possibly guilty, In both scenario, as me, No vcore voltage but no short anywhere. But in his case he s plugging the gpu to his mobo and the 8pin connector as well when for me, for the moment as i don't own mobo, i just inject voltage from the 12V rail from...11-11-2022, 10:51 AM -
Hi guys,
i have a damaged keyboard connector on my older Toshiba Satellite M50-A laptop. I know there is LA-A481P motherboard. In attachment pictures there is a real looking connector and i also found a schematic to the connector. But i need help with finding a real electronic part to replace the damaged connector. e.g. on aliexpress (or different page).
It is 34pin connector and the length from pin n.1 to pin n.34 is 26mm. So it means a pitch length is 0.764 mm. I have seen connectors with 0.5mm , 0.7mm , 0.8mm and 1mm pitch length. But not with 0.75. Is it some special custom connector... -
Hi everyone
I have a 70mai Dash Cam A510 which failed after about 3 months of being installed in my car, likely due to heat, i got it from aliexpress so no point in trying to return it for warranty (and shipping it back would cost me almost the same as a new one from ali)
The camera would boot loop showing 70mai logo on the screen, sometimes it would boot fine then the live view would freeze or display purple lines
I already took it apart, and found out that the camera boots fine if i unplug the camera module from the main PCB, sometimes "playing" with the connector...
