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
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.

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!!
No wonder it doesn't work! You installed the jumper wires backwards

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!!

Otherwise, especially with heavy use, you'll overload the adapter's connector and the 4 wires trying to carry the current of 8.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.

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.
