Exernal power supply for fans

post #1 of 4
Thread Starter 
I have added fans to a steering wheel, 7 in total and have ordered this http://www.ebay.co.uk/itm/HDD-POWER-SUPPLY-AC-12V-5V-2A-FOR-HARD-DRIVE-MOLEX-UK-/320705061184
This looked great but sadly as it has a plastic part for pin 2 instead of a connection it just wont work for what i need, its small and light hence the reason iwent for it.

It has pins in 1,3,4
1 +12v
2 nothing ( plastic )
3 GND
4 +5v

So the 2amp psu will not power any of my fans as i need 1 and 2 for 12v, it wuill power my fans if i hook up to 1 and 3 but this is'nt very strong and is more like 5v, this is powering one fan to test so psu is'nt being overpowered, it cost £5

So i'm extremely stuck at the mo, i do'nt want a £20 psu attached to my racing simrig.

Fans are all hooked upto a 4 way fan splitter and they all work fine when using the 1 and 2 from the pc molex for 12v but this means pc side needs tobe opened and i dont like pc attached to metal cockpit just incase !

Any body any ideas

Heres a pic





Thankyou for any help you can give, any links ect must be from uk as im in England.

Thanks Geeboi,
Thanks for your your time, i binned that idea in favour of the small neat psu i got as it's clean, small and plug and play.

I'll have to wait for another idea as i'm looking for something like in the ebay link but with all its molex pins, if not i'll have todo a cheap psu conversion like in your link.

Had a tidy up as the psu i got meant today i could put teh side on teh pc case.

I've now just hooked up a molex to by the front drive bays, so i just pop one off now and pull the cable out.

The extension cable i'm using in speaker wire with a fan molex passthrough that i got with the fans at each end for quick releases lol
