I'm using server PSU's. Dell 1570W one's. They power 3 ants... (2 oc'ed and 1 normal freq).... Can get them to work all 3 oc'ed... But it will take me some time... As the PSU has 5 Output pins which have a max of 312W per pin. I would need to connect the 5 pins in order to get the full 1570W out of it..without worrying that I will ruin my PSU. (Happened to some 930W one's I had...I wasn't aware that they had a max W on the output pins).

I didn't think to use Server PSU's. Yes, the price per watt is remarkably cheaper than your typical desktop PSU. Looking at pictures, I can't tell how you would be able to use this. Is there a breakout cable that attaches to the only port I can see?

On this forum you'll find loads of different PSU conversions.... Just one example of many:

You'll need to jumper a few pins together... but it's really REALLY easy.
Then you can opt for another jumper (of 2 pins) and that will lower the fan speed.

The PSU I have....it sounds like a boeing 747 on the runway... so that jumper saves me a load of headache!

Installing a couple of 1k resistors will reduce fan speed depending on load.

I thought thiers was a little messy thou, so I made up some resistor banks that just plug on.

cool... I didn't give that a go...as I didn't have resistors lying around... and I'm not that technical... Have some junk electrical equipment.. Might remove a resistor and try it...just for fun.

The descriptions I read were talking about an option of multiple resistors (each different strenght) and I was reading that...scratching my head.. thinking...Nah why be difficult...jumper it and should be enough

Found another link....this thread has a lot of PSU types and there pin-out diagrams (to know which pins to jumper in order for the PSU to turn on, etc)

I think this is way better then computer PSU's... The only draw back...is the wiring fron the PSU to the ant. With a computer PSU you just plug in the PCI connectors and your done.. With the server PSU I'm busy for a while with all power cables.. I used some extra (junk) power leads I had.

I ordered a corsair 1000w PSU on amazon for 130 GBP and some guys on this forum told me I could only power 2 ants.. I thought you know for 20GBP a 930W Dell PSU...just give it a try..and if jumpering is too difficult or I mess it all up...then at least I tried and I only loose 20GBP.
It worked and was really easy...so I canceled the order on amazon saving me some money...At the moment I paid 132GBP for 3x 1570W PSU's able to power 9 ants
