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.

Thanks!!
