Hi all,
After much deliberation over whether to buy a PSU or convert a server PSU to power my multi charger, I bought an HP DPS-600PB series ESP135 PSU, it is rated at 575W, or 47A at 12V. It is the one used in ProLiant DL380 G4 Rack Servers. I bought it off fleabay for £16(free p&p
) and conversion took about an hour. Would have been a lot shorter, had I noticed the tip of my gas soldering iron was loose 
. The most difficult bit was bridging the gap between the two output connectors, but apart from that, it was a doddle. I followed these instructions https://sites.google.com/site/tjingu...projects/HP47A, and was amazed at how easy it was to do.
No taking things apart, although you can get a neater finish with banana plugs drilled into the unit if you do. It is currently charging 4x 5000mAh packs quite happily and the case is cool to the touch.
I have to say, it isn't as quiet as my 200W fusion PSU, but compared to the Dell PSU's, that sound like an army of vacuum cleaners(so I've read), it isn't too bad.
All that's left to do now, is buy some 100mm heatshrink and I'll have a neat, slim line, yet powerful PSU, for a fraction of the price of a dedicated PSU. If you are humming and haaing like I was, and electronics not your strong point, like mine isn't, worry no more, it must be easy if I managed it.
Cheers,

. I made the bridging cables long enough to slide up inside the heatshrink I put over the 2 output cables. Made it look mildly more professional hahaha!!
