Hey everyone, I just picked up a HD5870 and was going to add it to my current rig... well this 5870 was asking a little much from the PSU and it cant power it and the other 3 GPU's. The one I have powered the 3 5850's great, but this 5870 puts it over its limit
So, I am asking for your advice on a good PSU.
Heres my setup:
Sempron 140 proc
2.5" laptop 5400 sata drive
3 Sapphire HD5850 (would like to overclock them to around 900 core, 300 ram)
1 gigabyte HD5870 (would like to overclock it as well to somewhere around 950 core, 350 ram)
I also have an ePower 420 watt "juice box" that supplies power to GPU's but I dont think I trust it with more than 1 GPU. Maybe powering 2 of the 5850's it might be ok.
My case has 2 120mm fans in it.
Please give me some good suggestions to power this beast, and allow me to overclock my GPU's for maximum mining effeciency.
Thanks in advance!
