If I get a 5850 and put it in the same rig as my 6990, would my 1kw PSU support them both mining? I know with the setup I have the 6990 the max load would be around 800W give or take. If the 5850 uses 150w at full, it'd be around 950w load on my PSU which should work but is it safe?
O.o
800W for a single 6990 system? What the hell have you got, a cuisinard? /spaceballs
Seriously though what do you have in there? A single 6990 has a TDP ~400W - you should be able to run
two in a 1KW envelope.
I've tried multiple PSU calculators and they all come out to around 700-800W with 90-100% load so I just assumed :p
I have a Core i7 Xeon overclocked to 4.5ghz, 6GB of RAM, 4x WD Green 1TBs, 2x SSDs, a PCI sound card, a USB 3.0 PCI-E host, about 5 USB ports in use, 8x 120mm fans, a water pump, and 3x CCFLs.
My old 1kw PSU died a month back while bitmining. I surely believe it was old age as it was a 4-5 year old Silverstone PSU, but I could never be quite sure due to the odd symptoms it was giving. So I just want to be safe before throwing another video card in :p
