Mining with r9 280x

lomi2001

Hi, i’m getting for an r9 280x and i’ve already got a psu of 450 with 80+ silver’s certification (lepa).

Will it be enough to power that cpnfiguration : itel i5 (tdp : 95w) , 2hdds, and 1 ssd and msi h81m motherboard ?

And what is the hash rate of the r9 280x graphical card ?

Thanks you in advance for your answer,

Yep that should be fine, might be a little close but probably not. You should be around the 500KH/s range

Just a note, you can always use an (additional) separate power supply for the GPU card. Cross 13 / 14 to keep it on.

Using a “GPU external power”, means a low specification board and PSU can be used for a mining PC.

A low power “used” PSU, just to power the GPU. I extracted a few from some old PCs from Freecycle… Neoscrypt can not drain the GPU melting currents of high Intensity possible with Scrypt, because of the memory requirement, so even a old 350 Watt worked fine.

Use a power plug / hall effect clamp (from power company), to accurately assess how much the PC and GPU power are taking.
