Hi Deadsix,
I'm wondering if i could call on your knowledge once again.
Do you think it's possible to power a headless rig; 1x RX580 GPU, 1x Mobo/CPU/Ram/SSD, 1x Ver. 8s Riser by a Gold Standard 650W PSU. There are two local options for the 650W PSU in Superflower and Antec. Antec is about $30 cheaper than the Superflower.
Im thinking 250W for combined (SSD,Mobo,CPU,RAM) and 150-170W for GPU/Riser ? = 400-420W. Which is approx 64% of the 650W load of the PSU.
This should be more than ok, right ?
The other GPU's and risers are powered by a Server PSU.
I run several 4 x RX 570 rigs on 750W Gold PSU's, so 650w is more than enough for your need. Superflower makes some very good PSUs, and Antec is decent in the gold and above category so either of them will be suitable.
