I have a Silverstone Strider Essential Series ST60F-ES, it has 4 PCIE connectors, if each PCI connector has only 75W and each klondike uses 60W wont I be able to only use 1 per connector rather than split each connector? I thought originally each Klondike would consume 32W, but steamboat says the F16 uses 60W. Any advice on this? Will I be able to power 8 K16's with this power supply or only 4
One of those 4 connectors is a 6+2 pin, which is designed for 150W. Assuming they use the same gauge wiring on all the cables, it should be safe to pull 150W from each 6-pin's as well (both 6 and 8 pin connectors use only 3 positive wires). Though I suppose the PSU's internal connections could be poorly designed. The PSU can do a total of 500W on the single 12V rail, so I'd say you can probably run 8 K16's without problem.
Incorrect. The terminals are rated for 75W each (72Watt actual), this is why a 200W graphics card will have 2x6pin connectors for 150W plus the 75W from the PCI-e slot (~225W)
and 250W cards will have 8+6pin (the 8 pins (8 and 6+2) are rated for 150W, 6 pins are only 75W (72Watt actual)).
My point is that both 6-pin and 8-pin connectors use the same number of wires for the 12v line, so if they use the same quality wires for both 6-pin and 8-pin cables, then you can be sure the connector and cable can handle 150W on even the 6-pin connectors. As long as they tied all the 12v wires to the same mount point in the PSU, you're fine to pull 150W on the 6-pin's.
