I have a external GTX 1070 GPU "EXP GDC Expresscard beast" connected to a Lenovo T540p for render with Lumion, I power the GTX 1070 with a standard ATX PSU, all cables and components loose and exposed, so to carry it into a backpack with the laptop I want to enclose all the components into a case, and smaller the case, more suitable to carry around will be. SFX are ridiculously expensive in my country (USD$200 and more), if I try to import one, the mere shipment cost be too expensive to even consider it.
After looking around I came with the idea of get an iMac PSU to power the eGPU, I can get them NEW for cheap and shipment is very reasonable, adding the benefit of smaller size compared even to a SFX PSU, I'm planning to use a Apple iMac 21.5" 2009-2011 A1311 205W PSU 614-0444 661-5299 that is enought for the 180w the GTX 1070 needs, but if in the future I want to upgrade to a more power demanding GPU, the 205w can be not enought (besides, I'm sure not all the 205w can be delivered in the same 12v rail), so the question come here: can I get x2 PSU to feed a single GPU?
Thanks in advance for the advice and comentaries
