The 1300W G+ PSU has 6 VGA (PCIE) inputs. I need 2 more VGA inputs. 
  1. Is it OK to use 2x FEMALE 8pin to MALE 8pin cable? If I get 2 of these types of cables, I wouldn't need additional VGA inputs. 
  2. Where would one find these types of cables? My googling has been lacking, but I have a feeling the lack of results may be for good reason.
For specifics, I'm trying to connect an additional GPU/GPU riser. The additional GPU has TDP of 220 W, and the GPU riser would be around 75W I think. I am currently drawing 450W from the entire setup (MOBO, CPU, etc.).

    That psu has one massive 12V rail. (108.3A)
    Using the sata1 to 4 connectors with adapters will work

    Usually those kinds of cables come from china, so it means a decent wait time... try the likes of Aliexpress?

    I really would stay away from using (especially) Sata power cables to 6/8 pin adapters for your PCIe. There's a risk of burning the sata cables and catching on fire. Molex (22Amps) technically has a higher amperage compared to Sata (13.5Amps). So it's better to use Molex to 6/8pin PCIe adapters if possible at all. And if you must need to use more than 1 molex, it's recommended to use a separate Molex cable for your 2nd Molex input. Using 2x Molex plugs from the same cable/line will just be the same as plugging in 1 Molex in this case.

    While it MAY work, it MAY cause fire.

    Don't take that risk for some crypto or whatever.
     
    The G+ is an older model as well. It is wiser to just get a new PSU, even though they are expensive.
