As the question states. I know its not recommended and its stupid to do so. But im curious as to what will happen. Before I posted this i actually tried it already everything seems normal but what will happen in the long run (sorry for bad grammar)
Nvidia suggests that you should get a 400W power supply, however, more information can be found in the following thread: https://forums.tomshardware.com/threads/what-power-supply-should-i-get-for-the-gtx-960.2305080/
Edit
TL;DR: just make sure that you have a better power supply (this is coming from a person who uses a 350W power supply with an RX 570.)
You should also ensure that if you are buying one that they have a certification (bronze, silver, gold, platinum etc.)
I've been using it no problem, but people do recommend using a power supply rated for a higher wattage just in case.So I guess I can make this work until my connector arrives. Thanks for answering BTW
1 more quick question. How long have you been using 350w for RX 570? I just read that it requires a 500w minimun power supply
