Can i run a gtx 1070 with a psu that has no 8pin connector, I just need to check if the graphic card is working or not.

No, the power connectors are not optional.

Easy. The 12v rail on your Power supply is the thing that gives the power. The 8-pin connect spreads the amps over the pins better than a 6-pin connector, but you can safely use a 6-pin to 8-pin adapter if needed.

Here is an adapter picked at random so you can see what to look for. Newegg etc also carry these: https://www.amazon.com/Cable-Matters-2-Pack-6-Pin-Adapter/dp/B01DV1Z32Y/ref=sr_1_1?ie=UTF8&qid=1511632307&sr=8-1&keywords=6-pin+to+8-pin+6%2B2+pci-e

Some video cards will even run with jsut the 6-pin plugged in. You can try this if you want, it won't hurt your card. It's like using a 4-pin MB CPU power cable in a 4/8 MB CPU power socket. (some cards check for connectivity on these pins, some don't.)
