That PSU as new has 5x single PCIe and 4 double PCIe cables.

Hey, yes the 4 double PCIe cables work fine and can power 2 GPUs.
Issue is with the 5x single PCie, do I need to purchase an adapter for those now?

Something like this : https://www.amazon.co.uk/Startech-Express-Power-Adapter-Cable/dp/B001TK3TJY or https://www.amazon.co.uk/dp/B07GJ6GB2B/ref=pe_3187911_185740111_TE_item

Nicehash keeps on crashing. I've used MSI Afterburner settings as follows :
Core 950 mV, Power limit -10%, Core Clock 1500 MHz, Mem 900 MHz, Fan Speed auto.

Miner runs for less than 5 minutes and stops few seconds later restarts...

What can should I do?

Remember to consider your fans power draw when calculating headroom on the PSU. I think 120mm fans run around .33a on avg - so maybe about 4w each? If you’re really pushing the limits of the PSU, your best bet is probably an open air rig w/ good spacing, and an external cooling solution if possible. Here’s my setup for example - the 8x64 rig is on the left. The spacing alone is generally enough to keep these reasonably cool (40-45c) even at 70-80f/21-27c ambient. The cabinet is more for noise suppression and dust control (this is my garage/workshop too!) but the airflow helps on those summer days when temps get up significantly higher. Many people just point a box fan at their rigs. (btw, the fans on the one rig aren’t necessary, but I didn’t bother removing them as I had the power headroom):

Hey, yes thanks for the heads up.
Both of my rigs are open air.

Niiice neat setup. Looks like it took you some time to plan everything out?
