Hello All
I did get a Asus GeForce GTX 1650 with the PC originally when i bought it back in July with the intention of purchasing a 3070 on release day.
I have now purchased and installed a be quiet! Straight Power 11 Platinum 750 Watt 80+ Platinum and the problem has gone away!
Unfortunately Overclockers where unwilling to replace or upgrade the PSU even when i asked for a price for a better PSU!
I was one of those people who saw the 1000w number and just assumed that would be good enough for the 3070 when i upgraded.
I am very surprised that Overclockers are still selling this brand given that i thought they where a highly rated system builder...
