I can't afford a psu upgrade but I'll look out for some local deals. Secondly, the psu is old but it has seen little use from before 2018 as it was sitting in my brothers old pc for like 5 years, and he only used it for 2. And the person he bought it off probably didn't give him the extra unused psu cables. I think the psu has some life left, so I would like to try the dual 6 pin to 8 pin method. Sadly, I can't find any of these adaptors online. I saw 1 on ebay but it is unbranded. If anyone knows where to get a branded one, or this power supply's specific modular pcie cables, that would be really nice. (Plus the power usage is from msi afterburner and hwinfo during the unigine heaven benchmark) (and I am from Britain so my currency is pounds)
