Review on 🔌 StarTech.com 8 Pin EPS Power Extension Cable - 7.9 in Length - EPS12V (F) to EPS12V (M) - Yellow by Justin Hill

Luckily the PSU protected itself and shut down before anything fried on my motherboard! If you meet *a* resistance, make sure you're inserting the connector the right way round.
