Hi there,

I am looking to upgrade my computer from my GTX 550 ti to the 970 GTX

https://www.scan.co.uk/products/4gb-asus-gtx-970-strix-direct-cu-ii-oc-pcie-30-7010mhz-gddr5-gpu-1114mhz-boost-1253mhz-cores-1664-dp

I have a H67M-S/H67M-V/H67 motherboard so fitting the 970 should be fine. My main concern is my power supply which is currently a 500w PSU which is connected to my 550 using a 4 prong cable.

My technical pals have stated that i will be able to switch to a 6 prong cable with the GTX and therefore the 500W PSU will be sufficient.

Is this true or is their a risk that i may damage my computer?

Should i just buy a bigger PSU compatible with my motherboard for safe measure?

Cheers
