So, I bought this PC a while back (https://www.amazon.co.uk/Acer-Aspire-MC605-Intel%C2%AE-GeForce/dp/B00GKAPAW2) and i've been wanting to upgrade the GPU, but to do so i need a new PSU. I was thinking about buying a 300W Coolermaster PSU (http://www.coolermaster.com/powersupply/80-plus/mwe-bronze-450/) , but I'm not sure if it is compatible with my motherboard. Could you guys help me out? :3
