This is just a warning to let people know there is an issue with at least 2 different models of MSI mobos and coolermaster power supplies. Basically they won't boot I have an current RMA with scan and dabs of a coolermaster M700 pro psu where the fans and leds will spin up for a split second then nothing. My old akasa psu works and so does a brand new corsair hx620. I have had a nightmare new build over the xmas period meaning i have had to end up purchasing 3 power supplies. Check neweggs site there are several other reports of this and on coolermasters forums. Dabs have settled my RMA in super quick fashion with a refund. Scan haven't as yet but I hope there are no problems though.
