If you wish to build a pc using an M.S.I. motherboard and 2 M.S.I. GTX 970'S connected in scaling link interface to a 500 watt power supply,I would gladly enjoy watching a you tube video of the outcome after a month or so.
Trust me when I say you would be uploading that video using one of the asus/asrock/gigabyte machines you mention.
I didn't give him a 500 Watt PSU, i gave him a 650.
And i'd actually upload probably upload it from my xeon, msi mobo one.
You're kinda talking out of your butt if you think MSI is bad.
650 watts is 'Inadequate' generally for 2x 970's or 980's in SLI the same as any other sli or Xfire combo requires more than twice the spare gpu running watts of a single card (for start up load and other reasons)and preferably noted in the 12 volt amps rails output maximum.
A 650 watt unit is a really bad call for a single 970 or 980.
I'm not talking out of my Butt, I'm talking from a lot of years of interest and experience.
Do feel free to continue tho.
