I've dissolved my GPU miner and I have one power supply left - Thermaltake Smart M750W 80+ Bronze (modular).
Will it be suitable to power a few Bitburners XX or should I rather get rid of it?
That should work well. From the drawings, you can use Molex and PCI-e pin settings. That is all you need. Keep it. Or give it to me for ten bucks
