Depends on the PSU.
If it's a POS from decades ago then it'd probably be worth getting a cheap 80 plus replacement. More reliable, more efficient. Depending on load you can make the efficiency difference back in like a year or two.
But from a wattage perspective that would be fine, I ran a couple 7570s for doge mining on a 6800K with a Corsair CX430 PSU for a while.
