Modern PSUs will have better caps, electronics, etc and will be more power efficient - if that's not an oxymoron.
I would suggest check power-consumption first with a Kill-Watt device, most PSUs are way to big and are most efficient when loaded at > 75% of max capacity. HD’s don’t use that much power.
