Have you any concerns about upgrading your PSU?
Did you purchase a new or used PSU? Haswell launched in 2013, making it tricky to imagine this model still available unopened after that time. But it's possible. Still, capacitors have a limited lifespan, even if the PSU wasn't used for a long time, its condition would likely be affected by the age since its creation.

All items here are from Tier A. Rmx i mentioned earlier refers to Tier A.
ATX 3.0 compatible, multi/single-rail switchable refers to a switch that works with ATX 3.0 standards and allows changing between multiple or single rail configurations.
I agree with what @boju mentioned. A high-quality PSU from Tier A would be ideal for that configuration. A 750W model would be perfect, though a 650W unit would still suffice. They usually lose some power over time, and adding a bit more capacity won't hurt if you plan to use it under the 10-year warranty. Check out the information on ATX 3.0 here.
