Your link is dead, so i can't hear the noise and tell if it's the coil whine or fan bearing noise. Either way, while OCZ makes fairly good SSDs, that specific PSU is low quality unit using HEC platform.
For better PSU build quality, i suggest you replace your PSU with proper power plant. Anything from Seasonic will do just fine, in 500W range. E.g M12II-520 EVO or G-550. Both PSUs are good quality units.
All my 3 PCs: Skylake, Haswell and AMD are also powered by Seasonic. Full specs with pics in my sig.
