The ball bearing fan is clearly audible under high loads, but it's not unusually loud for a 650W power supply . However, at 80% load and above, an electronic noise can be heard from a short distance. This may be a problem with our test sample, but it's still undesirable even if the other performance metrics are good.
The efficiency is as high, which is what we expected from the layout. This PSU is very close to achieving 80 Plus Silver certification, and it has no problem meeting the 80 Plus Bronze requirements. However, the efficiency at lower loads (5% and 10%) drops below 80%, which makes the PSU less suitable for low power systems or systems that idle under ~50W.
During low loads the current runs relatively flat trough the large PFC choke. The result is a power factor below 0.900--phase shifting is very high. Under full load 0.982 PF can be achieved.
The highlight of the HALE82 series is its voltage regulation, ripple, and noise results. These are simply put superb for a middle class product! We would like to see such results more often, though not surprisingly the performance comes with a cost.

...then details like cabling, warranty, customer support should be considered IMO.Alecthar - Thursday, January 26, 2012 - link
Agreed, though Corsair always loses out (for me at least) on their 650W TX models because they only allow for 2 PCI-E connectors (without adapters). It feels very much like a transparent move to force you up a tier to the 750W supply, or to a more expensive HX unit. It's all the more irritating given that XFX sells a nearly identical supply (same ODM, Seasonic, on the same platform from Seasonic) with the full 4 PCI-E connectors.As for being price competitive, given that the NZXT supplies are partially modular, they're more comparable to the TX series "M" semi-modular units, which are priced at a premium. The HALE82 is priced identically to the TX650M, and has a superior cable set, due to the inclusion of 2 more PCI-E connectors. I'd say that on the 650W model, NZXT has one of the more compelling "budget friendly" sem-modular options.

Exactly. While the Corsair TX V2, Hale82, and Seasonic M12II SS are all the same platform, they have different feature sets. The fact that the Hale82 is modular is a huge difference for many builders and many are willing to pay a premium for the easier cable management and cleaner look it provides..The other modular competitors (in terms of quality) at 650w are the Seasonic M12II SS, Enermax Modu82+, Corsair TX-M, and Corsair HX.and the Seasonic M12II SS, Enermax NAXN 82+, and Corsair TX-M at 750w. When you look at the field, the Hale82 comes in cheaper than all of them. To me, that makes it a clear winner.

This is like nails on a chalkboard to anyone doing anything with electronics:"Given the higher amperage of the A70GL model, this fan might reach higher speeds, e.g. 3000+ RPM."
It's 'current rating', not 'amperage'.
