NEW modular PSU - Corsair HX620 review by jonnyguru.com
very good review on a seemingly very efficient and quiet modular PSU.
This looks very good.

Another Corsair review @ pcper.com.
What about the Adda fans? Are they acoustically similar to the Seasonic S-12's? I suppose the fan controller circuitry would be more important.
Corsair HX620W: Adda AD1212HB-A71GL 2,200rpm
Seasonic M12-500: Adda AD1212MB-A71GL 2,050rpm
Seasonic S12-500: Adda AD1212MB-A73GL 2,050rpm (3 features?)

So, what we've got here is likely a Seasonic-sourced modular-cable PSU with 80% efficiency at average loads (if Johnny is to be believed)? That sounds like the holy grail, to me. My NeoPower 480, while not the quietest or most efficient, did quite well and I loved the modular plugs, but alas, I was struck with the dreaded Asus board compatibility after an upgrade and had to sink to a Vantec a friend was willing to trade for. I had resigned myself to a Seasonic with non-modular cabling for my next PSU, but hark! Corsair may have done the necessary dances to align the planets in my favor.
Yeah, an almost all of the PSUs power can be delivered to 12V also (600 watts on the 620-model), which is really good (12v is the only thing that counts anyway, at least more or less). I think we can have a winner here.elfurbe wrote:So, what we've got here is likely a Seasonic-sourced modular-cable PSU with 80% efficiency at average loads (if Johnny is to be believed)?

Don't forget the Seasonic M12 is coming out this month, it's been speced with very similar efficiency to the original S12 with up to 85% efficiency and I assume it'll be comparably priced to the Corsairelfurbe wrote:So, what we've got here is likely a Seasonic-sourced modular-cable PSU with 80% efficiency at average loads (if Johnny is to be believed)?

Maybe? It be nice to see the M12 set up on the same test bench with the same settings to see how on par one is with the other.jonnyGURU wrote:Cooling is handled by a 120MM ADDA fan. But the impressive cooling characteristics of this power supply have more to do with the fan controller than it did the fan. I have to say that I never worked with a power supply that adjusted the fan RPM so precisely, to such subtle changes. When temperatures increased, the fan was quick to spin up, but when things cooled back down, the fan spun back down to a lower RPM. The fan never spun any faster than it needed too. I've gotten used to fan controllers that waited "too long" to spin the fan up, and then spun the fan up to full RPM leaving me with "all or nothing" fan noise.
