very good review on a seemingly very efficient and quiet modular PSU.

This looks very good.

I wonder who actually makes it (cos it sure ain't Corsair)...the heatsinks and Adda fan look very Seasonic-ish; the heatsinks are anodised black, as was theorised to improve heat dissipation here a while back.

Looks like a derivative of the M12 design...

I wonder if SPCR will review it.

We have an early production sample that we looked at but they want to send us a proper production sample.

That is great news. I will enjoy reading the review when it is online.

Any conclusions from the one you've already seen? Or have you agreed to wait until the real one arrives?

I notice that the manufacturer's code on the main transformer starts with VRL... just like the one in the Seasonic. Looks like a good sign...

Seasonic by all indications.

Agreed. The family resemblance is too strong.

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.

The big question is does it still have Seasonic's legendary fan controller circuitry, that is still unknown.

Should I get this Corsair PSU or the OCZ GameXstream 600w?

jaganath · Post by **jaganath** » Sat Aug 12, 2006 2:55 pm

Why not the Seasonic S12-600, if you really need 600W?

DontMakeMeEatU · Post by **DontMakeMeEatU** » Sat Aug 12, 2006 3:00 pm

It's a bit too expensive.

The corsair sells for $169.

The S12-600 can be found from ~$140.

Where did you get the pricing for the Corsair? I thought it wasn't out yet

And I'm trying to get everything from newegg so the Seasonic is $160

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 Corsair

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.

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.

The 520W version has 40A on the +12V rails. More than the S12-600.

Any news on when you will have your final review?

Anybody's thoughts on the 520w model?

Looks good....

jonnyguru.com covered the 520W version, too.
