Do you recall seeing them list the A3 revision on their site? Because the only ones I see are A1's and A2's.Putz wrote:FrontierPC.com is great, and located in Vancouver. I bought a Tornado A3 from them a month or two ago (online order), and the service was quite good. I also visited the store while I was on vacation in the area in August, and it seems like a decent place.

That +5V barely creeps under 5%! In the review it's claimed that the rev A3 are better than 2% in every case. Do I have a defective sample or are the sensors on the mobo not reliable? The mobo is MSI K7D Master-L
I did an upgrade myself about a week and a half ago and got the ss460
to replace my stock Antec smartpower 350. There does seem to be a low
3.3 rail issue with these whether real or incorrect software reading?, I e-mailed Seasonic but haven't received a reply yet. I must say I'm happy
with it so far. I've got my new mobile 2600 running at 2460 [email protected] v
and it's cool and quiet. Here's a thread I started at Abit a short time ago
that pertains to this a little. I will also add that my previous Antec Smartpower 350 (3.3)volt rail showed better on same setup only down to
3.24 or 3.26 usually. The Seasonic will drop to 3.18 during Prime 95 at times..

Here's a few pics I just shot of my rig and finished install of ss460 using included Dr cable..
Anitec on Kingsway also has it.slimeballzz wrote:Do you recall seeing them list the A3 revision on their site?

I purchased the Super Silencer 350 and have since noticed that the output on each rail is the same amperage for the the entire PSU series including the Super Tornado, with the exception of the 12V rail. How is it possible to go from 300W to 350W by increasing the 12V rail by 1 amp? Shouldn't that be closer to a 12W increase? This is not the case for other manufacturers like Antec and Enermax. Any thoughts?
For swedes: Just bought a 300W from www.jmedata.se and it turned out to be an A3! Tried www.overclockers.se and shg.biz before that with no luck...
I suppose they should be the same hardware wise, what the OEM version lack is basically the cable management kit I think.
There are other places to find Seasonic PSUs in Sweden though they are most likely not revA3: search result at buggy.

There's a Seasonic s12 600 watt review at pc perspective. Anyway, concerning my last post about a possible low 3.3 volt issue, this reviewer
put forth an interesting hypothesis.. here's a snippet and then the link to
the page..
As you can see, all of the DC outputs were held within the ATX specification while operating under a 263 watt combined load when measured at the 24-pin power connector. However, with the 20-pin adapter cable inserted, the primary voltages dropped slightly due to the added resistance of the connector. This was particularly noticeable on the 3.3V rail as all the 3.3V power (~10 Amps) during testing flows thru this connector.
The voltage drops caused by the added connector illustrates how important maintaining good connections with minimal resistance are. Even very small resistances can cause noticeable voltage drops due to the high current load. This is why I am not personally a big fan of power supplies that incorporate removable cables or require the use of adapter cables.
R = E/I = 0.1 volt / 10 amps = 0.01 ohms
Applying Ohm’s Law, we can confirm that a very small resistance can cause a measurable drop in voltage. In the example above, if a connector has 0.01 ohms resistance and 10 amps of current flow thru the connector, the resulting voltage drop will be 0.1 volts.

For swedes: A friend of mine got in touch with www.jmedata.se before buying a 300W OEM and a 400W retail and got them to CONFIRM that they were indeed A3 BEFORE shipping.

Tamas: I contacted www.wpcport.de and asked them how much the Super Silencer 460 would cost and they told me they sell it for €169 !!
That's way too much in my opinion (especially when you know they sell the same model for 100$ in other country's...), so I'm gonna try to find another shop in europe or look for another PSU.

Thanks your answer. €169 is very expensive, in this case I will wait till summer because a shop promised me that they'll get Sesonic S12 power supplies.DragonOptical wrote:Tamas: I contacted www.wpcport.de and asked them how much the Super Silencer 460 would cost and they told me they sell it for €169 !!

If I couldn't find Seasonic dealer with good prices, I would buy Nexus NX-4090 or a new improved (80% efficiency) 350W version of Nexus that will be released soon.
Now a Nexus NX-4090 costs about €112 in a Hungarian shop.
Well I don't know if you already have another PSU but this german shop also sells Seasonic PSUs:
