Thermaltake TR2 QFan Series

Introduction
It has been sometime since we've seen a major brand like Thermaltake launch a new series of power supplies designed to address the needs of moderate users. We first saw Thermaltake TR2 QFan series at CES or CeBIT earlier this year, but the products haven't appeared in the retail market yet. We received test samples a few months ago, still with no sign of retail product, but Thermaltake assures us availability will occur during the next month.
The TR2 QFan series' claim to fame is limited to one area, and it's not even really a feature. What's so special? The series starts with a modest 300W unit, and ranges up to 500W in 50W increments. We will be looking at four of the units today -- everything except the top 500W model.
The QFan part of the name comes from the use of Thermaltake's patented fan design, which is supposed to decrease noise levels at higher fan speeds. Unfortunately, last time we looked the fan was just as noisy as any other fan design, but at least we can look forward to testing some decent power supplies that cater to users that don't need hundreds of watts of power. Finding good quality PSUs for this market has become increasingly difficult, and Thermaltake could step in to fill the void.
As you might expect, the differences between the various models are generally small. The 3.3V and 5V rails in the 300 and 350W unit are rated at 15A and 21A, respectively, while the 400W and 450W units are 15A and 24A. The 300W version comes with two 12V rails at 11A and 8A compared to the 350W version's 11A and 14A. The 400W and 450W also have different 12V ratings, with 17A on 12V1 and 14A (400W) and 16A (450W) on 12V2. All of this is in line with the higher output ratings, though there will also be some differences on internal components in order to support the higher wattages.

I like this, I'll have to try a few hundred!http://fakesteveballmer.blogspot.com">http://fakesteveballmer.blogspot.com

Can you ban this user's IP please? He keeps spamming over at Tom's Hardware also.strikeback03 - Friday, November 21, 2008 - link
If they want to keep spamming, they can just get a new IP.phreax9802 - Wednesday, November 19, 2008 - link
Only one 6-pin PEG connector? Come on..this is 2008! My old Enermax FMA II 460W has two of them..fic2 - Wednesday, November 19, 2008 - link
You measured that the secondary heat sink temp reached 80 degrees. How hard would it be for a user to replace the secondary with a larger heat sink? How hard would it be to find an appropriate heat sink for this? I looked on the internals pictures but couldn't find anything that I thought looked like a heat sink except maybe what looked like separator walls.ggathagan - Wednesday, November 19, 2008 - link
Regardless of how hard or easy it is, replacing the heatsink would void the warranty.It also misses the point: The manufacturer should be supplying the appropriate heatsink in a properly designed PSU. If they don't, why should I buy it?

Hallo Christoph,danke fuer deine ausfuehrlichen Reviews auch mal aus der Heimat ;-)
First, it would be nice to see a comparison in the 300-500W range. Next to that, please take a look at things like the picoPSU. Are they that much more efficient than normal psus and do they meet the demands for current htpc platforms (g45/780g/nv9300 with a small cpu)?

Thanks for the review. I'd like to see some more 350W and 450W PSUs.xaris106 - Wednesday, November 19, 2008 - link
I also think its great to review "low" wattage models. It's the biggest portion of the market, as you say in your articles, an I aggree. So thanks for reviewing this and i also hope you continue with this range of wattages. We all know that buying a high end high power model from a good brand, we will propably get a quality psu. But not so in the 300-500W range.What I would like to see is:
1) Step load tests: I would like to see how each psu handles load changes (eg a sudden 1A change). The voltage overshoots, settling times can give a lot more information about the quality of a psu.
In other words..transient response tests.
2)A review, maybe as reference of an as cheap as it gets no name psu, to see what we get more with our money spent on brand name psu.
Thanks.

What I would like to see is good quality sub 400 Watt modulair power supply's. These are (almost ?) impossible to find.It's a miss calculation from the manufactures that people will not pay more for these units. Many people who employ sub 400 watt units do this because they don't need more, and because it will have to fit into a smaller case. Then all those cables are just in the way, because they will not be used.
Further more (as suggested in to article) using high quality design and materials will give better power supply's. Sure they will cost more, but I'll gladly pay that if some manufacturer would build them.
And I don't think I'm alone in this. So please manufactures, start listning to your customers !!!!!
