Thermaltake TR2 QFan Series

Cables and Connectors
Cable sleeving begins just beyond where the cable harnesses leave the front of the power supply. We tend to think it looks nicer if the sleeving begins inside the power supply casing, but it's not a huge issue and personal opinion plays a role. Also somewhat odd is that Thermaltake provides the same number of cables and connectors, with identical cable lengths on all of the TR2 power supplies. That means users get plenty of connectors on 300W model, but the 450W unit trimmings seem a bit spartan in comparison. We would have liked to see an 8-pin EPS 12V connector or an additional 6-pin PEG connector. Still, there are sufficient Molex and SATA connectors for all kinds of users.
The Fan
The fan is completely open on all sides. Thermaltake states that the patented design increases airflow and reduces noise, but it was difficult to confirm this in testing. The fan carries a Thermaltake mark, but it's manufactured by Everflow in China.

It's nice to see a PSU review that clears up the fact that you don't need an 800-1000w PSU to run a Q6600 with a 4850 or a 9800. After I ran an 1900xtx512 setup with 'only' a 550W PSU (those cards eat power!), I just couldn't understand why anyone needed anything more.I hope they come out soon; they look fantastic, and are a step back to reality, for most of us.
Great review on a promising product. I didn't see the plus-80 stickers anywhere though.. did I miss something?

1. More reviews of 500w and under, of course.2. A push for more modular units at all levels.
3. A corresponding push for standardization of the plugs on the modular PSUs.
Number 3 is especially important... because...
If the connectors at the PSU end were standard, the cable manufacturers would make cables of varying lengths, colors, etc., just as they make USB cables, SATA, cables, etc.
It's so nice to buy 8, 10 and 12 inch SATA cables with 90 degree connectors.
Wouldn't it be great if we could get proper lengths for our PSU cables?

Nice to see a review of small/moderate sized PSU's, and better yet to see you plan more of them in the future.The secondary heatsink temperature of these units look scary though, especially considering 80 degrees is very close to the 85 degree max heat rating of most inexpensive capacitors. I think I'll avoid these units for fear of exploding secondary capacitors... I'd like to see comparable results for the Seasonic 380W and 430W, the Corsair 450W and 550W units, and others in this power range - currently I'm using a Seasonic 430 and a Corsair 550, so I'd like to see how they perform relative to the competition.

SamXon are actually very high quality caps, they rate right up and sometimes surpass the best from Japan. I wouldn't be worried about them failing.yehuda - Friday, November 21, 2008 - link
How do they compare with the secondary OST caps that Seasonic puts in its cheaper lines nowadays? I've seen them in the EarthWatt series, the CX400W [1] and the Seasonic branded OEM SS-400ET [2]. I wonder if the two Taiwanese companies are equally decent or if one has a better track record than the other.[1] http://www.pc-experience.de/wbb2/thread.php?thread...">http://www.pc-experience.de/wbb2/thread.php?thread...

SamXon specs out with some of the best. There was some long term testing done with also at badcaps.net and they passed that test as well with flying colors.As far as OST; I've seen them fail when placed in critical locations such as CPU VRM but they seem to fine in secondary locations and probably fine for PSU use. I know Seasonic uses (or used) them in their OEM units and they are still used in the lower wattage PCP&C Silencers which is OEM'd by Seasonic and I've never seen a failed Seasonic or PCP&C unit (I've personally used both).

Thanks, I'll keep that in mind.Do you happen to have a link to the badcaps test? I occasionally visit their forum but I don't think I've come across it.
Operandi - Sunday, November 23, 2008 - link
The test is still going. Looks like it started in 2006, and all the caps are still holding their original ESR readings, except for the Samsung board that got killed by lighting. No surprise for the Rubycon and Panasonic but as you see the Samxon are right up there with them.I don't know how long they plan to run the test... if the Samxon are really as good as the Rubycon and Panasonics it could take awhile...

I'm curious how these picoPSU fair.http://www.mini-box.com/picoPSU-120-power-kit?sc=8...">http://www.mini-box.com/picoPSU-120-power-kit?sc=8...
They seem to be just DC-DC converters but the 12v source is rated at 5amp. I don't see how they can call it a 120w kit. Still, this thing seems extremely enticing should you only need 100w for maybe a small HTPC.
They also have a 200w version on there, but the 12v source question comes into play again. If I'm calculating this right, for 200w at 100% eff, you would need 16.7amp from a 12v source.

I second (third actually) the request for pico PSU reviews. We need a standard size PSU that can fit into iTX and mATX cases. I hope someone will create a standard size soon.
