Default Ten 1KW+ PSU's @ X-bit

http://www.xbitlabs.com/articles/oth...u-roundup.html

Review of 10 1KW+ PSU's, nice review, I was a little surprised with the bad review of the TT Tough Power 1.2KW, I thought it was quite a good CWT built PSU.

Conclusion.
Quote:
The 1010W FSP Epsilon is no good, either. My earlier tests indicated that this platform was only good for 400-500W models and not higher. The Epsilon 1010 proves the point: high voltage ripple, a noisy fan, and very unstable voltages. All of this makes it impossible for me to write a positive review of it.

So if you do want a 1000W power supply, you should consider the models from Antec and Enermax as well as from Floston and Ultra Products, but I want to note that none of them has proved to be better overall than the Cooler Master Real Power Pro (tested in my previous review) that boasted stable operation at a surprisingly low (for such a high wattage) level of noise.
Thoughts?

Was surprised as well!

Nevertheless, when it comes to PSU testing I put my faith in JonnyGuru first !

Wonder what he thinks about how Xbit tested these PSU's....

I like how Xbit uses a small lab oven to simulate a hot box environment. The biggest thing i don't like about there testing is the graphs they use to display the findings. They display allot of information its just hard to decipher what that information is saying. But then what do i know.

Well, I'm not sure I would "not recommend" the TT given the results.

It has higher ripple and noise, but it's still within spec.

And the voltages do droop if you crossload it as much as he did (the most he could crossload the unit and still keep the voltages within spec was 600W. The most I crossloaded it was 359.5W).

But these two points still remain:

The ripple and noise are still within spec and who's going to crossload the unit that much and especially do so with a total load of over 600W on the unit.

Obviously the other units, save the FSP of course, performed better so they would certainly be clear recommendations over the Thermaltake in Oleg's eyes, but I would not shun the Thermaltake either.

The weird thing is, Oleg's results differ significantly from other reviewers results.

Yeah - the Thermaltakes don't take to severe crossloading all that well. Probably partly because the 5V and 3.3V outputs are treated almost like afterthoughts in there... those two little daughterboards with the polymer caps are for those two outputs, while the 12V sections get all the real beefy stuff. It's like CWT designed it with 12V heavy systems in mind or something

Epsilon - no surprise there. FSP really needs to go back to the drawing board on those.

Not really.... just different loads.

Exactly. Which is why Oleg got different results. High +3.3 and/or +5V is simply unrealistic in today's PC's. I'm not buying this Thermaltake to throw in a Pentium III 900MHz Dell Optiplex with on board graphics.

yeah that surprised me too...I thought Silver Power was affiliated with Tagan or Maxpoint
