Default Thermaltake Toughpower 800 W (W0296RU) Power Supply Review

There has been a new article posted.

Title: Thermaltake Toughpower 800 W (W0296RU) Power Supply Review
URL: http://www.hardwaresecrets.com/article/823

Here is a snippet:
"Toughpower power supply series is around for a while now and Thermaltake has just added two new models to this series: 700 W (W0295RU) and 800 W (W0296RU). These two models are 80Plus Silver certified..."

Comments on this article are welcome.

Why are there no comments on the fact that the OPC kicks in well before the rated 12V current limits are reached? The PSU is thus unable to deliver the rated (12V) power!

According to your tests:
* 12V1 shuts off at 29A when it should be able to deliver 30A.
* 12V1 and 12V2 are supposed to deliver up to 66A together, but can't deliver more than 54A (82% of rating).

Due to the cable distribution you really need power-hungry graphics to make use of the all available power.

Cheers

Are the schottky rectifiers not placed in parallel with the Mosfet to reduce voltage drop (=power loss) when synchronous mosfets are off? Or even maybe to prevent the internal mosfet diode to conduct (slow/EMC/losses)?

Yes, they are connected in parallel to the MOSFETs, this is described on the text:

Quote:
using two SSC53L Schottky diodes to prevent cross-conduction (this design is called “zero voltage switching” or “lossless switching”). These diodes are soldered directly to the printed circuit board and thus not present on the secondary heatsink.
Cheers,
Gabriel.
