Default OCZ EliteXStream 1000 W Power Supply Review

There has been a new article posted.

Title: OCZ EliteXStream 1000 W Power Supply Review
URL: http://www.hardwaresecrets.com/article/648

Here is a snippet:
"OCZ EliteXStream 1000 W is one of the most affordable 1,000 W power supplies available in the market today. Its lower price point was achieved by carrying fewer features compared to other 1,000 W mode..."

Comments on this article are welcome.

So what's the difference between OP1000-E and EliteXStream 1000? Rectifier type of +12V output?

Yes, the rectifiers on the secondary are completely different, being the only difference between them. Take a look on the SilverStone review at JonnyGuru.com to compare:

The four power MOSFET transistors used for rectifying the +12 V output are FDP047AN08A0, which support a maximum current of up to 80 A at 144 C each
Quote:
The maximum theoretical current the +12 V line can deliver is given by the formula I / (1 - D) where D is the duty cycle used and I is the maximum current supported by the rectifying diode (which in this case is made by two 80 A transistors in parallel).

The math comes out right but the two transistors in parallel is confusing me. Instead of one diode per schottky rectifier its one mosfet per the two sets each in parallel???

Hello Merman,

Thanks as usual for posting your questions, this helps me improving my text.

Four transistors are used, two for the rectification part and two for the "free wheeling part". Thus for the math only two should be considered. This is the similar to what happen when diodes are used.

I am writting an update for the Anatomy tutorial, which will clarify this.

Cheers,
Gabriel.

The results from this review were updated today to reflect AC power and efficiency measured by our new precision power meter. The updated results did not affect our conclusions or recommendation about this power supply.
