You said the previous two units you tested shut down after you ran them at 450W. Did they both have the same switchers (FQAF11N90C)?

I know one definitely did. I can't remember what the other one had.

Because c_hegge apparently forgot to remove the original review, I've just done it for him. (He has promoted me to being an editor just yesterday.)
Information is far more fragile than the HDDs it's stored on. Being an afterthought is no excuse for a bad product.

Any idea what the extra optocoupler is for? As I understand it, one optocoupler is for UC3843, one for Viper22A, and one for TPS3514. Also, 2SK2611 is rated for an ON resistance of 1.4 ohms max and 1.1 typical, and FQAF11N90C 1.1 ohms max and 0.91 ohms typical. That works out to a 27% difference, not a 32% difference.

Probably to enable/disable the UC3843.

Also, 2SK2611 is rated for an ON resistance of 1.4 ohms max and 1.1 typical, and FQAF11N90C 1.1 ohms max and 0.91 ohms typical. That works out to a 27% difference, not a 32% difference.

:huh: It says 1.2Ω typical in the datasheet I have for the 2SK2611.

So the typical value is indeed 32% higher for the 2SK2611 than the FQAF11N90C, with the maximum value 27% higher. (If it was 1.1Ω typical for the 2SK2611, like you said, that would be 21% higher than the FQAF11N90C's 0.91Ω.)

The alldatasheet says 1.1 ohm http://pdf1.alldatasheet.com/datasheet- ... asheet.pdf

Datasheet catalog too http://pdf.datasheetcatalog.com/datashe ... a/3010.pdf

But I always state maximum value (worst case scenario) as the nominal, that typical is more like marketing…average fuel consumption of car (in unrealistic scenario) or SDP (was it this?) vs. TDP for intel CPUs are another great examples of such BS.

The version I have is more recent (2010/01/29) than the one DatasheetCatalog has (2002/06/27). So what prompted the change (none of the other specifications are affected)? (AllDataSheet is "temporarily unavailable", apparently.)

BTW: I know that TDP means "Thermal Design Power", but what's SDP?

One of the pictures in the review shows the datecode of the 2SK2611 in the Hipro to be the 5th week of 2007... and the datasheet for 2SK2611 dated September 29th, 2009 shows 1.1 ohms:

Scenario Design Power and as long as they state that exists just for mobile CPUs since 2014, they have been using it at least from Core 2 era even though often they actually labeled that as the TDP. So sometimes maximum consumption may be much higher than stated TDP (I think some of the 1366 and 2011 CPUs are an example). Intel always claimed it is "different metrics" (using average etc.) than AMD uses while AMD has been using the same TDP metrics the whole time (absolute maximum), just Intel has been playing games too look better.
