Xion(SuperFlower OEM) 700W review by Wolf

[Travis]

the article

Well Wolf, I think you'd better throw that KAW away. The 85% it's telling you is totally B.S.

btw: that's a half-bridge design, not a double forward. Newer SF units are double forward w/ APFC.

well i know what 700w psu i won't be upgrading to in the future

it sure is colorful, though

The KAWs work properly with non PFC units. It's only certain PFC units that confuse them. This was not a PFC unit - I've checked both KAW's accuracy over and over and over (really... what else did you think I was doing in the two weeks it took to get the Thermaltake review up?). I have no reason to doubt them on this unit. Do you know what would happen if I retired them? No more reviews. For several months.

This review was a bit rushed due to the late posting of the Thermaltake - could be I missed something about the design. But the KAWs stay until I can afford something better. The Earthwatts 650 goes on the load tester today - we'll see what they say for that one.

Then I'll say that 85% efficiency number is really hard to believe...
You see, it's a traditional half-bridge design, no synchronous rectification to increase efficiency here, and even the rectifiers on secondary side are only cheap MOSPEC parts. I can't believe these can get 80% efficiency.

Spectre have seen another SF unit with older design (KWI 800W?) and you can ask him about its efficiency.

btw: I bought a Weibo PF1200 for ~480 RMB Yuan (about $70). I think it's quite fair and much more reliable than a KAW.

Well, it's not the KAW's. Not on a non PFC unit. What it could be is the SunMoon's watt calculation display itself, and that's a far bigger problem because when I do the calculations myself, they verify the SunMoon display. If it's the 268, it's losing its ability to accurately load units.

The 268 is getting a bit old now. Will be playing with it all day to see if I can at least figure out what's going on. Assuming the Earthwatts is reading funny too, that is.

BTW - if it indeed turns out to be the 268, a Weibo is the last thing the site needs.

[Travis]

does 268 display the current it measures or the current you set?

[Oklahoma Wolf]

Both. That is, it displays power output based on calculations from the current settings and voltage.

Efficiency results have been updated - the KAW was indeed off, to my profound annoyance. Found a way around it. Scoring has been updated as a result.

Whew, those temperature figures did not seem consistent with 85% efficiency.

I still think you dinged them pretty hard on "functionality" for ugly cables. The thing survived 100% load in the hot box with output in spec; that's worthy of a respectable score. (Shutting down cleanly is a pass, exploding or producing bad output is a fail. IMHO.)

You didn't have to unpack that thing and untangle those cables

Seriously, this was the only unit where I had to work at it for 15 minutes just to see what cable went where. They needed to put a few more zip ties on.
