Fortron FX-760E question

[Makalu]

As near as I can tell the FX-760E is the same as a FX-700GLN except for using the peak rating for total watts and a "gamers edition" sticker for your case. All the other wattage and amperage ratings are the same. I was wondering if anyone knows if maybe the cooling fan or heatsinks or control is different?

Rated at 50A combined 12v, 200mV ripple, 760W @ 25 degrees. Enough already with the Epsilon design FSP!!!

I doubt anything of significance is different from the 700W.

[Makalu]

yeah everything of consequence in the two pdf's are the same...i wish they'd give the combined 12v rating in the 600w version pdf instead of having to rely on the questionable label format...ah well about 50 bucks more lol and the one review for the "Extended" unit at newegg says "you get what you pay for" hehe

[Oklahoma Wolf]

The 600W is 44A IIRC... you get it by calculating it from their full load specs in the PDF.

That FX-760E has been out since Nov. ;)
Here is the updated FX700-GLN-E and the Blue Storm II 500W

Ah thank you, that makes sense...I wasn't sure what they were trying to rate in that chart, and obviously didn't take the time to examine it either doh. I guess the 760E is rated at 51.6A combined then even though it says 50A elsewhere.

200mV ripple? Now they are justifying going out of ATX specs by standardizing high ripple?

[jonnyGURU]

I'm afraid all of the Epsilons list a 200mV ripple/noise in the specs.

So, yes.. they're taking the path of Aspire/Apevia and their 10% of +12V and figuring that if they list it as spec, they're not wrong. :(

[Super Nade]

Wow! Didn't expect this from the company who own SPI and 3Y! One would imagine that their Rev 2.0 stuff would have fixed these issues. I wonder how their Zalman OEM'ed units turned out to be better if its based on the Epsilon design?

[Oklahoma Wolf]

I think the design has been improved through use of the 4 Teapos replacing one of the OST's on the output, but it could be that redoing all the spec sheets and possibly recertifying are more of an expense than they want to pay for.

[Makalu]

well I can't seem to avoid playing the devils advocate but if the FX/GXS units didn't actually exhibit out of spec ripple and merely pretended to allow out of spec with ink then Aspire wouldn't have one up on them :)

[jonnyGURU]

What are you talking about?

The FX units DO have that bad of ripple and Aspire power supplies can go 10% out of spec.

Or did I miss some quadruple negative in your sentence and totally miss your point?

[Makalu]

hmm major deja vu...yeah I know that the FX units do have out of spec ripple on your tests but the two Aspire branded units you tested didn't go out of 5% spec except on the crossload tests...they just crapped out well below their total watts rating and happen to be an old design built by people with no thumbs etc. etc.

[jonnyGURU]

Oh.. ok... It was the whole "then Aspire wouldn't not have the one up on them that they don't have" part that confused me. :p

Probably at peak loads that are within their max power but not run for longer than a few seconds an Aspire is within 10%. Perhaps moments before blowing up they're within 10%. :D

[Makalu]

well I only have the two units that you tested to judge by but your review says that the Beast 680 consistently latched off with anything higher than 34A combined on the 12v's (566w), and the Darkside 600 consistently blew a fuse whenever you tried to get 550w out of it. Sounds to me like both units were peaked out and yet still well within a 5% tolerance according to your voltage measurements, so I'm not sure what you're trying to say here.

perhaps these companies that contract out to these PSU manufacturers have more input than so called people say they do....hmmm

But Jon, from the spec I download from their web it seems that the 700w & 600w version is still on 120mV ripple spec

Maybe only for 760w version they pushed it too far and hope customers don't aware of this ripple spec? :D

I get confused with their FX600/700 and Epsilon 600/700 because it seems to be the same products :confused:

Any idea Jon?

Any chance to do the retest for the newly revised epsilon here Jon?

[CAD4466HK]

On the FX-700 specs pdf., did anybody check out section 4-6, and see the OCP limit on the rails :confused: :eek:
60A on the +3.3V :eek:

The PSU's "failed" MY tests, but they don't rate peak load with a static load. They can trigger a 34A load for a split second and not trip the power supply. That's all I'm saying. Theoretically, the Aspire could do a 34A load for a split second and not trip, and maybe during that split second is when the voltage drops 10%. That's all I'm saying.

Remember: I'm not really testing for peak loads. Loads have to be sustained by the power supply. :)

Not the ones that I tested or the one the GameXstream is based on. I don't have time to look the PDF up right this minute, but the 600W and 700W do say 200mV in the specs. I remember it clear as day.

You going to buy the units?

[Super Nade]

JediYODA, I think Wolf answered my question very very convincingly. ;)

ah ok, thanks for clearing that up for me :) I always wonder about units that maybe do fine under a static load test but might not handle the kind of dynamic load changes that a CPU can create within microseconds and no ability to really measure that with a DMM.

[Spectre]

perhaps these companies that contract out to these PSU manufacturers have more input than so called people say they do....hmmm

Or it could be different models lines have different characteristics since they aren't the same design. :rolleyes:

Sorry packo but you are still wrong since it is the Epsilon platform that has the problem.

[nat_raven]

You going to buy the units?

Actually those unit are into my consideration for my new PSU since my Topower 750w just died innocently :o

Mostly I lived at Singapore and it seems that the pricing for Epsilon is quite reasonable comparing to other brands. Yes, I know that Seasonic build Corsair or their own brand or Silverstone is a better products but at S$ 200 (US$130) it's already a bargain here. Seasonic or Corsair or nice Silverstone is almost S$300+ here. We here don;t have such luxury like you guys to buy OP650 a $129 :(

[Bbq]

In Singapore, they have Seventeam PSU's. From what I hear, they're not too expensive, either.

Food for thought.

And here, Epsilon's are also very cheap: You're looking at continuous rebates for under 90 for the 600w model. Makes you question how much they realy cost to make.
