Sager (7280) Clevo (X7200) Power Supply Issues.

I wonder what would happen if you removed the trip switch, that trips at 380w? Apart from the obvious possibility catching fire?

 

Is there any reason why laptop psu's can't be made "digital"? I'm talking about modern psu architectures; "switch mode", "ICEpower" psu's ... these can be made considerably smaller and cooler than regular old psu's. Some of today's high powered audio amplifiers are equipped with these, so they should be able to produce the voltage and amp's needed.

 

That's a good one!

:laugh:

 

I believe a 2.8ghz, 95w, hexacore chip with dual 5870 gpus could fit very well inside the psu. Also, a 460m/470m sli with a 130tdp cpu could also fit the 300w psu. But no, oh no, they had to go with 980x and 480m sli. That's just looking for trouble.

I just want to see a x7200 with different gpu options. 480m sli is just a wallet melter.

 

Maybe this was the issue that delayed the system but it never got fully resolved.

 

Did cross my mind

 

I spoke with a Clevo tech in europe, I had to go further into this problem.
We are going to see is 460s in these machines by mid month.

I think I will follow speedy and return mine and my sons unit and wait for the 460 versions. I don't like the huge powerbrick and I don't want it to be any bigger. I could have built a lan box for half the cost and have twice the power. The reason for my purchase was semi-mobile couch, lan party gaming. Did not want to lug around a generator. As joker5150 said wait for rev 2 mid month guys.

 

Can any of you resellers give us a date on the 460m versions US arrival, I am sure you know this answer.

 

Glad a lot of people are looking to rectify this But all customers, not just sli customers, should get the beefed up PSU, I want a future upgrade to sli!

 

Someone know if the x7200 psu is compatible with W870cu ? I got a complet shutdown after 2 min with any TDP/TDC higher than 55 and 26/25/20/20 OC. I have a li-shin 160W psu right now... and all my temp never go past 81'c ... Someone have a hint ?

 

Dude, Where you been, these supplies are switching mode. The problem is you cannot make them any smaller than they are already. This technology is very mature so what you see is the state of the art today.

If you had a 300-400W linear supply they would be huge.

 

If that worked then you would have limitless power in that notebook!

haha

 

Oh really? I was not aware of that. I have a switch mode supply sitting in my 2 x 800W audio amplifier, and it never gets anywhere near as hot as my laptop supply. And it's not all that much bigger than my laptop supply. Which is big enough. My other amp, a 2 x 250W class A with a "normal" supply, do - but it's also 5 or 6 times the size of my laptop supply. So I just didn't see how it could be that these supplies actually are switch-mode. Oh well. So much for my brilliant idea then...

 

There are also alot of characteristics about the laptop psu that are almost definitely different from your speaker power supplies. Those added features take up more space

 

Honestly, I would think it is the other way around

PS: I am not stalking you (yet)

 

The power supply to the speakers is essentially an amp with some regulation and ripple suppression built it. I do not know if it would be auto ranging or not (for universal AC input). The power supply for the laptop is strongly regulated AC/DC conversion with built in surge protection and some other features (internal logic for overpower protection and current limiting circuitry)

I would expect the Laptop PSU to be the more complex one.

 

lol i wonder what that bwebcoder is gonna say to all this

 

He is too busy driving his Porsche and running his large animation studio to worry about this kind of stuff.

 

I think he is still here just with a new name .

 

I was thinking that dual PSU's would be Dual 300w's but it doesn't have to be, it could be two smaller 190w's, or 220w's

If they were 2/3 the size it would be ok. Rather that than being de-tuned

 

lol

10char

 

I want to come out to Sager right now saying I am against a SLI power supply solution. I carry enough stuff when I travel another piece is one more thing to worry about.

Create a higher capacity power supply instead of running 2.

 

Laptop supplies are of a simpler design (if you can call it simple), you can get away with just brute force. Audio on the other hand, has more issues that need tended to. The two biggest problems are the Line voltage hum and the switching harmonics that get down converted to the audio range; this creates noise that is hard to filter.

Where I work we have audio, and we use switching supplies, we play hell with “birdies”, which is caused from the switching supply noise coupling into the audio. You have to play tricks with grounding and filtering to reduce the problem.

On occasion around here you hear of people who have noisy computer audio, that can be caused from this coupling from the power supplies.

anyway....

 

Their cheapest option is changing the bios, but if they do that, they completely miss the point of why people buy, people want the most powerful laptop on the planet! Take that away and you loose 2/3rds the appeal/emotion.

Again, Furmark pulls more power than the psu can handle and shuts it off, according to the review!

 

And yet, the AnandTech guy don't view that as a particular, or significant problem. And neither do I, really.
What is of more concern, is if the power supply shuts down during playing Mafia, as Speedy reported.

That the power supply shuts down during stresstest loads that you never would encounter using ordinary programs or applications, does not concern me. That it shuts down using "ordinary" programs or applications do.

 

I thought the hanstarr display was LED? They said it's CCFL in the review. Apart from the contrast ratio, the rest of the numbers for the LCD were abysmal. Jarred points out how much he likes the RGB LED displays that Dell uses (M17x-R2 ) and that's something Clevo needs for it's top shelf system. If not RGB LED, then at least IPS.

Did you guys see the GPU temp? 102C under furmark? Wow!

 

I could get that running Furmark on my GTX 280M, nothing new there.

 

Furmark doesn't go above 78C on my system even with xtreme burn. 102C is terrible.

 

It's only terrible if the card can't take it At least for short periods.
During game playing, I have never seen my card reach 80c.

 

more than terrible. now we have 2 persons reported 102C from x7200. one from member here and another one from anandtech. it seem clevo did very bad job in cool down both gpu. primary gpu go 91C even in normal gaming from anadtech review.

 

I was playing StarCraft II on ultra, real nice, but my primary GPU went to 80, i realised my PSU was just behind the machine, and the machine was too close to the wall, so i moved it away and stopped playing, it now down at 49. Ive over clocked the CPU to 3.75, its was sitting at 71 during sc2, its also come down to 51.

So now its cooler i will go back in and try again....

 

The 480ms are the same as the 480 desktop versions power hungry, noisy, poorly designed.


I am so happy my 7200 is being returned and shipped back to me 3rd week in October with dual 460s. I end up saving massive amounts of money and will have a quieter more reliable system.

The review they use c300 !!!! Why do I read on these forums they don't work.

 

Here we go ive been playing sc2 full ultra setting for 40min temps are as follows
Max temps
Primary GPU = 79
seconday 69
CPU all core 73

What temps should i allow as acceptable?

 

These are perfect

 

Yeah, considering the nature of this beast, those are really surprisingly good. I could easily reach those on my system, which is non-SLI and does not contain a desktop processor nor chipset.

 

What about math calculations. Some tend to use everything (cpu, gpu) to the max.

 

Some CUDA examples use cpu and both cards at maximum. Try running some of those for a few hours.

Maybe they had the power utility from Clevo turned one while doing that. REad the review from Anandtech

 

Hitting 102c even under FurMark is bad.....my laptop GPUs max out at 68c.....with no cooling pad or anything.

Some games will get your GPUs just as hot as FurMark does. Crysis is the first to come to mind but there are newer titles that will push as hard.

 

Agree! looks good.

 

I am using the c300 in my x7200 and it works flawlessly. My best guess as to why some peoples aren't working is user error, maybe they didn't format them? Also, I have to guess that installer error on these gpu heatsinks has to be the reason for the high gpu temps.

 

Are they raid 0 ?

 

They will work just fine, but only at SATA II speeds because the SATA controller is SATA II. There isn't a SATA III controller made for laptops yet, and only some of the desktop boards have them.

Therefore the main reason for getting a C300 is its extra capacity, not its speed.

 

No, just one c300 for my operating system and software, a 500gb 7200rpm hitachi for my working data, and a 500gb 7200rpm seagate as a scratch disk for all of my temp files (to preserve the life of my SSD). I know someone on this forum will let me know whats wrong with my setup , but in my experience this is the most stable way to operate when your doing my type of work.

 

Thats very relative....speed. I am running that c300 and its damn fast, alot faster than any 7200rpm drive I have used. Maybe it isnt being used to its full potential, but it is surely adding speed to my setup. If I wanted extra capacity I would go for a 750gb hdd.

 

My point was that the C300's are a lot more expensive than other SATA II Solid State Drives, so you won't get more speed when compared to another SSD...not when compared to a magnetic drive.

Therefore the only reason to get a C300 is if you want more capacity than say an Intel X-25 or other SATA II SSD...otherwise there is no reason to spend the extra money on a C300.

 

I don't think SATA III even matters, most sequential read/write of any SSD/HDD is not even reaching the limit of 3.0 gb/s of SATA II yet not to mention 6.0 gb/s. Moreover, sequential read/write is not even a matter for normal usage where random read/write is what matters, and random read/write speed of even ssd is not even close to limit of SATA II.

 

Absolute rubbish, you have no idea whatsoever about ssd. Don't speak until you know what your saying.

 

Huh? Please enlighten me on where am I wrong then.

Last I've checked, Sata II supports up to 300MB/s transfer speed, and the fastest ssd C300 is only around 320-350MB/s for sequential read. Could not even touch 200MB/s for random read/write at best case scenario and not even reaching 100MB/s for worst case scenario.

So yes, please enlighten me on how am I wrong.
