400W Power Supply for Clevo D901C

I just get very good Power Supply for my laptop 400W Real Power and can be set from 15v-28volts
Original Clevo PS is Level 3 this is Level 5

here some pictures:

 

How confident are you that the new PSU you've got is going to work well with the D901C and not blow things out by overloading the circuitry?

 

because i try it and it work perfect this power supply is military model
i even make some stress test and the two fans keep the ps very cold
it can be regulated from 15volts to 28 volts

 

Where'd you get the PSU from?

 

from one military lab they dont sell them i get one because i know one guy that work there

 

i just play Medal Of Honor with this PSU for 1 hour with Clock 670-1700-950 and everything is good

 

Ahh, that explains the lack of general info....

oo ya but here you have to wrote in english

 

Add one more from Kent UK

ZDR.

 

yep, how much and let me get my order in..

also gangstaone: is there any way you can attach a kilowatt meter to it and gage how high the watts go.
i have found that our original adapter will max out at 259 watts.
also, does it have any auto voltage regulation or just set to like 20 volts and that's it?

thanks

 

yes you can regulate the voltage from 12 to 28 not from 15 to 28 like i wrote first and the Real power is more than 400W in stress test and games with both cards on 650-1600-950 with only one fans working (the PSU have two)
its stay cold no heat at all

 

i get one because i have friend in one military lab that make PC Tech for our police and Military they get this Power Supplys from England military i think
and you cant buy one

 

the power drawn from the socket will always be more than the PSU is outputting to your laptop as there is a loss in AC-DC conversion of generally ~20%. Therefore if you have an output of 220W, the input will be around 275W. My 120W PSU draws a max of 170W, which is a bit less than 80% efficiency (or a bit more than 120W output)

 

yes i know but this is not ordinary Power Supply and when i say more than 400W i mean this is Real power that can be used

 

so it's rms'd at 400 watts then?

 

what......?

short version. if it's rated at 400 watt's. is that max power or rms power.
edit: forget the super tech details, but umm...can you get any more of these?

 

i say that we test it and push it to 460W and can go higher but we didnt have time to play then and i didnt want to know how higher can go because this is enough for me

 

You ask me if i'm able to get more Power Supply's right?

 

yes, i would like to get one or two of them if at all possible.

 

Sorry i cant get any more

 

ah, well it was worth a shot. thanks though

 

I did a search on the model number and there are some for sale on the internet.

 

yeah, i found it as well. 217 euro or what ever currency is in the UK.

they have them here in california as well.

:O That'd be the pound!

 

thanks!....

 

oo ya there is like mine LPS254 CEF

 

Where did the 400W rating come from?

And that's Max, not RMS.

 

we test the psu and we get little more and 400w

 

that's on the LPS250 - His is the LPS254(isnt that what he said?) - However, simple formula for you guys to consider..

P = I x E(v) - or Power(watts) = Current(amps) x Voltage
So, using his stats.. he's @ Max output of 48V and 10.4 Amps. Odd though, cause before he said it would max @ 28 Volts. Anyhow..

Watts = 10.4 x 48 = roughly 500.. That's max. RMA would likely be 70-80% of that, so 350-400 RMA. Not wasting my time to do EXACT math. Not worth it. Sooo.. 350-400RMA @ 48V - Well.. if he's saying his maxes out @ 28V, then that's a little less than half of the full 48V rating which in the end doesn't really matter because I just realized that they all run @ 10.5 amps.. so 28 x 10.5 = 300 MAX or 250RMA roughly.. sorry for any confusion there, I overlooked that. Regardless, IF it ran @ 48V then yes..it would be around 350-400 RMA, but since he stated TWICE it runs @28V max, then his RMA is right around 250. Sorry bud, but you got duped if someone told you otherwise.

 

thats why i wanted to test the psu before i buy it and i have test it twice once there in the lab and once today in one shop for electronic max rma is 430-450w 26A on 20volts

 

RMA? Return Authorisation Agreement?

Or RMS, Root Mean Squared?

And I was going by the datasheet stats:

Code:

Model    :    Output    :   Minimum :   Maximum Load   : Peak  : Regulation2 Ripple
Number   :    Voltage   :   Load    :30 CFM Forced Air : Load1 :            : P/P  (PARD)3
LPS254-C : 15V  (12-24V):   0.50A   :      16.7A       :  20A  :     ±2%    : 150 mV

So in short the LMS254 does not go to 48 volts (although the LMS255 does) and is rated at 250W, hence the name LMS25x.


DOH! Just reread your message and see you actually agree with me. Hopefully the OP will pick up the points...

 

Sorry for posting again but how are you measuring your power rating? Amperes consumed by the power supply? In which case take into account it's only 75% efficient, at best, and your number again drop down to a little over 300W.

 

i have real power on this 26A our original is 11A
if 11A is 220W

 

ok, you guys are loosing me now...lol
if you go by the formula you also have to remember....
it's 24Vx16.7A=400.8. right? minus said 20 to 30 percent or so...?
now if the laptop runs off of 20 volts flat. then it would be...
20v*11a (our power adapter)=220. they say is max, but i can push it to 259 watts.
im using a cyperpower battery backup 900 watts with KW meter to measure.



this is all interesting to me....

 

i have also download info guide for LPS250 series and there says that LPS254 CEF is 12-24v but mine is 12-28v

 

when you tested it gangstaone..did you use "your" laptop at the place where you got it.?

 

no they have a machine to test power supplys i just try if works well on the laptop

 

then that's why. makes perfect sense now.

this is why i asked you about the auto sensing stuff earlier in the thread.
even though the new adapter is rated at "28" your laptop is not going to use "28" volts it will use far less. more like 22 or so volts. which could kick the amps up to 16.8. giving you a total of 369.6 watts or a little above 300 to 310 watts real power. but non the less it's far better than our original one. so im sold on the idea.

this is all based off of the formula. now the specs they shoot out suggest 250 watts max...interesting to say the least....

 

john i didnt test it on 28 volts i test it on 20volts both times

 

Nevermind that post.. Theres a possiblity this thing pushes near 400.. but, I need to do more math

E-wrecked i didnt buy this from odrinary shop i get it from military lab thats why they maybe not the same i dont know

 

It's all good.. If it's the BOLD one john highlighted..then it would all make sense. Quite impressive I'm glad it works well for ya. POWER! *grints*

 

well i pay alot it has to work good
