if it states that the PSU is 1kW, does that means it draws 1kW of power constant even though we use... say...400watts? or does it only draw 400 watts (the amount that we use) and the maximum it can supply is 1kW??

quite confusing as some say electricity bill goes up and things like that..

fortunately, first assumption is wrong. 1kW will be the average maximum power deliverable available to system. So if your rig draws a maximum of 300W, that PSU will only deliver maximum 300W to your PC. So second assumption is correct

Power consumption thread just to give an idea....

http://forum.lowyat.net/index.php?act=ST&f=3&t=304293&st=0

99% of the forumer's rig here won't breach 300W lor.

almostthere,

since that's the case, then why is everybody saying that getting that 1kW PSU will give a large sum of electricity bill?

so in another words, if my pc demand 300watts to run, the PSU will only draw 300watts from my main line to run it. now that clear things up a bit!

aiya ppl...

using a 1kW psu on a lower wattege rig WONT INCREASE UR BILLS!!! Duh

it simply means tat the 1kW PSU can handle up to tat much load...
besides, a good PSU like Enermax has high efficiency level..meaning less % of power loss...meaning save on electricity..meaning lower electricity bill....

sure not all of us need a 1kW Galaxy...tatz y there r other range to b choose from..tatz y got Enermax Infiniti/Liberty/FMA II...tatz y got Liberty user like me around....

Lotsa ppl think Enermax is more expensive...well, i think slightly only.. BUT it worth every single RM$ spend...
i said so cuz i've tried myself few other brands OR non-branded cap ayam PSU..which no mood 2 comment further la..sigh...

Because everyone here (mostly) are bloody morons. Yeah yeah i sound like a prick saying it, but heck atleast i'm a prick that tells the truth. Unless LYN forumers are prepared to back it up with sound science, don't believe them.

It does makan a little bit more electricity.... melts the polar ice cap a lil bit more.... drown the Maldives a lil bit more...

In the sense that most psu have a efficiency range between 40-70% thereabout... so if you draw too little.. too much power will be wasted as heat.

It won't be much in terms of $$$ but think of the furry lil animals

haha...pity those lil furry animals then...those wasted energy changed in2 heat & those creatures got 2 hot... so hav 2 beskinned temselves...

btw, for Enermax PSU...their efficiency is around 80%
their infiniti series got "80 Plus certifications"...with efficiency of 80-85%

Marketing talk and again..that depends on the range.

My rig draws 160W idle and peak around 209W (which ppl spend the most time downloading pron or surfing for it) measured from the wall.

http://forum.lowyat.net/index.php?showtopi...dpost&p=8605105

So if I use the 1000W Galaxy...I'm only getting ~77% efficiency which means 49W is wasted as heat

But let's say I use a more efficient psu like the Seasonic S12... at the same 160W-209W range.. I'm getting 87% efficiency.

http://www.silentpcreview.com/article247-page4.html

In this case.... I only lose out 28W.

= 21W difference.

This is enough to power my pron rig which draws 21W idle or that light that your mom always reminds you to turn off to jimat elektrik.

hey bro,

how come u calculte Galaxy with ~77% effeciency only?
actually it runs @ 80-8% efficiency from 20% to 100% full load...

u said ur rig draws only 21W idle???walao...sure ah?
share with us ur sys specs la...IF u dun mind

Again...that's what the marketing says.

Read the review here:

http://www.silentpcreview.com/article726-page4.html

Usually SPCR's psu reviews are much better than the usual "test with hardware and pop screen shot saying prime stable" so called "reviews" that other sites do.

As for the 21W... that's the PrON rig ... specs as per my siggy.

Measured from the wall plug here:

Enermax go hell lah.

mine FMA II 460w RM285 use less than 6 months now went to "Holland" already.

Regret to bought Enermax. No more next time, sorry for enermax.

jimlim007,

look at the bright side, it's only your PSU got kong off.. enermax is one of the good brands for PSU.
rumor has it that enermax PSU can stop sudden surge without causing damage to other parts etc.. mobo, ram, proc, HDD and the list goes on. in another words it sacrifice itself.
correct me if i'm wrong.
as i was saying, look at the bright side, it's only your PSU RM 285, what IF your mobo + proc +.... got fry ... = >RM285

regards,
point blanc

haha...cool down la brother...

i totally agree with Point Blanc there....think bout wat would happen if u r using a cap-ayam/normal PSU....how much damage it'll b then???

but cant blame u as most ppl's mindset r simply set @ "i paid so much 4 this product...it should've work till i'm 80yrs old or smtg...!!!" RITE???
IMO tatz way tooooo naive...

Do find out more bout safety features included in a good PSU like Enermax... such as OVP, OCP, UVP, SCP, OTP...list goes on...

I totally disagree.

For mine psu issue not involved lightning strike. So, at you said, Enermax must have it's bottom line level to satisfy their fans at least can opearation for couple year lah. Not to say less than 6 months. That is very horrible and terrible.

What for spend rm285 go bought a psu can only survive for couple of months only. And what happen when mine current RM48 psu Kingmax can survive more than Enermax.

I am for sure agreed Enermax is one of the famous brand for PSU. That is why i bought Enermax instead of Cool Master RM300 or Antec ot etc.

Hmm.....really dissappointed of Enermax's supreme performance. Haha, it is went to "Holland" for vocation after operation couple of months

6 months, you can still RMA your PSU.

Yes. The pc shop owner said need 1 month at less.

So, me have to waste 1 month streamyx usage RM66 + RM26 one month billing. And I am the kind of usr that can't survive without pc even in one day

That is why we always need back-up components just in case the current component that we are using failed.

Nowadays wee see that the current hardware uses more power each day. Those times where a 300W PSU should be more then enough is long gone.

It seems that the hardware manufacturer especially the video card/GPU and some CPU maker also doesnt care enough on the power consumption as long as it can deliver super high performance with their card. Rarely we seen an advertisment that says "New 9900GTX super fast performance with only 50W power consumption!" since the consumer itself doesnt bother much about the energy they waste. And they could care less since the power consumption is still considered small compare to Air Conditioner and Refrigerator.

But when is this more power more performance theory will go on? Do we really need a video card that eat 500W of power? Maybe in future some Computer organization should draw a line on the maximum power consumption on several parts of the computer like the FIA did with Formula One Engine, example maximum power usage of graphic card is 100W per card. And with that, GPU manufacturer will mostly competing on making a high performance card and yet low power consumption that will surely benefit our eco system.

Therefor this will surely benefit us consumer interms of electricity bills and dont have to buy new PSU unit when new graphic card is launched as well as saving those furry lil animals from extinction.

Hmm...i use core 2 duo e6600, very saving power leh. Enermax FMA II still went to "holland"
