ok, i have a very important question here. 4 me at least. As power supplies keep getting more n more powerful, and what i know already surpassed the 1kW barrier, DO WE NEED THAT THING REALLY? Lets say, i want to build a machine with a Quad Core CPU, 2GB DDR3 (or DDR2), 2 SATA HDD, an 8800GT card (without all that extra coolings n overclockings). How far must i go to get a stable working rig? if i use the calculator, i think it NOT EVEN REACH the 400W mark. Am i rite? And any suggestion what power supply brand/series that is great and sufficient (not the greatest beast) out there? it confused me when it comes to power supplies. Silverstones, Enermaxs, Thermaltakes, Antecs.. whats that? and what about odin by gigabyte? well gigabyte is popular with mobos, but im not quite confdnt if it is a PSU....

thanks 4 your help. im just a n00b here.

GUys, I have a question. I tried the PSU calculator by extreme.outervision.com

My system setup says that if I use a 8800GT 512mb and 7300GT 256mb is still the same watt for the PSU. Why is this so? I tot the 8800 series need a powerful PSU? Plus, my rig with X2 4400+ and all it says the watts required is just 287W o_O

So does it mean if I continue using my coolermaster eXtreme 430W I can upgrade and use 8800GT?

guys will this PSU

PowerLogic M1200X (ST)+220w
can run this setup?

-AM2 Athlon LE-1600 2200+ 2000MHz
-MSI MS7309
-Apacer DDR2 PC667 RAM 512MB
-W.D. 80GB SATA2
no OC, not necessary to upgrade the GC coz on board GC will be enough. no 24/7 use just normal use.

TS, there is another psu calculator which i find it is very useful yet free. the cons is you have to calculate yourself for 15% aging if you use the psu for more than 1 year 24/7. anyway use calculator isn't hard.

oh ya..btw it's in chinese.

icute, powerlogic, enlight are chapalang PSU...how much is your budget? Will you upgrade or add ram, hdd? I think 350W PSU should be enuf for you, Enermax FMA II 350W can get at RM159 at All IT...other shop seem do not have 350W edy...

how about icute 450W ?
i hope its good though. isit better, no?

basically my budget is very low. so, with the computer gona be use by kid to play. i think cheap2 psu is good though , no? coz u see, i will not add on graphic card later , i will not do any overclocking , i will not even turn it on for 24/7.

Thx in advance

What you guys think about Corsair VX450

Any PSU below RM290 to suggest for this specs

E8400, 1gb x 2, 9600GT OC

vx450 can get below rm300 r?

how about mine?

HDD : 500GB Seagate Sata2 16MB
GC : HD 4870/HD 4850

confuse on which PSU should i buy T_T. budget 300-400 but may consider up to 450 if really worth it.

can suggest me PSU suitable for my setup?

mobo:Gigabyte GA-MA78GM-S2H
proc:AM2 X2 4600+
RAM:2Gb DDR2 800
HDD:250Gb SATA with possibility to add only 1 more HDD..

yeah... im using onboard video..
actually this setup is for new pc.
is silverstone ST400 ok?

what happen if my psu supply more watt then what my rig need?

Both sufficient. They also quite good PSUs. Go for gigabyte if u want modular PSU.
Better u pick Pro instead of GT if u dont need any power/amperage monitoring tool.

HX520 or VX550 la then
odin pro oso gudd.......
i would buy odin pro rather than odin GT
cuz odin GT only have that psu software control

i dunno anything abt huntkey.but i can tell u smtg abt gigabyte superb. u see rite,my fren bought 1 of them.550 watts gigabyte superb. in the end, if u read the label, u'll understand tht its actually a 450Watt true power PSU.kind of cheating.

erm...it goes the same to huntkey...plz note that...dun say cheating...it did mention the power...but did not specify true power or peak power..juz like huntkey greenstar 550w, its 450w true and 550w peak..but it is capable of going up to 550...who says cheating? guess its a way of advertising

no short circuits or anything bad right?

just wanna comfirm

What's the best 460w PSU(below RM200) now? Want to use it for E2180 and 8800GT, should be enough right.

what is the diff from GIGABYTE ODIN PRO 550w FOUR 12V rails...and CORSAIR VX550 single 12V rail???

what does it mean?

which is better for my rig..(see my sig plz)

btw, i want to install a 4-5 more fans inside my casing

Hmm.... the buzzz... Check and see if you had plug in the power connector properly. AFAIK the buzz usually occurs when your power connector not plugged in properly (ie. contact problem, connector plug too loose, connector plug too tight and slightly bigger than socket until cannot fully insert the plug all the way and the contacts inside not fully and properly joined), move or shake the power cable a bit and if experience more buzzing or not...

I'm using AcBel too but never experience this "buzzzz"... 

Mayb bcos x2 eat ups more power...

Mine also i think a bit risky, seems just enough to power up the whole system... just hope it would be enough...
Is there a way to personally calculate the usage ? i did try the Extreme PSU Calculation, but my PSU doesnt seems to be giving enough...
So i want to calculate it myself see if its really enough or not...

lol, so my electric bill will read as 528W rite, not 700W..

lol...
i oso duno..am looking for one

would like to show this thread from Vr forums on an OC-ed rig
with 3 x GTX280 SLI power consumption

http://forums.vr-zone.com/showpost.php?p=6...&postcount=2744

it idle @ 300-sih Watts and peak at about 900~940W

so those buying HD4870 alone please no need to get a 600~700W PSU hor. a simple good 400~500W PSU can liaoz.

Lets put it like this, the gigabyte superb720 is like those gas guzzling cars, (those car which are 3000c and above) It's sold at a reasonable price, it has performance and power, BUT its expensive to maintain. Anyone who ever owns a Mazda RX-7, Mitsubishi GTO, Toyota Supra, etc. will know what I'm talking about.

OK here's my opinion, that PSU cost RM240-ish, in a 1 year usage of PC with that PSU will burn extra RM100 from your pocket.
So technically you spend: RM250 + 100 = RM350-ish annually/yearly if buying that PSU.

So technically speaking, u can get any other PSU that cost around RM350 OR you buy that GigSuperb720 for RM249 + about RM100 of unused reserved power.
Both are the same price.

Anyways with 80Plus Efficiency you saved up at least 35% from the unused reserved power in a years worth of PC usage,
so realistically u might pay extra RM50-ish depends on how much u use your PC in 1 year.

(my opinion is solely based on budget and how much money involves, you can choose to ignore my advise if budget isn't your main concern)
But if u can top-up the budget of that gigSuperb720i, you should buy PSU's the likes of:
Corsair TX650 and above, FSP Everest 80+ 600wModular, Siverstone ST series, Xigmatek NRP series with 80Plus SLI/CF certified, etc...
