Is getting a 550Watt PSU with NON-PFC is recommended for overclocking? Is it really important to get a PSU with Active PFC?
-TQ-

APFC is not important unless you're using a UPS or your area's AC power fluctuates (which in that case, you should be getting a UPS anyway). A side bonus is that APFC psu usually have better power efficiency as well (do not confuse with power factor). Otherwise, APFC is not important, just count it as a bonus feature.

@loh
should learn about psu from you, ur master

Thanx bro.
So there will be no hesitate for me to take a 500 to 550 watt w/o Active PFC.

Not yet.

Maybe after CNY.

want to ask here.,can i use cooler master 520w modular for powered my rig.,my rig as my sig..tq

of coz can la my friend...
which model? and how much ur orice? hehehhe

need a psu for OC purposes..
my budget is around RM200..
is there any in the market??

Silverstone Strider 400W PSU but whole LYP no stock.

Is this psu wayy better than those enermax FMAII 460W?

@ocz
Hmm i dont think you can compare it that way. FMA 2 are pretty neat psus.

Thanx bro.
I am still wondering about the ST400.
Can it support a X2 3800 3.3Ghz,1X DVD-RW,1X HDD,1X HD3870.

I still dont have any psu ATM.

@ocz
i have used my St400 for ocing my proc to 3.44GHz and my ram to 1150Mhz. So i have no doubt that it can handle your system, Though i am concerned about your HG3870, this is where you have to consider the 12V rails.

I would suggest FMA2 535W, if you can afford it or the ST56F, Fma2 might do the job well. Hmm but st400 i am not too sure man. This is solely up to the railings and what your HD3870 needs .

I would suggest you to google, POwer supply calculator and go to xtremepsucalc. Get the power rating and come back here after that

Well,thank bro.
Let me check by calculating the power consumptions 1st.
Whats the approximately power for the 12V rails.
Thanx bro.

@ocz
well normally for 400watt psus it should be around 280Watts and above i think for the 12V rails. I am not sure on this

for +12V Rail, it is highly recommended that you get at least 30A either single or combine +12V Rail

@sniper

which refers to either the fma2 or strider 560watts OR the ZEUS 560WATTS

i'd go for Zeus 560W

why?

it's single 38A +12V Rail, non-modular with 80% @50°C (they claimed )...

Zeus are meant for servers so I think it'd have higher efficiency and more reliable. ST56F ain't bad though

sniper tukar avatar, brape ramai dah kne tembak?

hi there.,i want to ask.,i want to change new psu.,can anyone recommend which 1 is better gigabyte odin pro 550w or cooler master real power 520w modular psu..tq
