acbel is the OEM for coolermaster PSU anyway

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"...

Is there any shop in LYP that sells PC Power & Cooling 1200w PSU? Juz wanna know the price 1st, love their 750w PSU, but thinking to upgrade to 1200w.

Ask those i know who are working in Czone and Viewnet.... they said its like that, don't expect much from it; you pay peanuts, you get monkey..

Want better one, should op for something better like Antec, ENERMAX, DELTA....

Is your coolermaster 460W PSU is active PFC type ? The buzz sound is produced by the active PFC circuit due to resonant. This is normal. My HP C8000 Unix server power supply also like that. The C8000 700Watt PSU is made by Delta Electronics.

It can be solved... depends... I ever changed the MPP 400V cap to another brand and the buzzing sound stopped. Will post photo later...

Modular or non modular is better??

newbie here...
im thinking to change my gc from 8600GT to 9800GTX+..
the psu im using now is enermax true power 405W..
im wondering if the psu can support my whole rig?
AMD 64x2 6000 3.0GHz OC to 3.19GHz
ASUS M3A
1GB DDR2 RAMx2
2 SATA HDD

wouldnt be enuf i guess..better chg a better one lar..make a budget....let say around 450, get a pc power&cooling 610w silencer den...

so does it mean that 9800GTX+ requires much much more voltage than the 8600GT?
im oso considering in changing the ram.. so not much budget left dude..
will it be enuf if ENERMAX 500W true power?

Personally, I prefer non-modular or fix cable as the contact loss is at minimum.

erm..modular MAY hav some power loss unlike non-modular...but nowadays modular psu shud be fine...

9800gtx+ sure nid lots of power den 8600gt..9800gtx+ requires extra pci-e connector..enermax psu?500w?which model? perhaps u shud get the ocz 600w stealthxtream...go survey around and give us ur budget

Try out this baby. Saw in recent OCC organsied in Taipei. Its the official unit used in the event. looks cools ...
