Wah, you could spend a fortune on two units of 8800GTS, but couldn't afford even a simple Silverstone OP650?

Get real dude.
CM, euwww..

It's not even in the tier list.

X2 3600+ Brisbane
8500GT

Is it enough to use Enlight 420W (Model no: HPC-420-102-DF ) for this rig? Not sure its true power or not..

from wat i heard from online..min 26A is required for each rail for high end system...and it is better to have less rail ..

the online psu calculator is just a reference for us..not the exact value   

if 26A per rail is considered just okay, what about all those high quality quad rail psu like FSP epsilon? epsilon cannot power up a 8800GTX?

My rep at Silverstone said the following:

After receiving similar feedbacks from elsewhere, we went back and found that the noise was caused by the very fast response of our power supply to compensate for loading changes. The transient response of our Olympia/Decathlon is excellent but this also results in noise that people hear due to the frequency it produces. We have since made some adjustments in our subsequent production runs to slow the response time slightly so that the frequency is more difficult to be heard by human ears.

We are open to offer free replacement to any customers that find their power supply has unacceptable high-pitched noise.

I think perhaps the response given to SKYMTL should have been a lot more detailed and worded a little better. So here goes my first post at jonnyGURU.com!

The transient response performance that our current Olympia/Decathlon 650W ~ 850W can achieve is best in class (also best that we've ever had). The goal was to have power supplies with top-notch performance not only during static loading (which is what most power supply testers do) but also in dynamic loading conditions. Olympia/Decathlon 650W ~ 850W models can react to sudden changes from high load to low load (and back) quicker than any power supplies that we have tested.

Unfortunately for us, this high performance also results in transfomer to produce frequency that a few too many people consider noisy. Believe it or not, we can have three people in the room listening to the same power supply with one person claiming that he cannot hear anything while the other two can identify the noise as either acceptable or annoying. We ended up testing many high wattage power supplies from our other series/other companies and found that practically all of them will make noises but with different frequencies. Our Olympia/Decathlon 650W ~ 850W on average has higher frequency while the Strider lines has the lowest (therefore inaudible to human ears). We found that transient response performance was almost proportional to frequency of sound that a power supply makes.

Since we do not have enough evidence to show that having "excellent" transient response is better than merely having "great" transient response in real world usage, we decided to scale back this aspect of Olympia/Decathlon 650W ~ 850W’s performance in our subsequent production units to reduce the sound frequency. If you have a pair of sharp ears, the noise can probably be heard when you put the power supply next to you, but they will not be detected when used in a PC anymore.

Contrary to what some have speculated, this phenomenon wasn't caused by quality control issues because we can show the same power supply to two people at the same time and elicit different responses. Rather it was our intention to deliver top dynamic loading performance that produced noises some of our customers consider unacceptable. If you are a current user of our Olympia/Decathlon 650W ~ 850W power supply and you do not hear the noise mentioned by other, it is likely that your ears simply cannot pick up on the frequency emitted or your PC has other noises that are louder (some 680i motherboards and 8800GTX cards have high pitch noises as well).

I hope this clear up questions that some of you may have of our Olympia/Decathlon 650W ~ 850W power supplies. I will post version numbers that will help to identify the original models and the revised ones in a few days.

Guys, may i know how much is the SS PSU OP650? and where can i buy it?

TY.

enlight also branded chapalang psu like aku comel and power logic ah?

if 26A per rail is considered just okay, what about all those high quality quad rail psu like FSP epsilon? epsilon cannot power up a 8800GTX?

I would like to know whether it is good to have OP1000 for my PC?

Im planning to take 8800 Ultra sometime later.

nobody tried Enhance PSU before??
i believe it's on par with Silverstone

Chow.

Its a reliable PSU, but the price is like a chapalang one  ..should be ok for a moderate rig like a 3800 X2 with 8500G even with some mild overclocking..but if running anything better than that better to get one of the really good ones..

Power logic & icute are chapalang for sure, but better than the average "made by Sdn. Bhd" chapalang PSU. At least it regulates ok at low load, and won't 'letup' immediately (but eventuall it will). I should get a 2nd hand one and test it out on an electronic load..hmm..wonder how long they'll last before going bang? The usual "made by Sdn. Bhd" and  "made by some unknown China small company) can only tahan half hour at 250W even though the thing says 450W...lol....those jokers are still somewhere in my house..burnt smell still got...

ok.. thanks for info...

this is about my friend rig:
X2 3600+ with stock hsf
cheap gpu(iinm 6200)
1 dvdwriter
1 IDE hdd
Enermax 350W truepower FMAII.
and mine:
X2 3600+ with stock hsf (mild oc)
8500GT
1 dvdwriter
2 hdd
1 audigy pci
few casing fans.
Enermax 400W Liberty
For both rig, is it enough for long run?

Yeap no problem running at all , FYI newer dual core processor like C2D and AMD X2 are quite power efficient compare to older technologies

OCZ acquires PCPnC

Wonder if PCPnC product that will be branded as OCZ.. will be sold a bit cheaper?
