how much power to supply 2 2TB hdd?

check ur bios, if +12v lower than 12v consider overload.

try unplug hdd check again, if still under 12v possible PSU under power.

+12v rails are the most important 1s....it'll determine the PSU's actual truepower

It is normal for some PSU to supply 11.8v as well. There is a range of tolerance +/- which won't have any problem at all.

1TB and 2TB different in power consumption could differ a few W only.

While HDD won't be spinning full all the time, in ordinary usage.

Especially for storage purpose one, mostly at idle stage.

so the chaplang rm50 psu can support?

I would recommend you to invest on a better PSU in any case possible

It depends on what system are you running, in my case Intel Atom I use AVF 450W (RM60), for Core 2/i better get pure power supply or slightly better one if you can afford (usually around RM200).

Get a reasonable PSU.
Vantec ION2+ 460w @ RM150 is a rather good buy and its components is at a rather decent quality as well.

RM50 PSU doesn't meant can't support... but if anything goes wrong and it decides to pull your system down to hell with it, then its game over.

i see.
actually i got one cpu,plan to put in 2 2tb hdd..but im worried my chaplang psu cannot supply.
aik..
well,i think have to spend big buck liao...plan to upgrade next month..crazy..

I've lost a hard disk to a bad PSU. It wasn't a hard decision to spend a little more on the PSU after that.

Have u guys being try on 1TB WD Caviar Green before? Is that i'm the luckier guy or what, because I found that the HDD will become slow and slow and lastly even format need to take up to 1-2hours for only content Win OS data......

For the size of 1TB, if format entire HDD (not quick format type), surely take a few hours to complete.

u did use quick format or not?

as cherroy said, yes, it do takes time to format if u use normal format.

Sometimes it can be up for a couple of hours

Which hdd should i buy ?? WD Black or Samsung F3

Which HDD suitable for installing OS for budget less than rm350? Samsung? Caviar? Seagate?

Hmm.... I don't think so.....
First time using quick format with install WinXP is take up to 50min

Within week by week, i become slow and slow via copy, paste document or install software......

And 1 month later.... it totally become like a snail.... -.-"

So I try repair the window.... but resulting failed.... because it will to copy WinXP file into the HDD....

So I use up about 2 hours.. to format....

If as you said..... 1 TB need that much time..... then 2 TB sure need double of the time

For the HDD.... I had warranty for a new unit but haven't use it because I already install 160GB Caviar Blue....

As I gone through few website.... they had stated that Caviar Green have many problem.

Now is the time to backup , u try to test it by use software

Hi, may you share the WD Green 1TB model? is it 64MB?

I think you get the "advanced format" of 1TB which is not compatible with XP.

Quick format, don't need 50 min.

It's soooo true..happen to me..before this, noob about PSU..
After change to a quality PSU, no more hard disk kaput..
