Thanks Jaskanwar Singh for your reply. Have never used AMD, would it be better than Intel E Series Processor like E7500 or Core i3?

Can I opt for Core i3 for using with Win XP SP3?

What would be a better choice MSI or Gigabyte? Do MSI MB's have GIGABYTE On/Off Charge type technology (for USB charging)?

How much would be the cost of CM 690 II? Also, what other options can I have with CM cabinets?

AMD is the best option for u now
AMD masters in value for money components
and it fits in ur budget
go for it....almost all of the members are using AMD now and are totally satisfied with it

u can go for sp3 anyday

MSI/Giga are better choices now-a-days
yes the latest boards do have this on-off USB charging technology

Thanks piyush120290 for your reply. 15-20k budget is without LCD.

Should I be going in for FSP Saga instead of the CM fitted PSU?

Also, can you advise on any other CM cabinet within 2k?

How much would a Intel Core i3 config fall around?
Piyush
Piyush #6
Oct 19, 2010 at 9:50 PM
ok ..listen bro
we can make an intel i3 rig within this budget
but AMD offers 4cores instead of 2 cores (intel) at the same price range
with AMd u r rig be more future proof
trust me

even if u wanna give i3 a chance ,then jas will be able to give u a better i3 config than me

and regarding cabinet
u can go for
CM elite 310/335 (low budget) both available at 1.5k
CM elite 430 @ 2.6k (the best deal for u)

and go for FSP saga instead of pre-fitted PSUs as they are not dependable and do remember one thing:
stay away from CM extreme series

Which GIGA mobo would be advisable with this AMD processor?
Piyush
Piyush #8
Oct 19, 2010 at 10:07 PM
take the mobo which is mentioned in jas's signature
if thats not available,then look out for my signature

also go for gigabyte 460W superb @ 2k
and u can increase ur ram to 4gb

Oct 19, 2010 at 10:19 PM
Thanks for suggesting CM Elite 430. Looks really cool.

What would be the price range for your or jas's mobo?

Also, will this processor be fine for some gaming as well?

Or which would be the next AMD in line from AMD Athlon II x4 630?

What's the price range for Phenom II X4?

Thanks guys for all your support specially Jas as have gone for his config apart from minor upgrades. ;-)

But dint get the FSP Saga II, had to settle with CM 400W PSU. Here's the rig:

AMD Athlon II x4 635
GA-880GMA-UD2H (Combo @9.2k)
WD 1TB Carviar Green @2.8K
Kingston 2GB DDR3 1333 @ 1.9k

Total Cost: 18.7K

Howzat!!!

But one thing gone wrong this guy offered assembling & loading of Windows (My CD-XP SP3) for 200 Bugs. I got tempted & asked him to go ahead with three partitions of 200GB, 400GB & 400GB. Now when he has loaded the OS, the partitions are being shown as E:, F: & G: & the Removable Disk (which is the card reader) is being shown as C: Drive. :?:

Any advise where did we go wrong?

If you properly know how to just format your HDD using WinXP CD or WIN7 DVD and then create the partitions...if your DVD Drive is D then read note...

NOTE: You may have to unplug your card reader until you format your HDD...i guess the assembler might have inserted the card reader and the DVD Drive before the HDD...

See if that solves the prob..otherwise contact the assembler and ask him y he messed up???

Coz of short on time had to leave today, otherwise would have got the issue sorted by the man.

He inserted the HDD, then Card Reader & then DVD Drive and for the formatting & partitioning he did was fine. Now should I re-format the HDD with card reader unplugged or use Partition Manager as suggested by piyush 120290?

ok...I'm not sure partition manager can solve this prob as u'll be using your HDD while running the partition manager...In PM it will ask u to change drive letter but the options will be excluding C,D,E,F,G as they have already been used...so if the drive letter really annoys you then u'll have to Format your HDD...

that PSU has not more than 70% efficiency
so 70% of 400W is 280W
that means u cant use more than 280 W from this PSU
and that 70% is under certain temperatures readings
thats why

hey dont feel down
its OK until u dont do heavy upgrades

i calculated u wattage requirement
if we take ur PSU efficiency to be 70%
then ur output would be 280W

and ur setup requires 210W
so u are in the safe zone right now
u even van add a low end-less power hungry graphics card to ur PC
enjoy :)

baba you are completely wrong here..
that psu has 70% efficiency means that it will consume almost 571w from the wall socket to deliver 400w.

efficiency = output/input for anything.
output = 400w.
efficiency = 70% = 70/100
input = output/efficiency = (400/70)*100 = 571.

to be more specific here -
Efficiency = DC power / AC power

as psu converts ac power to dc power to supply to the pc.

also higher efficiency means less power draw from the wall and saving on electricity bills.suppose it had 80% efficiency. then it would have pulled 500w from the wall. also lower efficiency means more off the excess wattage being converted to heat. for eg. in your case - 571-400=171w is converted to heat. higher efficiency means cool system too.

also a psu is designed to deliver rated efficiency at a certain load. eg-corsair vx450w delivers 86% efficiency at 40-60% load on it.

This a known and common problem of windows Xp.
You have 3 workarounds to solve it :

1. Install Windows Vista or Win 7

2. Disconnect the card reader and install a fresh copy of windows XP and then reconnect the card reader after windows installation

3. proceed with normal windows installation - during the partition selection part of text-mode Setup delete all existing partition and create a new hard disk partition.

you may see the drive letter assigned to the primary hard disk partition is E or a letter that follows E.

Select the newly created partition and delete the partition.

Select the unpartitioned space again and then create a new primary hard disk partition.

now you can see the drive letter assigned to the primary hard disk partition is C but if the primary hard disk partition is not C the drive letter should be displayed correctly on the next system reboot.

BTW, congrats for your new rig.

For all devices:

Efficiency is ratio of : output / input.

Works the same for PSUs. Many guys confuse it with how much out it actually delivers. The crux is "how much power will the unit draw from the socket to deliver".

People may ask where the energy goes, will it is converted to heat and sound due to component resistance and various conversion losses.

Thanks guys for your replies & info. Finally was able to sort the problem of C: Drive yesterday by disconnecting the card reader & then formatting C: Drive & reloading XP SP3.

that psu has 70% efficiency means that it will consume almost 571w from the wall socket to deliver 400w.

efficiency = output/input for anything.
output = 400w.
efficiency = 70% = 70/100
input = output/efficiency = (400/70)*100 = 571.

Thanks topgear. I would have loved to install Windows 7, but since this is for my office; need XP SP3 for some softwares like Tally 7.2 etc.

When I removed the card reader & came to the disk partition option while installing XP, the partition were showing as C:, D: & E:. I just formatted the C: Drive & installed the OS. After installation attached the card reader to the mobo & it showed as Drive G:.

I hope it was okay not to format D: & E: drives. They are showing as un-formatted drives in the windows explorer. Will format them through Disk Management.

^^ that was the most simple way to correct the driver letter issue - glad to know that you've sorted it out - you are right - you now need to format D and E through Disk Management

BTW, if you need to re-fromat again someday with the card reader connected then use the method No. 3 I've described on the earlier post.

Have formatted the D & E through Disk Management. D: I did a normal format & since it being a 350GB partition it took about 70mins. Hence, quick formatted E: Drive which just took 5mins, hope its okay?

As far as the review is concerned - looks no gr8, but can't do much now.

@ ParryD - man - you really have a lot of patience - 70 mins to format a partition - what were you doing during that time ?

A quick format just removes the files from a partition but don't check that partition for bad sectors.

don't compare it with zero filling though and that's why you can get your data back after a regular/quick format - A zero filling writes zeros in every possible sector of disk and data recovery becomes somewhat impossible. You need to use some 3rd party app for that too.

A regular format checks the the partition for bad sectors as well - so it takes that much time. ( don't use it too much though )

Try to use quick format always and if you have some doubts about HDD use chkdsk /r command to check for bad sectors or use 3rd party programs like HDtune.

As your disk is new it's OK to use quick format.

I always have admired the easiness in Windows Bootable CD/DVDs for the procedures of hard disk partitioning :)
