Thanks Buddy, any issues with CM PSU 400W???

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

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.

@ op
congrats
i dont know much about software and all but AFAIK just reinstall the windows. choose your own partitions making windows as primary c partition.

man!!!!!!!!!!!!
and i thought it was this way
i was carrying this info for a long period of time
curse me!!!

and thanks a lot jassy
at least now i clearly know the scene out there about PSUs
thanks a million times bro............

ASUS Unveils the Bigger & Better - E.L.I.T.E. 2.0 Service for Motherboards

One guy got a new and much better USB3 mobo with full 3 years warranty in replacement for an older AMD motherboard.
Another guy was offered credit note of 7K (full refund i think) or a P7P55D (more expensive i think) mobo in replacement for an older socket 775 mobo.
These are just a few cases i have heard of.

^^ur help is on ur way ;)

yep and now here it is :cool:

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
LG H55N 22x DVD RW @ 0.85k
CM Elite 335+CM PSU 400W @ 3.3k
Internal Card Reader @ 0.15k
Internal Modem @ 0.25k
PCI I/O Card @ 0.25k

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?

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.

So whats your take/ review on the PSU I got installed.

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.

here's a review for your PSU

Thanks once again topgear for all the assistance.

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 :)
