Hi all,
I have been seeing posts & threads asking for which PSU to buy for their systems. Well, I have got some information I wanted to share regarding this so you make a good choice in choosing the PSU since it is the heart of any configuration.
Make sure you choose the best ones else you would have to repent or pay more for buying a new one including other parts which have been destroyed by your cheap old PSU
.
The following link is from Xtreme Systems forum. Though the link has not been updated with the latest ones, it still provides a very good information for the selection of the PSUs. The list has been compiled by a Xtreme Systems forum member named
perkam. Thanks to perkam for the list.
Official XS Tiered PSU Manufacturer Brand Listing Phase III
http://www.xtremesystems.org/forums/showthread.php?t=108088
Here is the main info from that site :
------------------------------------------------------------------------
WHICH ONES TO BUY ??
Tier 1 can handle 4Ghz Conroe or 3Ghz AMD along with Oced Quad Crossfire/SLI With Ease.
Tier Z offers quality and power unequalled in its wattage range and is second only to other Zippy units.
Tier 2 offers almost as much power and stability as Tier 1 at Comparable Wattage levels with lower price/better availability.
Tier T offers the high quality components of Tier 2 with slightly less Rail stability due to Topower internals.
Tier 3 is ONLY Recommended if Price difference is present between Tier 3 and Tier 2 or due to availability issues with Tier 1/2 PSUs.
Tier 4 is recommended for stock or low power systems if Tier 3's are more expensive or are not available.
Tier 5 are NOT RECOMMENDED, but some brands have high/medium quality components in Tiers 2 through 4.

Phase III compensates for overcrowded Tier 1, while clumping together previously Tier 2 and 3 PSUs if only because no definite way to categorize then as good enough for Tier 2 or bad enough for Tier 3.

Hopefully this will sort out most of the issues regarding which ones you need to buy for a specific configuration.
I have also noticed this :
Many of the threads (not all) which have been made Sticky are going beyond 50 pages
. Who will have the patience to read all the 50 pages to get the whole information ? I request the MODS to close the Threads which they have made it sticky whenever it is appropriate.
For example: this thread "Basic Guide Purchase a New System" is now reaching 52 pages. But the most basic & valuable information comes in the 1st page. Other than that, the rest is useless
.
So MODS please close the sticky threads wherever/whenever it is appropriate. 
I hope the MODS do mine when it is made a sticky.
NOTE: Some of the brands listed above may not be available in India though. But from my R&D, I have found that most of the well known PSU manufacturers like Antec, Cooler Master, Corsair, Thermaltake, Enermax (to name a few) are available.
