Selection of PSU's by company is not a good idea.

Also, advice about brands should be taken with a few pounds of salt :). Which of the following do you think is true ?

Antec makes crappy PSU's
Antec makes good PSU's
Antec makes very good PSU's
Antec makes great PSU's

The answer .... all of the above. Manufacturer's are in business to make money ... the more they sell the more they make. Targeting a single market segment limits the number of customers you can sell to, limiting the amount of sales. So most vendors sell to multiple market segments:

Great PSU's

+1 to Seasonic. They produce VERY good PSUs and are worth every penny they cost. With PSUs, you definitely get what you pay for and Seasonics are some of the very best available.
 


There are many quality power supplies out there but it would help to know how much power you need. Some of the top performers comes from Antec, Seasonic, Corsair, Enermax. If you really want a good power supply, look at the particular model, not necessarily the manufacturer. Reason being is that most PSU's are not actually built by the company selling them. For instance, some of the top quality units from Antec and Corsair are actually manufactured by Seasonic. Here's an article to check out, but your needs may be more modest than these gaming PSU's:

As far as the TIM goes, I have always used Arctic Silver V with great results. There are other brands you can pay a little more for diamond powder or whatnot but I don't know that you'll find too much stuff that works better than AS5. However, the cure time for AS5 is about 2 weeks so if you'd rather have cooling efficiency faster than you may wish to look at other options.

Crappy PSU's
NP-650 http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story4&reid=117
TPT-650 http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story4&reid=1
TP2-550 http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story2&reid=22

So where you want to be looking is not what brand but what "line".

1st tier readily available PSU's:
Antec SG series
Antec CP Series
Corsair HX Series
Corsair AX Series
Seasonic X Series
XFX Black Edition Series

2nd tier, readily available PSU's
Antec HCP Series
Antec HCG Series
Antec TP New Series
Antec TPQ Series
Corsair TX Series
XFX Core Edition Series

As for Coolers, before ya go taking any particular web site's stats as gospel, check out their test system. Is it based upon an old outdated CPU technology ? For example:

http://www.frostytech.com/testmethod_mk2.cfm

FrostyTech's Mk.II Platform delivers a 150W and 85W heat load to socket 775 compatible Intel Pentium 4/D/Extreme Edition, Celeron, Core 2 Duo & Core 2 Quad class heatsinks by way of a 30mm x 30mm copper interface die.

Are you building a system w/ a LGA 775 CPU ? If so, you found a good site ....if not move on.

As for TIM's ..... AS5 does indeed have very good thermal performance .... in fact the only TIM that matches that performance is Shin Etsu's 751. However, AS5's web sit states that it takes 200 hours of curing time plus a unspecified number of thermal cycles. Those thermal cycles, according to at least one reviewer, take up to a year under "normal conditions".

http://benchmarkreviews.com/index.php?option=com_content&task=view&id=138&Itemid=62&limit=1&limitstart=5

So by my estimation of this statement it would take almost a year of normal use to properly cure the AS5 compound, or almost nine days of continuous power cycles to meet their recommendation.

My approach is, skip the curing issues and just go with Shin Etsu.

Here's the top 5 (lower is better)

http://benchmarkreviews.com/index.php?option=com_content&task=view&id=150&Itemid=62&limit=1&limitstart=12

Tuniq TX-3 (0) Aluminum Oxide Moderate 37.65°C A+
Gelid GC-Extreme (0) Aluminum Oxide Low / Thin 37.65°C A+
Thermaltake Grease A2150 (4) Polysynthetic Silver Low / Thin 37.65°C A+
Arctic Silver 5 Polysynthetic Thermal Compound (4) Polysynthetic Silver Low / Thin 37.55°C A+
Shin-Etsu MicroSi G751 (0) Aluminum Oxide Moderate 37.55°C A+

The following brands I would mostly recommend, although there are a few exceptions within their lineups (primarily their cheapest models):

■Antec
■Enermax
■SeaSonic
■Corsair
■Cooler Master
■Thermaltake
■NZXT

^+100....

Seasonic and CWT makes most of the actual physical PSU listed above but they are sold under the company's name. I would go with Seasonic and Corsair as the top two brands for sell... IMO

Thanks all for the replies I would be upgrading my cpu by adding a hdd and graphic card so the config would be

Intel quad core 3.0,4 gb ddr2,2 sata hdd(one 1 tb and one 500 gb),2 dvd writers,1 gb nvidia graphic card
 
If you prefer to stick with a single video card setup then you won't need anything more than a quality 650 watt PSU.. On that note my recommendation would be the either of the Corsair TX 650 V2, Antec EA-650, CM Silent Pro M600 (may generate debates) and Seasonic S12II 620..
 

But Wattage means nothing if the combined DC output current on the +12 Volt rail(s) is insufficient to meet the demands of the graphics cards and the rest of the components in the system, so that chart is missing one of the most critical specs.
