Understanding Power Supplies...

[HolySlayer]

well... I am confused about the power supplies and stuff... I have several questions lined up about PSUs.

* If I am going for a Quad Core processor, is there any physical difference of the sockets for that?

* Since I am hoping to get a 4850, would I need any wires/cables/sockets/converters for its power?

* The recommendations I hear from most people about wattage for certain components (Processor+GPU) are those mostly guesses or have basis? Like in UCC the other day I asked abt how much I'd need for a Q6600 + 4850. The guy said u'll need at least a 700W toughpower something. When I said I 'wont' spend huge chunks of my budget after that, he recommended a 420W psu. After this, I am quite convinced they know sh!t about 'actual' wattage requirement and more about selling their goods...

* In Thermaltake's website, they use this tool http://www.thermaltake.outervision.com/Power
to calculate wattage. I used it to calculate my requirement for the components that I might get... it shows surprizingly low wattage requirements... (270W @ peak with Q6600+4850)

Is this calculator thing wrong? Or evbuddy staying in safeside and buying more powerful PSUs than their requirements?

Prolly I really need to go to school for this...

Well when u talk abt psu efficiency should come into mind.. if a psu says it will supply 420 watts it might mean that it will provide 420W at its peak performance.. so it rilli doesnt provide 420w at normal operation.. like thermaltake has more efficient psu than delux or anything

well about efficiency, thermaltake's site also says that the higher the wattage of a psu higher the efficiency... but i have budget constraints, which will not make me buy a huge power/price PSU... what do i do?

Space er PSU kemon? i asked a guy from shop in IDB (beside UCC which is not smart)... they have 400W PSUs @ 1500-2000tk and 600W @ around 3000tk... are those good?
