Newer systems[mobos] haf 24 pin power connector. That is it has a 4pin extra part attached to da 20 pin part. This extra power is mainly driven to PCIEx16 slot.
Most PCIE version of cards dun need extra power where the same AGP card need extra power. So the system can atleast run with a 20 pin, but never if u use any gcard[be it da lowest 6200].
i think 17A is da min for 8600GT. It shud work, but might get unstable at peak loads or at time of GPU overclock.
There are cheap 400W PSU with upto 22A on 12v rail. It makes more sense to get max rating on 12v rail. Lil lower rating on other rails dun affect da stability much.
Why take chances, get da Zebronics 400W. Its also cheap nd is very easily available nd has proven stable by assasin. Actually me too was running my rig on dat for 1yr. I upgraded to Platinum mainly for bling bling.
Another factor for selecting gud PSU is da weight. The more weight it has greater is da chance dat its stable. More weight means bigger nd higher rated transformers, so better power, and also weight can be due to larger heatsink for transformer, which also is gud. It cud give extra stability during higher temps.

many local PSU's are rated much higher like 24A for a 450W for 500/- bucks, but its sure the real power is no way near dat. For eg Intex PSU 400W has 22A. Its very small nd light as feather. We can see a tiny transformer sitting inside dat. At first look we can conclude its only haf of the rated power.
But as of my experience, zebbys [even low end] PSU delivers max efficiency of da class. That is a 20A zebby is better than a 22A Intex or others.
Costly PSUs has higher efficiencies. So even an Antec 300W with 17A on 12v is much better than Zebby 400W. But Antec 300W wud cost more than twice of da zebby.

Frontech 550W is gud. Its for 650/-. It has 6 molex connectors and a sata connector and is 24pin.It has 4 pin nd a six pin PCIE power connector for gcard also. Its much heavier than Zeb nd we can see a huge transformer+heatsink inside it. It has junk of cables nd connectors.
Is gas some 25A written on it, and im sure it cud deliver more than Zebby 400W model.

thanks . i cudnt find that zeeby 400W u mentioned . i saw on teh website that zebby 400W with 20A on 12volt has 20 pins , so is it OK ?
i'll search again .if i can find frontech , i'll grab it . .
and hey , dudes , help the OP too !!! We got solutions for our problems , but wat abt the OP ? neway , thanks a lot for answering me . i'll search tomorrow and get back to u.
ok . finally found a zebby 400W psu with 20+4 pin and 20A on 12volt rail . cost 500 bucks . shall i buy it ? will it b enough as my p4 generates more heat and thus draws more power than a c2d .
i dont want to simply throw away 500 bucks . if it wont b enough ( and pc keeps getting off while playing games ) , i might as well go4 a psu around 2k . but i dont have that much money , so that'll b difficult .
If u guys say that the zebby is enough for me , i'll buy it .if not , i'll wait for sometime so that i can pile up enough pocket money and get a better psu . wat shall i do ?

no , i wont add a 8800 . in 2 yrs or 3 yrs , i'll go4 full pc change and next time i'll make sure i get a good psu . . now i dont have that much cash . if u're sure the zebby psu will b enough i'll go4 it .
if its doubtful whether that psu is good enough , then i'll wait for 2-3 months and get a better psu ( i dont want this option ).
so by ur post , i infer that i make no mistake in buying that zebby psu . so , i'll go4 it. i'll buy it tomorrow , plz confirm whether my decission is rite or if i shud wait.
thanks a lot , i owe u one.

man , dad aint agreeing at all . he says , me opening the cabby is causing all problems !!!!so i cant buy that zebby smps from even my pocket money !!
this may turn good and if the vendor says a 2k smps is needed , my dad will agree , but on the other hand , he might place a stupid smps again . . .
A Strange twist of events indeed. watever i get , i'll come back to u.

hehehehe , i wud have done that if i had the link . but read it too long back ( 4 months maybe ) . so u search , y shud i ?
i think title name is PCI scaling analysis or something like that.
for 8800GTS , 5000 3d marks on pciex4 and 6k and odd for pciex16 . u can expect 10-20% loss in performance .
