I was hoping for suggestiong about which power suuple should I choose? here are the PC specs: Q6600/E8500 (overclocked) 9800GTX VIDEO WD2500aaks HDD some kind of dvd burner gigabyte p35 ds3r MOBO (not sure yet,p35 100%) mushkin 2x2gb cl4 RAM some kind of cpu cooling cpu overclock (nothing too extreme) case with 2/3 12cm fans
Here is what I think is suitable (I saw reviews of the vid card with more extreme processors use about 350W of power under load so I think 500W is enough): OCZ StealthXStream 500W Thermaltake TR2 W0093R 500W Thermaltake W0101RU 550W Cooler Master eXtreme Power 500W NZXT PP500W SeaSonic SS-500ET-APFC-F3 500W FSP BlueStorm II 500W Antec EarthWatts 500W SilverStone Strider 500W PC C&C silencer 470W
Thanks in advance!

CoolerMaster and NZXT are on tier-5 ("Do not buy" ) on the list that rodney linked. Of the ones you listed, I would probably choose Seasonic if the budget allows. Esit: second choice would be OCZ.

So what the verdict? edit: I have added the FSp blustorm 2 - Is sub 500W power supply will do? (say enermax noisetaker2 420W, or any other suggestions you might have)

With your computer, not being able to spend $100 a good psu is sad. I would go for the PC P&C 610W, A Seasonic no less than 550W, a Corsair no less than 550W, or a Antec NeoPower no less than 550W. Then again, there is much more than goes into selecting a power supply than just looking at what components you have. How long you want to keep the computer, how much upgrading you are going to do, how long you will have your computer on everyday, etc.
What is important is the amps that the psu can reliably deliver on the 12v rails, not the watts. It is recommended that a pc with a single 8800gt/gts have a psu with 26a, and a 8800GTX 30a on the 12v rails. I expect the 9800gtx to be in between.
Lower quality psu vendors up the watts for marketing by either delivering them on the 3v and 5v rails which is easy, but not useful. They also claim peak watts and at 25c instead of a more realist temperature. Lower quality units will also operate at lower efficiency.
The 9800gtx requires two pci-e connectors. One indicator of a psu that can handle your 9800gtx is if it comes with two pci-e connectors.
Of the units you listed, I think the FSP unit is the best value, or even the seasonic based on their reputation as a quality primary manufacturer.
A psu is not the place to go cheap with a nice system such as yours. The PC P&C silencer610 would be appropriate. A lower, second choice would be corsair or seasonic m-12 or s-12..
It would be better to save $50 on the case instead of the psu.

First of all , thanks alot for your reply , its just that im a first time builder and I left the PSU and case for last , so thats the situation. Im not sure about the power requirement for a system as I wrote , so I kinda guessed. I will take your comment into consideration and look further for PSU. EDIT: the PC P&C silencer610 is too expensive (do remember I live outside of the US, and prices are diffrent) but the 470W model is about right.Ill add more later. EDIT2:Antec EarthWatts500W fits in my budget , what is your take on it? EDIT3:SilverStone Strider 500W also fits , your opinion?

Get a Q6600 instead of a Q9450, there now you have +$100 to add to the budget without harming performance. Unless you are going to be doing some serious encoding with this computer, theres not much reason to get a SSE4 processor over one that only does SSE3. You still need to tell us probably the two most important things: How long you plan on keeping the power supply? and how often it is on per day (24/7?)?
NOT 24/7 except maybe a few night of downloading etc.
I plan to keep as long as I see fit - I dont know exactly when im going to upgrade or change the whole thing again , but at least 2 years.

Wow, no, not even close. The reason he would pay extra for the Q9450 is that the Q9450 is supposed to perform on the level of a dual core CPU in games. That is why I want one, that is why it is worth the money.
Antec earthwatts 500W is a good unit and has more amps on the 12volt rail (total 34) than PC Power and Cooling 470 which has 26amps
No, not even close. You can NOT just add the Amperage, it does not work that way. The Antec has an actual Amperage of 24A, the PC P&C has 32A. The PC P&C has an insane amount of Amps for a 470w or even a 500w, it is the only one I would trust to run that system.
I guess that was just my opinion. I would pass on something that really isn't worth its cost for what I am doing; especially if its causing me to believe that a power supply is an accessory for a computer.
The power supply is the most crucial part of a system, no matter how many cores, or how many GPUs you have they will suck if they are not being powered.

Well I don't think that is right. Let me do the math and see if I'm just doing it wrong.
Formula: Watts (W)/Voltage (12V) = Amps (A)
Antec Earthwatts 500w PSU:
If you read the sticker, it says 12v1, 12v2 MAX load is 408 watts.
http://www.newegg.com/Product/Show [...] wer+Supply so inputting the values into the equation you get:
408w/12v=......34Amps!!! Now this sticker does fall under the "just add them up" syndrome. Your right that "MOST" PSU stickers don't label the same way.
I'll throw in another PSU to show you differences.
Enermax Liberty PSU, shows clearly that it only can produce 36A on the combined 12V rails or 432w/12V=36Amps!
I don't disagree that PCP&C makes good PSU's, but I'd double check your calculations next time.
For the best value, I'd go with the Corsair vx550w PSU. It has 41A on the 12V rail and comes with a 5 yr warranty which none of the ones listed have that. It is also cheaper (after MIR) than the ones listed.
Corsair VX 550W ATX Power Supply - CMPSU-550VX

Thats the problem , I DONT live in the US , and the corsair is considerably more costly here. And again I ask: Which is the best of the three? -SilverStone Strider ST50F 500W -Antec EarthWatts 500W -PC P&C Silencer 470W

Interesting, but I will trust ANTEC to give me the information on an ANTEC power supply. The truth is, I emailed them and as always the tech support was great, and they said that in fact the Antec Earthwatt runs off of 32A for 12v rail, which is the same as the PC P&C. This brings me back to my original point, Antec is an ok PSU manufacturer, PC P&C is one of, if not the, best PSU manufacturer on the market.
I came to a conclusion - I wont be buying the Q9450 for several reasons.
My choices are now Q6600/E8500 , Im leaning toward the E8500 because
my main uses will be gaming , and overclocking is easier on a dual core.
With that in mind , should I change my choice for the PSU or leave it at that?
So 26A on the PCP&C is more than 34A on the Antec? I guess that the 26A is better? PCP&C makes good PSU's but Antec does so too. I'm just pointing out that 26A doesn't beat 34A of power. The PCP&C has a 5 yr warranty and the Antec only has 1 yr warranty, so that is the difference maker in that category. I wouldn't buy a 26A PSU for the proposed build, especially since most newer GPU's are requireing about 26-30A of power. This will limit OC'ing and future upgrades. The OP can buy it, but I'd try and get something with more amps on the 12V rail.
Just got back to this thread. Thanks lunyone for putting the b-raven right on the amps. I would never have posted what I did with out doing the research and looked up all the psu listed by OP and picked the one with the best rating/price ratio not because I like the brand name.
To OP your power requirements under heavy gaming are right up there what that PC Power and Cooling can deliver constantly on the +12V rail.
Antec only has 1 yr warranty,

The Antec warranty is 3 years.
Definitely need to go for higher amperage.

http://www.tomshardware.com/2008/0 [...] age12.html According to Toms own review the power consumption of the 9800gtx under load is 265watts = 22 amps that leaves 4 amps for the rest of the system under constant use.
Yeah, but if you have the system for a few years and add a more power hungry GPU (9800gx2) you will be pushing things. I'm not saying that it will work, but with capacitor aging you could run into problems. It's nice to have a little extra now, so you don't have to upgrade in a year or two. Just wanted to point that out. The OP can go with whatever he feels comfortable with, but thought I should mention my concerns/opinion.
