I dont know what you are pointing out here... but both of those are worth the hard drive space they are stored on... I worked on

Q6600
8800gtx
desktop mainboard
1x hdd
1x odd
mouse, keyboard
X-fi

The asus came back with 400W and the other one came in at like 310W ... there is no way in hell i would run an 8800gtx on anything less than 500W with some awesome 12v Rails.

I clicked on both. The first said "Service Unavailable" and the other was blocked with the description of malware as the reason. Do explain why you posted those.

Both still work for me lostandwansering... but they are usless.

The Asus one now comes up, but my school is still blocking the other one on the claim that it is malware and violating my usage policy. Strange.

Maybe you should lower browsers standards just a touch, keep in mind that those figures are minimum standards.
You might have a little malware running in the background, a quick scan would be wise.

Precisely, calculated figures are bare minimum ratings.
The sensible mind tells us that we need at least 25% headroom.

My system is very power hungry and topped the charts at 550W minimum, i compensated for my planned upgrade to the 6400+ with 2-1GB sticks @ 800MHz
I found it interesting that my current system configuration uses more power than my planned upgrade,
the 5200+ combined with 4-512KB @DDR2 800MHz uses 50W more.
I figured the faster processor would compensate for the missing RAM, at least the FSP 750W PSU will be happier.

So according to this, I need a 700 Watt PSU...
For a q6600, sli 8800 gts, 1 dvd, 5 fans, 2 hdd's, a sb xfi, and a few USB ports, etc.

Right now I have a core 2 e6750 and everything else listed above, and a 650Watt seasonic s12 80+...

ANyone with good experience want to tell me if this PSU is enough to run the q6600 in this config?

Is my 650 Watt PSU enough?

Case: Antec 900
PSU: OCZ 700watt
Board: P35 DS3R
CPU: Q6600 @ 3.00
CPU cooling : Zalman 9500 @ ~2200 rpms
Memory: 2x 1024MB ,2X 512MB @ 2.0 volts
Video: 8800GTX 600(core) 1400(shader) 900 x2(memory)
Storage:
2x WDC 250gig (Raid0)
2x Seagate 320gig(Storage)
2x Seagate 500gig(Storage)
Optical drive: Samsung SH-W162
TV card: PVR 250
Sound: Creative SB Audigy 2zs

Power usage :

Idle speed step 200 watts
Folding 250-280watts
Games under 350watts(last time I checked) with folding

PSU efficiency(manufacturers claims) 80%
350 - 20 %(for conversion/ect loss)
about 280watts of TOTAL* dc

* Majority of the power in my system is off the 12 volt lines either way the 600 watts asus told me i need was wrong....but it over estimates. this may be a good thing. a 8800GTX is supposed to take 132watts(or somewhere in that area). Asus puts down 150. They over rate some other items too.

In the end it all comes down to PSU quality. If i had a 450 watt psu with 25-30 amps of 12 it should run my system fine.

@ bornking - That psu specs 52 amps MAX of 12 volt power. can you confirm this? it should be good to go thats as much power as many 700 watt PSUs anyway. I am willing to bet if you got a kill-a-watt meter you would be surprised how much headroom you still have....

thank you for the good advice nukemaster.
I will continue to use this PSU even when I upgrade to a q6600.

If you can get a G0 stepping...do it they save some power too.

I ran your config on the eXtreme Power Supply Calculator Lite v2.5 I assumed high end board, 2 sticks DDR2, 5 120mm fans and 3 USB. With 100% cpu usage and no Capacitor aging I came up with 495W for the PS. With an OC to 3.0G @ 1.25V I got 510 watts.

That doesn't take into account sufficient amperage on the 12v rails. I don't know whether they are lying about the 18A limit on the 12V rails but they do make Corsair and at least the Silencer series for PC Power and Cooling, which are single rail (even though Corsair states they are multi-rail).

Here is a quote from jonnyguru on the Seasonic M12 700W
Quote:
Now on the previous page, you saw that Seasonic advertises this PSU as having four 12V rails. You'll notice in these load tests that I only specify a load on 12V1 and 12V2. This is because I could not find any proof that this PSU had more than two 12V rails; at the most three. And I found that even if there were three 12V rails, there is no OCP (over-current protection) or any circuitry in place that disrupts continuity between the multiple "rails." We'll discuss this further during the autopsy.
It's a different model but I would suspect that there are many similarities probably including the rail layout. Seasonic makes a quality PSU so I don't believe you will have any problem using you current Seasonic 650.

I don't find that ASUS calculator to be very good just playing with it.

Started with Intel Mobo - It said 50watts. A little High. OK we want head room I can live with that.

Added a Q6600 - It added 150w for a total of 200w. (The TDP is only 105w for the old Quads so that is a big overage.)

I added a 8600GTS - It added 0w. Odd?
Then I changed it to ann 8800. It now added 200 more.

Now the 8800 takes less than 200 itself and definately not a 200 difference between these two GPUs.

5 case fans = 0w.
10 case fans =50w.

It counds 50w for every (2) HDDs. 0w for the 1st. 50w for 2nd. 0w for 3rd. 100w for 4th.

GPU Reference for watts.

http://www.tomshardware.com/2007/08/21/energy-efficient...

Sample HDD for Watts - (Under 10w in use)(vs 25w averaged for chart)
http://www.hothardware.com/articles/Western_Digital_WD5...

Note: The Wattage for the CPUs was also well beyond the TDP by about 50%. You are talking a serious OC and volt increase to see these numbers.

I can understand wanting to overestimate, but failing to add anything for some items such as the 8600 or in other cases only counting multiples and adding big jumps just does not make sense. This causes the headroom to be lost.

Thank you ZOrg, I agree with you that my PSU is plenty.
I have an ASUS striker extreme (new) BTW.
And I will 'try' to get the G0 stepping but how do I tell from the box?
and yes 2 sticks of corsair twinmx2 1 gig at 800 mhz each.
I am a happy camper again.

the product code ends in SLACR on G0 Q6600's

Others end in SL9UM or something like that...

If you are buying online, a few places are promising the "G" stepping, so look around. NewEgg seems to be shipping that version, but not promising it so, you are taking a bit of a chance.

Here is how you ensure that you get a G0. Go here ClubIT Product - Intel Core 2 Quad Q6600 G0 Stepping

Good deal too.
