rajan if asingh can run 4890 CF on TX650W why cant that psu hold those gfx cards.

 

[rajan1311]

fine then, 70% people run cards like 5670 on generic PSUs, then why recommend an FSP ? I dont say it will not run it, just saying its not wise recommending it. You might want to see guru3d recommendations..

[Jaskanwar Singh]

So u suggest the adjustment rajan

rajan buddy in the link you mentioned see the total 6850 CF with i7 965 full stress power consumption. its 393w. even 6870 CF system full load consumes 421w!!!

intel sandybridge prices and models

1. Intel® Core™ i7 2600 Processor - 3.4 GHz, 8 MB Cache, Socket 1155 with HT @ 15k
2 Intel® Core™ i5 2400 Processor - 3.1 GHz, 6 MB Cache, Socket 1155 without HT @ 9.9K
3. Intel® Core™ i5 2300 Processor - 2.8 GHz, 6 MB Cache, Socket 1155 without HT @9K

4.Intel® Desktop Board DH67CL ATX , Socket 1155 @ 8.9K
5.Intel® Desktop Board DH67BL uATX, Socket 1155 @ 7.9K

Check this

They claim to ship within 48hrs. The i7 2600 looks promising and may beat i7 950 fair and square but nothin can be concluded without a proper review.

@ Jas

Buddy i think you have to again edit the config prices as all cpu's have undergone a serious pricedrop.

Cilus will post the latest prices here.

 

[rajan1311]

yes jas, even then, i am saying it will work, but should not be recommend. A GTS 250 pulls a good 30W odd more than a 6850 at full load. I would get a good 650W PSU to safe. Just my thoughts...

@Vicky : thanks for those prices bro, but is the sandy bridge worth upgrading to?Any proper reviews out? It seems Overclocking is restricted in the i5s.

 

[topgear]

But the PSU should be chosen such the its around 50% load, this seems like a bad idea loading it up so much..

Would you run a 6850 CF system on that PSU ? No. GTS 250 consumes significantly more power than a 6850.....

I don't think so. If your total power consumption is say 350W would you buy a PSU which can deliver say 700-750W. It's better to keep it under 80-90% not 50%.

fine then, 70% people run cards like 5670 on generic PSUs, then why recommend an FSP ? I dont say it will not run it, just saying its not wise recommending it. You might want to see guru3d recommendations..

Radeon HD 6850 & 6870 CrossfireX review

We recommend FSP as it's build quality is better than any run of the mill generic PSU and the power distribution is clearly mentioned unlike those cheap generic local psus.

rajan if asingh can run 4890 CF on TX650W why cant that psu hold those gfx cards.

2x HD4890 can consume say = 370W - gpu only

His whole rig with other components consume say = 200W

TX650W can deliver : 624W

So u suggest the adjustment rajan

rajan buddy in the link you mentioned see the total 6850 CF with i7 965 full stress power consumption. its 393w. even 6870 CF system full load consumes 421w!!!

I think you've overlooked this :

The methodology: We have a device constantly monitoring the power draw from the PC. We simply stress the GPU, not the processor. The before and after wattage will tell us roughly how much power a graphics card is consuming under load.

two 6870 cards power consumption = ~ 275 Watts

so they are only stressing the GPUs not the cpu - add another say 200W and you will get some decent idea.

@Vicky : thanks for those prices bro, but is the sandy bridge worth upgrading to?Any proper reviews out? It seems Overclocking is restricted in the i5s.

Now the 1st phySX rig will consume :

Intel Core i5 760 - 100W
Sapphire HD6850 TOXIC - 120W
MSI GeForce N250GTS-2D512 150W

All other components 50W - so total : 420W and VX550W can deliver : 492W and it's under 90% load and I think it's safe enough.

BTW, all the mentioned wattage in here is just indications and actual power consumption may vary !

 

[rajan1311]

Well, generally efficiency is highest at loads near 50%, hence the PSU remains cooler and ensures a longer life. But at higher loads, efficiency drops off, heat increases and that could get you into trouble after some time. If a person already has a 550VX, then its find,but if he is getting a new rig, then why risk it?

 

[Jaskanwar Singh]

thanks for the correction topgear.

but replies on the rigs please. hows F&D speakers.? i added them because its got good rating in digit. what are your views?

@vickybat: as u said there is a price drop in cpu's. is it the lga 1366 processors? is there a price drop in i7 950 ?

also will there be price drop of i7 950 once sandy bridge launches? and will i7 950 be EOL product?

 

[vickybat]

^^

Well the bloomfields might reach EOL but gulftowns will remain top dog but until 6 and 8 core sandybridge is launched.

Well how you tracked the Power consumption and especially specifically for each item? Can you tell me how much mine do? Is there any way to know this?

Thanks anyway.

 

[topgear]

^^ your rig will consume around 300-320W - it's just a indication though - you will get a fair idea of power consumption by going here :
*extreme.outervision.com/PSUEngine
that will give you an fair idea but sometime you may have to do the calculation manually!

thanks for the correction topgear.

but replies on the rigs please. hows F&D speakers.? i added them because its got good rating in digit. what are your views?

I also read it on mag like you and they said it's a good brand - so I think you can suggest them.

Now about the configs : It would be great if you change the 100K phySX card from MSI GTS450 to Zotac GTS450 - it's cheaper by 1k and why should we pay more ? Even at stock speed GTS450 is more than capable to handle phySX only works.

If there's any other suggestion that comes up in mind - rest assured - I'll post them.

BTW, you are doing a great work - keep it up - I appreciate your efforts.

 

[Jaskanwar Singh]

thanks topgear.
i will change it to Zotac GTS450.

and some corrections on 170k and HTPC rigs please too.

 

[vickybat]

@ jaskanwar singh

Buddy i think you will now have to revise all configs with the advent of sandybridge processors. They are brilliant performers. Even in video encoding tasks they stand highly recommended. Check out the reviews.

 

[aby geek]

yup vicky is right ,thats why i was kinda confused why you started this thread before the launch.

so lets starting boycotting bloomfields ,on that i think jasji will need help with 1155 mobos.

lets get started.

and isnt 2600k launching on 5th?

 

[Jaskanwar Singh]

buddies let me read anandtech now. first time fully(inc. the first info pages and not the performance alone)

 

[ssb1551]

aby just hold your horses!!Jas will come up with new configs(Sandybridge CPU based rigs) in no time!!

@ Jas - Which GPU do you have?How is Black Ops & Civilisation 5?

 

[Jaskanwar Singh]

currently onboard HD4250 allows me to play black ops at 1366x768 with high texture quality. addicted to black ops.

some 1155 mobo list please.

 

[ssb1551]

Dude thats awesome!!That means I can play Black Ops on 4650 at the same resolution!!

 

[Jaskanwar Singh]

i have also oced hd4250. let me check again from how much to how much.

also 1366x768 is not full screen. at full screen 1366x768 the game struggles. but happy with not-full screen till i get a gpu.
