Intel DH67BL Board
Cooler master extreme power plus 600w

I m on a plan to buy new graphic card probably HD 6670 or HD 6750 or GTS 450.

Please correct me if i am going wrong some where?

Max power required for 6670 is 65 watts and 6750 requires 85 watts as per the specification.Cooler master extreme power plus 600w has 2 x 12v rail with 18A+18A .So, with single rail connected to motherboard, i get 18x12=216watts. From the specification Cooler master extreme power plus 600w is 70% efficient. If so, then 70% of 216watt = 151watt. I5 2500k needs 95watt as per specification which leaves 56watt* for GPU. Will this be sufficient to support HD 6670 or HD 6750?

In case of GTS 450, after a search in google i found it has pcie 6 pin connector. So independent power input can be connected direct from PSU, by which card can get around 75 watts. So 75+56*(remaining from 12v rail)=131 watts but max power used by GTS 450 is 106watts.

To my understanding i hope GTS 450 can work with my PSU. But in many forum i see people using HD 6670 , HD 6750 or higher card with Cooler master extreme power plus 600w.how they are using it?

I never had any experience with graphic cards so far, i like know more about pcie 6 pin connector on latest graphic cards ?

I connected one 12v with motherboard and another 12v rail hanging useless. Is there is way to make use of the unused 12v rail with 18A ? So that i get 18A+18A=36A.

Since this is my 2 month old rig i cannot go for a new PSU. So which card should i choose?



 

here's the cm extreme power plus review:
http://www.hardwaresecrets.com/article/Cooler-Master-eXtreme-Power-Plus-600-W-Power-Supply-Review/1034
Why manufacturers like Cooler Master are still carrying power supplies with fake wattages is a mystery to us. We know that this is a very low-end power supply, but this doesn’t give the manufacturer the right to lie. This unit should be labeled as a 450 W unit and sold for half of its price. Being labeled as a 600 W product and sold for USD 70, it is a complete rip-off.

If you pull more than 450 W from this product, it will offer real risk to your computer, plus it provides poor efficiency, between 69.2% and 77.6%.
also using the 2500k with h67 didn't make much sense..
psus like corsair cx 500 v2 or seasonic 520w s12ii or antec neo eco 520c would be much better than the coolermaster psu. lower quality psus age faster.
gtx 560 would be better than the 6770 for gaming.

I am using a cooler master GX 650 with Rad 6850. You can go for HD 6670 or HD 6750, it wont be a problem, but if you planning to CX later, then you obviously should upgrade your PSU too

your cooler master GX 650 has 52A on your 12v rail so you won't be having any issues with 6850 by in my case extreme power plus has only 18A.
Is 18A on 12v is good enough to run 6750 or GTS 450?

When i buy I didnt know that cooler master extreme power plus 600w was a crap unit. When I build my rig, I planned the graphic card for future. I know I cannot overclock 2500k with h67 but still i can use intel HD3000 which is euivalent to 9400GT, till i buy new graphic card.
 

if you don't push your parts to their limits, then a 6570/6670 should be okay (for gaming at 1366x768 res). the caution about cm extreme power plus psu still stands. it should be replaced with a better psu for system longevity and reliability.
you can try using this psu calculator to estimate how many watts your pc might use on load such as gaming:

yeah dual 18A, but what is the point in having dual 18A? how to make use of it?

I can connect only one 12V rail to motherboard other will be hanging useless So, will i get more amps on 12v rail connected to mobo like 25 to 30amps?

how about GTS 450 !! can my PSU support it? it has external PCIe connection and i can get more amp from the 6 pin connector.

So, are you saying in 12V rail more than 18A is supplied, as the other rail is not used?
