hi,so i have this card -http://www.newegg.com/Product/Product.aspx?Item=N82E168...

my psu is this -http://www.mediadot.ro/surse/sursa-inter-tech-booster-5 no 6pin cable

so i have this 2x4pin molex to 6pin pcie -http://www.megaware.com.au/ebayimages/2molexto6pin.jpg

and i have only two spare 4pin molex from my psu and i want to use this fan silencer too -http://www.electronics.balticmart.eu/uploads/Products/1...

QUESTION - CAN I CONNECT THIS FAN SILENCER TO ONE OF THE 4PIN MOLEX CABLE WHICH WILL GO ALSO TO MY GPU ???(FAN SILENCER HAS SPLITTER TO ANOTHER 4PIN AS YOU CAN SEE) DO FAN WONT MESS UP THE POWER RAIL TO GPU ???

pls tell me......

The link for the PSU is broken.
But as long as the PSU is 500W or greater, then everthing should be fine, becasue the GTS250 requires at least 450W PSU.
Also if the PSU has the SATA power connection you can get this too, "8-inch SATA 15pin to 6pin PCI Express Card Power Cable"

Or the Y Power Splitter. http://www.newegg.com/Product/Product.aspx?Item=N82E168...


thnx for reply ,really needed my third thread with this question atleast third time i got an answer the psu is cheap max 520w you can see specs under second tab "specifikacija" http://www.skytech.lt/itsps520w-power-supply-intertech-...

but i heard tha splitting power to gpu si not very safe and it requeres two 4 pin molex ,btw how adding this fan silencer to same one of the 4pin molex rails would effect power drawn to gou ?? i heard amps really matter...
a need an answer from someone who knows alot about psu wattages,amps and its effects like in my case...

It don't look like the good PSU because it only has 2x 4pin mole + 3X SATA, and it does not list the efficiency. Becasue the good PSU will have at least 80% efficiency. I look at the website I found the one is good that costs a lot more (OCZ-CXS500W-EU).
In other hand if you connect the Y Splitter to GPU is not safety, but you can connect the 6pin into the one from the Splitter + one from PSU. And the fan silencer can connect to the other head of the Splitter.

so fans wont change amps on gpu rail negatively? some guy in pc tech chat said it's not safe... some other guy said fans wont eat up mutch power but amps matter too not just watts
March 23, 2013 10:47:00 AM

Yes, 1) fans wont eat up much power, 2) amps is related to the watts, like amps x volts = watts. And I can't find the same model GPU, but I found other brand BFG GTS250, it need 26A on the +12V rail.

When you look at your PSU specifications: +3.3V 24 A, +5V 20 A, +12V1 18 A, +12V2 18 A, -12V 0.3 A, +5VSB 2.5 A. watts output 520W.

When you add the +12V rails 12V X 36A=432W, and only other +5V rail 5V x 20A=100W, only both is already more than 520W. If we add up all the number and the total watts will be more than 620W. So if the PSU can output 520W like they say, then +12V rail has 29A. But I don't count on that 520W.

mine gpu needs 450w psu and 12v rail with 24a ,yes psu is cheap one... so your final conclusion ???

so your final conclusion ??? is my psu enaugh to handle it safe >>????

You can try it out. But watch out the PSU, because if it works too hard, it can burn then that maybe cause other problem.
I will recommend to get the good PSU.

ok i will try monitor psu voltages and see with hand how hot it is ,and i replaced one 12v stock psu fan with two same but 7v fans one fan pushes air in other blows out i guess still more efficent than only one 12v which pushes in only,cant afford good psu 80plus quality, maybe in future same brand but with more amps and cables ,plus better cooling --http://www.skytech.lt/itsp53012cm-power-supply-intertec...

so today i tryed to connect this gpu like this,it ran fine,voltages droped to 11,40v lowest on loads,but after few hours of gaming now in game when its under load it emits some weird buzzing sound ,and when i press escape it immideately stops i guess psu is too weak for this,maybe it,s psu capatitor sound cant really tell..... and runs hoter than before but not dat hot to touch ....
