Posted October 7, 2016 hi just fitted a msi 750 ti lp gfx card into dell 3020 sff pc with 255w psu. heres how : 1. remove fan from msi 750ti lp card , this is the shortest of the 750ti cards and place in pcie x16 slot. now there is about 50mm sq x 25mm freespace behind the gfx card. 2. purchase an blower/extruder fan 50mmx50mmx20mm 12v by 0.12A or less and splice into power sata connector(yellow and black +12v). for the fan if three pin its red and black(+12v) and yellow is tacho and black negative on both. 3. some double sided tape to attach blower fan at back of gfx on the side of psu nb tips get fan blower hole about central to heatsink wedge between heatsink and psu a little to give more room for air flow 12v 0.12A fan creates 1.44W this psu has three rails 13A,14A,1.67A . I think these are peak values and not RMS values. I chose to splice into optical and hard drive power cable so I would not remove power from mobo for gfx card recent build still testing but appears ok , watch heat and adjust fan til best position. gfx at the mo is about 31c idle and 86c full load. that's running furmark which is the most intensive test software regards jools hope this helps someone and I am open to criticism and complements Link to comment Share on other sites More sharing options...
