Well i did it! Got cent5 apart and polished the aluminium pieces, also painted the chassis Apple green...im so stoked...so i ordered another 7600gs...sli here i come. But as i was piecing thing back i relised how much of a mission my power supply is to keep neat then i began to FREAK OUT...OMG is my 420w Thermaltake powerfull enough for sli??? I got another gigabyte silent 7600 on order so they will be a matching pair, The card has no power connector or fan...i think they are pretty efficent cards??? but my board is 24 pin and the ps only 20 ...will i have power issues? its only mildly overclocked...what do you guys reckon? Thanks in advance. Craig.
