Fitur VGA

Baik PowerColor X1950XTX & Sapphire X1950XTX mengunakan heatsink ukuran besar. Tetapi fan pada PowerColor X1950XTX & Sapphire X1950XTX sudah di disain lebih rendah noise dibanding X1900XTX sebelumnya. Panas VGA pada kondisi idle hanya mencapai 50 deg.C saja. Sedangkan ketika beroperasi penuh akan mencapai 60 deg. C untuk open case. Bila case memiliki disain air flow yang baik, kedua VGA diperkirakan mampu bekerja dengan panas 65 deg.C.

PowerColor X1950XTX & Sapphire X1950XTX memiliki heatsink dengan teknologi heatpipe. Satu pipa kecil dipasangkan dari pendingin heatsink ke inti VPU dan dihubungkan kebagian atas heatsink pada fin tembaga. Disain tersebut dapat memaksimalkan untuk meredam panas procesor VGA sehingga kinerja heatsink akan lebih efektif

 

Untuk cooling memory, X1950XTX memisahkan antara pendingin VPU dengan chip memory. Pendingin memory ditempatkan dibawah heatsink utama dengan bahan tembaga, dan ditempatkan di bagian depan dan belakang VGA

 

X1950XTX adalah VGA dengan kemampuan besar plus kebutuhan power diatas rata rata VGA standard. Minimal spesifikasi power supply untuk X1950XTX single, direkomendasikan memakai 450W power supply kelas premium atau lebih besar dengan 30 A pada 12V. Sedangkan untuk dual VGA atau Crossfire direkomendasikan dengan 550W atau 38 A pada 12V. Radeon X1950XTX mengunakan external power yang disuplai langsung dari power supply mengunakan konektor PCIe
