Description
To those who say this Silverstone 1500W power supply can't handle the load, I say "feh!"
In this video Linus Tech Tips demonstrates the power and heat performance of a 4‑way SLI rig built around four GTX 480 cards, a Silverstone 1500W power supply, and an Intel i7‑980X CPU. He begins by checking idle GPU temperatures, which sit around 60°C, and then runs 3D Mark Vantage to gauge power draw, noting a wall consumption of roughly 700 W during the benchmark. Linus explains how a 1500 W PSU can comfortably supply the system, delivering about 1150–1200 W from the wall and leaving a margin for future overclocking. He also highlights the peak GPU temperature, which climbs to 85 °C on the top card, and discusses potential cooling improvements. The video concludes with a brief look at future 3D Vision surround support and a call for viewers to share their own power‑consumption data.
Viewers largely praise Linus for clarifying the power‑supply needs of a 4‑way SLI build, with several comments noting the 700 W wall draw and the 85 °C peak temperature. Many users express enthusiasm for the 1500 W PSU’s capacity, and a few mention future overclocking plans. The comment thread shows a mix of technical appreciation and casual humor, with a high‑like comment at 2:03 and a supportive remark at 81 likes. Overall, the community feels the video is informative and well‑executed.
