That's assuming that everything is working correctly though. It's certainly not unheard of for people to die from working on faulty PSUs.Not when it's powered down and the capacitors are discharged, I've worked on PC PSUs before without an issue. It's not like a CRT TV which has actual high voltage components.
Note that for this series, it would be using a Vista driver. Vista drivers many times work with Windows 7.The oldest NVIDIA cards that can support Windows 7 with a legacy driver are the FX 5000 series.
