I'm not sure whether I should use my current power supply with my new build or buy a new one. My current PSU is a 750w Dell one that was stock for my XPS 630i. I believe the model is 'DT50E', but I don't even know if there is any info out there about it. I plan on using my current GPU, a GTX 460, so I know 750w is enough. However, since my current power supply is ~3 years old and a somewhat mysterious Dell model, would it be better to buy a new one? I haven't decided on a motherboard, and I'll probably get an i5-2500K. This could be an easy decision, but I don't really know much about PSUs.
OEM PSU's won't exactly be crap. They do work for the rig they come with. On that note, I guess a 750W PSU from dell will surely be good to handle a GTX 460 rig. Moreover, its one from the XPS range. So should be pretty much standard.
