Will the 460 PSU in a Dell 8300 run AMD 7850?

Will the 460 PSU in a Dell 8300 run AMD 7850?

The rest of the system is a i7 2600, 8 GB, and Blu Ray and 1 TB hard drive.
 
I have also been looking to upgrade a video card in a 8300 as I am not thrilled with the 5770 that it came with

FWIW Dell states the highest cards that they validated with it are the AMD Radeon HD6950 and the Nvidia GTX560( Non Ti)

The 7850 uses much less power than a 6950 so should also work
 
Then it may not be enuf as Dell PSUs will usually be crap and when a company recommends 450 watts it means at least mid quality 450 watts,

it may be okayish but not ideal
 
A Dell PSU 450 watts may actually just be a 200-250 watts actual weight PSU, so it all depends on that. They don't use Corsair or Seasonic unit I guess

From what I hear, Dell PSUs used to be crap like that but they've improved in more recent years. It may not be a Seasonic, but it's probably capable enough to deliver its full wattage though not in continuous use
 
Dell PSUs are not the best PSUs, but they do what they're rated for. If it's rated a 460W power supply, it's a 460W power supply. There is no way Dell would put a 250W PSU into one of their own computers and call it a 460W. That would be just plain stupid; what if someone actually tried to use 460W and burned their computer because it was actually a crappy 250W PSU? Dell has to pay to replace the entire computer. It makes no sense for Dell to cut corners that much.

Dell PSUs aren't great, but they aren't time bombs that'll kill your computer. They do what they're supposed to do, within spec, and they do it for years on end.
 
it could run it with no probs, however you will have OCing probs later on and "heat" might be a problem too.... i'd recommend you upgrade to a 650..
 
650W...? Seriously? On a Dell XPS which you can't overclock to begin with?

A 7850 in the Dell XPS machine as stated in the OP will never have any problems due to not having enough power. Yes, you can quote me on that. Check out reviews for the HD 7850. Even Anandtech's overclocked SB-E setup, with an overclocked HD 7850 (22% OC), has a power consumption of 311W. At the wall on a Quattro 1200W PSU, so closer to 280W from the PSU itself. The OP's Dell uses a much less power intensive platform (regular SB) and it can't be overclocked.
 
It will work without any issues. I have a 3 year old corsair cx400 with i5 2500k o/c to 4.5ghz 1.328v, 16gb ram, ssd + 1tb hd and a radeon 7850 o/c 1050/5800 no issues.

do you have any actual evidence of this? i've never run into an instance myself of dell underrating PSUs, not have i had one burn out on me.

usually when nvidia and amd have to recommend ginormous supplies it's because of trash like this:

People were using 8800gt's in dells with a 300-305 Watt psu no problem. If it was my PC I would do it and not worry about it at all that PC isn't going to eat a lot of juice...
