AMD Radeon HD 6870 GPU in a Dell XPS 8300?

I've ordered a Dell XPS 8300. It has a 460W power supply. The video card options ranged from the ATI Radeon HD 6450 up the HD 6870. I chose the 6450 - it was included in the price - but I have a ASUS Radeon HD 6870 (retail box).

AMD, however, lists the power requirements of the 6870 as 500w. Rechecking Dell.com, I see that the card they offer is described as "Single ATI Radeon HD 6870". An OEM variant, with lower power consumption, I guess.

I've heard that AMD gives the 500W figure to discourage people with cheap power supplies from pushing their luck.

So, what do people think? The Dell power supply should be able to cope, right? (He said hopefully.)

I'll be installing a Intel SSD and a WD 2TB Caviar Black HDD. I do have four+ external drives, but they're not connected all of the time.

Thanks for the advice.

a quality 460 PSU will power 6870 but usually the PSU that is usually used in this kinds of builds is crappy :)

Best not to make assumptions, the oem GTX560 has a higher rated TDP than the retail version, you never know.
That's the basic premise from both AMD and Nvidia

Thanks. Hmm, I thought the power supply in the XPS 8300 was good.

@delluser1. I'm confused! The XPS 8300 has a 460W power supply. So how can the ATI Radeon HD 6870 be an option when you configure the 8300 on Dell.com?

Because Dell knows it's the 12v amperage, not the labeled wattage, that counts.

Hmm, interesting. So do you think I'd be okay with the ASUS Radeon HD 6870 retail box?

I had the same issue last year - I wanted to put an HD 5670 in my Dell, but their PSU was rated 300w, and AMD recommended a 400w. Asked around and was reassured it would work fine even with a 95w CPU as well. Popped it in, and I've been hooked on PC gaming since. It will definitely work, especially since Dell is advertising an HD 6870 upgrade with it - means they are fully confident it can handle that card with ease. Just don't go crazy with voltage tweaking.
