Upgrading Alienware Aurora PSU

Hi guys!! So I got the Aurora a few months ago (May more or less). Yeah, I know I could've paid like half the price if I had built it but I just don't have the time for it. Anyways, I got it with the radeon 5970. It didn't give me a choice as to which PSU to get, so considering I bought the 5970 (it's a dual gpu after all), I assume I got the 875 Watts PSU.

So recently I was able to save money for a second video card (another 5970) and I may need more power. My problem is this: I am not sure which PSU to get. Under techspecs in the alienware aurora website, it says under "Motherboard and Chassis Form Factor" that it has a "microATX motherboard, Mid-Tower Chassis."

Here's the website:

My question is whether an ATX12V PSU will be able to be installed on my system---because if I limit myself to microATX PSU, I am not able to find ANYTHING above 600 Watts for sale.

If indeed I am stuck with the 875 Watts PSU,

1) Will I still be able to get a 2nd 5970 working?

if not,

2) Am I able to successfully pair up my card with a 5870 instead?


3) Would pairing it up with a 5850 be more worth it than with the 5870?

Another note, I'm not doing any overclocking unless I get a 5870, in which case I would just overclock the 5970 to match the 5870 clocks.

Info on my system:

OS: Win 7 64bit Home Premium

RAM: 9GB 1333Mhz DDRe

CPU: Intel i7 960 @ 3.2Ghz (stock clocks)

GPU: single 5970 2GB GDDR5 @ stock settings

Optical Drive(s): 24x Dual Layer DVD-RW +/- Burner

Well, Thanks for the help guys!

  1. Its very rare for a case to use a microATX PSU, generally its very specialized cases. Your machine will take a standard ATX PSU, but you may need to modify that little airflow guide black plastic thingy to fit a large unit in there.
  2. Most likely there is an ATX power supply in your system. You would probably be pushing your luck with the current PSU and adding another 5970. 5870 might be ok. What resolution are you playing @ that makes you think you need a second 5970 or even a 5870 to pair with your current card? If you are playing @ 1920x1080, save your money or buy a higher resolution monitor.
  3. hi guys! thanks for the replies so far! and actually i have been playing at 1920 x 1080 but i ordered a monitor (getting shipped probably tomorrow) with a resolution of 2560x1600! :-D
  4. Yea I would wait and see how it does with the new monitor first. Maybe take a pic of the inside of your system and post it to see if you would have enough room in there for a larger PSU.
