Aurora R7, RTX 3070 upgrade help (complete noob)

Hi there,

I am a complete noob when it comes to actual pc building and upgrading. I currently own an alienware Aurora r7 (460w, gtx 1080, i7 8700, 32gb ram) and having seen the new rtx 3070, I am starting to think through upgrading to it at some point in the next 12 months. I have gathered that I will probably need to upgrade my psu, so:

1) what wattage would be recommended?

2) will any psu fit/work with my pc?

3) will an rtx 3070 fit in the pc?

4) finally would the 3070 cause my pc to overheat I have seen lots of conflicting information and dont really understand any of it.

I really appreciate the help and any other advice you can give.

Thanks!

1: on the NVIDIA website, the recommended wattage is about 650 watts. I would advise maybe doing 800+ watts but you can upgrade what you like. You may not need the upgrade to the 3070 anyway, since 460 watts is not enough to run the 1080 at optimal levels. I am confused on how you are able to even run your system with that amount of power. You are correct about upgrading your PSU though.

2: There is a video showing exactly how to upgrade your PSU on the Aurora R7 case: https://www.youtube.com/watch?v=fzUxA0Camn0

Watch that and see if it gives you any information about what size or type of PSU you should buy to fit the case. If not, you can search this very easily and find which PSU's will work the best.

3: The RTX 3070 will fit nicely in the R7 case. It is listed on the NVIDIA website as 9.5" in length which is more than enough breathing room for the insides of your pc.

Lastly, there is no reason to believe your PC will overheat if you have the proper cooling and all case fans are operational (which Alienware takes care of for you). There is also a reason these GPU's come with fans, as they will be used to cool themselves down, so you shouldn't worry about the GPU overheating unless there is a manufacturing issue. If you have doubts, open your case up and check to see if the case fans are working correctly.

i was happy to help, and ask me anything else if you want. I also own an R7, and i 100% recommend upgrading your PSU before anything!

@Enigma Clips   It is listed on the NVIDIA website as 9.5" in length which is more than enough breathing room for the insides of your pc.

There is more than enough breathing room, unless the top-side exhaust fan is breathing hot air right into the bottom of the PSU swing-out contraption, which has yet to be confirmed. If you do not already have a liquid cooled CPU, that would also be a necessary upgrade, as you can see from this air flow schematic, an air cooled CPU would be in BIG trouble.

Hi there,

Thank you for getting back to me, I can see how that cooling might be a problem, if I were to wait and get a third party 3070 with a different cooling set up such as a blower, would this remove the need for liquid cooling? As that really isn't something I would feel comfortable with. Thanks again for your help

Hi there,

Thanks so much for your response, I had no idea the stock psu was not enough for my specs, it was the one alienware provided, I will look into upgrading that first then!

@E11iot13    if I were to wait and get a third party 3070 with a different cooling set up such as a blower, would this remove the need for liquid cooling?

The RTX 3070 runs 220 watts, so if you were to install a blower style graphics card, you might get away with an air cooled CPU.  I don't understand why you would not feel comfortable with CPU AIO liquid cooling

Dell sold the R7 with either a 460w or 850w psu depending on your configuration the 850w was either mandatory or optional.

@Anonymous I agree 100% that the upgrade to liquid cooling would be the way to go.

I am also considering upgrading my GPU to the 3070, but i dont have the R7 i have a dell g5 5090 smaller case, with a 460w PSU so im guessing im going to have to update my power supply also? any models suggested that will fit in my case?

@Arch_VDN     i have a dell g5 5090

I'm pretty sure the G5 came with either a 360 watt PSU or a 500 watt PSU. Those are Dell proprietary power supplies . . . there is no 3rd party replacements. For the RTX 3070 nVidia requires a minimum 650 watt PSU. I don't believe that is possible in the G5.

What if i wanted to change the PSU, i was thinking of a Corsair RM750x. but im not sure if there is a risk of burning my motherboard? i currently have the 460W PSU but i feel its underpowered for the 2060 super i have @Anonymous

You are correct . . . it is under-powered. However, the Corsair RM750X comes with a standard ATX 24-pin power connector.  Your motherboard has a Dell proprietary 6-pin power connector. There is no 3rd party PSU that will work with the Dell G5 motherboard . . . unless you were able to do your own custom cable pin-out.
