Alienware X51 GPU upgrade

Hey guys ,

I got a x51 recently, which comes with the ATI R9 370 ( the 4gig OEM model), but am looking to replace it with a better card. Really the one I want to switch it with is a GTX 970, but it's a much more powerful GPU and I am still a bit worried about doing it since the power supply is 330 W. (and also the length of the card has to be max 9.5" , but I think some 970 models allow that.)
As far as I've read on forums some people have done it successfully.

So my question is have any of you guys had experience with this, or if you can verify if it's possible? Will provide full specs if needed.

I'd want more power.

The 330W is from my experience far better than run of the mill 400 Watt PSUs. When we replace a PSU I replace it with one that I tap 50% of max and keep it a single rail model.

330W is definitely less than you see called for on this GPU and no one should tell you it's OK. That doesn't mean it won't work.

Modded double PSUs

Well the current R9 370 has a 150 W max power consumption. I'm not sure how much the 970 consumes, but I can't imagine it's much more. Also, I can underclock it if needed.

But I am really interested in this ----> http://forum.techinferno.com/alienware-m18x-aw-18/4250-...

Guy says he modded a laptop to have double PSUs. Then goes on to talk it could easily be done on a X51 too. I've also read other posts about this too. It would essentially allow me to put a Titan on it, if that's what I was after.Any thoughts on that?

Lost me there.

Laptop? Thought this was a desktop.

Anyhow, anyone the exceeds 50% of PSU ratings is not playing it safe. Your choice at the end of the day.

Mod?

Well he modded a laptop, but the PSU is practically the same for the x51 which is a small form desktop. I didn't quite understand your thoughts on the mod? Are you saying it's risky or are you talking about just putting the 970 on the current power supply?

Here's my rule for power supplies.

Design with 100% spare power. That means if I pull 150 Watts then I fit a 300 Watt PSU.

Let's say you want to push the limits, or are stuck in a small form factor machine. You have to make those choices. If you want to go off the reservation with some non-standard mod, then you make that choice.

Why? Because no tech I know will tell you its OK.

The x51 has some hundred configurations out there. I can't guess what you have but even if I did I would put it on a Watt meter like a P2 Watt Meter (see amazon) and see how it's doing.

I'll hold off on the mod for now

I guess I'll hold off on the mod for now, as the rig still runs games pretty well. Maybe in a year I'll just convert it into a bigger tower and buy an internal PSU. The I can have all the upgrades I want. PC master race amirite?

Thanks for the advice man! Happy
