Hi, 

I know that replacing the power supply in the Core X is possible because I read several articles of people wanting to reduce the noise of the case. But I come here to know if I can change the power supply by a more powerful because I currently have a Dell XPS 9560 and a gtx 1070-ti, with the 600W PSU provided by razer I do not have enough power to properly charge my computer ... Can I replace it with a 700W or +

Thank you in advance for your answers 🙂

I was trying my Gigabyte G750H but this PS is longer than Core X PS, so Core X fan need to be removed to fit G750H.
I haven't replaced it though.

TL;DR -Difficult to find ATX PSU that will exceed power rating of OEM PSU in Core X AND not require removal of other installed hardware

Jumping in late to the response, however I noticed that most of the commercially available PSUs, especially those that would offer higher wattages or gold/titanium ratings tend to be too big to install as a drop-in replacement for the Core X. Unless you are willing to remove the bracket that holds the 120mm case fan, you will need to find a PSU that has the following dimensions +/- 1mm (I used a metric tape measure)

88mm x 151mm x 142mm

If you exceed the 88mm depth by too much, you will bump into the PCB board inside the Core X
If you exceed the 142mm depth, you will have to remove the fan bracket <--This is your most likely limiting factor**
If you exceed the 151mm depth, you are ok as there is still room between the top of the PSU and the Core X's outer enclosure

From commonly available models at Microcenter, it seems the 88mm will be the sticking point. I only saw 500 watt range PSUs that met this spec. So unless you are downgrading for noise, it's not worth it IMO.

Finally, consider that the top intake fans of most PSUs would be taking in the warm air coming off of your GPU before exhausting it out the rear of the Core X. Not sure if this few degrees would affect PSU performance.

Hello. I bought a Seasonic Prime Ultra Titanium 1000W before realizing that it's not a drop in replacement. Size wise, I know it will exceed 142mm depth so I will remove the fan bracket. I still have two questions but my Core X hasn't arrived yet so could you please help me with them?
1. After removing the bracket, is there anything else on the bottom like screw holes that block the PSU?
2. From the picture, Core X PSU's port and switch placement only matches Corsair SF series and some Silverstone ones. Is it possible to modify that like remove the stock panel? Or if I remove the fan bracket, can I just mount the PSU with Velcro and connect the power cable through the stock opening? The disadvantage is that I can't access the power switch anymore but I think I'll just pull the plug. Thanks in advance.

As far as I can see, there are two metal posts (one for each screw) that support the bracket. They seem to be pressed into the metal base. Removing them will, probably, void the warranty. Also the screws, that are holding plastic rails, are not flushed, i.e. raised to height approx. 1 mm above the surface.

Unfortunately, it doesn't seem that the back panel is removable. You could cut additional holes with a dremel, if you don't care about the warranty, or move the PSU deeper inside the enclosure.

This topic caught my eye as I was also contemplating acquiring a Core X and upgrading the Stock PSU with a Corsair
SF Series SF750 — 750 Watt 80 PLUS Platinum Certified High-Performance SFX PSU.
It measures 100mm x 125mm x 63mm.
It is on the pricey side @ $180.00 USD on Amazon. I'm assuming it would work even though it isn't an ATX PSU.
Perhaps this may be something you might be interested in.

The other one I found is SX800-LTI. Both one in theory should be plug and play. SilverStone one has titanium rating and slightly higher power. SilverStone's ATX can fit the panel but you need to remove the fan.

I guess I will stick with my prime ultra titanium. Vega 64's instantaneous power usage is quite high so 1000w leaves enough safety margin. I'll post a build guide when I finish my build. Really wish Razer can just remove the fan design and leave the back panel empty like PC case.

Good to find this article. So it's not only me who were complaining about stock PSU's noise.
I want silence at least when my laptop is off work, just charging.
I found seasonic focus plus 650w gold model does not over the size  of 88mm x  151mm x 142mm since it's 86mm x 150mm x 140mm
it also got zero-fan function up to 30% of usage, which can cover 100W of power delivery to my macbook.

So is it just simple task for this model? taking the original PSU off and replace it to the new one?

If you check the back panel layout, seasonic ones won't fit. After searching, I only found two drop in replacements that are better (efficiency, noise, wattage) ones than the original one. Corsair SF750 (Platinum) and Silverstone SX800-LTI (Titanium). Both are good ones but neither of them use fluid dynamic bearing fan which is a shame for such pricey PSUs. So I picked up Seasonic Prime Ultra Titanium 1000W. Will write a build guide when I have time to build the thing.

Thank you for further information!
But those you recommended feel so pricey for me, trying to find more affordable ones. All I want is silence during charging. But I still can’t get the back panel thing. How can I know which one is compatible and which one isn’t? It looks all same to me.

Anyways, I’ll look forward to your build guide.
