Benchmark Scores I dont have time for that.
I have a razer x chroma the one with the extra little add on board for usb and Ethernet. In my other log I have been tracking performance and having fun with my latte panda; however now that I have a 9700XT and my 4090; I started to grow concerned with power. The default PSU is only 700w and limited in connectivity. If I wanted to graduate to today’s GPUs like the 4090 or 3x 8pin 9700XT it was time for an upgrade.

Now the razer x doesn’t have a normal SFX PSU. Iv owned both and while the stock one is more or less the same the real issue with space comes from the chroma which has an L shaped PCB for the addin card which sits next to it.

Additionally the psu has a bracket that attaches too it and an elongated switch and receptacle. Neither are flush with the PSU; instead they stick out about an inch or two from it.

This means any replacement would need to line up with the hole in the chassis, clear the PCB and well fit.

Thankfully someone on the met mentioned that the corsair SF1000 might be able to do it. Not left with any real choice if I wanted to continue using this enclosure I pulled the trigger. Let’s dive in together.

As we can see in stock configuration the PSU has two shared brackets. One with the rear of the chassis and the other with the fan assembly. These will be useless given the custom size so we will need to tear it all down and figure it out.

After removal a test for was needed. Near the rear of the chassis is the short side of the “L” on the PCB. We need to make sure we can clear this.

Next was the actual power switch and receptacle. Thankfully this does line up even though the mount holes don’t. The “extension” on the OG psu is not removable. Additionally trying to use the custom bracket would just leave us with a gap. This might be ok if you want to snake the power cable into the hole but it is a sharp edge and it would be a bit of work.

Instead I figured some double sided tape would do; but true strong double sided tape is a bit thick. However command strips while thin actually seemed to work quite well, the reason being they are just as wide like gum and that’s what you really want; surface area. The addition of the tongues for easy removal is just a bonus.

Thankfully both the PSU and chassis were smooth enough to accommodate as porous or blemished surfaces tend to do badly with double sided tape.

Time to connect all the cables making sure they fit and to future proof. The mobo connector is standard and the “CPU” 8 pin is used for slot power at the back edge.

12vHPWR coiled up nice in the new space. The PSU is quite a bit shorter which helps with all the extra cables.

All installed but we need to work on air flow now.

Much better; the 7900XTX is going back in for now but I may switch to the 9070XT in a few weeks so I prepared 3x 8PINs in advance.

With the cables tucked and wire tied it was time to reinstall the fan and check clearance.

Good news the PSU fan faces the right side exhaust which on this enclosure is pretty much all mesh. About 1/3 of the fan sees the mesh but there is a nice 1/2 to 1” gap between the PSU and the inside of the chassis so I’m not worried about airflow.

It all fit and with a quick connection of the 7900XTX I attached it to my test SBC and it fired right up.

Alls well that ends well, now to figure out where I’m going to cut to route the hoses for the 4090s AIO I’m thinking an “L” cut into the top as I’d like to maintain the chassis.

Maybe some 4” mobo riser screws so I can mount the rad into the top after tapping some holes.

Another time maybe.
