Question for anyone using the 400R/500R line from Corsair. Are you using a non-modular PSU, and if so, what are you doing with all the additional cables?

I've used the grommets to feed the extra cables out of the way but I can't get the side panel (wire management side) to close. The extra cables from the PSU creates too much bulk to be able to close the door with ease, and I'd rather not force it.

I'm using the XFX 650Pro and it has the Motherboard Cables, 2x Molex with 4 connectors on each, 2xSATA power with 4 connectors on each, and 4 PCI-E Connectors (total of 10). Realistically I only need 4 of the 8 cables.

I've got a 500R and a non-modular PSU and it's a nightmare.

I've tried to pushmy cables along the curves in the back of the motherboard tray but to little avail. The side panel slightly bulges on the edges. When I had to remove my H100 for RMA with my retailer I decided that I would tidy it up... and I failed.

My Seasonic S12-II 750W seems to have about the same number of cables as your does. I'm wondering if I should re-cable it to get all of my cables behind that rather nice buldge in the side panel. Couple of markers to note where i need to plan and it could work.

I'm grateful for the level of Seasonic service they have provided and the excellent PSU's (despite having fan issues, twice!) but too many cables! and I now wish I had a modular PSU.

Same for me. I'm considering just pushing the unused cables through one of the grommets and sticking them under the optical drive, but I'm trying my best not to obstruct air flow. I might just end up returning my XFX 650Pro and getting myself something Modular to save the hassle.

Isn't there plenty of room right next to the PSU?

There's practically nothing there in a volume the size of a the PSU. Just leave the excess cables there if you cant put the behind the mobo.

Would that cause any airflow issues? There isn't much right next to the PSU, but there dual intake fans right there, meaning the air would hit the wires and obstruct the airflow. Also, I'm big on a clean managed case, and it would really bother me to have a lump of cables there.

I have a 500R with a Pc power and cooling 750. I dont know what you guys are talking about but there is ample room on the backside of the case for all my wires.

This case is a dream for cable management

Are you trying bunch them all together? That's not gonna happen. Just space them out back there and all will be well. I can't imagine you have more cables than me and I have plenty of room

As long as you roll and tie the extra cables up into a neat pile, they shouldn't impact airflow at all really. Most of the air from the front fans will be drawn upwards to the GPU and CPU intakes anyway, so I can't imagine it'd be a problem.

To me it looks there's plenty of space:

[edit: not my setup, from a review]

Maybe share a picture of your setup?

This case is a dream for cable management

I got a 500R to replace my three hundred. My god, it was a nightmare to move stuff over.

- 2 of my SATA cables, the connector was incompatible with the case because the hard plastic part was too long. The drives sit way back so there is room in front of the drives, but that made the connectors interfere with the door when I tried to close up the case. I never even thought this might be an issue, so I ended up breaking one of my drive's SATA connectors because of it. If the bulges were in a different place (near the HD rack) that might not be an issue, but they aren't, the drive is skinniest right where the HD connectors are. I had to root around in my stash to find "short" SATA connectors.

Perhaps that is a problem with all cross mounted HD cases, I don't know, but it was a surprise to me to find that I had cables that were incompatible with my case.

- As a result of the SATA connector breaking off in the cable, I had to temporarily use an old IDE drive. The power connector wouldn't fit through the space in the cage unless I pried the drive over with a screwdriver while I plugged it in... compressing the rubber on one side and eliminating any vibration damping. Also the power connector is constantly side loaded now. At least until I can replace that drive with a SATA drive.

- The case as a whole does not feel as sturdy or is as low resonance like my cheaper three hundred with it's rigid drive bays. The removable / modular 3.5" drive bays may be great for airflow, but there is a definite trade off in rigidity and resonance of the case vs. the three hundred's design with a solid piece top to bottom.

- The cable management was good in that there were grommets and such, but not much room behind the door meant some very careful planning of cable routes and even then some muscle was needed to get that door on and closde. I do have a modular PSU, so I don't have quite the same issues that the OPs are talking about. I have just 5 cables to the PSU (24 pin, Aux 12v 8-pin mobo, 6 pin GPU, SATA, fan).

I can see how the OP would have some issues. At the end of the (long) night, I ended up with a cleaner looking install than my 300, but it came only after a fair bit of time figuring out the best way to route things, some frustration and even some muscle in getting that cover in place.

The 300 routing is quite easy and intuitive, with re-closeable fasteners and the conventional 3.5" drive bay leaves a LOT more room on the side for cables. I always had plenty of room, even though that case is not as wide as the 500R.

- The really awkward thing is that Corsair includes a really nice, easily removable fan intake filter... on the bottom of the case where very few people mount fans. But the front of the case? Where fans come pre installed? That one's much more difficult to deal with, and is significantly more difficult than the one on the 300.

Perhaps my expectations were too high, but I was not as impressed as most of the reviewers of the case. Comparing it to a significantly cheaper case, I found many faults. It seems a lot of attention to detail in the aesthetics with everything painted. I think they ended up trading more functionality than I expected for these aesthetics. Conventional 3.5" HD mounting or 0.5-1" extra width would go a long way on this case, IMO.

If you don't push the hard drive all the way in until the side of the case is on you wouldn't have had that problem. I have right angle sata cables too so it was a non issue, nor was it for my ssd.

I have broken a sata connector before on a hard disk. It was still usable though. Basically if you leave the broken piece inside the cable and very carefully straighten the pins it will slip back into place, then follow up with a hot glue it will be as good as new. Obviously the cable will be semi permanent after that.

I don't think you understand the issue I had. Solid objects cannot be in the same place at the same time. If I closed the case and tried to put the drives in, they would not have been able to click into place. They would have just been loose in there and tipping the case would have slid the drives out, hanging by their cables (and potentially dropping to the floor, ouch.) This is because the length of the hard plastic part of the sata connector I had been using was longer than the case was designed to handle.

As I said, it may be something that's common with sideways drive mounting, it was just new to me. I was also able to find plenty of cables in my stash that had shorter connectors. Must have been one or two motherboards a while ago that came with funky cables.

If you separate the cables and route them along the back of the motherboard wall you get much better management. I was forced to put the two remaining unused cables into the hard drive cage for now - otherwise I couldn't close the back panel. I'll post a picture when I finish - the space behind the motherboard looks terrible but as long as it closes, I'll deal. I'm probably going end up using the two currently unused (even though I don't need them) for better management.

On my next build I'm getting a modular PSU for sure.

Hmm, disheartening. Seeing lehtv setup and having been swayed from the CM HAF-X to this case I am starting to wonder if that was a good choice.

Once you figure out how to get things so the panel will close, the "visible" side looks great, no doubt. The issue is getting to that point.

The motherboard is kind of recessed, as you can see in the picture. There is some space where the grommets are and where the case side bulges out, but near the hard drive cage and routing any cables that don't fit in that channel around the motherboard, things are dicey.

It can look cleaner than other cases I've dealt with, but the amount of work to get it to look that clean is more than I was expecting.

Agreed. My case is set up nicely now - I'll post a picture soon. Haven't booted the thing up yet because Corsair didn't send me any fan screws so I can't mount the top or side fans.

Why can't you use it without extra fans?

I could, but I'd like my top exhaust at least get set up. I'm also still backing up my old PC so I need to wait a little.

I just spaced all the cables on the backside and secured the to the back plate.
All is well. NOTE: I did use 90 degree SATA cables. It's tight but it works.

I didn't have much of a problem keeping my wires tidy on my 400R setup. Just have to spread the extra wires out along the back where the hump is on the side door. I had plenty of connectors left over on my XFX 750W, I think it looks nice now...
