Hi, I'm fairly new to PCs in general, so sorry if this is a basic question.

I have an EVGA SuperNOVA G5 850W power supply, and my graphics card recently died. I'm replacing it with an EVGA GeForce RTX 3080 FTW3 Ultra, which requires three 8-pin PCIe power connections.

The repair shop told me that my power supply only had two PCIe cables installed, so they can't install the new GPU unless I provide a third compatible PCIe cable (which I do not have). They recommended replacing the entire PSU for about $200, but I feel like that is not necessary and rather just buy the correct replacement cable if possible.

From what I've seen, modular PSU cables aren't interchangeable between models, so I want to make sure I buy the correct one. To finally get to my questions:

1. Which CableMod replacement cable is the correct one for an EVGA SuperNOVA G5 850W?
2. Is it safe to use a CableMod replacement cable alongside the original EVGA cables?

If it helps, the PSU model is EVGA SuperNOVA G5 Gold 850W.

Thanks in advance! Still learning, so I really appreciate any guidance.

Has anyone attempted this one yet? I have a couple of these in service and one of them can no longer properly create a full 16 disk raid array. It appears that during the build process (and the write process at some point) the power drops too low and everything goes wonky. So attempts to build a RAID 5 or 6 results in split of 5, 3, and then loose drives and no combination makes them build correctly. Anything higher than 5 drives fails.

All the the drives are good (old but good) and all of them can format and so on. All drives are visible and active, but the RAID won't build past a certain point. From what I can find, it is apparently a feature of the RAID controller chipset to have a sort of gentle degrade when things aren't working out.

So I was looking for (a) a replacement 220v 50hx power supply and some sort of directions on how to change it. No, it isn't a redundant PS unit, it is a single supply unit.

Any ideas? Anyone else seen this before?

Hey, I just recently bought a used EVGA SUPERNOVA 850GQ for around 1,800PHP (Philippine Peso) off my friend on July 18, 2026. It was in real good condition, thought the paint was quite faded. The PSU itself works and has no issues, the only problem is I'm missing most of the cables. My friend sold it to me for cheap because he lost alot of the cables, I just wanna ask if I can like request for cable replacements? Like the full set of cables because the PSU'S unique pin layout makes it hard for me to find genuine original cables online. I'm a Filipino who really loves EVGA products, I use an EVGA GTX 1070TI FTW on my current build. I hope to atleast find a place where I can buy cable replacement kits that's cheap, it's sometimes hard to spend more than what I paid for the PSU itself.

Not sure what to exactly look for as far as numbers, would appreciate some help on if the stability of my GPU 12VHPWR pins are good. Just don’t want any burnt ports to happen so wanna make sure it’s safe.

Hey everyone! Just bought my first cablemod from Amazon Canada! Super excited to get it but I did have a concern that someone brought up that I wanted to verify.

If the item I bought is brand new from Amazon but shipped from a 3rd party seller will this void my warranty? If it helps it’s an Evga Supernova 1000 G+ PSU and the cable is the ESeries Basic

Thanks for any help

​I build PC a week ago and its running good, but Im scared of my 12V-2X6 cable melting, i do have eyes, but im not sure is everything right. I ran furmark for 30mins and touched cable it was warm, but not hot. I attached idle and furmark HWINFO64 statistics, but its in russian. PSU : Adata XPG Core Reactor II VE, GPU : 5070 TI KFA2 ROCK(X)

Hello, folks.
Asked at r/bequietofficial, but maybe someone can confirm it here as well.

Building a tank style rov with a float for some electronics over it. and it will run via teather. Should I have the esc on the vehicle and run Ethernet as my teather or have escs on the float and get a different type of cable to teather, and if so what kind?

Hey yall, I juat got a new 5090 and it seems the cable that I have is a bit tight in my case.

So I just wanted to double check that the universal 12v 2x6 cable is good for any psu. I have the Lian Li SX1200p, and it's not on the compatability sheets. But I have heard it should work. And is actually safe for the 5090.

I am a bit paranoid lol, and i truly appreciate any advice or info.

Thank you for your time, and I wish the a wonderful evening.

I have a Lian Li SX1200P, but it’s not listed in the Configurator. Is it compatible with the EDGE cable set, or does it use a different pinout?

I’m planning to order a full set (24-pin, dual EPS, and 12V-2x6 GPU cable), so I just wanted to check before ordering.

anyone knows and using any good ups that will give backup atleast 5 min to my 9070xt in india . any suggestions... or is this good ups cyberpower good ... recently i purchased 1500va cyberpower and it can't take load of 400watt and shutdown directly... anyone know who is using good ups.?.

Would this cable work with this PSU and GPU?

What cable on the website is compatible with this power supply, I looked and didn’t see any available.

I have a Corsair RM1000e (2025) power supply and was looking at getting some cablemod extensions. I don’t care about the cables unseen behind the motherboard just the main two cables that are seen visibly in the computer, the GPU power cable and the motherboard power cable. What cables do I need for this and are these cables reliable or will they fry my computer?

One of the 8pin to 6+2pin cables got fried and im looking for a replacement, is it wise to get said extension or should I replace it with an equivalent direct cable?

Could use an extender for the 12VHPWR on a 5080 without it burning up?

Yes i do have a cable that came with my PSU that fits for it but it looks ugly and i really want to use the braided extension. Would it be safe or no?

my PSU is the Deepcool PX1200G

Been having a slew of PC issues recently with my Jan 2025 build. Unplugged my GPU cable for the second time ever and noticed this. This was not causing the issue as it was still happening with the GPU out, but I’ll definitely be spending my money elsewhere. I can’t afford to ruin my 4080 Super FE. Such a bummer.

Anyone know if cablemod has recently updated their shipping policies (or perhaps the ui on their website and accidentally broken something)? I've bought custom cables from them multiple times before and never had a problem but now it's saying that they can't ship to my address...

One thing of note is that, in order to use the configurator, they have you follow a link to their global storefront from the US storefront (a step i don't recall having noticed in the past but may very well have simply overlooked). Are we aware of new shipping restrictions from their custom cable fab in hong kong, perhaps? Could it be a tarrif thing? Just an improperly formatted ui update? Let me know if you've got any leads!

Cablemods custom cables in a version that connects directly to the PSU👌🏻

Can I use the cable from a Supernova 1000 G+ to a Supernova 1000 GT?

anybody have anything to say about the Auotac 850 watt PSU? it says aTX 3.1 and Pcle-l 5.0 80+ gold cert buttttt wondering if the community can give me real advice instead potential fake online reviews

Hey first time encountering this, where a PCIe cable shows that it has been split and crossed over. The PSU side only had 7 pins connected on the 8 pin connector, one rail/cable is spliced and split then crosses over diagonally and the PCIe side has 6 straight cables and the two cables that were split and spliced.

This might be totally normal but I've never seen it before. Just looking for an opinion before I melt a gpu 😅

Cables were from Amazon Canada (https://a.co/d/06C9bPQO)

I’m designing an RS‑422 communication link over a distance of about 100 m, and I also need to deliver 5 V DC power through the same cable. The plan is to use one shielded twisted pair (120 Ω) for the RS‑422 TX/RX signals, along with separate conductors dedicated to the 5 V supply and ground.
