AI Verdict
These 16AWG extensions give your PC a custom look for under $30, but you need a case with deep routing space to hide the massive wire bundle.
These cables look fantastic and the 16AWG wire safely handles high-wattage GPUs, but the sheer volume of extra cable makes them a nightmare for compact cases. You are adding a foot of thick wire to every major connection. If your case lacks a deep basement or wide rear channel, you will not get the back panel on.
If you have a small form factor case, buy custom-length direct replacement cables from CableMod instead of using extensions.

Pros
- Upgraded 16AWG copper wire handles up to 1000W loads safely for power-hungry GPUs like the RTX 3080 or 4070
- PET braided mesh exterior bends easily around tight corners without sagging or shrinking
- Includes four cable combs per 30cm cable to keep the individual wires perfectly parallel
- Silver-plated connectors provide a tighter, more secure fit than standard tin-plated alternatives
Cons
- Adding 30cm of thick 16AWG wire to your existing PSU cables creates a massive bundle that is incredibly hard to stuff behind the motherboard tray
- The 4+4 pin EPS CPU connector is notoriously stiff and requires excessive force to click fully into the motherboard
- These are extensions, not direct replacement cables, so they do not plug directly into a modular power supply
Dimension Scores
16AWG pure copper handles 1000W loads easily without heating up.
Passive component with zero electrical whine.
PET braiding is soft and premium, but the plastic connector housings are slightly stiff.
The combs work great for the visible front, but hiding 30cm of extra 16AWG wire in the back of the case is brutal.
Best For
- Mid-tower or full-tower ATX builds with at least an inch of cable management clearance behind the right side panel
- Showpiece gaming rigs with tempered glass side panels where aesthetics matter
- High-draw systems pulling up to 1000W that need thicker 16AWG wire to prevent melting
Not Recommended For
- Mini-ITX or small form factor builds where hiding an extra 30cm of cable is physically impossible
- Plugging directly into a modular power supply unit
Watch Out For
- Back panel bulge — you are adding 30cm of thick 16AWG cable to your existing PSU cables, meaning you will likely need zip ties and brute force to get your case's back panel closed.
- Stiff CPU connector — multiple users report the 4+4 pin EPS cable requires massive pressure to seat fully, which feels terrifying when pushing against a motherboard.
- Reboot crashes — if you don't push the PCIe connectors in until they audibly click, the voltage drop under heavy gaming loads will trigger sudden PC shutdowns.

What Buyers Say
The visual upgrade these cables provide is undeniable, transforming a messy stock build into a custom-looking rig for under $30. The 16AWG wire thickness gives serious peace of mind for high-wattage GPUs, completely eliminating the melting risks associated with cheaper 18AWG kits. The front of the case will look immaculate thanks to the included combs and soft PET braiding. The back of the case will become an absolute warzone. Hiding an extra foot of thick cable requires aggressive zip-tying, and many buyers had to literally sit on their case's back panel to slide it shut.
“Looks amazing in the front but my god the back of my case is a disaster area now, I literally had to use my knee to force the back panel closed because these cables are so thick.”
Common Praise
- 16AWG wire stays completely cool to the touch even when pushing 350W through an RTX 3080
- PET sleeving is incredibly soft and holds a curved shape perfectly without kinking
- Included cable combs snap on easily and keep the individual wires perfectly parallel
- Pure white color matches white motherboards and cases perfectly without looking yellow or cheap
Common Complaints
- The extra 30cm length creates a massive rat's nest of cables behind the motherboard tray
- The 4+4 pin CPU connector is extremely tight and feels like it might snap the motherboard when pushing it in
- Takes up so much space in the PSU shroud that you might have to remove your hard drive cage
- The plastic connector clips are brittle and can snap if you try to remove them after installation
Ownership Tips
- The PET braiding collects dust over time and requires a quick wipe with a microfiber cloth to keep the white looking bright
- The stiff plastic connectors loosen up slightly if you unplug and replug them a few times before final installation
- You will likely need to buy extra zip ties, as the few included in the box aren't enough to tame the massive cable bundle in the back
Frequently Asked Questions
Do these plug directly into my modular power supply?
No. These are extensions. You plug your existing PSU cables into the female end of these, and the male end into your motherboard and GPU.
Will 16AWG wire work if my original PSU cables are 18AWG?
Yes. 16AWG is thicker and handles more current than 18AWG. Moving from a thinner wire to a thicker extension is perfectly safe and won't cause resistance issues.
Are these safe for an RTX 4070 or 3080?
Yes, the 16AWG pure copper core is rated for up to 1000W. Just ensure you use two separate PCIe cables from your PSU, not a daisy-chained pigtail.
Do they come with cable combs?
Yes. The kit includes both black and transparent combs, giving you four combs per cable to keep the routing perfectly straight.
Why does my PC shut off when playing games after installing these?
You likely didn't push the connectors in all the way. The plastic housings on these are very stiff, and a loose connection causes voltage drops under heavy GPU load.
Buying Guide
You are buying these purely for aesthetics. They do not improve performance, but they hide the ugly ketchup-and-mustard or flat black cables that came with your power supply. Because these are extensions, you are adding 30 centimeters of thick wire to your existing cables. You must measure the space behind your motherboard tray or inside your PSU shroud before buying. If you have a compact case, you will not have room to hide the excess wire.
16AWG Wire Gauge
AWG measures wire thickness — the lower the number, the thicker the wire. 16AWG is thicker than standard 18AWG, meaning it acts like a wider highway for electricity, preventing the cables from melting under heavy loads.
PET Braided Sleeving
This is the plastic mesh wrapping around each individual wire. It makes the cables look like premium climbing rope instead of cheap rubber, and helps them hold a clean curve.
30cm Length
This is exactly one foot of extra cable. It gives you enough length to show off the colored braiding in the front of the case, while hiding the connection to your ugly stock cables in the back.
Alternatives
If you have a small form factor case with zero cable management space, search for custom replacement PSU cables specific to your exact power supply model to avoid the extra bulk of extensions.
