The cableless 5090 — power delivered through the motherboard
Quick Specs
- NVIDIA GeForce RTX 5090 GPU with 21760 CUDA cores.
- 32GB GDDR7 memory at 28 Gbps on a 512-bit interface.
- OC mode boost clock of 2610 MHz.
- GC-HPWR gold finger power delivery — no visible power cable.
- 357.6 x 149.3 x 76 mm, 3.8-slot cooler.
What BTF actually changes
Back-To-Future removes the power cable entirely. Instead of a 16-pin connector on the top edge, the card draws power through a GC-HPWR gold-finger contact on the PCB itself, mating with a matching slot on a BTF motherboard. The result is a build with no cable crossing the window at all — the visual difference is substantial, and on a card this large it also removes the cable-bend clearance problem the 16-pin connector creates.
Requires a BTF motherboard
This is the important caveat: the card needs an ASUS BTF-compatible motherboard with the GC-HPWR slot. On a standard board it cannot be powered. Everything else is full ROG Astral — 21760 CUDA cores, 32GB of GDDR7 on a 512-bit bus, 2610 MHz OC boost, and the 3.8-slot quad-fan cooler.

Questions
Before you buy
What size power supply do I need for this card?
ASUS specifies a 1000W power supply as the minimum for a complete system built around it. That figure covers the whole PC, not the card on its own, so if your current supply is at or above it you are fine. If you are close to the line, or the supply is an older unbranded unit, it is worth upgrading at the same time - an underpowered PSU shows up as crashes under load rather than a machine that simply will not start.
Will this card fit inside my case?
It is 358mm long. Check the maximum graphics card clearance for your case and make sure it is more than that - allow a little extra for the power cables that plug into the top or end of the card. Every case we sell lists its maximum card length on the Specifications tab, so you can compare the two numbers directly.
Which GPU is in this card, and how much video memory does it have?
This is a GeForce RTX 5090 with 32GB of video memory. Video memory is the buffer the card uses for textures and frame data, so it matters most at higher resolutions and with high-detail texture settings. The full clock speeds, memory interface and display outputs are listed under Specifications above.
Is it in stock, and when will it ship?
This one is out of stock at the moment. Stock does come back in - WhatsApp us on 079 491 0181 with the model and we will tell you what the supplier is showing and let you know when it lands, rather than leaving you to keep checking the page.
What does delivery cost, and how long does it take?
We deliver by courier anywhere in South Africa, and delivery is R180 on orders under R2 500 and free on orders of R2 500 or more. It takes 1-3 working days to Johannesburg, Pretoria, Cape Town, Durban and areas within 100km of them, and 2-4 working days to areas more than 100km from a major centre, counted from the day the order is dispatched. Need it sooner? Express delivery is 1-2 working days for R210, or R150 on orders of R2 500 or more - choose it at checkout. We do not ship outside South Africa.
Can I collect instead of having it delivered?
Yes. Collection is from 11 Voortrekker Avenue, Edenvale, Gauteng, by arrangement - message us first so we can have the order picked and waiting. We are open 09:00 to 16:30, Monday to Friday.
What warranty does it carry, and how do I claim?
The warranty period for this product is listed at the end of the Specifications section above. Claims go through us, not the manufacturer - contact us with your order number and a description of the fault and we will handle it from there. Separately from any warranty, the Consumer Protection Act gives you six months from delivery to return goods that are defective, unsafe or not fit for their intended purpose.
What if I change my mind?
You have 14 days from delivery to change your mind - longer than the seven days the Electronic Communications and Transactions Act requires. The item needs to be unused and in its original packaging, and we pay the return shipping. Refunds go back to the payment method you used, within 30 days of the return reaching us.
How can I pay?
Payments are processed by Stitch. At the last step of checkout you are taken to Stitch’s secure page to pay, and brought back here once it is done. Your card details are entered on Stitch’s secure, PCI-compliant page and never touch our systems.
