The 1200W Strix is the 1000W unit with 200W more ceiling for roughly 30 grams more weight, which is the cheapest headroom in the ROG range.
Quick Specs
- 1200W continuous output, 80 Plus Platinum certified
- ATX 3.1 with a PCIe Gen 5.1 16-pin (12V-2x6) cable terminated at both ends
- Fully modular, four 6+2-pin PCIe leads plus the 16-pin
- 0dB fan button, Cybenetics noise level certification A
- 160 x 150 x 86 mm, 1.84 kg, 10-year warranty
Buy the ceiling, not the average
A 1200W platform is not about running 1200W. It is about sitting at 500 to 700W typical draw, well below the point where the fan ramps and well inside the Platinum efficiency curve. That matters if you are running an RTX 5090 next to a 16-core CPU, or if you have a workstation that spends hours rendering rather than minutes gaming. For a single mid-range card this is dead weight and the 1000W Strix is the better buy.
What you plug into it
One native 16-pin cable at 750mm handles a 50-series card with no adapter. Beyond that there are four separate 1-to-1 PCIe leads at 750mm, which is the right way to feed a card with three or four 8-pin sockets since each connector gets its own run back to the PSU rather than sharing a daisy chain. Two SATA cables and a peripheral lead cover storage and accessories. Depth is 160mm, so measure the basement in a compact case before ordering.
FEATURES:
- 0dB fan button keeps the fan stationary until the system reaches a set load
- Cybenetics noise level certification A
- ATX 3.1 compliant with a native PCIe Gen 5.1 16-pin cable
- Individual 1-to-1 PCIe cable runs rather than daisy-chained connectors
- OPP, OVP, UVP, SCP, OCP and OTP protection

Questions
Before you buy
Is this enough power for my build?
It is a 1200W supply rated 80 Plus Platinum. Add up what your parts need - the graphics card is usually the biggest single draw, and every card we sell lists its recommended system wattage - then leave headroom above that figure. A supply running at roughly half its rating is quieter and lasts longer than one held near its limit.
Is it modular?
It is Fully Modular. Fully modular means every cable unplugs, so you only fit the ones you need; semi-modular keeps the motherboard and CPU cables attached and makes the rest optional; non-modular has them all permanently fixed. It is a tidiness and airflow question rather than a performance one. Never reuse cables from a different supply - the pinouts differ between brands.
Is it in stock, and when will it ship?
Yes - this one is in stock. Order before 12:00 on a working day and it ships the same day; after that it goes out the next working day. We are open 09:00 to 16:30, Monday to Friday, so an order placed over a weekend or a public holiday ships on the next working day.
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.
