850W of Gold-certified power | ATX 3.1 & PCIe 5.1 ready | Fully modular etched cables | Dual-ball bearing fan | 8-year warranty

The ASUS Prime 850W 80PLUS Gold Black Edition is a fully modular ATX 3.1 power supply built for high-performance workstations, all-round PCs, and gaming rigs that demand reliable, efficient power delivery. Dual 80 PLUS and Cybenetics Gold certification — achieved through low-ESR capacitors and premium components — means the unit operates at up to 92% efficiency, generating less heat and running quieter under load. A bundled 16-pin PCIe Gen 5.1 cable supports the latest GeForce RTX 50 and Radeon RX 9000 series graphics cards, with the ATX 3.1 standard accommodating power excursions up to twice the rated output for rock-solid GPU stability. Fully modular etched cables — built with tin-plated oxygen-free copper wire — flex easily during installation and run up to 50°C cooler than the safety limit, keeping cable management clean and your build tidy. Cooling is handled by a 135 mm fan on a dual-ball bearing setup rated to last up to twice as long as sleeve bearing designs. Six layers of protection — over-current, over-temperature, over-voltage, over-power, short circuit, and under-voltage — safeguard your entire system at all times. Backed by an 8-year warranty, the Prime 850W Gold Black Edition is a dependable foundation for any serious build.

I had an issue with my laptop and Anton was very professional and helpful. He offered after hours delivery for my laptop at no extra charge and was able to diagnose the problem and gave a solution all in less than a day. I’ll definitely recommend their services.

I serviced my laptop with CompuMaster that was working like a glorified typewriter with flat keys. Anton collected it at my house late afternoon and I had it the next day midday. Anton kept me informed throughout the process. The work was cost effective, the service was top- tier! If I had not shamed his hand, I’d be convinced he is AI! Service like this just doesn’t exist anymore… Do yourself a favour, call him for all your device needs - he’ll sort you out faster than you can say AI! Keep up the stellar work!!!!👏🏾👏🏾👏🏾

Anton really went above& beyond from the moment we first spoke to assist in sorting out an initial beep(Bios error) on my laptop. Ended up being a much more difficult job in total but he sorted it all. The laptop is running smoothly again - I will definitely use him again and recommend him

I needed ink for my printer and most suppliers around Centurion were out of stock. Anton was relentless in his search and went the extra mile to source the ink from Joburg when others couldn’t help. His persistence and willingness to assist were greatly appreciated. He was also quick to respond to both calls and online messages, which made the whole process easy and reassuring. The company was a little slow with the invoicing, but that’s understandable — Anton is clearly more of a hands-on tech person than an admin person! Overall, great service and a big thank you for your help. Highly recommended.

The service was extremely awesome and Anton who happened to be the one fixing my laptop went above and beyond to help me fix my laptop, charged me less than I was supposed to pay if I’m being honest, he even fixed things he honestly didn’t have to which is heart warming and made me feel extremely comfortable. Honestly the best service I’ve had with laptops by far
