Antec Atom v450W
Power Supplies
Antec Atom V 450W — compact 450W desktop power supply with a stable +12V rail (~37.5A), built for office PCs, HTPCs and budget 1080p gaming systems.
Product Details
Overview
The Antec Atom v450W is a 450-watt desktop power supply aimed at budget and everyday systems. As a 450W unit it delivers roughly 37.5A available on the +12V rail (450W / 12V), which is where the CPU and GPU draw the bulk of their power. That makes the Atom v450W a sensible choice for office machines, home theatre PCs and entry-level gaming rigs that don’t need high-end GPU power.
Performance & compatibility
In practical terms a 450W PSU comfortably supports modern 65W desktop CPUs (for example many Intel Core i3/i5 or AMD Ryzen 3/5 processors under typical load) paired with low- to mid-range graphics cards. Expect reliable operation with integrated graphics or discrete cards like the NVIDIA GTX 1650 / GTX 1650 Super and similarly low-power AMD cards for 1080p gaming at medium-to-high settings. High-end cards (RTX 3060 and above, RTX 3070/3080-class) commonly have 200W+ peak draws and the recommended system PSU sizes start at ~550–750W, so this unit is not intended for those builds.

Who this PSU is best suited for
The Antec Atom v450W is ideal for South African customers building a reliable, budget-friendly desktop: office and school PCs, compact home theatre builds, or gamers running 1080p with low- to mid-power graphics cards. It’s not matched to power-hungry, high-end gaming or workstation GPUs — for those, choose a higher-wattage, higher-efficiency supply. Best suited for users who prioritise cost-effective, stable power for everyday computing and light gaming.
