Power Supplies

Overview

The Antec Atom 750W is a 750 watt ATX power supply aimed at mainstream and performance desktop builds. With a 750W total output it provides enough headroom for modern single‑GPU gaming systems, streaming rigs and content‑creation PCs that use a high‑core CPU and one powerful graphics card.

Power delivery & reliability

This 750W unit focuses on the essentials: a strong +12V delivery to feed CPUs and GPUs, active PFC for cleaner power draw from the mains and standard protection suites (OVP, OPP, SCP, UVP/OVP and OTP) to protect your components under fault conditions. A thermally‑controlled cooling fan keeps noise down during light use and ramps only when the PSU heats up. In practical terms a 750W supply like this comfortably supports a modern Ryzen 5/7 or Intel Core i5/i7 paired with a single high‑end GPU (for example GPUs in the RTX 3000/4000 or RX 6000/7000 family) without immediate power bottlenecks for normal clocks and modest overclocks.

Real‑world performance

For South African gamers and creators this class of PSU is ideal for 1080p and 1440p gaming at high settings, smooth streaming while gaming, and snappy video editing of 4K footage on desktop timelines. It isn't designed for extreme multi‑GPU setups or heavy overclocking that pushes total system draw well beyond 700W, but it does give reliable, stable power for single‑GPU workstations and mainstream enthusiast builds. Expect steady operation under sustained loads with sensible thermal management and the electrical protections listed above.

Specs summary

• Wattage: 750W total DC output (as stated in product name)
• Form factor: Standard ATX desktop power supply
• Power delivery: Strong single +12V delivery suitable for CPU + single high‑end GPU systems
• Cooling: Thermally‑controlled fan for quiet everyday operation
• Protection features: OVP, OPP, SCP, UVP/OVP, OTP (standard protection suite)
• Power factor correction: Active PFC for cleaner mains draw
• Connectors: Standard motherboard and GPU connectors (24‑pin ATX, 8‑pin CPU/EPS and multiple 6+2 PCIe style connectors for GPUs)

Who this is best suited for

Ideal for South African PC builders who want a dependable 750W ATX supply for a single‑GPU gaming or content‑creation PC — gamers at 1080p/1440p, streamers and video editors who run one powerful GPU alongside a multi‑core CPU, without the need for multi‑GPU or extreme overclock headroom.

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.

Specs summary

• Brand & model: Antec Atom v450W
• Rated output: 450 Watts (total)
• Approx. +12V capacity: ~37.5A (450W / 12V)
• Target use: office PCs, HTPCs, small form-factor and budget gaming systems
• Typical workloads: everyday desktop work, video streaming, light-to-moderate 1080p gaming, basic 1080p video editing

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.

Overview

The Gamdias Kratos 500W is a 500-watt ATX power supply designed for budget and mainstream PC builds. Its 500W continuous output gives enough headroom for typical office systems, multimedia PCs and entry-to-mid-range gaming rigs. As a 500W unit it focuses on delivering stable +12V power which is what modern CPUs and GPUs draw from most heavily.

Performance and real-world use

A 500W PSU like the Kratos handles systems built around mainstream processors (for example Intel Core i5 / AMD Ryzen 5 class CPUs at ~65W TDP) paired with a single mid-range graphics card. Typical mid-range cards such as GTX 1660, RTX 3050 or even RTX 3060 (depending on the rest of the configuration and overclocking) will run comfortably when the overall system power draw stays below ~80% of the unit’s capacity. That 80% guideline helps keep temperatures down and improves longevity of the supply.

Good PSUs maintain tight voltage regulation on the +12V rail and low ripple, which is critical for system stability under load — particularly when you’re gaming at 1080p or doing light video editing. For everyday office work, web browsing and media playback the Kratos 500W provides more than enough headroom; for heavier 1440p gaming, multi-GPU setups, or sustained high-power workstation loads you would look to higher wattage, higher-efficiency models.

Specs summary

• Output: 500 Watts continuous
• Form factor: Standard ATX (fits most mid-tower and full-tower cases)
• Primary rail: +12V focused output for modern CPUs/GPUs
• Compatibility: Standard ATX motherboards; suitable for Intel and AMD systems
• Use cases: Entry-to-mid-range gaming, office desktops, home media PCs

Who this is best suited for

The Gamdias Kratos 500W is ideal for budget-conscious PC builders wanting a reliable, no-frills power source for 1080p gaming rigs, everyday productivity machines and HTPCs. It’s a sensible choice if you’re running a single mid-range GPU and a mainstream CPU, or upgrading an older system where a clean, steady 500W supply is all that’s required.
