Power Supplies

Overview

The Antec Atom V450W (Used) is a 450-watt ATX power supply from Antec's Atom family. As a used, entry-level PSU, it delivers a continuous 450W output in a compact, standard ATX enclosure — designed for budget desktops, home theatre PCs and single‑GPU systems that don't demand high headroom.

Performance and technical notes

At 450, W the Atom V450 is built around a +12V‑centric design: most of its rated power is available on the +12V rail, which is what modern CPUs and GPUs draw from. That makes it well-suited to typical configurations such as a mainstream quad‑ or six‑core CPU paired with an entry to mid‑range GPU (examples: GTX 1650 / GTX 1650 Super / GTX 1050 Ti class). These combinations usually keep system draw well within safe limits for a 450W supply under normal gaming or productivity loads.

Entry-level PSUs like the Atom V450 often prioritize value and compactness over premium efficiency or modular cabling. Expect standard fixed cabling, an internal cooling fan for thermal management, and the basic protection features common to consumer PSUs (over‑voltage and short‑circuit protection are typical). As a used unit, performance depends on prior operating hours and care — a visual inspection for cable and connector condition is recommended before prolonged high‑load use.

Practical use cases

What it handles well: 1080p gaming on medium–high settings with single lower‑power graphics cards; office and school PCs; home theatre/media centre builds; and light photo or video editing workflows on timelines that don't rely on heavy GPU/CPU rendering. What to avoid: high‑end GPUs (eg, RTX 3060/3070 class and above) or multi‑GPU setups and heavily overclocked CPUs — those demand higher wattage and stronger peak current on the +12V rail than a 450W budget unit can comfortably sustain.

Specs summary

• Model: Antec Atom V450W (Used)
• Output: 450 watts continuous (ATX form factor)
• Design: Entry‑level, +12V‑focused power delivery (typical for mainstream desktops)
• Cabling: Fixed (non‑modular) cabling typical of budget ATX PSUs
• Use cases: Office/HTPC, budget gaming (single lower‑power GPU), basic home/office builds

Who this is ideal for

Ideal for buyers building or upgrading budget desktops, media centres and light‑gaming 1080p rigs that use a single low‑to‑mid power GPU and a mainstream CPU. Not recommended for high‑end gaming, workstation or multi‑GPU systems where a higher‑wattage, premium PSU is required.

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 Deepcool 750W is a 750‑watt ATX power supply designed to deliver stable 12V power for modern desktop systems. A quality 750W unit provides enough headroom for mainstream and high‑end single‑GPU builds, steady performance under load and room for modest CPU/GPU overclocking.

Technical notes and real‑world performance

750 watts of continuous output means the unit can reliably power systems whose combined CPU+GPU draw typically sits under ~650W while leaving headroom for peaks. Modern desktops put most of their load on the 12V rail(s): a correctly spec'd 750W PSU will supply the majority of its rating on the 12V line to feed CPUs and graphics cards. Power supplies also operate most efficiently near 40–60% load, so a 750W unit is often running in an efficient zone on systems that draw 300–450W.

In practical terms, a robust 750W supply is suitable for gaming at 1440p and for many 4K setups using a single high‑end GPU (for example RTX 30/40‑series or Radeon RX 6000/7000 cards) paired with a modern high‑performance CPU. It also gives content creators reliable power for editing and rendering workflows where sustained CPU and GPU use can otherwise stress lesser PSUs.

Specs summary

• Wattage: 750W continuous output
• Form factor: ATX (standard desktop PSU)
• Primary output: 12V rail(s) designed to feed CPU and GPU loads
• Typical protections on modern units: OVP, UVP, OCP, SCP and OTP
