How many watts does my gaming PC need?

Add up your components' draw — the GPU and CPU dominate — then leave roughly 20–30% headroom. A mid-range gaming build is usually well served in the mid-wattage range, while high-end GPUs push you into higher brackets. Sizing up keeps the PSU cool, quiet and ready for upgrades. Check your GPU's recommended wattage as a starting point.

Is 80 PLUS Gold worth it over Bronze?

For most gaming PCs, yes. Gold wastes less power as heat, so the unit runs cooler and quieter and costs a little less to run. Bronze is fine for budget builds, while Platinum and Titanium suit high-wattage or always-on systems. The efficiency gain pays back slowly, but the lower heat and noise are immediate.

Do I need a modular power supply?

It's not essential, but it helps. A fully modular PSU lets you connect only the cables you use, improving airflow and tidiness — worth it for a build with a glass side panel. Semi-modular is a good-value middle ground. Fixed-cable units work fine and cost less if cable management isn't a priority.

What connector does my new NVIDIA GPU need?

Recent high-end NVIDIA cards use the 16-pin 12V-2x6 connector (the updated 12VHPWR). An ATX 3.x-rated PSU is designed for these and handles GPU power spikes better. Older and mid-range cards use the standard 6+2-pin PCIe connectors. Always check your specific card's requirement before buying.

Can a power supply damage my PC?

A failing or low-quality PSU can, which is why a unit with proper protection circuitry matters — it shuts down safely on over-voltage, over-current or a short. A quality PSU is one of the cheapest ways to protect an expensive build. On South Africa's variable grid, pairing it with a UPS adds another layer of cover.

Does a PSU replace a UPS or surge protector?

No. A PSU regulates and protects power inside the PC, but it can't keep the system running when the mains cuts out. A UPS adds battery backup for power cuts and outages plus surge protection on the line. For full cover in South Africa, run a quality PSU and a UPS together.

What's the difference between VA-rated UPS units and PSU wattage?

They're different things. PSU wattage is the real power the unit can deliver to your PC's components. A UPS is rated in both VA and Watts and supplies battery backup during an outage. Size your PSU to your components' draw, and size a UPS to the total load you want to keep running.

Do power supplies come with a warranty in South Africa?

Yes. Every PSU from Evetech ships with local warranty and nationwide delivery, handled in South Africa. Quality units often carry longer warranties, which is a useful signal of build quality — check the product page for the term and keep your invoice for any claim.

Power Supplies (PSU) ⚡

The power supply feeds every part of your PC, so a good one keeps the system stable and protects the rest of your components. Pick a PSU with enough wattage for your build plus headroom, the right connectors for your graphics card, and an 80 PLUS efficiency rating you're happy with.

Size the PSU to your total draw — mostly the GPU and CPU — then leave roughly 20–30% headroom so it runs cool and quiet and has room to upgrade. 80 PLUS Gold is the mainstream sweet spot for efficiency and heat; Platinum and Titanium step it up for high-end rigs. For recent high-end NVIDIA cards, check for the 16-pin 12V-2x6 connector or an ATX 3.x-rated unit.

Evetech stocks PSUs from entry builds to flagship rigs, fully modular and semi-modular, all with local warranty and nationwide delivery. With an unstable grid in South Africa, a quality PSU with proper protection circuitry is one of the cheapest forms of insurance for an expensive build — pair it with a UPS for surge and outage cover.

How to Choose a Power Supply

Two questions drive the choice: how much power your build needs, and how clean and efficient you want that power to be. Add up your components' draw, leave headroom, then match the wattage, connectors and 80 PLUS rating. The points below cover what matters.

Add up your main components — the GPU and CPU are the big draws — then leave roughly 20–30% headroom. That keeps the PSU running cool and quiet, away from its limit, and leaves room to upgrade. A mid-range gaming build is usually well served in the mid-wattage brackets; high-end GPUs push you higher. Size up rather than down.

80 PLUS measures efficiency — how little power is wasted as heat. The tiers run Bronze, Gold, Platinum and Titanium, getting more efficient (and pricier) as you climb. Gold is the mainstream sweet spot for most gaming PCs. Higher tiers run cooler and cost slightly less to run, which suits high-wattage or always-on systems.

Fully modular lets you attach only the cables you use, which makes for a cleaner build and better airflow. Semi-modular fixes the main cables and makes the rest detachable — a good-value middle ground. Fixed-cable units are cheapest but leave spare cables in the case. For a tidy build with a window, modular is worth it.

Check that the PSU has the connectors your graphics card needs. Recent high-end NVIDIA cards use the 16-pin 12V-2x6 connector (the updated 12VHPWR); an ATX 3.x-rated PSU is built for these and handles GPU power spikes better. For older or mid-range cards, the usual 6+2-pin PCIe connectors are fine — match the card's requirement.

A quality PSU includes protections like over-voltage, over-current, over-power and short-circuit shutdown, which shield your components if something goes wrong. On South Africa's variable grid this matters — but a PSU is not a substitute for a UPS, which adds surge protection and battery backup during power outages. Run both for the best cover.
