What to check before placing an order — written by BestDealz sourcing analysts.

How to choose

Choose a PSU that matches your load, connectors and supply conditions before you compare lead times or sourcing class.

  • Right wattage headroom — Add the system’s peak draw and buy with sensible headroom so the PSU runs reliably without overstressing under gaming, workstation or always-on business loads.
  • Check connector set — Confirm the exact motherboard, CPU, GPU, SATA and peripheral connectors you need, because missing plugs or too few PCIe leads can stop a build or force unsafe adapters.
  • Match power input — Verify the unit supports South African 220V mains and, if it will sit in a rack or industrial environment, check whether single-phase or 380V 3-phase site power affects your wider setup.
  • Verify form factor — Check ATX, SFX or other size, cable length and cooling layout against the case, since a physically incompatible PSU creates fitment, airflow and maintenance problems.
  • Choose sourcing route — Use BestDealz Class A for local SA stock with 2–5 day delivery, Class B for factory-direct China orders with Trade Assurance and customs plus VAT included, or Class C for SA drop-ship supply with escrow protection.
Frequently asked
How much wattage should I buy for an office PC versus a gaming or workstation build?

Size the PSU against the full system’s peak draw, not just the CPU or GPU, and keep reasonable headroom for stability and future upgrades. If you are ordering for mixed fleets, standardise by use case to avoid underpowered units.

Will these power supplies work on South African power?

Most PC PSUs are intended for standard 220V mains, but you should still confirm the input range on the listing or datasheet before ordering. For larger projects, also check plug type, PDU compatibility and site power conditions.

What is the safest option if I need stock quickly in South Africa?

BestDealz Class A is the fastest route for urgent replacements or rollout jobs because it is local SA stock with typical 2–5 day delivery. Class C can also suit local fulfilment needs where you want escrow protection.

What should I expect on imports and compliance when buying factory direct?

With BestDealz Class B, customs and VAT are included and Trade Assurance helps reduce transaction risk on factory-direct China orders. For business procurement, also request the paperwork you need for internal approval, including any applicable SARS clearance, SABS-related checks and supplier BEE information where relevant.
