Buying PC hardware in Australia

Buying parts for a computer, whether for a new build or an upgrade, involves more than comparing specifications. This page explains in general terms how to plan a build or upgrade and check that parts work together, what changes when you buy second-hand, what the Australian Consumer Law gives you and how that differs from a manufacturer's warranty, what to check on power supplies, chargers and lithium batteries, how to avoid scams when buying parts online, how to wipe old drives before selling or recycling them, and how to recycle e-waste, with links to official Australian sources.

The guide

From planning a build or upgrade and checking compatibility, through electrical and battery safety, consumer law and scams, to wiping old drives and recycling what you replace.

Start with what the computer needs to do

Before choosing parts, write down what the computer is for: everyday use, study, office work, creative work, gaming or something else, and which programs it must run. Most software publishers list minimum and recommended system requirements, and these are a better starting point than general advice. Decide whether you are building from scratch, upgrading an existing computer, or buying a complete system, and set a budget for the whole job, including anything you need to replace at the same time, such as a power supply, cooling or storage. This page does not suggest particular parts or prices because no official Australian source does.

How the main parts fit together

A desktop computer is a set of parts that must match each other. The processor (CPU) has to suit the motherboard's socket and chipset, and the motherboard may need a firmware (BIOS or UEFI) update to support some processors. Memory has to be a type and speed the motherboard supports. Storage drives connect through particular interfaces, and the motherboard must have the right slots or ports. A graphics card has to physically fit the case and needs the right power connectors. The power supply has to provide enough capacity and the right connectors for everything attached to it. The case has to take the motherboard's size, and the cooler has to suit the processor and fit inside the case.

Checking manufacturer specifications

The reliable way to confirm that parts work together is to read each manufacturer's own specification sheets and support pages, not just a seller's summary. Motherboard makers commonly publish lists of supported processors and tested memory, along with firmware versions. Graphics card, cooler and case makers publish dimensions and clearances. Power supply makers publish ratings and connectors. Check the exact model and revision, because similar names can hide different specifications, and keep copies of what you relied on in case a part does not match its description.

Upgrading an existing computer

An upgrade is limited by what the existing computer supports. Check the motherboard's or system maker's specifications for the maximum memory, the types of storage it accepts, whether the power supply can handle a more demanding part, and whether there is physical room in the case. Many laptops and compact systems have parts soldered in place or limited upgrade options, so check before buying. Back up your files before opening a computer or changing a drive. Energy Safe Victoria advises not attempting to repair faulty electrical appliances yourself, and a computer's power supply should not be opened.

Power supplies, chargers and the RCM mark

The Electrical Equipment Safety System (EESS) is the national framework for regulating household electrical equipment, with a single compliance mark, the Regulatory Compliance Mark (RCM). Energy Safe Victoria says USB chargers, travel adaptors and power supplies must be registered and show the RCM on the product itself, and that registration of higher-risk equipment can be checked on the EESS website. The ACMA says overseas marks such as CE or FCC cannot be used in place of it. Energy Safe Victoria also warns that a power supply that needs a travel adaptor was not designed for use in Australia, and that an appliance's rating label should cover Australia's 230V, 50Hz supply.

Lithium batteries in laptops, power banks and UPS units

Product Safety Australia notes that most laptops and power banks contain lithium-ion batteries and that there is no mandatory safety standard for them. It advises buying from a reputable supplier, using the charger supplied or a compatible one designed for that battery, charging on non-flammable surfaces rather than beds, sofas or carpet, unplugging once charged, and storing devices in cool, dry places away from direct sunlight and parked cars. Stop using any battery, device or charger that is damaged, swelling, overheating, leaking or venting gas. Queensland's Electrical Safety Office also advises checking chargers carry the RCM. If a UPS or other device uses lithium-ion batteries, the same precautions apply.

New or second-hand

Second-hand parts can save money, but your rights and the risks are different. Product Safety Australia says most consumer guarantees do not apply to private sales between two people where the seller is not a business; only title, undisturbed possession and no hidden debts or charges still apply. Consumer Affairs Victoria lists signs a seller may really be a business, such as an ABN or company name, a high volume of items, or trading for years. Before buying, check recalls, read the listing and photos closely, ask how the item was used and tested, and inspect higher-value electronics in person if you can. Energy Safe Victoria suggests having second-hand electrical items tagged and tested by a qualified person.

Consumer guarantees and manufacturer warranties

The ACCC says consumer guarantees under the Australian Consumer Law apply automatically when you buy from a business and cannot be removed, for example by a 'no refunds' sign. Products must be of acceptable quality, fit for any purpose you made known, and match their description. A manufacturer's warranty against defects is an extra promise on top of these rights and does not limit or replace them, and the guarantees can last longer than the warranty. Extended warranties are optional, and the ACCC says businesses must not pressure you into one or mislead you into paying for rights you already have.

Repair, replace or refund

If a part fails, contact the business that sold it first. The ACCC says that for a major problem you can choose a refund or a replacement, and for a minor problem the business must at least offer a free repair; if it does not fix a minor problem within a reasonable time, you have further options. Businesses must not tell you to take the problem to the manufacturer or importer. Change of mind, such as finding a cheaper price elsewhere, is not covered unless the business has its own policy, which it must then follow. If the business does not resolve the problem, your state or territory consumer protection agency can give advice.

Buying online and from overseas sellers

The ACCC says all the usual consumer rights apply when shopping online, and that overseas businesses selling directly to Australians must follow the Australian Consumer Law, although getting a repair, replacement or refund from them can be difficult. You may not be covered if goods go to an overseas address first and are forwarded to you. On marketplaces, your rights are against the seller, not the platform. A parallel import keeps your consumer guarantees against the seller, but the ACCC warns the manufacturer's warranty may not apply in Australia and products may not suit local plugs or voltage. Keep receipts, listings and messages, and pay with a method that offers a dispute process.

Avoiding scams when buying parts

Scamwatch warns about prices that are unusually low or sound too good to be true, sites with no terms and conditions, ABN or privacy policy, reviews that are all positive or posted in a short time, and payee names that do not match the seller. Be wary of sellers who ask for payment by gift cards, pre-loaded cards, money orders, cryptocurrency or several different accounts, or who want you to move outside the platform. Check an ABN on ABN Lookup and do not assume the first search result is the real website. If you have been scammed, contact your bank or card provider immediately, stop contact with the seller, and report it to Scamwatch.

Wiping drives, then recycling e-waste

Before selling, giving away or recycling a computer or drive, the Australian Signals Directorate's cyber.gov.au advises backing up what you want to keep, removing the device from your accounts, performing a factory reset, and taking out removable storage; it notes solid state drives may need the manufacturer's own erasure steps and that data not securely erased can be recovered. The OAIC also advises wiping a device's hard drive before disposing of it. Do not put old parts in household bins: DCCEEW says the National Television and Computer Recycling Scheme is free for households and covers items such as computers, monitors, keyboards, mice and hard drives. EPA Victoria says Victorian landfills cannot accept e-waste, and South Australia's EPA reported e-waste landfill bans expanding from 1 September 2013.

Questions to ask before you buy

Plain questions worth putting to a seller, and checking against manufacturer specifications and official sources, before you hand over money for computer parts.

Does the manufacturer's specification confirm this part works with the rest of my system?

Check the exact model against the motherboard maker's supported processor and memory lists, the case and cooler clearances, and the power supply's capacity and connectors.

Will my motherboard need a firmware update first?

Some processors need a newer BIOS or UEFI version. The motherboard maker's support page lists which version is required.

Is the seller a business or a private person?

Consumer guarantees of quality and fitness apply when you buy from a business but generally not in a one-off private sale, including on online marketplaces.

Does the manufacturer's warranty apply in Australia?

A parallel import or overseas purchase may not be covered by the local warranty, although a business seller in Australia still has to meet the consumer guarantees.

For a power supply, charger or adaptor: does it carry the RCM, and is it made for Australia?

Ask for a photo of the rating label, check it covers Australian supply, and avoid power supplies that need a travel adaptor.

For a second-hand part: how was it used, has it been tested, and has it been recalled?

Search Product Safety Australia's recalls, ask about condition and testing, and inspect higher-value parts in person where you can.

For anything with a lithium battery: is it damaged, swollen or missing its charger?

Product Safety Australia advises not using batteries or chargers that are damaged, swelling or overheating, and using the supplied or a compatible charger.

How does the seller want to be paid?

Scamwatch warns about sellers who want gift cards, pre-loaded cards, money orders, cryptocurrency or payments outside the platform, and about prices that look too good to be true.

When I replace a part, how will I wipe and recycle the old one?

Follow cyber.gov.au's steps to erase drives before they leave your hands, then use a free drop-off point under the National Television and Computer Recycling Scheme.
