LAN party prep means a PC that boots reliably at a friend's house and survives transport, so the power supply has to be dependable and right-sized, not oversized for show. Three tiers let you match PSU spend to your GPU and how often you travel with the rig.
Quick Answer
For LAN party preparation, budget on a 550W 80 Plus Bronze PSU around R900, balanced on a 650W 80 Plus Gold unit near R1,500, and premium on an 850W Gold modular PSU around R2,800 at Evetech. Size the PSU to your GPU: a 650W Gold unit covers an RTX 4060-class card with headroom for a LAN trip.
Budget Tier: 550W Bronze
A 550W 80 Plus Bronze PSU (about R800 to R1,000) powers a Ryzen 5 and an RTX 3050 or 4060 for 1080p LAN gaming. It is the floor for a transportable rig: reliable, affordable and enough for entry GPUs. Prefer a known brand over the cheapest no-name, because a PSU failure at a LAN ends your night.
Balanced Tier: 650W Gold
A 650W 80 Plus Gold PSU (R1,400 to R1,700) is the LAN sweet spot, covering an RTX 4060 or 4060 Ti with headroom and running cooler and quieter on the trip. Gold efficiency and a quality build reduce the chance of an awkward shutdown when the rig is jostled into a new spot. This suits most LAN builds.
Premium Tier: 850W Gold Modular
An 850W Gold modular PSU (R2,500 to R3,200) is for a rig with an RTX 4070 Ti or higher, or one you plan to upgrade. Modular cables make packing and reassembly at a LAN faster and cleaner, and the headroom handles power spikes from a strong GPU. For mid-range cards, it is more wattage than needed.
FAQ
What PSU wattage do I need for a LAN rig?
Match it to the GPU: 550W suits an entry card, 650W covers an RTX 4060-class GPU, and 850W is for an RTX 4070 Ti or higher. Add a little headroom for transport reliability and future upgrades.
Is a modular PSU worth it for LAN parties?
Yes if you frequently pack and unpack the rig, since modular cables speed up tidy reassembly at a venue. For a rarely-moved build, a non-modular unit saves money with no real downside.
Why does PSU brand matter for transport?
A jostled rig stresses connections, and a quality PSU with stable output handles that far better than the cheapest no-name. A reliable Gold unit reduces the risk of a shutdown mid-LAN, which is the last thing you want.
