Builder’s Buying Guide: Fitting It Into Your Rig
Check Compatibility First
Before pulling the trigger, double-check the power supply suits your platform and the rest of your 2026 build — sockets, dimensions, connectors, and clearances all have to match up.
Match It to Your Budget
Work out how big a slice of your budget this deserves based on how much office and everyday work relies on the power supply, then settle on the tier that weighs cost against future headroom.
Plan for Upgrades
Picking the power supply wisely means leaving headroom to expand, so go with one that won’t choke a later upgrade and keeps your rig viable down the road.

Frequently Asked Questions
What wattage suits a typical office and light-use PC?
An office machine with integrated graphics or a small discrete card rarely exceeds 150W in normal use. A 450 to 550W unit is plenty and keeps you in a sensible efficiency band. Only go higher if the same machine doubles as an evening gaming rig or you plan to add a discrete GPU for video calls and light editing.
Does a more efficient PSU cut my electricity bill meaningfully?
At office loads the absolute savings are small, perhaps a few dollars a year moving from Bronze to Gold. The reason to buy Gold anyway is the better component grade, quieter fan behaviour and longer warranty, which matter more in a machine that sits a metre from your head for eight hours a day.
How much power does the PC use when asleep or off?
Modern units meeting current standards draw well under one watt in soft-off and only a few watts in sleep, so leaving the machine plugged in is not a real cost. If you want it lower, enable the deeper S4 hibernate state or switch off at the wall, but expect a slower resume.
Do I need a surge protector or a UPS?
A surge protector is the minimum and is cheap insurance for the whole desk. A small line-interactive UPS is better because it also rides out the brief brownouts and flickers that cause unsaved-work loss and file corruption. Around 600 to 900VA covers a typical office PC and a single monitor for several minutes.
Is a semi-modular unit enough for an office build?
Yes. Office systems need the 24-pin, one EPS lead and a couple of SATA connections, which is exactly what a semi-modular unit hardwires. You save money over fully modular and still leave out the PCIe and Molex chains you will never use, keeping the small chassis tidy.
