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, sizes, connectors, and clearances all have to line up.
Match It to Your Budget
Work out how big a slice of your build budget this deserves based on how hard gaming and everyday performance leans on the power supply, then settle on the tier that weighs cost against headroom.
Plan for Upgrades
A sensible power supply pick leaves headroom to grow, so go with one that won’t choke a later upgrade and keeps your build useful for years.

Frequently Asked Questions
Does RGB add meaningfully to power draw?
No. Lighting across a typical build draws only 10 to 30W total, so size the PSU from CPU and GPU requirements as normal, generally 750W to 1000W with 30 percent headroom. The relevant concern is header capacity: a motherboard ARGB header is usually rated 3A at 5V, enough for roughly 15 fans.
How do I power a large fan and lighting hub?
Use a controller powered directly from a SATA or Molex lead on the PSU rather than daisy-chaining everything through the motherboard header. Ensure the supply has enough SATA connectors, as fully modular units often ship with fewer than builders expect once drives and hubs are counted.
Do RGB power supplies fit every case?
Units with lit fans or side panels are usually standard 150mm-wide ATX, but often 160mm to 180mm deep. Check case clearance, and note that the lighting is only visible if the case has a ventilated or open PSU shroud with a cutout, which many closed-shroud designs lack.
Do individually sleeved cables matter for looks?
They are the biggest visual improvement in a lit build because standard black ribbon cables absorb light. Use extensions or a vendor-made custom set matched to your exact unit; pinouts differ between manufacturers and using the wrong set can short components. Never reuse cables from a different PSU brand.
What warranty do RGB units carry?
Mainstream 80 Plus Gold RGB supplies typically offer seven to ten years, with the lighting covered for the same period. Because LED and controller failures are more common than power stage failures, confirm the warranty explicitly includes lighting rather than only the power electronics.
