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 gaming and everyday performance 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
How do I choose wattage for a blackout build?
Colour does not change electrical requirements. Size by component draw with roughly 30 percent headroom: 650W for a mid-range system, 850W for an upper-tier GPU and 1000W or more for a flagship. An ATX 3.1 unit rated for 200 percent transient excursions handles modern GPU power spikes reliably.
Which cables and connectors should I check?
Verify PCIe and 12V-2×6 connector counts against your graphics card, plus one or two 8-pin EPS leads for the CPU. Only use cables supplied with that exact PSU model, since modular pinouts differ between brands and even between generations from the same brand, and mismatches can destroy components.
Will a fully black PSU fit my case?
All-black units follow standard ATX dimensions of 150mm wide by 86mm tall, with depth from 140mm to 200mm depending on wattage. Check case clearance and leave around 40mm behind the unit for cables. SFX versions measure 125 by 63.5 by 100mm for small form factor builds.
Do black sleeved cables improve the look?
Yes, considerably. Flat black ribbon cables are the cheapest tidy option, while individually sleeved black extensions give a fuller, more uniform appearance behind glass. Matte black cables in an unlit build can disappear entirely, which is usually the intended effect for a blackout theme.
What warranty should I expect?
Quality 80 Plus Gold units carry seven to ten years and Platinum or Titanium models up to twelve, reflecting the use of 105 degree Celsius Japanese capacitors. Because a PSU commonly outlives two or three builds, buying ATX 3.1 now avoids replacing a working unit purely for a new connector standard.
