The Best White Power Supplies for All-White PC Builds
Six white ATX 3.1 units from 650W to 1000W, compared on cable color, efficiency, warranty and fit for white and glass-panel builds.
By The PC Journal editorial team
11 min read6 products evaluated
A white build narrows the power supply field quickly, and not every white unit ships with white cables. We picked units whose listings describe a white housing, from 650W to 1000W, so you can choose by wattage first.
Our picks rely on the manufacturers' published details rather than our own testing, and the listing photos remain the best way to confirm cable color before you order.
Pick the wattage your graphics card needs, then compare efficiency and warranty within that range.

Alternative 850W White Unit5 of 6
MSI MAG A850GL PCIE5 White on Amazon (opens in a new tab)
The MSI MAG A850GL White is an 850W alternative with white housing and cables and a native 12V-2x6 cable.
Best for
- MSI-themed white builds that want 850W.
Skip if
- You want a fan that stops at idle; none is rated for this unit.
Why we like it
The white version carries a 5-year warranty, half the ASRock's 10 years, and it lacks a Cybenetics rating. It makes sense mainly for MSI-themed builds. It is 80 Plus Gold with a 5-year limited warranty, and the white finish suits light builds.
The compact body helps in smaller cases. Its fully modular design keeps cables to what you need. It matches the LIAN LI Edge Gold 1000W White on efficiency tier (Gold). Efficiency tier is its weakest area, and the ASRock Steel Legend SL-850GW White covers it better at Platinum.
Key dimensions & specs
- Form factor: ATX, ATX 3.1
- Efficiency: 80 Plus Gold
- GPU cables: 1× 12V-2x6
- Cabling: fully modular
- Warranty: 5 years
Pros
- 80 Plus Gold certified
- Native 12V-2x6 cable
- Fully modular cables
- White housing and cables
Cons
- No zero-RPM mode
- No Cybenetics noise class

Buyers who need a confirmed efficiency tier should compare it with the ASRock Steel Legend SL-850GW White, which offers Platinum.
Key dimensions & specs
- Form factor: ATX, ATX 3.1
- Fan: 120mm fluid dynamic bearing, zero-RPM mode
- GPU cables: 1× 12V-2x6
- Cabling: fully modular

How We Chose These White Power Supplies
Each pick was assessed across 4 criteria weighted for real-world use.
- Efficiency certification
- We compared 80 Plus and Cybenetics tiers, noting where a unit carries both.
- Physical fit
- We recorded form factor and stated length, which decide whether a unit fits your case at all.
- Fan and noise
- We compared fan size, bearing, semi-passive modes and listed noise certifications.
- Warranty and build
- We compared warranty length and listed component details such as capacitor ratings.
What to Look for in White Power Supplies
Key buying criteria so you get the right fit the first time.
Check the cables, not just the case
A white housing does not guarantee white cables. Check the product photos and cable list before buying.
If you plan to add sleeved cables, buy ones made for that specific model.
12V-2x6 is a socket change
ATX 3.1 replaced the 12VHPWR socket with 12V-2x6, whose shorter sense pins keep power off until the plug is fully inserted. The cable itself did not change.
Push the plug in until it clicks and avoid bending the cable sharply at the connector.
Size wattage from the card maker's guidance
Graphics card makers publish a recommended power supply wattage for each card. Start from that figure for your exact model and add headroom only if you plan a bigger card later.
More unused wattage does not make a system faster; it mainly adds cost.
Look for a fan that stops at low load
A semi-passive fan switches off when the load is light, so the power supply makes no noise during everyday tasks.
Not every unit has it, and a listing that doesn't mention it probably runs its fan all the time.
Compare warranty terms
A power supply often outlives several upgrades, so warranty length matters. The picks here range from five to ten years where the listing states a term.
If the term isn't listed, confirm it with the manufacturer.
Check depth against your case
Case manuals list a maximum power supply length. Subtract room for the modular plugs, which stick out of the back of the unit, and for any fan or drive cage behind it.
Most ATX units here are 140mm to 160mm deep; high-wattage units can reach 180mm.

Frequently Asked Questions
How do I know a power supply will fit my case?
Find the maximum PSU length in your case manual and compare it with the unit's depth, leaving room for the modular plugs.
Can I buy white cables for a black power supply?
Yes, but only sleeved cables made for that exact model. Generic cables may be wired differently.
Is a Platinum power supply worth paying more for?
Mainly for heavy, sustained loads or very quiet builds. For typical gaming, fit, connectors and warranty matter more.
Do I need an adapter for a 12V-2x6 graphics card?
Not with the picks here. Every unit offers a native 12V-2x6 cable or suitable PCIe connectors, so an adapter adds an extra plug for no benefit.
Are modular cables interchangeable between brands?
No. They fit the same sockets on your components but are wired differently at the power supply end. Mixing them can damage hardware.
What changed between ATX 3.0 and ATX 3.1?
Mainly the GPU power socket: ATX 3.1 uses 12V-2x6, whose shorter sense pins cut power if the plug isn't fully seated.
Bottom Line
The ASRock Steel Legend SL-850GW White is the best-specified white unit, with a Cybenetics Platinum rating and a 10-year warranty at a moderate price. The Corsair RM750e White is the choice for matching white cables at 750W, and the Lian Li Edge Gold 1000W is built to be seen through glass.
The Corsair RM1000e White covers 1000W builds, the MSI MAG A850GL White is an 850W alternative with a shorter warranty, and the SAMA GT650 White is the budget choice.
