A gaming PC's power supply should match the graphics card maker's recommended wattage, with a native 12V-2x6 cable for recent NVIDIA cards. All five here are ATX 3.1 units with that cable.
We compared wattage, efficiency and warranty from each listing and Cybenetics data where listed; we did not test these units.

Best for
- Budget mid-range builds.
Skip if
- The maker gives no warranty, so look elsewhere if that figure decides it for you.
Why we like it
Its ECO silent mode keeps the 120mm FDB fan quiet at low load, and Japanese capacitors with LLC and DC-DC topology support long-term stability. Embossed modular cables are easier to route. Its embossed modular cables improve airflow and make routing simpler.

FSP's Hydro Ti Pro carries an 80 Plus Titanium rating, five PCIe 8-pin connectors plus a 12V-2x6 cable, and a 10-year warranty.
Best for
- Premium high-end builds.
Skip if
- If budget leads, the SAMA GT750 was cheaper at our last price check.
Why we like it
It is 150mm deep and holds a Cybenetics LAMBDA A++ noise rating. On rated output it ties with the NZXT C1000 Gold Core at 1000W. It matches the ASRock Phantom Gaming PG-750G and the MONTECH Century II 550W on warranty (10 years).
You get a titanium 80 plus rating here, which sets it apart from the MONTECH Century II 550W and its a gold 80 plus rating. No other pick in this guide offers a titanium cybenetics rating; compare the NZXT C1000 Gold Core, which has a platinum cybenetics rating. The FSP Hydro Ti Pro 1000W comes with a native 12V-2x6 cable, so a 16-pin card plugs in without an adapter.
It was the highest-priced of the 5 picks at the time of writing, so the case for it rests on what it adds over the NZXT C1000 Gold Core and the rest. The trade-off is native 12V-2x6 cable count; for more, the ASRock Phantom Gaming PG-750G offers 1.

How We Chose
Each pick was assessed across 4 criteria weighted for real-world use.
- Price
- We grouped picks by price at the time of writing.
- Standards
- We noted ATX version, 80 Plus and Cybenetics ratings.
- Wattage
- We compared rated output with NVIDIA's or AMD's recommended system power for the card.
- Build and warranty
- We checked depth, modular cabling, fan-stop modes and warranty length.
What to Look for in a Gaming PC PSUs
Key buying criteria so you get the right fit the first time.
Start from the card maker's PSU figure
NVIDIA and AMD publish a recommended total system power for each card, and partner cards often state their own. Treat that figure as the floor, then add headroom for a high-power CPU.
More wattage than you need does not harm anything; it mostly costs money.
Match the power connector
Most RTX 40 and RTX 50 cards use a single 16-pin 12V-2x6 (12VHPWR) plug, while many Radeon cards use two or three 8-pin plugs. A native cable avoids bulky adapters.
Push the 16-pin plug fully home and avoid a sharp bend right at the connector.
Use the warranty as a quality signal
Long warranties of seven to twelve years show how long a maker expects a unit to last. A power supply often moves from one build to the next, so the warranty matters.
Check depth and cabling
Deeper units can clash with drive cages or front radiators. Fully modular cables make routing easier in tight cases.
Compare efficiency ratings
80 Plus and Cybenetics ratings describe how much power turns into heat. Gold is the usual target for a gaming PC; Platinum and Titanium run cooler and cost more.
Prefer ATX 3.1
ATX 3.1 units are designed for the brief power spikes modern graphics cards produce and ship with the revised 12V-2x6 connector. Older units can still work, but check the maker's guidance for your card.

Frequently Asked Questions
Can I use the 16-pin adapter that came with my graphics card?
Yes, if it is the maker's own adapter and every 8-pin plug on it is connected. A native 12V-2x6 cable is tidier and has fewer joins.
Can I use an SFX power supply?
Yes, if the case supports SFX and the unit meets the wattage and connector needs of your card. SFX units cost more per watt.
How much headroom should I leave above the recommended wattage?
The card maker's figure already covers a typical system. Add 100 to 150W if you run a high-power CPU or plan a bigger card later.
Can I reuse the power supply from my old PC?
Only if it meets the card's wattage and connector needs and is still under warranty or in good health. Very old units lack modern connectors.
Is an ATX 3.0 power supply still fine?
Generally yes. ATX 3.1 mainly revises the connector to 12V-2x6 and relaxes some spike requirements; check your unit's cable is rated for your card.
Does a Platinum unit save much on electricity?
Only a little for most gaming PCs. The main gains are less heat and often a quieter fan.
Bottom Line
The ASRock PG-750G suits most mid-range gaming PCs, and the NZXT C1000 Gold Core covers high-end cards. The SAMA GT750 is the budget 750W unit, the MONTECH Century II 550W suits entry-level builds, and the FSP Hydro Ti Pro is the Titanium pick.
