700W-750W Power Supplies

What to look for in a 700W–750W power supply

Though simple, a power supply unit has a lot to consider as you’re digging into its specs.

• Wattage capacity: You’ll find all the supplies in this range are rated for a mid-tier amount of headroom.
• Form factor: Are you looking for a larger ATX PSU or the more compact SFX technology?
• Connector support: Check the PCIE and EPS connector compatibility.
• Efficiency ratings: All CORSAIR power supplies are rated within Cybenetics or 80 Plus efficiency ratings.
• Modularity and design: Do you want a modular, semi-modular or non-modular power supply? What do you want your PSU to look like?

Is a 700W–750W power supply good enough for a gaming setup?

How much wattage you need for your PC really is a particular question that relies on knowing a lot about your setup—like what components you’re going with, what GPU you’ve opted for, and more. While no one can give you a blanket recommendation without knowing your full component array, we do offer a handy PSU Calculator tool which provides instant feedback on general wattage requirements for your PC setup. PSUs operate at their best when they are at a lower capacity than their max, so while you can push the units for heavier loads, it’s important not to plan to do that every time you turn on your system.
