Is 550W enough for the GTX 1070? (Quick Answer)

Is 550W Enough for the GTX 1070?

Graphics cards are one of the most crucial parts of your custom PC build. These computer components get juice from your power supply through power connectors. If you have a GTX 1070 graphic, you may want to know whether 550w is enough to power it.

550W is enough to power GTX 1070, as long as you have one card. On average, GTX 550W requires you to have a 450 to 500 watts power supply unit. However, if you are pairing GTX 970 and GTX 1070, 550W is not sufficient to power the two graphic cards.

This graphics card has a maximum graphics card power of 150 W and a maximum GPU temperature of 94 °C. Its built-in cooling system regulates operational temperatures for peak performance.

What to Consider When Buying a PC Power Supply Unit

Power supply units (PSU) deliver power to your entire computer system. With a broad range of options in the market, choosing the right one might seem like an overwhelming task. Below are the most important considerations to make when selecting a power supply:


PSUs deliver power to your computer through cables. Some have 24-pin motherboard connectors to power crucial components like the chipset, while others use PCI Express slots to provide power to GPUs. Power supply SATA connectors provide power to SATA storage drives, and 4-or 8-pin CPU connectors deliver power to your CPU.


Complex systems need high power requirements to run. Therefore, you should consider the hardware in your build before buying a new PSU. Err on the side of caution and select a power supply with a higher wattage for your build.


Although wattage is an important consideration when choosing a PSU, you should also consider power efficiency. Inefficient power supplies waste power and produces more heat, potentially reducing the lifespan of PC hardware. Most power supplies have built-in fans that dissipate heat and maintain peak operational temperatures. Look out for power supplies with higher “80 PLUS” ratings.

Since PSUs handle large amounts of power, their safety features are a significant concern. The best power supplies have built-in fail-safes that protect the PSU from power surges. Buy a PSU with functionalities such as over-voltage protection (OVP) and short circuit protection. It’s always safe to plug your computer system into a surge protector.

Form Factor

Ranging from ATX to SFF, various PSU form factors match your unique PC case. Modular power supplies have detachable cables that simplify your PC build experience.


Customization is the main appeal of PC building. Most power supplies have additional features like customizable RGB lighting that enhance your PC’s aesthetics.
