Buying Guide: Things to Consider for Your Power Supply

Our review already knows that the GTX 1080 ti is right up there with the best graphic cards in the business. It’s a core component serious gamers need because it provides an incredible gaming experience.

That’s one of the main reasons it needs a suitable power source to keep it running smoothly to guarantee the best performance possible.

When you’re searching for the best one for your rig, consider the following factors:

– Wattage

Wattage is a top factor to consider, and the GTX 1080 ti requires a minimum of 600 watts to perform safely and up to standard. You might go higher than that, but you should be careful not to cause an increase in your energy bills.

However, experts recommend keeping the wattage between 600 and 800 watts of power.

– Cooling System

For gaming setups, one of the biggest issues to contend with is overheating. Many components work together, drawing power towards one goal – the best performance. At a high capacity, it’s no secret that the power supply goes full circle, leading to overheating and malfunctions.

For effective cooling, the fan is an essential part of the power supply to consider. The fan keeps the power supply running smoothly and without interference. The bottom line is that the fan system must detect and prevent issues that lead to overheating.

– Design

The design of any power supply needed for GTX 1080 ti should have a reasonable look. Take note of the design and the features of the power supply. If you have a more compact design, it has the advantage of fitting into your setup without hassles and will be less inclined to overheat.

To that end, our review team recommends modular or semi-modular designs. Such designs help you use only the necessary cables. That way, you get to store other cables you don’t need or remove them from the power supply. It deals with clutter, increased airflow, and saves you a lot of space.

– Efficiency

For any power supply you want, efficiency is a key factor. With higher efficiency, the better and smoother the performance. You also get a more stable power supply.

For your GTX 1080 ti, you should be looking at a power rating of 80+ Gold, 80+ Platinum, or 80+ Titanium. Anything lower than this ranking will be unable to keep up with the graphics card, which means low functioning capacity.

– Energy-Saving Operation

When you’re in doubt about the amount of wattage, it’s best to angle for more rather than less. It’s better to have enough power than force the components of your device to struggle and potentially get damaged.

The best idea is to look for power supplies with eco-friendly and energy-saving operations. They won’t waste electricity and will reduce operating costs.
