Questions about this item

How much usable power does the 700 W rating deliver to a typical gaming build?

The unit can supply up to 700 W continuously, with a single +12 V rail that keeps all CPU and GPU power on one rail for stable delivery under load.

What does the 80 PLUS Bronze badge guarantee for everyday efficiency?

Efficiency is at least 82 % from 20 % to 100 % load, and the supplier rates typical-load efficiency at 85 %, so less waste heat and lower running cost.

Will the 160 mm length and modular cables fit a standard mid-tower case?

At 160 mm long it matches the common ATX PSU envelope, and the modular design lets you connect only the cables you need for a cleaner interior.
