Questions about this item

Does the 10 ft cable reach a desk socket without an extension?

The adapter ships with a 10 ft power cord that plugs into any 100-240 VAC 50/60 Hz mains outlet, so a standard desk or floor socket is usually within reach.

Should I pick this 19.5 V 12.3 A unit for my Precision 17 7720?

Yes — the 19.5 V 12.3 A rating delivers the 240 W the Precision 17 7720 expects, and the connector matches the original barrel jack.

Will the 240 W rating hold up during heavy GPU loads?

The brick is rated for a continuous 240 W output with over-current, over-voltage, short-circuit and over-temperature protection, so it sustains full power under load.
