19V 150W AC Adapter for Toshiba Qosmio X505-Q830

This 19V 7.89A 150W adapter replaces the original PQX33U-00K00H power supply for the Toshiba Qosmio X505-Q830. It accepts 100V to 240V input at 50 to 60Hz for worldwide use. The 5.5mm by 2.5mm connector also fits ports sized 5.5mm by 2.1mm. The unit is supplied new in black.

Continuous 150W delivery with wide-range input

The adapter maintains a steady 19V 7.89A output up to its 150W rating during extended charging sessions. Its 100V to 240V auto-switching input handles voltage variations without interruption. The black enclosure dissipates heat passively while powering the laptop and charging the battery simultaneously. OEM-compatible regulation protects the notebook’s internal power rail.

Verify connector fit and polarity before ordering

Confirm the laptop requires exactly 19V at 7.89A and that the barrel port accepts a 5.5mm outer diameter with a 2.5mm or 2.1mm inner pin. Check that the original part number matches PQX33U-00K00H or the model is listed as Qosmio X505-Q830. Buyers needing a different voltage, higher amperage or an alternate connector size should select another adapter.

Questions about this item

How much heat or noise does the 150 W adapter produce when running all day?

The unit has no fan and no moving parts, so it runs silently; warmth is normal for a 150 W brick but stays within safe limits.

What must I already own for this adapter to power my laptop?

You need a Toshiba Qosmio X505-Q830 or another model that accepts 19 V 7.89 A through a 5.5 mm × 2.5 mm barrel jack.

Will the 5.5 mm × 2.5 mm plug work with the older 5.5 mm × 2.1 mm port on my spare machine?

The connector is listed as compatible with both 2.5 mm and 2.1 mm centre pins, so it should fit either port.
