Power Supply with Wire Buying scrap price

Introduction, Construction, Components, and Recycling Value

As long as a power supply satisfies the official Power Supply with wire acceptance standard, it is valued according to the price of this recycling grade. A brand name or high wattage rating does not automatically create a higher scrap grade. Ohata evaluates the physical construction, material composition, completeness, attached wiring and condition of the unit.

A computer power supply converts incoming AC electricity into regulated DC voltages used by motherboards, processors, storage devices, graphics cards and other components. Most desktop ATX power supplies consist of:

• A painted or galvanized steel enclosure

• An internal printed circuit board

• Copper transformers, inductors and coils

• Aluminum heat sinks

• Cooling fans and electric motors

• Capacitors, rectifiers, MOSFETs and control ICs

• An AC inlet, power switch and internal fuse

• Insulated copper output wires

• Plastic ATX, CPU, PCIe, SATA and peripheral connectors

The steel enclosure normally represents a considerable part of the gross weight. However, the main recycling value comes from the insulated copper wiring, copper-bearing transformers and coils, aluminum heat sinks, circuit board and smaller quantities of other recoverable metals.

Attached wires improve the material composition of this grade because they contain insulated copper conductors. The actual recovery value varies with wire gauge, cable length, transformer size, internal component density and the proportion of steel and plastic. For commercial purchasing, these variations are averaged within the Ohata classification. Qualifying units are therefore purchased at the Power Supply with wire grade price instead of being individually valued according to brand or wattage.

Power supplies may contain charged capacitors and other electrical hazards. They must never be opened, crushed or manually dismantled by untrained personnel. Units should be disconnected from electricity before handling and delivered intact whenever possible.

Power Supply no wire is classified under different buying conditions.

Ohata Power Supply with Wire Classification and Identification Guide

A qualifying Power Supply with wire unit should be recognizable as a computer or compatible electronic power supply with its principal output cable assembly still present.

The following characteristics normally identify this grade:

1. Complete power supply enclosure: The steel case, internal circuit board, transformer, heat sinks and other major components should remain inside the unit.

2. Attached output wiring: The unit must retain its original or substantial output wire assembly. Common connectors include 20-pin or 24-pin ATX, 4-pin or 8-pin CPU, 6+2-pin PCIe, SATA and four-pin peripheral connectors.

3. Recoverable internal components: The transformer, copper coils, internal circuit board and aluminum heat sinks must not have been removed.

4. Identifiable power supply construction: Desktop ATX units, proprietary OEM desktop supplies, certain workstation supplies and similar wired power supplies may qualify when their construction and recoverable composition meet the standard.

5. Acceptable physical condition: Ordinary scratches, light dust, faded labels and normal signs of use are generally acceptable. Severe burning, heavy contamination or destructive dismantling may result in rejection or separate evaluation.

Non-modular power supplies are the easiest examples to identify because their cable bundles pass directly through the enclosure and cannot be disconnected externally. Some semi-modular or modular units may require separate inspection. If their removable cables are missing, they should not automatically be represented as complete Power Supply with wire material.

Inspectors should use the following procedure:

• Confirm that the object is a power supply rather than an empty metal enclosure.

• Check that the main output wiring is present.

• Verify that the internal PCB, transformer and major coils have not been removed.

• Look for fire damage, chemical contamination, water saturation or excessive mud.

• Confirm that unrelated objects have not been added to increase shipment weight.

• Separate units without wires, empty cases, adapters, chargers and other grades.

• Keep qualifying material sorted before weighing and settlement.

Manufacturer labels are useful for identification, but the recycling classification is determined by the physical unit—not by the label alone. A 300W OEM power supply and a 700W retail power supply may receive the same grade price when both meet the same Ohata standard.

Recoverable Materials, Buying Standards, and Handling

The principal recoverable materials in this grade include:

Copper: Copper is found in output wires, transformer windings, inductors, coils, motor windings and portions of the internal circuit board. It is one of the most important value-bearing materials in this category.

Aluminum: Aluminum is commonly used for internal heat sinks. Some designs contain several heat sinks around high-temperature switching components.

Steel: The enclosure, screws, fan guard and certain structural parts are normally made from ferrous metal. Steel contributes significant weight but has a lower unit value than copper.

Printed circuit board material: The internal PCB carries ICs, capacitors, resistors, diodes, MOSFETs, connectors and solder. It may contain small recoverable quantities of copper, tin, silver and other metals.

Plastic and insulated material: Connector housings, wire insulation, fan blades and structural parts contain plastic. These materials usually require separation during mechanical processing.

Ohata buying standards generally require the following:

• The power supply must contain its internal board and major components.

• A substantial original wiring assembly must remain attached or included as required.

• The load must be reasonably clean and free from excessive mud, oil and foreign debris.

• Units must not be filled with stones, steel pieces, water or unrelated material.

• Severely burned, carbonized, smashed or hazardous units must be declared separately.

• Different recycling grades should be separated before delivery.

• Batteries and unrelated electronic equipment should not be mixed into the load.

For safe storage, keep power supplies dry and protected from rain. Use strong containers because steel housings are heavy and their edges may damage bags. Do not lift units by a single small wire or connector. Large quantities should be palletized or placed in durable boxes, cages or bulk containers.

Power supplies should not be intentionally broken open before delivery. Uncontrolled dismantling may expose charged capacitors, sharp steel edges, lead-bearing solder and contaminated dust. It may also remove recoverable components and cause the material to lose its original classification.

Comparison and Official Ohata Classification

The most important distinction is between a complete unit with wiring and other power supply-related materials.

Classification	Identification
Power Supply with wire	Complete PSU with internal components and substantial output wiring present
Power Supply no wire	Power supply body remains, but the principal output cable assembly has been removed
Empty power supply case	Metal enclosure with internal PCB, transformer and other valuable components removed
Power supply circuit board	Internal PCB removed from the housing and evaluated as board material
Loose insulated wire	Detached cable processed or purchased under an insulated-wire category
AC adapter or charger	External laptop, phone or equipment adapter; evaluated separately
Burned or contaminated PSU	Requires separate inspection and may be rejected
Broken or stripped PSU	Missing major parts or physically destroyed; may be downgraded or rejected

A unit should not be classified as Power Supply with wire merely because a few short wires remain. The principal cable assembly must be present in a quantity sufficient to identify the item as a wired power supply. Conversely, different brands, wattages and connector configurations do not need to be separated when they all genuinely meet the same grade standard.

Combining complete wired units with wire-removed supplies, empty cases, adapters or dismantled boards creates additional inspection and sorting work. Mixed shipments may therefore be downgraded, reclassified or settled by their actual separated composition.

Under the official Ohata classification principle, all accepted power supplies that meet the Power Supply with wire standard are purchased at the corresponding grade price.

Final classification follows the Official Ohata Classification and is confirmed through physical inspection. Missing internal components, insufficient wiring, severe fire damage, hazardous contamination, or deliberately added foreign material may affect acceptance and buying value. Confirmed classification, measured weight, and buying value are determined after inspection.
