myVolts LD-A450WL 12V 450W AT power supply
AT adapter board plugs straight into a 24-pin motherboard connector to deliver 12 V at 450 W with short-circuit and over-current protection
- TypeAT
- Direct motherboard plug removes 24 wires for cleaner builds
- 450W output from 12V input powers full desktop loads
- Over-current and short-circuit protection shuts down output on fault
- Compact board design saves case space without reducing power
- Multiple connectors include CPU 4+4 pin, two SATA, GPU 2+6 pin and DC5525
Direct-mount ATX adapter
The myVolts LD-A450WL plugs straight into a motherboard ATX24Pin connector and removes the usual 24-wire harness, delivering 450 W from a 12 V input. It fits compact ATX boards where a standard PSU would not sit, and the PCB construction keeps the profile low for tight cases.
Replaces a full-size ATX PSU
Swapping a conventional power supply for this adapter is worthwhile when chassis space is the limiting factor and the system draws no more than the rated rails. It is not suited to builds that need additional PCIe power connectors beyond the single 2+6pin, or that require multiple CPU power headers beyond the one 4+4Pin provided.
450 W across five rails
The unit supplies +12 V at 30 A, +5 V at 10 A, +3.3 V at 10 A, +5 VSB at 2 A and -12 V at 0.05 A, with short-circuit and over-current shutdown on the main rails. Headroom ends when combined load approaches 450 W or when more than two SATA devices, one graphics card and one CPU connector are needed simultaneously.

Questions about this item
What ATX connector and cable lengths does the LD-A450WL need to fit my board?
The board plugs straight into a 24-pin ATX socket and includes a 340 mm CPU 4+4-pin cable, a 340 mm graphics 2+6-pin cable, two SATA cables at 390 mm and 190 mm, plus two DC5525 leads at 320 mm.
How do I install the adapter and which step is often missed?
Seat the adapter board firmly into the motherboard ATX24Pin header, then connect the CPU, GPU and SATA cables; the step often missed is ensuring the 4+4-pin CPU plug is fully latched before powering on.
What protection features will eventually need checking or replacement?
Over-current and short-circuit protection on the +3.3 V, +5 V, +5 VSB and +12 V rails shut the output off when limits are reached; if a rail trips repeatedly, the adapter board itself must be replaced.
