Direct motherboard power

The myVolts LD-NAS200L is a 200W AT-type power module that plugs straight into the motherboard ATX and CPU connectors. It replaces a standard ATX supply and its cable loom with a compact PCB assembly fed by a single 12V DC source. Builders of small-form-factor, embedded or industrial systems gain a tidy internal layout without sacrificing the rails their boards expect.

Builders needing ATX rails from 12V DC

This board suits integrators powering Mini-ITX, HTPC, POS or industrial control hardware from an external 12V brick or battery. It delivers +12V, +5V, +3.3V, +5VSB and -12V with over-current and short-circuit shutdown. Systems that require an AT-standard soft-on signal, multiple EPS connectors, or higher peak current than 12A on the +12V rail should look elsewhere.

12A on the +12V rail

The +12VDC output is rated for a maximum of 12A, which sets the practical limit for CPU and GPU draw in the target platform. If the intended build demands more 12V current, the protection circuit will trip and shut the unit down. Match the load to this figure before committing to the LD-NAS200L.

Questions about this item

Which capacity should I choose for a small ATX build?

The LD-NAS200L delivers 200W total power with +12V at 12A, +5V at 10A, +3.3V at 8A, +5VSB at 2A and -12V at .05A, sized for mini ITX boards and HTPC cases.

What does the 200W rating mean once the board is plugged into my motherboard?

It means the adapter can supply up to 200W combined across all rails — 12V at 12A for CPU and drives, 5V at 10A and 3.3V at 8A for logic, plus 5VSB at 2A for standby — without exceeding the peak current limits that trigger over-current shutdown.

What connectors does the DC5525 interface support and what does it cap in practice?

The DC5525 jack accepts a 12V external brick; the on-board regulator then caps output at 200W total with the per-rail limits above, feeding one ATX24Pin, one CPU4Pin, four SATA, two IDE and the DC5525 pass-through.
