Compact 1U FLEX power supply

This Lemincrash ATX-350W unit fits the 1U FLEX form factor at 150 by 83 by 40 mm. It delivers 350 W maximum power from a 180 to 264 V input range and uses a single 40 mm fan with intelligent speed control. The 20+4 pin main connector supports standard ATX motherboards.

Suited for NAS and POS builds

Ideal for builders assembling NAS, POS or cash-register machines in Mini-ITX or other small enclosures that accept a 1U FLEX supply. The five protection circuits (over-current, over-voltage, over-load, over-heat, short-circuit) aid stability in always-on roles. Not for systems needing redundant or hot-swap power modules.

350 W headroom for low-power platforms

Comfortably runs typical embedded boards, a few drives and modest peripherals within the 350 W ceiling. The 10 A, 33 W auxiliary output covers standby or low-voltage rails. High-end GPUs or many-spindle arrays will exceed the available headroom.

Questions about this item

Does my case have room for a 150 mm deep 1U FLEX unit with a 40 mm fan?

The supply measures 150 mm deep, 83 mm wide and 40 mm high, so verify your chassis clearance matches those dimensions before buying.

Will the 20+4 pin main connector fit a motherboard that only has a 20 pin socket?

Yes, the 20+4 pin plug separates so the 20 pin portion mates with older boards while the extra 4 pins hang clear.

How can I confirm the fan is spinning under its intelligent temperature control after power-up?

Listen for the 40 mm fan; it should start at low speed and ramp up only when internal temperature rises, showing the auto-speed circuit is active.
