Antec ATOM V350 · Fixed-cable ATX power supply
Start with the power your system needs.
The ATOM V350 is a fixed-cable power supply listed at 350 W total output, with a 120 mm fan and a defined set of motherboard, CPU, graphics and drive connectors. Its +12 V reference is 25 A / 300 W, so match the complete rail and connector requirements of your PC rather than choosing by the total wattage alone.

Check the connections
Match each component to its own lead.
The listed cable set includes one 24-pin motherboard connector, one 4+4-pin EPS12V CPU connector, one 6+2-pin PCIe graphics connector, three SATA connectors and two Molex connectors. Compare these with the motherboard and graphics card requirements, and check cable reach and case fit before installation.
Plan the whole system
Capacity is one part of the decision.
The reference input is 230 V AC, 4 A, 47–63 Hz. Individual rail limits and the 350 W total limit apply together; the separate maximum ratings must not be added to create a larger system allowance. Thermal Manager fan control and OPP, OVP, UVP and SCP protections are described in the product reference. No measured noise, conversion efficiency or 80 PLUS certification is claimed.
Confirm the supplied unit’s label, physical fit and connector requirements before selecting it for a complete PC. Output capacity is not wall-socket consumption. Exact regional approvals, dimensions, efficiency certification and the Antec-to-ATOM supplied revision remain unverified.
