Non Certified Power Supply Units

The non certified power supplies here are all from Ant Esports. They are ATX units with fixed (non-modular) cables and a 120mm fan. They run from the 400W VS400L through the VS450L, VS500L, VS550L and VS600L up to the 650W VS650L and 700W VS700L, alongside the 500W Ant Value Eco ECO500. Ant covers the VS series with a 2 year warranty and the ECO500 with 1 year.

Choose by wattage first. An office or home PC on integrated graphics runs comfortably on the 400W to 500W units. A system with an entry or mid-range graphics card needs more headroom. Ant pitches the VS650L at mid-tier GPUs, and the VS600L and VS700L sit either side of it. Check your card maker's recommended PSU wattage and its power connectors before ordering. Non-modular means every cable stays attached, so plan cable routing in smaller cases. The 450, 550, 650 and 750 watt filters narrow this list by output. For a high-end graphics card or a PC that runs under load for long hours, compare the certified units on the main Power Supply Unit page.

Frequently asked questions

What does non certified mean for a PSU? The unit carries no 80 Plus efficiency rating. More power is lost as heat than in a certified unit, which matters less in a lightly loaded office or home PC.

Which of these suits a gaming PC? For a mid-range graphics card, look at the VS650L or VS700L. Size it to the GPU maker's recommended wattage.

What is the difference between the VS500L and the ECO500? Both are 500W ATX non-modular units. The VS500L comes with a 2 year Ant warranty against 1 year for the ECO500.
