Zalman ZM1000-EBT power supply review
As stated, this (Sirfa HPJ based) Zalman ZM1000-EBT (1000 Watt) comes Gold certified, that means it’s 90% efficient at 50% load (in the EU / 220V). Efficiency matters. The PSU itself is even 100% modular. Efficiency matters; years ago PSUs were as low as 70% efficient, meaning that 30% of the used power simply vanishes, whilst you are paying for it on that electricity bill.
