Some machines never spike at all — they simply sit at high draw for hours. A render queue overnight, a simulation that runs all afternoon, an export that finishes when it finishes. Sustained load is a harder job for a power supply than any burst, and it is what this unit is built around: 1300W continuous, Titanium efficiency so less of that becomes heat over a long session, and acoustics good enough that a machine working all night is not a machine you lie awake listening to.

What It Pairs With
A many-core processor and a serious graphics card, in a case chosen for airflow rather than for looks — sustained load is as much a cooling problem as an electrical one, and this unit can only stay quiet if the air around it is moving. If the machine runs long unattended jobs, an uninterruptible supply is worth costing in at the same time: the most expensive thing about a power cut at hour six is not the electricity, it is the six hours. Ask us and we will quote one alongside.
Who This Isn’t For
A machine used for a few hours of gaming in the evening never reaches the sustained load this was designed around, and the qualities you are paying for stay theoretical. Worth knowing too: this unit is built to the ATX 3.0 specification rather than 3.1, so if your build is defined by extreme transient behaviour rather than long steady draw, say so in the enquiry and we will factor that in properly rather than let you find out later.
Common Questions
What does continuous output mean?
It is the figure the unit will deliver indefinitely rather than in short bursts. For a machine that works for hours at a time it is the only number worth reading, and it is the one quoted here.
Is Titanium efficiency worth it at this size?
This is the case where it makes most sense. The efficiency gap is a percentage, so the bigger the sustained draw and the longer it lasts, the more actual watts it represents — as electricity saved and as heat that never reaches the room.
Is it still quiet at full load?
Quieter than most things delivering that much power, but not silent — nothing moving that much heat is. The design goal is that a machine working hard stays in the background rather than dominating the room.
