Transparent arithmetic

Complete desktop allowance

Add your own confirmed amounts in GBP. Initial values are hypothetical allowances, not current UK offers. Keep VAT, delivery and included items consistent.

Each amount: 0–10,000,000 GBP. Blank values are invalid.

Total = all four amounts. Resolve unknown costs before treating the result as a complete quote.

Transparent arithmetic

Measured electricity scenarios

Use measured wall power and your actual unit rate. CPU TDP and PSU output ratings are not wall measurements. Standby, displays and standing charges are excluded unless included in your inputs.

Power: 0–10,000 W; combined hours: 0–24/day; rate: 0–1,000 p/kWh. Blank values are invalid.

Daily kWh = (active W × hours + idle W × hours) / 1,000. Annual variable charge = daily kWh × 365 × p/kWh / 100. Same daily pattern assumed.

Transparent arithmetic

Single-dimension remainder

Subtract a complete component dimension and explicit reserve from a documented case limit. One-axis arithmetic is not full compatibility approval; cables, brackets, fans and other dimensions still matter.

Limit and component: greater than 0, up to 10,000 mm. Reserve: 0–10,000 mm. Blank values are invalid.

Remainder = limit − component − reserve. Negative exceeds this limit; non-negative does not prove complete fit.
