QUANTO DE ENERGIA GASTA UM PC GAMER POR MES?

Finance / cost-of-ownership takeaways (electricity cost modeling)

The video focuses on the electricity bill cost of running a gaming PC, emphasizing that a PSU’s rated wattage does not equal the power drawn from the wall.

Key concept: what determines wall power draw?

Actual wall power draw depends on:

• PSU efficiency (e.g., “80 Plus” ratings)
• PC workload (idle/standby vs streaming vs gaming)

Tickers / assets / instruments / sectors

• None mentioned. No stocks, ETFs, bonds, commodities, or other financial instruments are referenced.

Step-by-step calculation framework (as described)

The framework uses a simplified full-load scenario:

Assumptions

• The PC/PSU delivers 500W to the machine (example value)
• PSU is assumed 100% efficient (explicitly noted as rare)
• PC runs 8 hours/day
• Month length approximated as 30 days

Convert to kWh

1. Hours per month: 8 hours/day × 30 days = 240 hours

2. Energy (kWh): 500W × 240 hours ÷ 1000 = 120 kWh

Apply the electricity tariff

• 120 kWh × $0.50/kWh = R$60/month

Clarification

• This scenario is simplified and excludes taxes (“without tax”).
• Real consumption may be lower because the PC is not always at full load, and usage patterns vary (idle, standby, streaming, gaming, etc.).

Key numbers and explicit recommendations/cautions

Example values used in the model

• 500W load
• 8 hours/day
• 30 days/month
• Electricity price: 50 cents per kWh
• Result (pre-tax): R$60/month

PSU example

• A 650W PSU is mentioned as the narrator’s real PSU (“because that’s exactly the power supply I have in my PC”).

Efficiency guidance

• Recommends choosing PSUs with at least ~80% efficiency (references “80 plus efficiency labels”).
• Highlights that unused power is effectively wasted as heat, meaning you still pay for energy via the utility meter.

Cautions

• Real electricity use varies with workload; the PC doesn’t draw full power continuously.

Practical recommendation

• Use a smart plug / power meter to measure actual kWh over a month, then compute cost using the same kWh × tariff approach.

Disclosures / disclaimers

• No explicit financial advice disclaimer (the content is about energy cost, not investing).
• Notes the calculation is simplified and assumes 100% efficiency, which is rare.
• States the example cost is without tax.
