PC Gamer até $5.000,00

@LNPott @Kleber Peters @Phoenyx Eu fiz uns testes no Extreme Outer Vision. Com uns hardwares semelhantes já que o Ryzen 5 3600 e a vga RX 5700 ainda não estão na lista. Substitui o processador por um R7 e a Vga por uma Vega 64.

 

O resultado deu recomendações entre 600-620W.

 

Poderiam me esclarecer esta dúvida de como uma CX550 seguraria?

[Phoenyx]

Em suma, este site chuta os valores pra cima além de colocar um aging nos capacitores da fonte (reduz sua eficiência em 10% senão me engano).

O que você tem que ver é o consumo máximo do processador e da placa de vídeo no site do fabricante, e somá-los. O restante do equipamento (usuário comum) demanda pouca energia e pode ser praticamente desprezado.

@Phoenyx Entendi! Inclusive achei um post no https://www.anandtech.com/show/12056/best-psus que explicou direitinho essa questão! Vou de CX550 mesmo! Obrigado!

How Much Power Do I Really Need?

Overall, the best way to select a PSU is based on both objective (e.g. wattage, performance) and subjective (e.g. design, modular cables) parameters. This admittedly does require every builder to be capable of making at least an educated guess about the power requirements of the system. However, this is where our guide and advice come in.

Perhaps the biggest mistake that many users make in selecting PSUs is overrating the power requirements of their systems. It is not uncommon for people – even store salespersons and experienced builders – to recommend a 1kW unit to a user with just two (or even one) high performance GPUs. A system with a single CPU and a single GPU rarely requires more than 300 Watts. A modern Intel Coffee Lake-based system with a single AMD RX 570/NVIDIA GTX 1060 card will hardly reach up to 220-230 Watts, while it usually idles at 45-55 Watts. And even in a more extreme scenario - say the rather power hungry Core i9 9900K paired with a GeForce RTX 2080 Ti - is going to stop short of 600W even in pathological loads.

Meanwhile "wattage calculators", though an improvement from blindly guessing, are usually simple tools that get their numbers from the design power (TDP) specifications of components. The TDP of a component does not represent the actual power requirements of a component -  it's at best a broad guideline - and it also is next to impossible to place every single component of a system under maximum stress simultaneously. However, keep in mind that a PSU should operate at around half load for optimal performance. With that in mind, while the recommendations of the online tools and calculators may be overestimated, they're not overly so. Selecting a unit of the wattage they recommend is not usually a bad idea, as the recommendation usually is twice the actual power requirements of the system. The common mistake is that users usually seek to buy a significantly more powerful unit, thinking that having extra power helps, and end up with a severely oversized PSU for their system that will be both more expensive to purchase and unable to perform as it should.

If you can measure the actual power requirements of your system, keep in mind that you should not buy a unit that will frequently operate near its maximum capacity. Just as you would not run your car constantly near the red line, a PSU should not be under maximum stress for prolonged periods. A high quality PSU can withstand it, but just because it can does not mean it should. Again, all switching PSUs deliver their maximum efficiency at roughly 50% of their rated capacity. Running a PSU at over 90% capacity for prolonged periods of time will not only reduce its performance but it will also make it hotter, louder, and decrease its expected lifespan.

Eu diria que segura sim, mas se pensa em overclock, pode pegar uma mais robusta.

@Drohmar Perfeitamente isso.

Ficou bom, você comprou um HD externo, nao sei se você precisa de mobilidade com ele se nao pegaria um HD intern maior tipo 3 gigas!

Tá dhr mano

Só trocaria esse gabinete, parece não ter airflow frontal decente

 

Pegaria o gabinete Redragon Wheel Jack

[Drohmar]

@Trunka eu preciso de um. Por isso tive que pegar!
