Yes personally i do not use those Power Supply Calculator.Because there not 100% reliable. I have been building computers over ten years now and never trust those Power Supply Calculator that's just my personal view, opinion.You are entitled to use them if you like. Measured power consumption - single card

System in IDLE = 99W
System Wattage with GPU in FULL Stress = 179W
Difference (GPU load) = 80W
Add average IDLE wattage ~10W
Subjective obtained GPU power consumption = ~ 90 Watts

Mind you that the system wattage is measured at the wall socket side and there are other variables like PSU power efficiency. So this is a calculated value, albeit a very good one.

One card - On your average system the card...

Never heard of that brand PSU before. From the limited research I've done, it's not well looked upon, and it seems it should be rated for 400w at most.

See this thread:

However, your build shouldn't pull more than 400w.

Ideally, change your PSU. Good brands are Seasonic, XFX, Antec and Corsair.

Here are some suggestions:

Don't hesitate to ask if you have more questions :)

The power supply is manufactured by one of the very best. ;) On your average system the R7790 requires you to have a 500 Watt power supply unit.
