Is 400W enough?

Is 400W PSU enough for intel core i3-6100,sapphire radeon rx460 2gb,8gb of DDR4 ram 2133 Mhz and msi h110m pro-vh motherboard

 

[raisonjohn]

Yes, 400W is enough as long as your PSU is from a reliable/reputable Tier 1 or Tier 2 brand/model/series.

This is probably not the case, but most likely enough power to run though.

Should be enough if it is from a well known brand.

What is the brand and model of the psu?

You can put all your components in here and it will tell you how much wattage you need

Also this is a good thread to explain the differece in quality between the psu's

My definition of a good power supply:

haswell ready (sleep states of newer CPUs)

should be 80+ gold, (with bronze it should be at least 450W for this system)

warranty more than 4years

at least 1x 8Pin PCIe, better two

^Not a good definition of good power supply.

You can disable sleep states in motherboard.
Difference between bronze and gold efficiency is 5% in ideal condition. Will be less in non ideal situation. With a 450w power supply you can even run a 1070 these days.

 

[helpstar]

That´s my definition where nothing could go wrong and will be future proof for upgrading to for example a RX480

I´m aware the sleep states can be switched off, if a future motherboard provides this option in the future
and you will have to do that manually, without knowing, someone could be frustrated

also energy saving is always a good thing 😀
(less heat)

5% are 20W lost energy in this case

50% usage:
bronze 340W usable
gold 360W usable

[sizzling]

There are Gold rated PSU's that use poor quality components or build quality, they just use an efficient design. That rating is not a good way of judging a PSU.

 

[RCFProd]

80 Plus ratio means nothing and shouldn't be factored in deciding which power supply is good or not.

 

[helpstar]

it´s a combination of all the things I wrote down. If there is a gold unit which gives you just 3 years of warranty, there is something odd

Thank you guys for your help!

In 50% usage all power supplies will output same wattage. Just lower efficient ones will pull more power from wall.

I don't get what you meant by bronze 340w usable gold 360w usable.

 

[helpstar]

That's the 5% difference between bronze 85% and gold 90% efficiency.

 

[RCFProd]

That's the 5% difference between bronze 85% and gold 90% efficiency.

Surely that's not how it works lol? It is based on how efficiently the power from the wall is used. It does not mean you're getting 85% amount of power from a 500 watts power supply for example.

More watts from the wall going into the power supply compared to what the power supply really needs = watts lost. For example your wall inputs 400 watts into the power supply but only 250 watts is used. That's where the effiency is determined. Or have I been wrong all my life?

would delete my dumb posts if I could

don´t know why I posted this b*******t
