Is 450watt enough for gtx 1070 and i5 8400

Title says it all, its a prebuilt pc so please don’t suggest me to buy more. I can’t. I can however, look for a new one. So please tell me if its enough or not

Yes provided it is a good quality PSU. The 1070 is rated at 150W and the i5 at 65W so 450 is plenty.

Nvidia recommends a minimum of 500W though... but maybe they like to be cautious and build in some overhead since they don't know what else you are adding to the system.

you want a good 550w unit

In theory a 150 watt video card, 65 watt processor, about 60 for everything else or less.
275 Watts or 61% of a 450 watt power supply.
Some of the GTX 1070's use more power depending on the model.
If it was a high quality power supply then it should work but most prebuilts use low quality.

Bit slow on the reply but i would say 450w is enough but its pushing it i would suggest 550w at least 80+ bronze rated, i have the same set up a 1070 asus strix and an i5 8400 but i have a lot of LED fans in my case too and i chose 550w so i can upgrade in the future
