Is 450W Good Enough For This Build?

Hey, so I'm planning a small upgrade for my current system using an i5-8400, 16gb 2400 ddr4 ram, the stock cooler and just the usual hard drive as well as an acer mobo and case as well as a gtx 1050 2gb currently on a 450 watt power supply and I was wondering if the supply would be enough for a 1660 ti? I've been getting differing results on different websites so help would be appreciated, thanks!

450 Watts is enough for any PC short of a 2080 and i7, a friend of mine has a 1080 and Ryzen 5 3600 running off a Corsair CX450

I WILL find your ITX build thread, and I WILL recommend the SIlverstone Sugo SG13B

 

Primary PC:

i7 8086k - EVGA Z370 Classified K - G.Skill Trident Z RGB - WD SN750 - Jedi Order Titan Xp - Hyper 212 Black (with RGB Riing flair) - EVGA G3 650W - dual booting Windows 10 and Linux - Black and green theme, Razer brainwashed me.

Draws 400 watts under max load, for reference.

 

How many watts do I need? ATX 3.0 & PCIe 5.0 spec, PSU misconceptions, protections explained, group reg is bad

In my opinion it couldn't hurt to get a 500watt, just a little more juice. I can't run my i5 4950 and a gtx 780 on a 450watt.

Alright, thanks!

It's always good to know what PSU it is just for peace of mind, while 450w is enough not all 450w units are good enough to handle extra load.
