450W or 650W psu?

[SecertlyHappy]

Hello, I cannot figure out how much wattage do I need for a Ryzen7 2700X with a GTX 1660 super 6gb OC. Could anyone please help me out with making the right choice?

 

Edit:

I am building a mini-itx build, with only 2 additional fans, no RGB.

450W PSU or more will be fine. The 1660 Super only consumes like 125-150W at stock.

More to a PSU than just the wattage though. Did you have any particular units in mind?

Budget for a psu? a 450/550w unit is technically more than enough but again budget? and location?

what? drives and rgb strips and fans barely consume any power and OP's system consumes around 250ish watts at worst.

450 is more than enough but I would go for 550/650 because if you start adding fans (more than five), rgb and many drivers it will become close to the limit and that's not something I can recommend.

I got about a $100 to $120 budget for psu and I live in Canada. I have a 600W corsair 80+ gold psu selected, but trying to see if I can save a bit more money and go with a 450W corsair 80+ gold psu.

You can safely go for a 450 then but I would still go for 550 to keep PSU usage % on lower levels which means lower psu temps and less fan noise.

Well, right now I have a 600W 80+ gold corsair psu selected. So should I stay with my 600W psu then?

To name some, assuming that's 120 Canadian dollars, what psu are you looking at currently? as in like what model?

Looking at 600W 80+ gold corsair SFX psu right now.

450W 80+ gold corsair SFX psu and 600W 80+ gold corsair psu is what I am looking at the moment. There is a 60 dollar difference in price, so asking to see. If I can save the money, I could just buy the 450W psu.

[SupaKomputa]

450w is enough if you don't overclock.

550w is a safer choice.

That’s incorrect. A RM550x at 120% load will be quieter than a G3 at 64% load.

$60 is not worth it if you only use half of the power. go with 450w.

Are you ready to compare all the PSU's or you just remembered to pick a weird comparison?

Ah nvm you're building an itx system, then the sf600 and 400 afaik are decent and should power this system just fine, and yes 400w is enough for this system.

Ok, I see there are some people recommending that getting a 550W is 'safer'? What would increase my power consumption significantly in build?

Changing out the parts to more power hungry ones, HDD's or fans or rgb strips and other similar things do not increase power consumption by anything huge.

You are not understanding. You made a statement saying that a higher PSU wattage will lead to lower PSU fan noise. That is incorrect.

You'd be surprised. 1 fan can draw 6/7 watts, now multiply that by 6, now add a couple of hard rives, then add another ssd, then you can add a rgb strip, also connect your USB devices to the PC and for good measure charge your phone on one usb port, low wattage is a recipe for disaster and you should never go for just enough UNLESS you know you will never upgrade the system in any way shape or form.

yes, probably 5-10 watts for each parts.

Those consume very little power lol, not going to change the fact that 400w is enough for this system. and even if they did consume a fair bit of power, this system doesn't consumer more than 250ish watts.

 400 watts is not enough for a Ryzen7 2700X with a GTX 1660 super if you add 6 fans, hdds and rgb, on absolute full load the psu will be stressed to its core, you are one of those people that think that ram, cpu cooler and motherboard dont draw power too? Are you familiar with PSU rails?

 

A system with  Ryzen7 2700X with a GTX 1660 super can very well pull +400 watts under FULL load with very little effort without any bells and whistles.
