Is a 200W PSU enough?

[Jyadel]

So I'm planning on doing a lower power, lower spec system.  It'll be (at most) a 65W chip like the Ryzen 5 3600 and a 75W GTX 1650.  Those combined are 140W at peak.  Would a 200W HDPLex PSU be enough when accounting for those two components as well as others like the MOBO/RAM?  Oh, and I won't be doing any overclocking.

PLEASE DO NOT USE A 200W PSU. At least 400W, they are pretty cheap anyway. 200w is not a lot for a Ryzen 5 3600, and 200w gives you no flexibility.

Do you already have the PSU or something? If it's meant to be like a small form factor build and it doesn't need that much performance, you could always just use an APU on it's own with 3200mhz RAM

Not a great option, you don't want to risk your components over a cheap PSU. 

 

I suggest looking at this for guidance:

I recommend Tier B or higher, something like the Corsair CX450W (grey label) is a good budget option.

What PSU exactly ?

where do you even get a 200W PSU in 2020??

From a 15-17" laptop probably. Dell's standard laptop PSU's are 65, 90, 130, 180 and 240.

 

I've not seen a desktop PSU under 350w for a while, and generally OEM's like Dell and HP undersize their PSU's. They're "just barely enough" for the GPU that they come with and there's a risk of overloading it if you change the GPU to a more powerful one. That headroom is only enough for adding two hard drives at most.

Guys...

 

He said it's an HDPlex.

 

Jeez.

 

They're really good units.  But kind of pricey.

 

$65 gets you the 200W brick that outputs 19V.  Then you spend another $63 for the 19V to ATX adapter that they make (essentially a nice looking Pico PSU).

 

It's good if you have almost ZERO space for a normal PSU.  But if you have space for an SFX PSU, you'll spend half as much money.

What chassis are you using?  

 

The HDPlex would work, but it's about twice as much as what you could spend on a higher wattage SFX PSU (even though you might not need the additional wattage).

I'm using the InWin BM639.  The included 160W PSU is actually about the same size as the HDPLEX 200W so I figured it could be a solid replacement.

Oh.. Yeah.. That case.  Good luck with that.
