Microsoft Windows 11

My cpu model is HP Slimline Desktop PC 270-pOXX.

It has a Lubin Motherboard in it and has an integrated 180 W power supply (psu).

 

I want to upgrade it by putting a 300 or 400 W psu in it for a new gpu,

will it work with my motherboard?

 

And the size of my motherboard is 8.1x8.7 inches

Is it micro atx or mini atx?

@Shubhodep,

 

Welcome to our HP User Forum!

 

Let's give you a specific TFX (Thin Form Factor) 300-watt power supply alternative with PSU dimensions (LxWxH): ‎6.89 x 2.56 x 3.35 inches, see if that would fit/work for you: https://www.amazon.com/SilverStone-Technology-Computer-Connector-SST-TX300-USA/dp/B07PR7NVWX/ref=asc....

 

Hope this was helpful.

 

Kind Regards,

Take into account that with a 300w power supply , you can only use low-power models..
400w a little more!
but the small case probably not very well ventilated, may not be ideal..
So unless you just need a small, underperforming graphics card, you might have some issues.
