PC part upgrade / power supply question...

[reaume_23]

I am building a PC for my wife. I have a Pavilion 570-p023w with an

I5 7400
8gb Ddr 4
128gb ssd
1 TB HD
Stock H270 lubin motherboard

I am adding an R9 380.

In order to do this I have to upgrade to a bigger tower and upgrade the power supply bring the stick one is 150w. What type of power supply will I need to order? I want to make sure it comes with all the connecters I need to power the components / GPU. I'm try to keep it on the cheaper side if possible.

Thanks for the help!

That mobo appears to have standard power connectors, so pretty much any power supply would do. I'd recommend a good quality 550W.

As far as I can tell, your psu is a standard ATX psu.
Measure the dimensions.
The rear opening should be 150 x 86mm.
The depth of a ATX psu can vary from a minimum of 140mm on up.
Check how long your unit is.

A R9-380 needs two 6 pin pcie connectors, found on a typical 550w psu.
DO not go cheap on the psu.
Seasonic quality is tops, and the 550w focus is on sale:

That said, the R9-380 is a hot card and your case has very little ventilation.

I suggest a GTX1050ti which runs much cooler and needs no aux 6 pin power at all.
A 450w unit would be fine:

Or, you could use a stronger GTX1060 which requires only one 6 pin connector.

I'm actually replacing the case, going full size and will be adding fans so cooling shouldn't be an issue. The R9 will not fit in the stock case I have currently so a new case was a must.

Thank you guys for the help, it's much appreciated. I have done rebuilds and upgrades, but haven't had to order a power supply yet, so figured I would consult for some help to get the right stuff.
