Updating power supply

[SallyDarkvalley]

My computer currently has a 180 Watt power supply.  I would like to upgrade to a 300 Watt supply.  Could you suggest one that is compatible with my model?

Hi,

Open up you PC and measure the size of the PSU.  Post your results.

Why do you want to upgrde the power supply?

[SallyDarkvalley]

Thank you for the quick reply!

I can't get the measurements right now....  will post them tomorrow when I have access.   I don know the part # is 759049-001.

I want/need to add a graphics card.  The card I'm adding requires at least 300 watt power supply.

I suggest that you go bigger than 300 watts as this will give you more options for future upgrades or even a bigger more powerfull graphics card.

It is very difficult to get accurate measurements without removing the power supply from the PC.

As close as I can tell, it is 3 1/2" x 5 1/2" x 5 7/8"

Hi,

HP has a 300 watt PSU that will fit perfectly within your cabinet and it will not need any adapters.  That PSU should be large enough to get you to a graphics card such as the EVGA NVIDIA GTX 1050 TI.

Contact HP Part Surfer and ask for 759045-001.

Are there any 500 watt power supplies you can recommend?

Hi,

I suggest using a modular power supply in these small HP cabinets.

The Corsair CS550m would be a good choice.  Check the power plugs on your existing power supply in case you may need adapters.  It's on sale and with the rebate makes it's only $39.

EVGA makes a 500 watt power supply but it's not a modular model.  $39
