I am wanting to upgrade my Power Supply on my tower from 180W to 400W. But I can't find one that is compatible with my PC. I was wondering if anyone could help. The cheaper the better.
https://support.hp.com/us-en/document/c05382582 Here is a link to my MOBO specs.
I am also buying this, I was wondering if there are any problems with it. https://www.amazon.com/MSI-GT-1030-2G-LP/dp/B071L4VKF6/ref=sr_1_1?keywords=GT+1030+msi&qid=158214353...
Thank You in advance.

Greetings,
Welcome back to the forum.
I am not a HP employee.
I have seen ATX power supplies and SFF power supplies. I am not sure what the dimensions of a uATX power supply would be.
I would measure the existing power supply and compare the dimensions to both a ATX part and a SFF part to see what fits.
Your PC has a Lubin motherboard (MB). The 24 pin power supply connection can cause problems with lengthy, dual slot graphics cards. There are also front panel connectors that may interfere with a dual slot graphics card.
The 1030 you are looking at may fit in your case and MB. This graphics card is only about six inches long. And it looks like it will not interfere with the front panel connections on the MB. A single slot card is you best bet.
Measure six inches along the x16 slot to see if you hit the 24 pin power supply connector on the MB.
Don't cheap out on a power supply. A cheap PSU can take down every component connected to it when it fails.

Hi Fergyboy,
You're very welcome.
A typical ATX power supply is 150 mm width, 86 mm height, and 140 mm depth (5.9 inches, 3.9 inches, 5.5 inches respectively).
An ATX power supply should fit in your PC's case if your measurements are accurate.
I would not buy the PSU in your link.
This alternative power supply by Corsair (Link) has a five year warranty and is semi modular.
There is always a chance a purchased component will not work in a given chassis or motherboard. Make sure you can return purchased product upgrades if they incompatible with your PC.

Hi,
Again, I have seen ATX power supplies and SFF power supplies.
Check the internet for a uATX power supply. Check uATX power supply measurements and compare to your power supply measurements.
The dimensions you provided in your previous post suggest ATX dimensions.

You're right, it is an ATX PSU. I've found one that works.
Final Question: My current PSU is rear-facing, and I was wondering how it would affect the temperature if I got the fan on the new PSU facing downwards. What do you think?
Thanks.
