Hi Everybody

I have an HP Slimline S5-1020 (specs) (motherboard specs)

I wish to upgrade my stock 220w PSU to a 400w PSU. After contacting HP customer support by email, asking them which specs I should look for in a PSU upgrade, I received a quick and helpful reply telling me that I have to look for a "Micro-atx" type PSU.

Is that all I have to worry about?
With that information I looked for a Micro-ATX and found this one: Apollo 400

If I buy this, will it fit into my computer and be compatible with all of my hardware?

Also, If this isn't a good PSU to buy, which do you recommend with a budget of $100?

I want to upgrade the PSU to be able to handle a low-profile video card comfortably.
This will be my first hardware upgrade and makes me kind of nervous, I just want it to go without any problems.

I already knew my slimline would have limited options in terms of customization, but I think that this isn't too out of the question.
Thank You :)

You have a "slim" machine, you'll need a TFX or maybe mITX power supply, need to measure.

Thanks for the link

Apparently I need a Micro-ATX, but those ones are listed under "SFX12V".

I looked in their Micro-ATX section and found this one:

One of my main concerns is for the connectors to be compatible with my hardware.

HP only told me to look for a micro-atx...I'm not sure if there are other criteria to be met or not.
I'm new to this so I want to make sure I get it right

edit-
Wow delluser.
HP was steering me in the wrong direction!
Now I'm not even sure of which type I'm supposed to buy...

The more research I do into this, the more confused I get

Apparently these two units are very similar.
The Silverstone is supposedly a FSP oem anyways.
Either one would work.
Like delluser1 said i think it's time to physically measure your unit.
Do it right the first time don't take someone else's word for it.

This is too complicated for my understanding..
I might just buy the video card without upgrading the PSU

some are saying that the recommended wattage is exaggerated and there are low-end cards that will run on a 220w.
I do want to use it for gaming, but not for new games.

I'll look into which low power cards I can get
