Power Supply upgrade

[JamesHJ_87]

I have a  HP EliteDesk 800 G1 desktop i7 Q87 with a 320 watt power supply. Is it possible to upgrade this supply unit to something higher?

@JamesHJ_87,

Welcome to our HP User Forum!

Do you have the SFF (Small Form Factor) or the Tower desktop?

Kind Regards,

Thanks for replying. I have the tower version

@JamesHJ_87,

Thank you.  -Come to think of it, regardless of whether you have an SFF or Tower desktop, yes: you can upgrade your power supply.  The most effective and painless way, in my opinion, is to use a "24 Pin to 6 Pin ATX Power Adapter Cable for HP EliteDesk 800 G1" such as seen here: Amazon.com: COMeap 24 Pin to 6 Pin ATX Power Adapter Cable for HP Z220 Z230 SFF MT TWR Series 4000 6....  Installation is a breeze, it is safe, reliable and inexpensive.

I have applied this power supply upgrade method myself very successfully on two HP Compaq Pro 6300 SFFs primarily to be able to power much better PCIe 8-pin(s) powered graphics cards -see my link on page 5: Solved: Upgrading HP Compaq Pro 6300 SFF - Page 5 - HP Support Community - 8184303.  Since an SFF has less internal space to house a high(er) end graphics card than a Tower version, I had to park my graphics cards outside the SFF cases at additional expense, but this is something you probably don't have to worry about.

[EDIT:]  Mind you, I had to park the larger standard ATX 24-pin power supplies outside the SFF cases too, but perhaps you could find an ATX power supply that would fit inside your Tower case -you just have to make careful measurements (LxWxH) of your existing PSU space and compare that with available ATX power supply dimensions.

If you are interested to travel off the proverbial reservation like I did and have any other questions, please don't hesitate to ask.
