Hi I currently have an HP Prodesk 400 G4 Microtower PC and it apparently only came with the 180w version of the PSU. I have a GTX 1060 6GB GPU and an i5-7500 CPU which barely hang on in some games but in others it works and i'm just tired of the constant shutting off when I load into some games and some I just can't play anymore 🙁


I've had the PC for a year or so and I'm just wondering what PSU will fit into my case and work with my CPU and GPU. I'm very new to this PC stuff and don't have a lot of money to spend.

Most likely none of standard PSUs, by size and connectors.

If your computer is the one shown in this video, you've got a very small proprietary power supply with "special" HP power leads.

A standard more powerful ATX PSU is twice the size and comes with incompatible power connectors.

With HP and Dell computers, the best place for help is often their community web sites, as a quick search revealed.

You could try a 310W HP 922458-001 PSU:-

You might have to buy a second hand PSU. Some people will warn strenuously against buying used PSUs on eBay, but if you can't find a brand new unit, it may be your only option, unless you buy a new PC. Try to get a 3-month warranty if second hand.

I've bought slightly larger TFX PSUs second hand and risked them in old builds. They all worked fine, but my half dozen working PSUs are no guarantee others will be OK. An old PSU could die at any time.

If you're unlucky and buy a faulty PSU, it could damage your computer. Difficult to test in isolation unless you have a multimeter plus the necessary skill and understanding to perform such tests.

Plug it in, check all connections, switch on and keep your fingers crossed. It's up to you.

I'd check with HP to see if they supplied any GPU cards requiring a 6 or 8-way PCIe power lead for your PC. If not, they may not have a suitable PSU.

Inexpensive pre-builts from HP and Dell are often designed for wordprocessing tasks in offices, not playing games.

The clue is in the title of the PC. If a Dell or HP doesn't have the word 'Gaming' in the title, it's probably not intended for games.

and don't have a lot of money to spend.
Consider selling your PC (but not the 1060) and find a more capable second hand system with a 500W+ PSU. Make sure the PSU has the necessary PCIe power cables and is big enought to hold the GPU.
