PSU compatibility with my Desktop

Lewis James · Sep 29, 2013

Hey everyone, I have this computer: http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=c03511113&lang=en&cc=us&taskId=101&contentType=SupportFAQ&prodSeriesId=5295969&prodTypeId=12454
And I was wondering if this PSU would work with it: http://www.ebuyer.com/393120-corsair-cx-series-cx750-atx-power-supply-750watt-80-plus-bronze-certified-cp-9020015-uk
Also one more thing to add, would the computer and PSU work with the Radeon 7850? Thanks to everyone who answers

For the PSU, get this one instead: http://www.ebuyer.com/257232-corsair-tx-650w-psu-80plus-bronze-certified-cp-9020038-uk

That one has better quality, and you don't need 750W. 650W will be more than needed, even, but if you later on decide to upgrade you can carry it over.

The Radeon 7850 will work, although it's PCIE 3.0 and the motherboard is 2.0.

yes, that psu will work. and yes it all will work with a hd7850

Kelthar :

OK, the reason I chose is so I could upgrade my CPU eventually too. Do you know if my computer would overheat with it? Because I am looking at getting quad core, and I really don't want to be changing my case?

Kelthar :

Also how much performance would I lose since the motherboard is PCI 2.0?

Kelthar · Sep 29, 2013

You'll most likely have to change the motherboard because of a different socket, depends on the CPU.

No, the case won't overheat (at least not to dangerous levels) as long as you keep stock settings (no overclocking).

But it is a bad case for gaming, because it has only one fan in the back (or even no fans at all), so airflow is bad.

And about performance loss, it won't be any. The card on its own won't be able to saturate PCIE2.0. PCIE3.0 is a *must* for SLI/Crossfire (two or more cards), though, because then PCIE2.0 will bottleneck.

Kelthar :

Don't worry, I have most of the CPU planned out I think. I think I will go for the A10 6800K which works I think? Yeah, I'm not too surprised its bad, and I have no plans of overclocking :3 OK, I don't really want to be using two cards at once either

Since you quoted my unedited post, I assume I didn't edit it on time, so here is what I added:

"And about performance loss, it won't be any. The card on its own won't be able to saturate PCIE2.0. PCIE3.0 is a *must* for SLI/Crossfire (two or more cards), though, because then PCIE2.0 will bottleneck."

If you don't OC, you won't have *any* issues. But you should definitely get a better case if temperatures turn out to be too high (GPU and CPU should stay below 75ºC).

if you're going to get a hd 7850 don't get an A10... get an Athlon II x4 750k or an Athlon II x4 760k. they're cheaper and will do the same job for you on the processing end of things.

And I won't have to change my motherboard or anything for that?

Kelthar · Sep 29, 2013

Socket is FM2 so no, you won't.

If socket is the same as the motherboard, it's compatible.

Kelthar :

OK, thank you very much for that sir
