[SOLVED] Dell optiplex 790 sff

[Trigger12.T]

My dell optiplex 790 has an i5 2400 quad core what are my upgrade choices for this system

 

[Rogue Leader]

Not much, that case means you can only fit in a half height GPU, and the PSU means you can't put a good GPU in anyway. CPU wise you can get the i7 2700 if you can find one.

Whats your budget, in most cases you're better off going new than trying to frankenstein that thing together with good parts.

 

[Trigger12.T]

My budget is any thing around £150 for a CPU

Well you could probably find that i7 on eBay for less around that, but whats your goal? What is the system not doing now that you want it to do?

TBH spending that kind of money on that CPU is a huge waste

 

[Trigger12.T]

Some light gaming and overall better performance.

What games in particular.

The i7-2700 will only give you marginally better performance, it won't be huge, especially not in day to day operations.

 

[Trigger12.T]

As long as it can handle games like csgo for example without being under load it's fine and for day to day performance as long as it can handle some multitasking without slowing down dramatically it's fine.

Yeah it will be an improvement, if those are your needs it should do the job. Just don't expect miracles.

Personally i would save your money and build yourself something new based on the Ryzen 5 2400G, but you'll need to double your budget and then some.

OK for now I'll just see how my system runs with the GPU I'm getting and I'll rather save from there or upgrade the CPU depending on how it runs without an
upgraded CPU

What GPU are you buying?

 

[Trigger12.T]

Zotac 1050 ti low profile 4gb

 

[Rogue Leader]

Ok that works, yeah the i7 may help you but prices are a bit up on them, best to wait and see how this does.

 

[Trigger12.T]

OK then will do ty for the help

Just a heads up, dell tends to put a wattage limit on the pci-e slots on sff and DT models. On my 9010 sff its 50w, on older ones it may be lower like 25w or 35w, so the 1050ti at 75w may not run at all. But many have reported success with the 790, so lets hope its not limited.

The best cpu for the sff 790 is the i7 2600 as it has the HD 2000 inbuilt graphics, the i7 2700 is HD3000 and won't work. I fitted it and those 8 threads make a big difference. I also fitted a zotac LP gtx 1050 ti and have been running it for almost 2 years with no issues. It may be just getting the juice it needs on the raiI but so far so good. I was a bit concerned with TDP due to the low wattage psu but even with 16Gb ram, an ssd and large HD it doesn't get near it's limits. I even tried a little bit of mining

 

[Trigger12.T]

OK thanks but the gtx 1050 ti is a 75 watt card and I've been told that the PCI-e connector only gives up to 35 watts so how is your GPU working.

 

[garycolman04]

It's working because it does. I can't say why, I'm no engineer.

That's mine running, plus you'll find a hundred other videos showing them working in 790s. It's a great card!

I had a Optiplex 790 SFF (i5-2400) with a Zotac GTX 1050 Ti 4GB in it for years. Ran just fine on the Dell 240W PSU (17 amp +12V rail). Gamed great at 1080p/60Hz.

About the best you can do for improved gaming with that PC until Nvidia comes out with their 1050 Ti replacement.

 

[maxamillionfeettall]

That's great, finding out that the watt limit on my 9010 sff was the reason for the crashes was the worst.

 

[Rogue Leader]

Yeah the 790 generally does not have the PCIe problem, many other Dell and HP models do though so it is worth researching.
