Can an Optiplex handle my powerful insertion?

Recommended Posts

Posted · Original PosterOP

I recently purchased a $75 used Optiplex 390 (i5, 8gb, 500gb hdd, Windows 10) to use as a HPTC for my bedroom. After getting the Optiplex setup I realized I have a extra GTX 980 in my closet from a few years ago.  Installing the 980 in the Optiplex should work but the stock PSU is only 270w and the 980 recommends a 500w PSU.

 

I'm planning to order a 500w SFX PSU ($70) from Newegg but for the time being I'm wondering if I can just install the 980 now. This computer is just for web browsing on a single 1080p monitor so I don't think the 980 will ever needs full power. 

 

Do I run any risk of damaging components if I install a 500 watt GPU on a 270 watt PSU? or is there some sort of fail safe on the MB or PSU?

 

Thanks,

Mike

does it even have PCIe power cables to support a 980?


I WILL find your ITX build thread, and I WILL recommend the SIlverstone Sugo SG13B

 

Primary PC:

i7 8086k (won) - EVGA Z370 Classified K - G.Kill Trident Z RGB - Force MP500 - Jedi Order Titan Xp - The venerated Hyper 212 Evo (with RGB Riing flair) - EVGA G2 650W - Black and green theme, Razer branwashed me.

Draws 400 watts under max load, for reference.

 

Linux Proliant ML150 G6:

Dual Xeon X5560 - 24GB ECC DDR3 - GTX 750 TI - old Seagate 1.5TB HDD - Dark moded Ubuntu (and Win7, cuz why not)

 

EVGA G3 thread, BR/BT threadSeasonic Focus thread, S12II/M12II thread, Userbenchmark (Et al.) is trash explained, PSU misconceptions

That's a good point, I will go check. I do have a ton of extra cables from a Corsair AX1000 PSU from my gaming rig. The Optiplex has an extra 16x slot so I just assumed there would be enough female connections in the PSU.

do you mean you're gonna try using modular cables from your corsair unit on the optiplex unit?

Sorry I should have checked. I assumed the Optiplex PSU would be like my AX1000 in that there would be extra molex connections on the PSU. It's just a single wire harness with no extra connections unless they are inside the casing the PSU which I doubt. 

 

I guess I'll just have to wait then for the SFX PSU. Thanks for your time.

Get the Optiplex adapter for a Motherboard/PSU plug conversion (if needed) and swap it into another case for the GTX980?

Finding a cheap ATX case shouldn't be hard.. swap and enjoy.

 

Unless you want the SFF variant size.


Maximums - Asus Z97-K /w i5 4690 Bclk @106.9Mhz * x39 = 4.17Ghz, 8GB of 2600Mhz DDR3,.. Gigabyte GTX970 G1-Gaming @ 1550Mhz

Yeah it's a mini tower. It looks just like the 790 but the io is a little different. The connections all look like they will work. I thought I remember reading some people had trouble fitting a normal sized PSU in the mini towers.

 

If I had an extra ATX PSU I would try it. I think I might order the SFX because I hope to make mini ITX build in the future and could salvage it from the optiplex build when I'm ready.

Thanks, I skimmed the whole article. I didn't know that the older Dells could be fire hazards due to weird OEM connections. I think my Dell is a "newer" one. IT came with Windows 7 from the factory. I think it was built in '07 but I can't confirm if that's what the factory sticker numbers mean.
