PSU for Dual GTX580

[Agility]

Hi there,

 

I dont know if thats the right sub for this but I'll post this here:

 

I've built a System a few months ago mainly for Music Production. I didn't got a new GPU and used an old GTX580 from Palit. Performance is not the best, but i am not gaming that much so thats okay.

 

Here are the Specs:

 

CPU: Core i7-8700K (OC@4.7Ghz)

RAM: 2x 8GB G-Skill Trident-Z 3200Mhz RGB

Board: ASUS Prime Z370-A

GPU: Single Palit GTX580 1.5GB 

Storage: 1x M.2 Samsung 960Pro / 2x Seagate 4TB 7.2k RPM (Onboard RAID)

PSU: Corsair RM750x

Cooling: Corsair Hydro H150i (3x Fans + 3x RGB Fans) / 1x Corsair LL120

Display: 27" 1440p Display

External USB-Devices: Steelseries Apex, Corsair M65RGB, Yamaha AG03, Roland TR-8, Arturia MiniBrute (Devices are always connected and on, no external PSUs) 

 

Since a few new Games are coming out I plan to get a new GPU. I can't afford a new 20XX-Series GPU for now so I decided to go for an used GTX580 from eBay and SLI it. I got that thing on the cheap (20€!) but totally forgot about the PSU.

 

Is the RM750x powerfull enough to handle this SLI-Config? I have another Corsair 750W PSU laying around, I could use that as second PSU. Wouldn't look that good but Ghetto-Mods are somehow always working. 

 

The Dual GTX580s wouldn't stay that long in the System anyway. The single GTX580 is so loud while gaming... Just need to save some money up

 

Would be glad to hear any similiar experiences or tips

Should be okay without OC. I've ran a gtx590 with a 750w, that should be similar. 

 

But really, you should get a new card quickly.

Bro get yourself a 1050 Ti or something! You can pick one up used for USD $80-100. Best wishes.

(If it was me I'd hold off on SLI as then you're prolonging any real good gaming experience by bogging yourself down with more burdens later to get rid of.)

(Plus SLI is hit or miss.) I know this wasn't the question necessarily but that's my $0.02

Cards draw a max of 244w each according to Nvidia specs.

@FloRolf Thanks! I am running the GTX580 stock. I don't plan to OC them. This bad boy gets way too hot (~90C while gaming). I cleaned it already and applied new thermal paste. I guess its just bad cooler design...

 

@camjay yeah I know, a friend recommended a 1050ti too but 20 bucks for an 580.. had to try that  

 

@schwellmo92 Guess it will work then 

 

The 580s are a big bottleneck, the will move soon. I think around christmas. I hope I get "okay" results @1440p for now. 

 

Anyways thanks to you all. I guess I have to try it out. I'll post the expierence and results. (GPU should arrive in two days)

Hey there,

 

I've installed the second GPU and tested it for a while. Doesn't look good...

The system kept crashing in Games and Furmark. Sometimes it just powered off and sometimes I got a Driver-Error-Message. 

 

Since I didn't spent so much on the second 580 I decided to keep it and just remove the old one. The Temps are a little bit better.

 

Good News: My work situation got stable again which means I'm able to get an RTX2070 in a few weeks. Planning on an Asus ROG-O8G

 

I'll post a few pics of the Build/Audio Setup when its done
