2080ti + 770 - Power question

[khalidsaboor]

Hi guys, need a bit of help here. 

 

I just got a zotac 2080ti amp. My old card is a gigabyte gtx 770 windforce 2gig. Now I have them both running so I can put them on FAH. Rest of my specs : 

 

Gigabyte x99 UD4

Gskill ripjaws 4 2133 4x4GB (xmp enabled) 

Core i7 5820k @ 4.3 

The gpus are at stock 

2x 7200 rpm Seagate 2tb drives in raid0

2x Kingston hyperx savage 256gb ssds in raid0

1x HP EX950 1TB Boot drive 

4x stock fans that came with my nzxt h440 

1x wifi card

1x led strip (double, with 5 leds on each) 

Corsiar RM750 

6x USB 3.0 peripherals (including 1x 2tb WD my passport drive) 

 

So my question is, will that PSU be able to handle it? I have disabled FAH on my cpu since I'm afraid something will crash and burn. 

 

Both Gpus are at around 30 - 50% usage and ~ 75C while folding. 

 

Thanks 

 

PS. I can't get a watt meter right now because my country has a super strict lock down in place. Also, I have a good quality extension board, connected to a voltage stabilizer.

TLDR

 

But, 750W is more than enough, a 550W PSU would be fine.

 

For reference my R7 3800X + 1080Ti + tons of SSD's+HDD's has never pulled more than 450W Max form the wall.

 

Also, PSU calculators always overestimate (if you checked any) as they get numbers from adding the max power draw of each competent, which in the real world NEVER happens. 

 

And the RM is a solid PSU so no concerns here.

The power supply can easily handle it but the 770 isn't really doing anything useful, rather, it's causing performance drops

Thanks a bunch, that answers it all. 

Time to fold 24/7. 

 

Have a good one, buddy. 

 

Also, stay home, stay safe!

So I'd be better off just removing it? It can't do anything useful at all? How about using it as a dedicated physx card? 

 

Excuse the noobness, please.

LMG have a video on that. A physx card which is so much slower only slows down the main card since it has to work at the same pace as the slowest card

Understood, so I'm better off just removing it and using it in another pc. Thanks a bunch for your assistance. 

 

Stay home, stay safe!
