2 PSUs?

[Beat_my_Laptop]

I've seen it in mining rigs & servers but not any sort of PC's, but since the Tesla k80 exists I want to know how I could run it (or any other insane card that chugs power) in an ultra budget build (how budget? I'm buying used parts, taking components out of other PCs, and would absolutely make a waterloop with vodka & aquarium peices if it saved money).

 

Can I use 2 power supplies?

would I have to do anything special to hook them up?

 

 

example, my minimalist build needs a 450w PSU, adding one Tesla would bump that to 750w, if I have an ATX Mobo I could run a second Tesla for a grand total of 1050w. If I had my way & paired it with a Threadripper Pro that's a 1200watt power supply- expensive & no used market. But 650watt power supplies are extremely plentiful (& about 60% off) on ebay.

76$ ea. For 2 650w

vs.

220$ for 1200w

Best do this on high end 1000w or 1200w psus

 

Its quite dangerous and might be a fire hazard if you do it wrong but as long as you have good psus and knowledge you should be fine

 

Then again youd need 1500w for a 4 tesla k80 config so go for atleast 850w psus

keep in mind each PSU has to be able to deliver what is required of it, not just the total power of the overall system, but the total power each PSU is required to draw. 

 

If a GPU is rated @ 300W, and the Threadripper is rated at 300W = so approx 600W load for 1 of the PSU's, then you'll probably want a reliable 750W PSU for that alone (assuming its not some garbage $40 "750w" from China that really delivers about 400w). 

 

Probably you'd want to run the entire system (CPU/Mobo/Memory/Storage) on a primary PSU, and then the cards on a second PSU. 

 

You can get 24 Pin splitters for triggering the 2nd ATX PSU, such as this one: https://www.amazon.com/Haokiang-Supply-24-Pin-Motherboard-Adapter/dp/B08T75WP14

 

In reality you could run a Threadripper Pro and 2 K80's off a Corsair HX1200, and its pretty cheap in comparison to the price of the CPU....who buys a $3500-5500 CPU and cant dedicate 10% of that cost to a PSU?
