The power supply that I have is a Corsair HX1200i . It's rated Platinum. I was hoping to use the integrated Corsair link to diagnose these kind of problems but there are no drivers for linux.
Now, I am faced with two options:
1) buy an extra smaller power supply to complement the existing one, for example an HX850
2) leave it as a 10 GPU rig and start afresh with a new rig
Option 1 would be slightly more cost effective, but I never assembled a rig with two power supplies and I am concerned with possible power loops.
What do you think?
I have 6 rigs and all PSU are from Corsair;
TX850 (non-modular)
RM1000x (6 PCIE capable - comes with 4 * double headers)
HX1200 (6 PCIE capable - comes with 4 * double headers)
HX1200 (as above)
HX1000i (6 PCIE capable - comes with 4 * double headers)
AX1200i (
8 PCIE capable - comes with 2 * double headers and 4 * single headers)
We always need one PCIE for the CPU, so here is the max card set-up for each PSU (single header / double header);
RM1000x / 10 / 5
HX1200 / 10 / 5
HX1000i / 10 / 5
AX1200i / 14 / 7
The AX1200i could technically do 14 cards if single 8 pin - but you would have to buy an additional 5 * PCIE double headers (they go for about $15 ea.). You also would break the golden rule that says 2 risers per peripheral power string. All of these PSU's are capable of 6 peripheral strings max, which is 12 cards if two cards per string. You would have to buy more of those too, or mishmash your riser set-up (3 molex, 2 sata, etc)
I have bought a fair few additional cables for the above. Just be aware of the compatibility differences when ordering single cables on eBay, etc. Additionally, you can buy full cable replacement kits to get the extra PCIE cables, I recently did this at a cost of $100 just to get 4 more PCIE double headers as my regular eBay guy was sold out in December.
HXi and AXi cables are compatible with each other (Type 3)
HX and RMx/RMi cables are compatible with each other (Type 4)
Here is what I mine with each PSU:
TX850
- 1080ti
/ 1080 (blower)
/ 1070ti (mini)
RM1000x
- 4*Vega56
HX1200
- 4*Vega64
HX1200
- 4*1080ti
/ 1070ti
AX1200i
- 3*1080
/ 2*1070ti
/ 1070
/ 1080ti
HX1000i
- 3*1080
/ 1080ti
If I had my time again, I would buy only AX1200i / AX1500i. They have great adaptability with the two extra PCIE slots and have uniform compatibility with each other. The exception being HX1000i for Vega rigs (4-6). Stick with the cable compatibility type so you don't have to stock both lines and check when using.... ><
