I might just zip tie it. I'm running the HP 1200w on 120v and it powers 4 of my 6 GPUs, it gets warm to the touch. I think if I ran it on 240 it would run cooler, I'm looking into that as a project for this summer.

Those parallel miner rigs are super clean.

Thats exactly why ive built two similar. I use a decent heatsink and some thermal pads zip tied to the psu to help with the heat and stop the fan spinning up too often.

Do you need 240V outlet for server power supplies to have maximum output?

No, 240V is slightly more efficient (maybe 1-2%). You can also get about 2x the rigs on a 240V circuit because the amps are cut in half.

HOWEVER - Just because the amps are cut in half, the watt remain the same. Your bill will not be cut in half.

depends on the power supply actually.

the HP 1200w only gives you 1200w if youre on 240v. on 120v its only 900w.

read the spec sheets

Checkout parallel miners (google their website) and look at there 6.1 gpu frame. Ive built one very similar as it has a decent mounting for server psu and atx at the same time (if needed). A zip/cable tie is always worthwhile for a bit of security too Wink

I used zip to fix my server power supplies. They are noisy if you put high load on them. Mine is 1200w, but I consume 750-800w from it, makes no noise as it doesn`t produce a lot of heat under low load.

Anyone got some good pictures of how to physically mount a server PSU to an open air GPU rig? I'm running a standard 550W ATX PSU and an HP 1200W Server PSU with a breakout board for an 8 GPU open air rig. The ATX PSU is very simple to mount, just drill a hole in the angled iron and put 1 screw through, no problem, but my server PSU is just sitting on the bottom of my rig, not secured down. Obviously I don't move it around very often, if ever, but I'd still like to have it secured somehow.

I used angle aluminum for the frame, with some wooden 1x3 boards across the bottom to mount the motherboard on.

Just looking for ideas of how other people mounted the server PSU. I was expecting it to be bigger, so I've actually got a lot of room to mount it in. It's also a lot louder than I was expecting, that little 20mm fan or whatever tiny size it is, is louder than all my GPUs put together.
