Is it safe to use regular, not server psu with asics? How to start it, just use simple jumper?

The reason you use a server PSU is because they're designed to be running all the time. There are many reports of 24x7 operation under max loads killing ATX power supplies.

Yes you can run asics with an ATX psu. Things to make sure you know first though:-

1) buy one that is almost twice the power you need (e.g. If your asic is 800w try and get a 1300-1600w) as the peak efficiency is at 50-60% load. If not then allow at least 200w more than you need.

2) make sure it has enough cables for each connection as using the splitters or daisychains is almost guranteed to melt something or cause a fire

3) if its multiple rails then follow the asic instructions for the plugging order

4) you cold use two psus to power one asic but again make sure you follow the plugging order the same way you would do for multiple rails

5) switching on would be done with a jumper (paperclip usually, evga psus come with a jumper already made for you).

Also remember not to buy cheapo, noname PSUs. They'll cost you more in the long run with worse efficiency and possibly frying your miner. Reviews are a good place to start, and some good brands include EVGA and Corsair.

Agreed....Newegg has a good review history on most everything.....been very helpful in deciding what is good & what is crap for me  ;)

Whether I buy from them or not..............

Hi,

found two PSU's not being used in the garage (evga 1000 and 850 , gold 80+ model both).

if I want to power a 750W ASIC miner should I use one PSU for 2 hash boards and the other one (smaller) for the last hash board and the mainboard?

also, since they are modular, can any leads be used to power the gear? ie. the GPU/CPU/peripherals?

thanks

I actually only ran regular PSU with Asics because I couldn't stand the noise of the server PSU. Keep in mind this was back in 2015-2016 when it was still possible to keep an ASIC "not loud" unlike today's vacuum cleaner type of ASICs.

Never had any issues either with burning them out, I ran max 80% of the rated load however, never maxed it out. Some people had fancy ATX switch adapter to get it to turn on but I just used a paper clip between the 2 pins and never had any issues.

The 1000w will do the job fine. You'll probably find that the pcie cables are the ones that fit - 6-pin most likely. Just need to jump the motherboard plug or use the EVGA tester that comes with most psus.

I would go with the 1000 watt psu. It should do the job.
