According to some videos and articles that I read, that GPU can consume from 200 watts to more than 250 watts at full load. I don't think it is safe to use a 1000 Watt PSU for 5 GPUs especially if it doesn't have good efficiency. Maybe add another 1000 Watt or 1500 Watt PSU just to be safe.

Ohh ok..thanks for quick answer..i have few psu available right now..
Inter-Tech SAMA FTX-1200-1
KOLINK KL-C1500PL 1500W
Silverstone ST1300-TI..maybe some of these..or any other solution ?

There is no other solution than buying more powerful power supply, 1400 or 1500 watts will do just fine

Assuming you are mining ETH, 1000 watts will be enough to power 5 x 5700 XT plus MB, CPU, etc. but only if you undervolt the GPUs. If you wanted to add more GPUs in the future you can get a little device called add2psu to connect the 1000w and 850w PSUs together. One thing to keep in mind though is that If you are using risers you need to power the riser and GPU from the same PSU.

Exactly like that..i already start to mine ETH,with riser and 5x 5700xt 1000w and overclock undervolting ..i get so many issues..so i ask for help..best option and to resolve problem

What issues you having?

Rig working few hours,and then one of gpu lose mhs..example 55mhs to 0 mhs..and show like gpu is dead..!! I check risers one by one works well..stock gpu work some period and again on 0 mhs..undervoltage as well ..if i put 4 of them..then works without problem..

This happens when you either overclock or undervolt too much. Try dialing it back a bit on the GPU that is failing.

Yes correct, add some mv until it is stable

I try from 750 till 1200..step by step(750-760-770....1200)..all time same..

ok did you decrease oc? which miner are you using?

[KaBro]

Yes even that..from max to min..always same..i try phoenix n trm..

ok. is your bios modded?

[KaBro]

Yeah..even stock even flash..i think still its psu problem,not enough for 5x 5700xt

When psu not enough it usually turns off. Whats name and model of the psu?

[KaBro]

Silverstone st1000-pt..1000w just using to supply gpu n riser..

Psu looks ok. did you tried with 4 gpu?

[KaBro]

Yes and working well..no issues..
