Hi, i have a rx 580 Nitro+ 4Gb gpu, with a power supply of 650w
if I only use ethereum mode, all its fine (24mh/s) but, when I try dual mining, after a short time, my pc reboots, could it be caused by lack of current or voltage?
I run the miner only with required parameters, epool dpool wallets, and passwords, my rx 580 is NOT modded and running at 60-64ºC
Could anyone help me with that?
Also.. which pool is the best for 1 GPU?
Thanks
NOT ENOUGH POWER--
You need a 1000W PSU for 5 to 6 GPUS. A PSU needs to have more capacity than the maximum power draw for ALL of your GPUs combined. The highest efficiency is at about 60-70 percent of the rated capacity of the PSU.
You can not get by without overloading and burning out a low-power, low efficiency PSU. 5 x 150W equals 750W, and that is greater than 650W (your PSU). A low-wattage algorithm may work for a while, but the PSU will still burn out. It could also explode or catch fire.
I no longer buy cheap, unrated PSUs. Stick with Gold, or Platinum, from a reliable manufacturer with a soiid warranty. A PSU will really explode if over-worked. --scryptr
yeah, 1000w for 5 o 6 gpu, but I only have one, that should be enough...or not?
YOU SHOULD BE GOOD--
In your case, I would begin checking for another hardware problem. Overheating, or a poor connection somewhere. It still could be the PSU, if your PC has a bargain PSU. --scryptr
This is my psu (bougth 6 or 7 years ago with the cpu and motherboard (the newest component is the gpu) could you evaluate it please?
IT SEEMS GENERIC--
The specifications are not in English. Most USA PSU manufacturers use an efficiency rating scale involving colors: White, Bronze, Silver, Gold, Platinum, Titanium, with Titanium being tops. Not all manufacturers use all of the colors for their models. An "80+ Gold" PSU is considered good.
The PSU you linked for me did not have a rating. I have some older PSUs that really just have a wattage number tacked on, but can barely produce 1/2 the load that is claimed on the label.
The other thing is the warranty. The best warranty service in the USA, for my money,is EVGA . I just bought 2 EVGA 80+ Platinum PSUs that have 10-year warranties. EVGA backs up their warranty with service.
Your PSU is likely fine for 1 GPU, especially an RX 580. For some reason (it was very late when I answered your post), I thought you had a multi-card rig. If you do build a multi-card rig, don't try to save money with a cheap PSU. the better-rated PSU will use less electricity and last longer. That means the GPUs will pay for the PSU more quickly, even if it is an expensive model. --scryptr
I have search on internet... I got that my psu has an Efficiency of >=72% the lowest rating you are talking (bronce) has 81% so my psu has only 72% of 600, 432w...
Also, since i changed from gtx 960 to rx 580 Some videogames are forcing pc reboot, (only the new ones) for example FIFA 17 when selecting "no fps limit" instead of fixing it on 60fps)
I have used GPU-Z to check temp and speeds, when the card is at the maximum speed, and consuming 180w, it reboots the pc.
Analizing all of this.. I think that I need to change my PSU...
