Re: Claymore's Dual Ethereum AMD+NVIDIA GPU Miner v9.2 (Windows/Linux)
Hi guys ! Correct me if Im wrong. If i see 1100 watt from the wall on my wattmeter , so on 80+ Standard PSU its 1100*0.8=880 power load of PSU. And its good enough for PSUs working conditions (1000Watt Chieftech)?
I mean its about 85% of its full load.
Right ?

Right ?
If you have a 1000W PSU how can you see 1100 at the wall? Something is wrong...
The 80+ standard is a measure of efficiency. No PSU will deliver 100% of its nominal output, 10~20% is lost in heat.
Therefore, a 1000W PSU will only deliver ~800W within a limited range of loads, and not at full load. Got it?
A 1000W PSU will never "suck" 1100w from the wall....
That is not correct.
See here:

"Load Regulation And Efficiency Measurements
The first set of tests reveals the stability of the voltage rails and the PSU's efficiency. The applied load equals (approximately) 10 to 110 percent of the maximum load the supply can handle, in increments of 10 percentage points...... 1500W PSU Output - 1549.07W, efficiecny -89.04%, PSU input 1739.84W ......"
Interesting article. Looks like 50% As well as 100% load are not efficient mode of operation. from 80 to 90 % is the best PSU load.
Cool... cuz my 3 1200W Plat PSU's are all at around 1000w... so right in that sweet-spot range
A bit off-topic but avoid MSI like the plague and make sure your RX cards have Samsung RAM only, exchage any Hynix RAM cards before its too late! I'm going on 3 weeks now waiting on MSI for RMA. 100% defect rate on 7 of their cards, even the one armor card had fan barrings go after a week.
I have had more than a dozen MSI gaming X 470+480. Not a single one failed, all except two were Hynix.
On the other hand, out of a similar number of Sapphire Nitros, one failed (ball bearings, screeching sound and on another one fan was making noises, but card was working, so i just had it replaced).
Yeah, I'm not sure what this supposed issue with Hynix RAM is on MSI 400 series. I really wonder if it's people trying to aritficially reduce the demand for the remaining few new ones still in the market so they can hoard them themselves. I personally have been running 21 MSI 470's for between 2-7 months... 17 of the 21 have Hynix and the other 4 have Samsung. To date, have not had 1 issue with any of these cards, including all 17 Hynix ones. In fact, 4 of these have probably been in use for more than a year as I bought them used from Philima1957. So again, not real sure what's driving a few people to bash Hynix but i have not experienced or heard reliable accounts of any real issues.
