Yeah, I'm beginning to seriously question the need for such high-end PSUs.

For two mine sites and I was given the task to purchase on behalf of the company all the hardware to make this happen.

Needless to say these PCs shall be working for at least 4 years before the next upgrade. Everything of course is tax deductible for the Company hence we never go short of the mark when it comes to providing the very best for our miners.

Think we are one of four companies throughout this Convict Settlement, that have catered to the hardcore gamers which are quite a few amongst certain age groups.

Wow. Then it's a privilege and an honor to help out! I had no idea. I kinda thought it was just a personal purchase as usual on here. This is pretty special and you honor us by asking for our help.

Known as Australia.

There is a push amongst the 'Higher Ups' to instigate a worthwhile pursuit on our mine sites besides drinking heavily down at the onsite pub. Quite a few of them arrive inebriated and some have lost their jobs because of it, so the Company thought to develop a Gaming Room for them to get involved with, instead of spending their available time down at the drinking hole.

It's free whilst the pub isn't, also after spending some time playing their games leaves them to sleep solid between the 12 hour shifts.

Ah yes.

I saw some reviewers managing to pull with the R9 380X 370W from the wall using platinium/titanium PSUs...

Also while researching on some issue, I found tutorials in Ethereum mnining blogs, about how to downclock the 380X to hit optimal power usage on the PSU.

Nevermind more powerful cards...

I saw some benchmarks ofr hte 295x2 using 980W from the wall. So I guess awesome PSUs really are a necessity today.

This doesn't surprise me though, one of the reasons CPU and GPU development is slowing down, is that we hit a power density problem, early on, people found out that as you made transistors smaller, they needed much less power and could switch faster, when dual-core CPUs became a thing, it was because manufacturers noticed that now each iteration in making transistors smaller was increasing the transistor count and frequency faster than it was reducing power usage, meaning every generation need more power if you keep increasing processing capacity, also every generation, even if you DON'T increase processing capacity, has more power in a smaller area (ie: suppose you go from a "40" to a "20" sized transistor, if you don't increase the transistor count, only make a smaller chip, you will get half of the chip area, but about 2/3 of the power, thus increasing the power per area, thus making cooling harder).

Altough everyone now is focusing desperately on reducing power usage because of mobile, noone is stupid to get "stuck" without performance, thus until the performance race stops, we will keep seeing ever-increasing power usage (unless someone figures out a completely new way to compute things, that use less power per unit of computation).

A 380X pulling 370W? Pretty sure thats full system wattage, but feel free to prove me wrong.

And the 295 is just a dual gpu card with 2 290X's which are notoriously power hungry. And I bet thats full system wattage too.

And you have to take power supply effiency into account.

These both are older cards too, not sure why you'd brig them up now.

As I said, 370W FROM THE WALL

of course it is full system wattage, I never saw "per-part" measurement of power from the wall.

And the 380X is not old, it is the most recent consumer (not "Pro") AMD GPU (at least until the 480 actually launches). And I mentioned it, because I bought one recently.

And I did took power efficiency in account, I said reviewer machines with GOOD PSU, saw 370W watts from the wall, meaning a budget (ie: bronze/white and non-80 cert) PSU probably would draw something like 400 to 500W from the wall.

The 380X in particular is a sort of "mainstream" card, thus if you have a higher end card, you can imagine a 500 or 600W PSU might be risky (ie: it will still work, but close to the PSU limits).

Or if you have multiple 380X for some reason.

Or if you use all the computing power of your machine (doing scientific computation, simulations, CAD, mining, etc...).

Also, if you look in the 80-plus rules, and ATX specs, they expect the PSU to behave at its best on 50% (ie: on 80-plus the 50% need to be more efficient than all other load levels for example), so maybe a good way to decide on a PSU might be calculate your average power usage on your most important loads, and then use that as "50%" level (thus if you calculate that in your most important tasks you will use 400W, it might be good idea to buy a 800W PSU).

Of course, all of that I am just conjecturing, so feel free to ignore me, I am just explaining why maybe people like high-end PSU.

A lot of those tests include 1200W bronze rated PSUs that are around 82% efficient. I've seen them. They add in something like a 4.6GHz 5960X and turn off all power saving features so the chip is constantly at full voltage. So no, those tests are horrible. For professional reviews, I would expect them to measure the GPU by itself on it's own unit on something like an 88% efficient unit. It's not that hard to do... I picked up my (discontinued) Capstone for $55 and it hits 88%-90%

There is a general rule of thumb: any CPU and any single engine GPU can run on a quality 450W unit. There are a few exceptions, but in most cases it is true.

EDIT: The 50% myth is a myth. Efficiency does seem to be best at around 50%-60%, but it's only a variable of around 3% efficiency on units worth buying.
