This was an OCZ PSU :s though one of their better ones so I'm a little surprised - not like a channelwell based unit or something where it would be a bit less surprising.

have OCZ stopped doing PSU's? i had one in my last rig and it wasnt half bad

OCZ don't really exist like they used to they pretty much folded - Toshiba bought up a lot of rights to the name and some other company also has some licensing to the brand.

EDIT: Looks like they are pretty much completely defunct now - Toshiba phasing out the branding and no one else producing products under the brand.

Feel free to also take Kyle's word that you can use a 500W PSU (/snigger) to run Vega 64 over AMD's official word.. they stated 750W *minimum*.

You say you "know about PSUs"... Do you know that a 500W PSU at full load will pull more watts from your wall than a 1000W PSU at 1/2 load? You knew that, yeah?

Did you know that a 500W PSU at full load will run pretty damn hot, and possibly be dangerous if run like that for long periods? You knew that too, right?

So let's get all this together...

You're happy to take Kyle's word over AMD's.
Your happy to run a 500W PSU at full load for long periods, and would recommend this over running a 750/850/1000W CPU at ~50% load. Despite the fact that it will cost you more in electiricity to do that (negating the saving you made from buying a lower-rated PSU). And you're happy to reduce the operational life of your PSU in doing so (further negating that cost-saving you made).

Good stuff. Clearly you know what you're talking about :p

You are doing the usual, exaggerating everything to suit your argument and make things sound worse than they are.

Do you know why AMD recommend a minimum of 750W? It's for people who don't understand PSU's and automatically think that all PSU's are made the same and buy the cheapest one.

A guy , who reviews cards etc. for a living, has measured the RX Vega power consumption from the Wall and has said that in a system that's not overclocked a 500PSU is good enough. He suggests that you use a 750W if you plan to overclock.

But, you, who has no way of knowing, have claimed that he is wrong.

I am not making any recommendations either way, just pointing out that a super high wattage PSU won't be needed for RX Vega. You don't need one for Vega FE.

You are also a bit wrong about power supplies, Most people these days buy power supplies that have a minimum of 80+ bronze certification. What this means is that that efficiency curve is pretty linear once you get past 10% load. The difference between 50% load and 100% load is minimal. And, with good certification, power supplies will happily run at whatever load you like for their entire lifespan. Of course, and just like any other purchase, you should check reviews to see if the PSU runs as advertised.

And lastly, people who will spending $399+ on an Rx Vega card will more than likely have a good PSU already. So I don't know why it's been factored into the cost of getting a Vega card. People that are on 390/290/79xx cards looking for an upgrade path will definitely have a good PSU. People like to make mountains out of molehills.

Yes, I do know what I am talking about.

EDIT: I see CurlyRiff has went into more detail about PSUs. And I just want to add, I am talking about air cooled Vega. The Liquid version will need more power as it has an AIO cooler.
 
Have to say I'd be a bit wary running a 500 watt PSU with a reasonably high end CPU paired with a Vega GPU based on what we've seen so far - it would work but you ain't leaving much in the way of margins.

I never said I would. I would be a bit wary as well, I am little old school when it comes to PSUs. But it would probably work fine for years. Just did a basic Vega FE setup on one of those power calculators. 520W recommended for 24/7 gaming :)
 
I do think Vega 56 probably looks like the sweet spot of the range,if the TDP figures are anything to go by,and the price should technically make it around £100ish to £110ish more than what the RX480/RX580 cards were going for at launch.

Thats a shame, i still have an old OCZ SSD and its been faultless for the best part of 5yrs

56 will be no good for Fury owners though, if the 64 is only about 20% than it, be more like a sidegarde.

I wouldn't even bother going to a 64 from a Fury either tbh.

Same with AMD though, none of AMD card's give users the pro-software optimizations except the FirePro and the Vega FE, not not the Vega RX

Fair enough, but it's a bit of a coincidence they magic up the following on the back of an AMD launch. Why wasn't this performance there previously. 3x is a lot!

"delivers 3x more performance in applications like Maya to help you create and design faster than ever"
 
The power stuff isn't rocket science or new.

You dont want the peak power you can draw anywhere near the limit of your psu.

So if you get a liquid vega at 345w plus a cpu at... lets say a 7700k at 91w you're at 436 just with those.

Then add hard drives, ssds, optical drive, fans, motherboard itself

Oh and overclocking could add another 60w to that cpu.

Actual lies about TDP could add a bit more.

500W for all that is asking for a problem when something puts a heavy load on the main power hogs of the cpu and gpu. You just won't know until you try to draw the power since just booting up and mooching about on a browser is easily below 100W.

750W does actually sound alright to cover all the bases if you go for a 345w graphics card.
