The 8 core showdown and analysis thread.

the 7990 is a DUAL GPU card. what are you doing trying to use to argue a point against me when ive kept saying single gpu, single gpu.

The thread was going on long before your single GPU mission which I am not debating. Like I said I went from a 7990 to a 290X which is dual on one board to a single. Keep arguing over the single gpu, single gpu this thread has forked around the time you started posting. :confused:

As far as the '8 year plan' goes, do you think gpus are going to get any more power hungry then they already are between now and then? I mean, in the last 10 years ive not had a rig that pulls >500w

Not really, I could get away with a quality 500w like you mention (7990 RMA's) but seeing as they are similar in price to a larger rated one then unless your into SFF or power efficiency (*cough overclocking forum) then your continuing this on for the sake of it.

My 650w Corsair couldnt hack mining with the 7990 with additional CPU draw. Luckily it came with a 750w for that very reason.

Let's rewind back to the OP:

Here are the specs to concentrate on. The AMD rig is as follows.

AMD FX 8320 @ 4.9ghz
Asus Crosshair V Formula Z
8GB Mushkin Blackline running at 1533mhz (offsets with the FSB)
Corsair RM 750 PSU
Corsair H100
AMD Radeon 7990 ghz
OCZ Revodrive 120gb running RAID 0
Windows 8 Professional X64 (note, not 8.1 !)

Then onto the Intel rig. Note, this was a rebuild, so components stayed identical barring the board and CPU.

Intel Xeon V2 Ivybridge. 8 core, 16 thread, 2ghz
Gigabyte X79-UD3 motherboard.
8GB Mushkin Blackline running at 1600mhz XMP
Corsair RM 750 PSU
Corsair H100
AMD Radeon 7990 ghz
OCZ Revodrive 120gb running RAID 0
Windows 8 Professional X64 (note, not 8.1 !)

!!! For somebody not debating the point, you dont half go on about it. As if i need to remind you, it was Mal telling snyper that a 550w psu was too small for the gtx760 he spec'd. Of course it isnt and that's why i said it was big enough for any single gpu and yet still Mal is going on telling us you cant run a r290/x on anything less than 700w, Codswallop, even after me posting one example (there are many) of some proper bench-tests. Meanwhile you keep trying to drop the 7990 in to the discussion when i said clearly from that start that i wasn't talking about dual gpu cards or sli/x-fire. Yes i get the OP is using a 7990 but neither svyper1 nor Mal were talking about one. Remember, i responded directly to Mal's comments on svyper1's post. Not the OP, not the OPs gear, nothing to do with any 7990. So no, it's not me on any mission here. Claim I'm defending Svyper1, that I'm part of some posse if you wish, makes little difference, other than discrediting your argument further.

Everybody else understands it perfectly. Say what you like in repose to this post as well, i wont continue derailing the thread any more. if you want to carry on by all means start another thread and I'll discuss until the cows come home.

Ugh, don't drag me into this FFS.

I run about 8 hard drives, numerous accessories (video screens in the front of the rig) and god knows what else. I didn't choose the RM, some one gave it to me when I was severely down on my luck.

I always use power supplies that are massive overkill FWIW. Skimping just means your PSU runs hotter, and, wastes power in the heat dissipation. Sure they're better and more efficient than ever but I'd rather not chance it.

That's a nice summary

The 7990 isn't a single gpu. Not in anyway except slotting into one pci E socket

I'd agree that 500w is ok for any reasonable single gpu gaming rig
But not anything intensive
 
what were we saying yesterday at psus !!!!!

ive just tried my rebuilt i5 rig and the brand new 750W Corsair blew straight away, without even a GPU in it............it cost £ 25 to send it back to Overclockers. ..... 25 flipping quid :mad::mad:

the guy in the shop said ``we've had a few of these PSUs blowing recently, Corsair aren't as good as they used to be``

this Corsair looks rubbish too.... i will spend a bit more cash and get another 1000w, Be -Quiet, because i cant see a replacement Corsair handling a 7990 :mad:

i expect the Corsair is made in China.... cheap Chinese junk....i'm really fed up today !!!!!!!!!!!

Seasonic based has always worked for me currently x650 gold.
FX8350 8 workers at 4.7 prime (270w)+ Heaven bench HD7870 concurrent = 390w measured at wall.

I can't believe the guy in the shop said that to you.

Corsair have a great reputation for their power supplies.
 
well Mal did say it popped without the gpu in there, so he's not exactly blaming the load on the psu.

Dont know about what the guy said the Mal, but to be fair corsair don't have the best reputation anymore. their cx, rx and ax series are known to be flaky.
 
I would agree with james about corsair not being consistent, I also had an XFX fail on me this year which was apparently seasonic. On RMA I got the Seasonic G as I think the fully modular ones are not as solid. My old 650w corsair from 2009 is still going though so I still trust the brand to some extent.
 
the corsair that blew was a budget CS750M, it blew the very first time i switched it on, the 7990 is nowhere near my rig, that cant be fitted until next week !.... my rig still needs loads of work, this is no longer my old rig, it's totally brand new.... only the i5 2500 and the RAM sticks remain from 3 years ago :)

i'm now using a Be-Quiet 1000w, it's miles better than that Corsair, it's build quality is excellent, big and heavy, dead silent, slow and lazy.

the corsair is more like my old OCZ, cheap and tinny looking and it also has very cheap packaging............but its cables are very good, unfortunately, the cables with the Be-Quiet are very heavy, hard to bend around tight corners and a bit garish, some of them have bright blue plugs :eek: i've no idea why Be -Quiet have sodded up their cables... a bit careless i suppose, i expect they'll get this right next time

but this is a trade off that i'm willing to take, for what is otherwise the best PSU i've ever seen, it's the same quality as their CPU Coolers.

mate had two gold ones go in a year. said he wont ever buy a corsair again.
 
If there is a better price psu for the wattage then I wouldnt buy it. But 2 CX500w had been bought (elsewhere...) for 2 PC's i built only a couple of months ago and they seem totally fine...i5 spec

still have my 5 year old CX600 ;)
 
i'd buy a top quality Corsair, it's the budget ones that i'd ignore

most PSUs come in a cloth bag, cables wrapped up in as separate bag/ compartment area, looking really neat....but the corsair was just bare, no protection at all, just lieing on top of the cables
