PSU Just Exploded... What Should i Get?

I think the truth lay between your results and mine, LOL! The GPU value you listed here doesnt seem right at all... and Furmark is entirely an unrealistic load as Wiz anyway, so its absolute worst case above and beyond folding.

[n-ster]

Also, drdeathx basically confirms that the max per GPU is 300W+ as 775 vs 1100W between 2 and 3 cards

and @Crap Daddy

Who wants to have a 750W at around 100% all the time?

Also, @EarthDog, that sound about right. I have said the same I agree Furmark is more than what you can actually do. but to me 750W is too close for comfort, you want 850W if you don't want to add anything or 1.2K if you actually want to add another high-end card

Its not only realistic but its damaging. Damn benchmark should be banned.

Of course not, I was just saying that it should not have exploded.

Oh, that's just because his PSU was Crap (hehe pun not intended)

Perhaps I am missing something, but again, these cards can only go 20% over their power limit with the power slider. How can that be 300W+? TDP is 210 or 215W IIRC... thats like 250/260W, no?

Agree. There was a reason that Nvidia (fermi) throttled on that benchmark...err stress test.

[n-ster]

maybe it's disabled?

[EarthDog]

ONly on the Asus cards and Lightning can that happen though.. He has Sapphire? I dont recall that being able to happen on those cards, but never had a Toxic or anything...

His PSU is gold vs platinum, he has an extra pump, we have different mobo and ram (mine was tested at 2666Mhz but ram is negligible in it all)... and perhaps his KaW is on the fritz (or mine is!!! haha!). The first 3 can explaine the 40W difference in our peak results. But what I was calling shens on was the 800 number he mentioned initially.

EDIT: We also dont know what speed his CPU was at when he mentions that number... I know he did some sub zero testing, but not sure if that is where he captured that larger value.

EDIT2: 4.8Ghz... disregard.

EDIT3:

Pushing a PSU over 90% will end up with the same result he has now. Nough said.

I take exception to this as well.. I asked JG's own Oklahoma Wolf if he expects a quality PSU to run at 100% load for the its warratied life and he said yes. Shit PSU's like he has, I wouldnt expect it to either. But a quality PSU damn well better (not that I would run it up there myself, but it SHOULD work with QUALITY PSU's).

You do not need to calculate. I did it live.

No he is estimating, the truth is between yours and mine. LOL

please dont triple post. If you need help with the edit function PM me and we can sort it out.

What happened to the automerge doublepost feature this place used to have?

[sneekypeet]

no idea

I never knew we had one.

[T4C Fantasy]

well its pretty safe to say im going to sleep at a normal hour tonight... lol

[cdawall]

I would grab one of the superflower platinum based units. For the price they are the best bang for the bunch u it's out there. Rosewell has quite a few lines that are superflower based and none of them seem to have issues even with a 110% overload in a 45+ degree c case.

Both ATi/AMD and nVidia limit FurMark's GPU utilization. It can be circumvented, sure, but then that's the card's owner's choice. You can ban guns, drugs or giving whiskey to dogs - if a person really wants to do it, they'll find a way.

Solytech is actually capable of producing a decent unit, when motivated (pressed hard) enough. PowerColor's PSUs are all built by Solytech, and they're OK(ish). Extreme 850W, Extreme 1000W, Gaming 600W

The above is not a recommendation, I already gave one, it's just further proof that one needs to be informed about an individual product, rather than rely on brand reputation or product line reputation.

Well, except when it comes to high-end Seasonics, Deltas and Flextronics.

[camoxiong]

Get either a Corsair or Seasonic

[drdeathx]

As mentioned earlier, Corsair AX-1000 is $199. Problem solved for 2 cards.

[Aquinus]

There is a bit of a price premium on the Seasonic Platinum 1000w but it has worked pretty well for me so far. Fan barely kicks on drawing ~550-watts from the wall with a nice full overclock not to mention that a 7 year warranty is pretty awesome.

should run the the nearest best buy or PC retailer and buy a decent PSU to test your equipment with then once your done take it back.

Agreed 110% here!!! Even at the current $150 it is a great buy. I have two of these currently. One of them is in a AMD 4x4 (4 quad core) server system running the 4 cooling fans, 3 hard drives, two 240mm fans, and a 8800GTX!! It has been in the system for about a year and has never farted once!!

I have my figures crossed that it didn't take anything else with it man.

rofl that would be hilarious buy a psu just to use it to see if my superior hardware is still working then return the peice of shit because its not worth keeping, then bestbuy has to sell as an open box item 10% off haha

That actually a killer idea. That would at least tell you if anything else is wrong before spending a bunch on a quality unit.

[newtekie1]

Seriously, the OP doesn't need a 1000w PSU. The HX850 in my main rig handled two GTX470s, and the HX850 in Rig4 has handled a GTX470 and GTX465 and now two GTX470s folding 24/7. You don't need anything more than a quality 850w unless you are planning 3 or 4 graphics cards at the same time. Otherwise, with just two cards an HX850 will be fine.

Best Buy carries halfway decent PSUs, mine even stocks some Corsairs. They just overcharge for them.

And they really don't even overcharge that much for them, they are only $10-15 more than newegg, sometimes the same price but newegg has a $10 MIR or something to make the price cheaper.

I said peak. Do you comprend? it is not like you own 2 or 3 7970's and can give exact info.

I said folding for the reason of getting a 8970 and keeping the 7970 (you said why 8970, you cant crossfire) well the answer is prob that hell keep it to fold

the reviews for the gpu aren't estimates, the only estimating I've done is on the cpu and the rest of the system is not gunna be the same for you and him anyhow. On top of that my numbers aren't far from EarthDogs numbers. Do not forget I was looking at maximum consumption not real world

OP wants headroom for a third card so while 850 is perfect for now, 1Kw is bare minimum if he wants a 3rd card, I'd suggest a 1.2kw even
