Power Supply Unit for OC and SLI

[XiN]

Hi, I need a new PSU. I'll do OC and make a SLI system (2x6800GT).

I have seen this PSU: http://www.enermax.com.tw/products_page.php?Tid=1&gon=252&Gid=18&Gid2=25 @ about 140$

is it good? differences with Coolergiant serie? Is OCZ Powerstream 520W better?

Thx :)

PS: right section? :confused:

Here it is unavailable :(

I think OCZ 520W is good choice :D.

Regards :toast: .

I am using the OCZ 520 and I found it to be excellent. I have since built 4 more for people that also over clock and they seem happy with it also. The adjustable rails are a nice bonus with this PSU.

I'm not a big Enermax fan but it seems to be adequate if that's all you can find and the price point seems fine. 36amps on the 12v lines with all the connectors neccesary. It's not a bad looking unit either.

How about this (http://www.io-tech.fi/pic/uutiset/05_0220_power.jpg) custom made 1320 W powersupply? :D

lol, you have the same tester than me :p:

Ocz Ps600w Adj.........

Interesting.....
When using the OCZ 520w with an SLI setup, I've run out of 4-pin connectors :(
I have 4x connectors feeding the GPU's, one to CDR, one to HDD, one to Mobo (DFI), one to a fan, I was going to add another fan cooling the GPU's, but had no power lead :(

I think your thinking of the 700w zippy. Thats the best PSU :D , but it also is $300. :(

Thx, so I'll buy it ;)

I think I can't find better at that price (OCZ Powerstream costs about 200$) ... other models you have mentioned (Zippy, Pcp&c) in Italy are unavailable ... maybe in Germany, uhm :D

But Powerstream 520W runs with a SLI system even if it isn't "sli certified" ?

[_Veseliq_BG]

FSP - Fortron 550W is also a good choice ! It is a greate PSU I must say. Surely better then the Enermax.

Yeah the 520 definetly works with SLI setups

[[XC] moddolicous]

What about the PCP power cooling 510 SLI ready? You can order straight from their website to anywhere in the world.

[jjcom]

OCZ 600 or OCZ 520W PSU is what I would get. They're very nice PSU :D

pc p&c 510 sli here, great psu

[xtrempinoy]

i have a enermax 485w noisetaker, excellent powersupply, you should get it, its a very good powersupply

[J-Pak]

I like what the OCZ ceo said about their Powerstreams. Something along the lines of if people are comparing our PSU's to PC P&C then we know we are doing something right :)

[LightSpeed]

I think your thinking of the 700w zippy. Thats the best PSU :D , but it also is $300. :(

Nope, 600W

Zip (http://www.newegg.com/app/ViewProductDesc.asp?description=17-103-710&depa=0)

and its only $185~.

And i agree, the Fortron 550W would be better than the Enermax.

I didnt even notice that. Sorry about that.

[Arseface]

I'm thinking of getting a bigger PSU for my SLI setup, as my enermax noisetaker 470W is getting close to it's limit when everything is working flat out.

Would the PC P+C 510 be the best I can go for, or would I be better off with the OCZ powerstream 600W?

The PC P+C seems like it has 2 12v rails each at 30A+, which is incredible! But then again, it's only rated for 510W :confused: If that was the case, those two rails alone should be >700W...

[jjcom]

Either one. Which ever one is cheaper is my advice :)

Basically, its an opinion thing. Some will say OCZ, some will say PCP. Like jjcom said, whichever one is cheaper for you.

[Arseface]

Cheers guys :)

Been looking round, and I'm leaning towards the PC P+C 510. The only thing that concerns me is the fan volume. 34db seems a hell of a lot for a PSU - even if it is pumping out insane amounts of power.

I know that fan volume ratings are usually pretty much fantasy, and that PC P+C seem to actually use realistic ratings for their various specifications, so it might not be as bad as it sounds. Can anyone tell me quite how loud the PSU fan actually is? Would it add much noise over the vapochill XEII that I'm running?

thanks :)

[LikwidKool]

I can say do not get a OCZ 420 as mine just choked with SLI. Ran 2x6600gt's fine but not 2x6800gt's. The 600watt OCZ I got in works like a charm though on the 6800gt's oc'ed at 400/1100 for now with solid rails.

[LightSpeed]

I didnt even notice that. Sorry about that.

No prob,

Actually i also thought i was mistaken after your post, but then found out i was correct afterall, the 600W Zippy has better 12V rails than the 700W one. the 3v and 5v rails are much weaker tho.

why isnt anyone considering this PSU at all, and it seems to be a showdown between the 510PCP&C and 600W OCZ?

if this psu is too big to fit in the case, then the 500W Zippy would be good to. For cheap, i say go 550W fortron, surely.

[drunkenmaster]

46x12 + 30 x 5 + 30x3.3 = 801W , again, with all psu ratings they are MAX ratings on the lines when ALL other lines are at their absolute minimum loads. Its still a pretty good psu, though lots of people say its loud.


as for the ocz, charlie i ran outta connectors on the 600W on a sli setup, 4 hdd's, bunch of quiet fans. fan controller. the noise of psu as it seems under fairly high load, is pretty loud, might chuck the 520W back in as 2nd psu for some of the stuff to reduce load on psu, and so fan noise should drop a lot. lines weren't looking to strong on the 600W either.

[LightSpeed]

yep, its a bit loud, and yes Zippy, for me, conservatively rate their PSU's like Fortron.

u ran outta connectors? how many 4pin molexes are there?

[drunkenmaster]

no, i'm not saying they conservatively rate there psu's, pretty much no companies do that as simply put, why sell something for less than its worth. I'm pointing out that every single company quotes the max on one line with min load on other lines, you won't ever get full ampage on any lines under normal use.

as for the 600, theres a pci-e, a hdd shielded, 2 sata's and two rails of 3 or 4 molex's, can't remember which off top of head. heading back to uni this evening so will get a chance to try overclocking and dual psu set up tomorrow, as of the moment my dfi seems awful and won't overclock in the slighest.

[J-Mag]

Has anyone notcied any increase in overclockability of your SLI rigs / Adjustable 12v rail pushed up beyond 12.5 ?

I mean the 3.3v adjustable rail is good if you are doing a direct 3.3 to dimm mod, but does inceasing the 12v rail help you dual gt's or ultras clock higher?

Anyway, i have been thinking about switching PSU's, but so far the 400w Zippy I have powers my winnie @ 2.5ghz, the 6800gt's at 410 1100, and 6 SATA devices 2 Opticals( i am using 4 Y Molex splitters), 3 Fans without dropping below 11.95 under load... It is amazing that only "400w"... can keep all that crap running...

[Corsairs]

I was going to start a new thread, but since this one was up on the very topic I wanted to ask about I'll post here: how would the EG651P-VE (http://www.enermax.com.tw/products_page.php?Tid=1&gon=243&Gid=26&Gid2=38) 550W PSU work for an overclocked SLI rig? The price is reasonable and it seems to have a pretty solid +12v rail (36A). I'll be using it with a DFI NF4 Ultra-D (modded to SLI). Will it have all the connectors I need to get everything hooked up?

Also, do you generally prefer single or dual +12v rails, or does that even make much of a difference?

[LightSpeed]

no, i'm not saying they conservatively rate there psu's, pretty much no companies do that as simply put, why sell something for less than its worth. I'm pointing out that every single company quotes the max on one line with min load on other lines, you won't ever get full ampage on any lines under normal use.

by conservatively, i mean compared to other manufacturers.

Compare PCP&C and Fortron to many , many other manufacturers, their watt ratings and the actual output, then ull see.

The fortron 500W ATXV2.0 blue storm is a good example, a review about it actually ran it outta spec for quite some time, then found out the fact that they indeed werent running it within spec. It was perfectly ok.

[mr_knowitall15]

Zippy 600W with 46A on the +12V rail...
i was gonna say, the zippy has hella amps...

[Arseface]

Well, I just ordered the PC P+C 510 SLI. Should be here next week.

It doesn't have the rated current that some of the other PSUs do, but looking at the pics with the casing removed it seems extremely well constructed, and that's always a plus. Also, it seems from the reviews and specs like it holds it's output well under high temperatures, which is a plus.

Hopefully it should do the job, and also provide for an ungrade3 to a pair of 24pipe cards in the coming year :)

[LikwidKool]

the pcp&c 510 sli should do well. They are great PSU's. Until Zippy, and OCZ came along they were king. Also I doubt that they would release a PSU as SLI certified unless it could run 2x6800ultras.
