Which PSUs have the 8-Pin PCI-E Connector?

yes i do understand that unline the hiper psus, when the review sites opened up the corsair they found good quality capacitors etc so the materials used are good, but its not just the parts that make up the psu that have to be good. the reviews did memtion corsair not screwing down the heatsinks properly etc, its odd though.

what i don;t get is how corsair can have a psu from seasonic and have it fitted with better grade capacitors and yet still undercut the seasonic equivalent psus in price? something has to give there, and i think we are now starting to see the trend, you don;t get seasonic quality for less than seasonic price.
 
I dont really want to spend that much on a psu though :( was happy about the cost of the 520w corsair. What do you think would be best to get from either enemax or seasonic?

They both are at least 70 qid for a 500w+ but the seasonic isnt modular. Do you reacon 500w is enough to run cards of the future as well? well if 500w will run a 2900XT i reacon it should. But do they both come with 6+8 or 6+ 2+6
 
Thank you for all the replies everyone and sorry for not replying sooner :)

My reason for asking was because im planning on getting a new pc. I knew that the corsair psu's had the 6+2 but thought they where expensive and wondered what other psu's had them. It was to be a bit more future proof in case all graphics cards start needed them.

If thats the price of them though :eek: but if its needed in the near future, im happy to get it now rather than get a cheap one now and need another too soon.

Thanks again for all the information everyone :)
 
Dont ever get a cheap psu. if taht psu goes it will take out all your pc. And youll need to claim on house insurance as they wont pay for that which they destroyed in your pc.

Corsair are a good reliable make. So are enemax and seasonic.
 
I think it's more a case of there's been a lot of first time pc builders failing lately most of the corsair bad press i have seen the people don't even know to plug the 12v connector in.

You do if you cut you profit margins to gain market share. You post proves it- brand name means you can have a higher price and get away with it.
 
The most over looked Power Supply brand on these forums are probably SilverStone units.

The Olympia and Decathlon 650/750w units are something special. You need to get a revision 2.5 though. Unfortunately Revision 1 and 2 have whine problems, which isn't a sign of poor quality - it's actually the contrary. The whine on Rev 1 and 2 comes from exceptionally fast transistor switching to give cleaner DC supply.

Rev 2.5 doesn't have the whine under load problem and has an 8 pin PCI-E cable. These PSU are single rail (much better than split, due to not having low OCP values) server quality power supplies which are OEM'd by Etasis. The Olympia is the non modular version, the decathlon is the modular.
 
just got a seasonic s12 500w and very impressed, quiet got the 8 pin connections on as ,well built not modular (not bothered really) but it has cable mesh on the cables to keep em tidy overall a very good psu.
 
Not that I'm aware of, modular means just that.....only use plugs that you need.

However my last two PSU's have been modular, they are so much nicer to deal with...
dont think I would go back to the old style.

Ive just bought a corsait HX620, not even powered it up yet but im not overly worried,
The corsair units are incredibly popular at the moment, the one or two failiures ive heard of really is a drop in the ocean, everyone and thier mother seems to be running them.
 
Its just put a worry in my mind for every psu realy. Any psu can be faulty. Just the thought of 1 grand of stuff dieing instantly to a psu and not getting a refund because it was the psu.

iv bought 2 corsairs now, a 520 and 620unit, although they are working for now but i am a bit worried about them. and the corsairs replaced 2 hipers, a 580w and a 480w hiper which were both running and the reason i changed to the corsair was for peace of mind hoping they would be more reliable.

:D:D Should've left the Hipers in.
 
Truth be told, I was looking at the antec 850, which was about £115 iirc
But considering the way graphics cards are going in terms of better efficiency ( I think the current hogs like the 8800GTX are pretty much as hungry as youll get ) I think the 620 will be fine.

Its got an "nvidia SLI ready" badge on the box, although officialy it dosent support 2x 8800GTX, I have seen reports that it can do...
"8800GTX SLI in the lab with 4gb of memory, a C2 Quad, OCed"

I only ever intend to run a single high-end GPU with a max of 3 HDD's, so im confident it will be fine.
I intend to use network storage if i need more space, its much more sensible than cramming 10 HDD into a single PC when you can have decentralised storage to share between devices.

Reading through the instructions, it has a wealth of various cicuit protection, so if it did fail, I cant really see how it would damage anything apart from itself.

However, on reading the small print in the instructions, it does state "not for use outdoors".....maybe thats the reason for the small number of failures:D

an easy point to overlook, i know;)

Get it is all i can say, I have the Antec 850 Quattro, if that is the PSU your talking about.

My 2900XT requires 750W PSU minimum see requirements here: site covered in competitor links i'm afraid.

Mine is powering:
GA-P35-DQ6
Q6600@ 3.4GHZ
Diamond 2900XT 1GB
4GB RAM
2x Raptors 36 & 74
1x WD 500GB
2x WD250GB
1x Maxtor 300GB
2xDVD-RW
Fan controller with all the fans from the Antec 900 and cathodes.

Without a glitch, and still runs very cool. Very reccommened PSU. My old Hiper 580W was just not upto the job anymore.

Oh and the PSU has 2x8PIN PCI-E and 2x6PIN PCI-E, along with a 6 pin mobo connection (12v?) with more than enough molex and SATA connections.

Hope this helps,
Matt.
 
Your 2900XT does not require 700w. They overcompensate totaly. On that website it states 750w. What a joke, more like an excuse to make more money off people.

You could run that on 500w so a quality 600w power suply would do it as no power supply runs at what it states. You can run a GTX with a overclock quad and hdds on 400w i beleive. So with all your added things and the fact the 2900xt used a bit more then the gtx id say 500/550w.
