I don't get why the PSU is $99.99 "Before $20 rebate". Wouldn't a company like Newegg WANT to advertise the rebate and say $79.99 "AFTER $20 rebate" ?

Don't ask us, ask them. ;)

I plan to use it for my computer with 2x 6800 gt and probably 3700 San Diego with 1gb of pc 4000 ram and I'll probably overclock everything to the max too... I can't decide which one is better cause I don't know much about PSUs any help is greatly appreciated.

Those almost identical, Forton and Sparkle are basically the same company. Either one will work great.

LOL. Fortron and Sparkle are actually the same company. I'd go with the dual rail FSP though. Split rails are usually more stable for OC'ing.

Edit: D'oh, Operandi snuck in while I was writing this.

Ditto. I just ordered it from Newegg, can't wait.

@OP - That Fortron is meant for servers, not desktops.

What?s good for a server is good for a desktop, I would go with the Forton.

Nothing, absolutely nothing will beat that Sparkle at that price point. It is up there with the PC P&C 510. However you must know that the server-class fan that it comes with is a bit loud. You would probably want to replace it with something else.

Also don't get the Antec TPII. If your case poses any backpressure to the fan it won't draw any air. This is due to the fact that the fan choice for it is very poor and there is a 1/8" gap between the lid and mounting surface. I also h9ighly doubt the PSU would be able to supply its rated amperage judging from tests I have seen that actually put a lot of load on the PSU. They are far better options in that price range.

I have tried a Truecontrol 2.0 sli certified for my setup, I bought one from frys electronics locally.... after 2 days of usage the fan went dead and I kept on getting lock ups I think one of the 12v rail is dead or the fan stopped working have destroyed the PSU, so I am not getting Antec again.... But serisously which one is better choice?... I'm having problems decide...

Ya, the TPII lacks functional ventilation. As for which one is better, the FSP550-60PLG is a much more capable PSU with its really beefy single rail, but you really do not need something like that and the fan is pretty loud. Nothing would stop you from replacing it though.

Are you limiting yourself to those two choices? I would recommend something like the Seasonic S12-600.

I just realized you were planning on running 2x 6800GT. Don't even waste your money. Just get a single 7800GT/X. It would perform better and be cheaper. It would also consume a lot less power. Then get yourself a Fortron AX500-A. It is cheap at actbuy.

SLI is just a complete waste of money. The only time you should even consider it is if you re planning to run two 7800GT/X's. Otherwise you would be better off buying a single card. Just the card alone would be cheaper. Also you wouldn't need such a beefy PSU and you could save money by buying a non-SLI motherboard.

Then he changed his mind since you said you didn't want the Antec...

Kensai replied before me :(

I would skip the 6800 GTs and get a pair of 7800 GTs. You'd spend a little over $200 more on them, but it would be a significantly better investment than two 6800GTs, IMO.

Or get one 7800GTX now and another one later. :)

:roll:

in case anyone actually takes this statement seriously it should be noted that one person i know of has had this issue and its not the person making the statement as he in fact has no experience with it.

as to people who actually own it, like myself, it indeed has "functional ventilation". 3 psu's in four different cases and not a hint of such an issue.

Maybe you should read my posts? I said if your cases poses any backpressure to the PSU's fan it won't draw any air. This is a fact and you cannot argue with facts.

no, the fact is one person you know of had an issue with his case and the tpII and because larva is someone who you are very impressed by, you cling to this as "fact" and continually make the same ridiculous assertion in every thread where the antec is mentioned.

the fact i can't argue is i have 3 tpII's and have run them in a CM praetorian. a silverstone LC13 (htpc case), an antec 3700 and a 2 skyhawk cheapos and i have never seen the fans spin above 1100rpm and typically they are ~900.

among other things, larva says "if the case is free flowing, you won't have a problem". well, the lc13 and the skyhawks are anything but free flowing. stifling would be a better description. you can take a look at them and see for yourself. the antec has been run with and without the front 120mm fan. no configuration of fans in any of these cases has given the tpII any problem at all. zero.

larva linked me to the case he has and i'm stunned it would have a problem with any air flow really. so perhaps he got a unit with a bad sensor? he never mentions how high the temps were when the fan spun up to 1800rpm.

it just seems to me that you are trying to sound well informed by parroting the info one person gave you despite the fact that many, many people are using these psus without this issue that larva experienced. why can't you just say "i'd rather have the fortron"?

btw, i read your posts and i don't see how i misquoted you. i've seen you state that the antec tpII's fan "lacks functionality" in a few threads, here and at xs and i think its irresponsible for you to continue making this assertion until you have more "facts".
