OCZ powerstream 600 or FSP Group (Fortron Source) FX700-GLN? hearing good things about both i need it to be stable as hell and help OC like a champ...
 
I see you're in the high range market, about 200 bucks. Why not head on over to PCP&C and pick up a nice turbocool 510? It's about the same price, and pretty much some of the best psu's ever.
 
because it is a nosiy beast my friend has one and although it is beast, i am walkign away from the 747 sounding PC. I do not want to mod it and change the fans... i just want a stock PSU with kickass performance and little to no tweakign neccasary. From everything i am seeing dual rail PSU's seem to have a bit of trouble with the DFI boards. so at that point i am seeing that either single rail or quad rail PSU's are the way to go. I also wouldn't mind the PSU being a little future proof. Johnny what would be your pick be?

OCZ powerstream 520watt ($140 Newegg)

or

FSP Group (Fortron Source) FX700-GLN (quad rail 700watt) ($170 newegg)
 
i am looking more towards a quiet PSU.. so i would say leaning towards singlwe 120mm fan solutions..

Two 80mm fans in a push-pull configuration will be better at removing heat than a single 120mm fan. The OCZ Powerstream is pretty quiet, I've got the 420W model.
 
yeah i just read some reviews on the strider, seams to be a kickass performer and it's modular to boot. i feel like an anuerism is coming on..... for future proofing, the FSp seams like the way to go (already 7900 gtx sli certified). on the other hand tech may change by the time i am ready to upgrade again... meh, decisions suck FTL.
 
SLI-certified is marketing for the most part. They pay nVidia to get a little SLI-certification sticker to put on their power supplies.
 
i am really diggin the silverstone Strider atm.. this is a nobo question but, efficiency is basicly how well the PSU uses the power it gets from the outlet to how well it feeds the pc components without wasting a lot of the power in the process? Now if that holds true then a higher efficiency would therefore relate to a less costly solution, for example if i use a PS with an 85% efficiency against say a PSU with a 70% efficiency then in the end the 70% efficiency PSU will cost me more in electric bills then the 85% efficiency?
 
You're correct, but the cost savings is sorta-negligible. A higher-efficiency PSU produces less heat, which is more important.

damn hard choices lol

heres ther thing the FSP has over 85% effieciency

http://www.xbitlabs.com/articles/other/display/psu-roundup_5.html

the Strider sits around 70%-75%

http://www.jonnyguru.com/PSU/ST60F/

Are the differences negligable or do they play a big role?

The differences are negligible, but I have to wonder how X-bit came to the conclusion of the efficiency. I don't question their testing methodology. It's one of the best. But he doesn't use conventional load testing equipment so I don't know how accurate his DC output readings are. If you measure your wattage based on how much amperage you put on the 12V rail and then multiply by 12V instead of what the actual output of that rail is (say it's actually 11.7 instead of 12V,) then your DC output estimate can be off.

Incorrect. nVidia is not paid for SLI certification of power supplies. Only certification of RAM (and honestly.. what would make RAM SLI compatible???)

Although I have to admit that SLI certification is rather lacking. Virtually anything with a certain amount of power on the 12's can pass.

ATI Crossfire certification is the real deal. They use an actual, built up machine and measure the actual load on the 12V rails as they run a gauntlet of stress tests on the PC. I've heard of some VERY GOOD power supplies failing Crossfire certification when they did pass SLI certification.
 
Would you hate me if I told you "either one" ??? :D

You're not running SLI, so they're both overkill. But if you were to run SLI, how would the FSP do? We already know that the Silverstone will work if you put the second video card on 12V4 by using a Molex to PCI-e adapter. Not sure what the FSP would do.

How soon are you in the market for this? Because if you're really looking for this much power in this price range, Seventeam and Andyson both have 700W and 800W units that are set up like dual rail PSU's, but put a PCI-e card on each of 12V3 and 12V4. That's where I'd be looking.
 
realistically by november i would be goign SLI either the 7800 gtx's or more likely i would sell my 7800 and get 2 7900's. I am open to anything after this mess with this pos liberty i just want somethign stable and will give me the ability to do a quality OC fpr both cpu and vid card... i will be goign dual core opty in about a month... i have never heard of those 2 companies? got links?


this has some more info on the FSP and soem dialogue with FSP reps.

Well... the reality is the Liberty 620W you had is a stable power supply that gives you plenty of stable power. Just because you got a bad one doesn't make it a "POS."

Of course, I can understand having a bad taste in your mouth. But you have to keep your head on your shoulders and realize that one bad power supply does not make the whole product line suck.

That said, both the Silverstone and FSP are better units than what Enermax offers. But you already have a bird in the hand. Why not RMA it even exchange? I'm sure the alternative is going to require a restocking fee, correct?

Thing is i have talked to a few people that recently bought them as well here and on DFI street, we are all having the same issue... now keep to the fact of the number of buyers that don't frequent these sites adn just go by the reviews on newegg...so i woudl say if even 4 of us just recently bought these and they all have the same problem, the entire batch migth be suffering from the same problem. if that is the case then i may need to RMA the next oen as well. it's a chance that possibly i am wrong and that i am overr eacting, thing is this is my only computer as my bro has my laptop. this is something i don't want to chance taking more time on in the case that it may malfunction again. thery had there chance and they lost it.. so the question remains strider or epsilon?
 
I understand your frustration and why you would want to get a different PSU, and perhaps that's a wise idea.

But I still think it's wrong for you to call the Liberty a POS because you and a bunch of DFI users have had a problem with it.

It's like calling the Antec NeoHE a PSO because it doesn't work with the Asus A8N-SLI.

Actually, it's not even like that because there WAS an inherent problem with the NeoHE that prevented it from working properly. In your case, the problem is just that the motherboard is a POS. Why can't this be seen the other way around?

I recently built one machine with a DFI Lanparty. Never again. Power supply problems. Power connectors all over the place making the inside of the PC look like ass no matter what. And an obstruction of the Northbridge fan by the video cards.

Sorry... But I have a problem with someone calling an entire product line "shit" because they're too blind to see that their motherboard is poorly engineered.

And please learn to use the quote tag.
 
Actually the 500's aren't as problematic as the 620 liberties. At first i suspected the MB was at fault. after swapping out PSU's that wasn't the case. i was able to get into 3D apps using a 480 watt thermaltake. Everythign ran fine, but, because of the weak amperage on the thermaltake i wasn't able to do much OCing. That said, Asus boards are also having issues with the 620 liberties. Granted the PSU worked ok when i was using my MSI neo4/SLI. Even with that board i experienced shutdowns when i tried to OC to levels i was able to do with the thermaltake. I got the liberty so i had more headroom for OCing. after that failed i moved to the DFI board. And then all the instabilities of the PSU were made very clear very fast. I didn't come here to get into pie slinging contest about a PSU i thoguth was problematic. i came here for advice about a different PSU possibility (i thought i made it clear i was done with the liberty series). ANyway thx for the help...
