I need a new PSU. - Page 5

post #41 of 62
In older versions of the ATX specs Intel had required the CPU to have its own rail separate from the motherboard and other components. It had also specified that no rail have more than 240 VA available(20A @ 12V), this is what lead to multi rail power supplies in the beginning (this is the reason why I called this setup outdated). Then time had passed and new powerful videocards and CPUs come to the market. With old PSUs this lead to an issue called "trapped power" or even cause PSU shutdown by overloading any of it's virtual rails. (For example old multirail 550W PSU (gps-550ab-a) won't work normally without correct redistribution of virtual rails with gtx 580 videocard) So the newer PSUs come with one "fat" +12V rail to solve this problem.

Multirail PSU vendors simply increase the OCP value to 30A or even 40A in their current products to minimize posibility to encounter mentioned above issues but the sheme roughly remained old.

You don't really have to know anyway. Mike already listed several specific examples.
I see no good PSU there and I answered why above.

This 1000W PSU has 40A OCP per each virtual rail so in common conditions it rather difficult to shutdown it by overloading any of its rails or encounter "trapped power issue". But this scenario is still easier than to try to overload single 83A OCP of Seasonic Platinum 1000W for example. Also it's impossible to encounter "trapped power" issue with monorail PSU.

But i don't find a reviews.
Well you pretty much said everything about it. Its a seasonic G-series underneath the exterior. Fully modular. A very very good unit, especially for the money. thumb.gif

Did I say "good"? No. I said "modern".

 

Geez. Just forget it, dude. Good lord. Talk to Mike. He knows more than I do. Ok?

 

Anyway,

It's a SeaSonic S12G, which is a very solid PSU. I'd say that it's better than the other ones that you were looking at before.

 

However, a PSU's 80+ Certification has nothing to do with its quality.

I dont even....

You just talked a whole lot about PHYSICAL rails not VIRTUAL rails that you keep referring too. A virtual rail basically has a special transformer that has a mini-computer in it. Basically, because I dont know the technical stuff on it, it will regulate how much wattage will go to each rail. I'm not totally sure how, but I do know your talking about physical rails in this post, then mentioning virtual rails for some reason.

Yeah, he doesn't really know what he's talking about. He could convince someone who doesn't know anything about PSUs though, that's for sure. He's not fooling me though. lol I just don't want to waste any more time on the argument because this is Sayson's thread, not defcon5's.

Well, finally I bought on amazon the Corsair RM650. I hope not to have problems, If there are any problems, I can request a refund and buy another PSU.
I chose the Corsair RM650 because is Gold80 +, 135mm fan hybrid, full modular, good performance, and has 5 years warranty.
For that price(100€) I could not find another power supply with similar specifications.
I just hope I get it right.
Thank you all.
I will comment on results.

I am curious:

 

Why did it have to be a Gold certified PSU?

 

Why did it have to be Fully Modular?

Seasonic G or Cooler Master VSM or a lot of others units are much better in the same price range
