PSU 12v amperage - Page 2

post #11 of 30
The Rosewill is a kind of mediocre ATNG unit. Not terrible but not great, and more of a 450W than a 550W. Still shouldn't be shutting down on you since you wouldn't hit 450W load with your system no matter what the overclock.

You could try a SeaSonic M12II 520W:

Exactly. If we have to recommend or mention a unit with an anemic +12V rail we'll make sure to tell you its effective wattage. Like how that Rosewill 550W is more of a 450-500W, and the CM Silent Pro 700W is more of a 600W. Etc. And I'll say "more of a XXXW" instead of "is overrated" because in these cases they can provide their rated wattage, it just assumes an unrealistic load on the +5V and +3.3V.

That rosewill psu should be able to handle what you have even OC. How long you have it. Maybe start to go down. On other hand, may take a look at the OC settings you have at 4G, things such as ram timing or NB voltage ( need to increase a bit when ram run at high speed or use power hug GPU) etc.

this one? It seems like it would be fairly good. Modular and everything. I like the discount too. Anybody have any opinions on it?

This one looks ok, but it doesn't state the amperage even though you say it doesn't matter. Also I would rather have more than I need than not enough. Plus this one is only 520W. And its about the same price as the other one.

I also like that the other has 2 6 and 2 8 pin PCI connectors.

How are cable lengths on both of them? I need some fairly long cables for my case.

That Antec New TP-650 looks good. If you start adding new components and may replace a single more powerful GPU, this unit is the way to go.

It has 40A on the +12V rail.

I'm no power genius, so why do you say amperage doesn't matter?
