Is this psu any good

From what I read it doesn't even have any PFC. At all. :o

Let me find where I read that...

It has 0.99APFC. About as good as you can get. It also has excellent ripple suppression and voltage stability. This is a very decent PSU for the price.
 
It has SamXon capacitors. The minimum quality level you want to see in a good PSU would be around that of Teapo, and these don't meet it. Granted, there are worse ones out there than Samxon, but they're far from the best.

However, that's not the worst part. I'm copying part of a post OCN:

That bridge rectifier is rated for 3.5A without a heatsink, which means this unit would max at 400W on a 115VAC line. Yeah, 430W my ass. That's anemic for a 380W.
*snip*
So you know why a bridge rectifier that can handle 400Ws is a problem here, this unit is placed before almost everything else, thus is going to have to supply all the power that's wasted as well. In other words, it's placed before most of the efficiency losses. So 400W * .78 (since this isn't 80+) gives us 312W. Which makes this somewhere around a 300W power supply. .

That is a bit of a daft post to be honest by the OCN guy, saying it is really only a 300W PSU is like saying an 80% 850W unit is only really a 680W unit. People take into account the amount of energy wasted when they say 450W or 500W or whatever else.

For OP, it would be a perfectly fine unit. 312W - 59 for the video card = 253W
-95W for CPU = 158W

there is no way that the motherboard, memory, hard drives and optical drives are going to be pulling anywhere close to 160W between them.
 
No, it isn't. The rectifying bridge is before most of the power is lost. Its maximum current would limit power input, not output. In the same way than an 80% 1000W unit actually draws 1250W from the wall, this ~310W draws ~400.

It's still not a 430W power supply, regardless of weather or not it can power the system. And it still has fairly low-quality caps. These are around the same price, and are better units in nearly every way:

True, except that in this case the rail can handle more wattage than the entire PSU. :/

Dont really know what that means?

The 430 isnt a bottom of the dump power supply. Decent for the price. But it isnt what the 400 was. Not only going from Seasonic to CWT, the quality was lowered. Plus more wattage was dumped from the 12V to the 5v/3.3 rails.

I thought it was just misleading for Corsair in the change to call it a 430 leading people it was a upgrade from the 400. When in reality it was a downgrade in wattage on the 12V and quality.

I meant that the rail can handle 336. But, that rectifying bridge can't even put out that much for the PSU to turn into usable power.

I agree it isn't bottom of the barrel...that honor goes to Linkworld. But, it's definitely not up to our standards, and if any other brand had put out that same product we wouldn't look twice at it.

You are confusing lower quality and poor quality.

The CX430 is lower quality than the CX400 which it replaced, but is by no means poor quality when compared to the worse units. As has been said, it is priced accordingly, only fools would look at the lower price for more watts and not think of looking at why that is the case, or assume that the quality has dipped. It is, for a basic build, which for the time being OP has, a good unit, and arguably the best for its price
