Sorry, I was incorrect, the GS has 50mv, but still proves my argument:

T5-12V1.jpg


^^It looks about the same for all the models. And let's see the voltage regulation for the 550 GS:

3.9% on the 3.3V rail, 2.6% on the 5V rail, and 2.2% on the 12V rail. The Seasonic U1 server is way better than the GS.
 


I would be weary of assuming ripple is the only differences. If you really want to get down to the meat, it's best to research and compare two units and see their exact differences.
 


At the risk of having to admit that I agree with TS on something, I think I'm going to have to here. :)

Just because some companies insist on charging far more for their units than what they should reasonably be able to, doesn't diminish the quality of units sold by other companies that actually charge what they ought to for them that are still of a high standard.
 


1. I'm not aware of any Tier 1 quality type units in the 150-350w range, because at that capacity they really don't have to be all that great. They will rarely if ever be under any kind of demanding load and almost without exception the majority of people who would only want to install a unit of that capacity would never pay the kind of price that a Tier 1 unit, even a low capacity one, would have to fetch in order for a manufacturer to be even slightly interested in making them in that range.

The same goes for Tier 2 or "ultra whatever". If you want a high quality unit , aside from a VERY few off the beaten path units like the Seasonic Flex-ATX oddball form factor models that are lower capacity, you'll need to look to higher capacity units in the 450 and up range because it's just not a niche that's worthwhile to manufacturers. Sell ten units in two years, to the ten people interested in something that meets that criteria? Why would anybody do that when for the same price they can just grab a decent 450-550w unit and call it a day.
 


Probably better than 99% of OEM units, but not sufficient for enthusiast machines. That's really intended to be a direct replacement for a POS OEM unit.
 


I agree. No point in spending that much on a lower wattage unit. Probably the best one, in that wattage range is this Seasonic SI2 II unit.

But at its price, it is a difficult to recommend it, when for a little more, I can get this.

For a non-gaming productivity build, I'd consider even tier-3 a valid choice, given that it will never be stressed.
I'm glad that JG and others are starting to test at 10% loads, where efficiency may have really dropped off.
 
I built a system with FX-8320E+GTX 950 running on a CX430. Personally I am not scared of running such a PSU with this type of system. So far it runs alright, but I wonder how it will be in 2-3 years time.
 
As we've discussed in the past, most of us agree that from the CX lineup the CX430 is the only one that's probably not a bad investment for the price. There has been a lot of long term success seen with that unit on systems that aren't very demanding, unlike the others that people try to run on systems that should really have a much higher quality unit installed. Even the other CX units are probably fine if you're not using a high load configuration as with overclocking or discreet graphics that require supplemental power.
 
Well the XFX XT 'bastard' psu is in my case. I'm going to give it a go.

Hopefully tests turn out favorable. I'd be happy if it is at least a Tier 3, but hopefully Tier 2, quality PSU.

A Haswell i7 and GTX 950 are going in this build. It won't be too demanding for light gaming.
