Hello,

You should see what the video card manufacturer recommends.

nVidia sets 450 W minimum for GeForce 9800 GTX+, so yes.
AMD sets 450 W minimum for Radeon HD 4850, so yes.
AMD sets 500 W minimum for Radeon HD 4870, so this is a maybe, but probably you should choose a different product just to be sure.

Cheers,
Gabriel.

Default Corsair VX450 v Antec EA500

Hi Gabriel,

Thanks for an excellent review. It's almost enough to make me go out & buy one straight away !

Now my understanding of PSUs is a little patchy to overstate it. I attach some weight to the label on the side of the PSU where the specs are given because this label often contains info not on the suppliers website (e.g. the combined power available from the 3.3 and 5V rails, important to me because I have an old system, and because if its a picture of THE psu there can be no doubt as to what you are getting).

To get to the point, the ratngs on the 3.3V and 5V rails on this unit (Corsair 450VX) and on the almost identical Antec Earthwatts 500 are 20A and 24A respectively (please correct me if I am wrong). I'd like to know why the suppliers have quoted such different numbers for units that are so similar ? [also, why 450W and 500W]. Is it just suppliers displaying different degrees of conversatism when it comes to ratings ?

Keep up the good work !

The Antec has more current on all of the rails - 24A, 24A, and 34A on the 3.3, 5 and 12V rails respectively. The VX450W has 20A, 20A and 33A. The VX450 is internally very similar, but is just under-rated slightly. btw, both the EA-500 and VX450W are discontinued now AFAIK.

Thank you for pointing out that both these PSUs are discontinued. They are both in some sense still available to purchase though at least in the UK.

The PSUs are "internally identical except for input capacitors" so I do not see how the actual ratings could be different, I was asking whether I had to realise something, or just that Antec and Corsair had chosen to tell us different things.

Further, have Antec done something physically different to get 2 x 12V rails or have they just split the 12V output in the box and called it two 12V rails ? As the PSUs are internally identical the Antec one cannot have two sets of 12V output hardware. Is the voltage overprotection (which I assume this at the root of) done in software ?

That's cool. The VX450 especially is an excellent PSU. I do have an EA-500 sitting here somewhere, but IIRC it failed due to bad caps (which the corsair won't)

It's really a 500W Seasonic, but Corsair chose to de-rate it while antec didn't.

This is the only internal difference between the two. having multiple rails does require a few physical differences in the PCB - two groups of 12V wires, and two OCP shunts (or current sensors).

Thank you for your answers, they make things a bit clearer.

But what does IIRC mean ? I assume that it's something to do with the "inferior" capacitors in the input filter stage of the Antec....

Could you explain precisely what is meant by the term "underrated" - does it mean that the PSU is capable of more than it is labelled as ?

Doh!
