They are the same design, internally; but higher wattage units based on the same design generally have more powerful components on the inside to deal with the more powerful output.

So in regards to the internals of PSUs, is there any difference between, say, the XFX pro 450w and 550w (lets assume v1 450w to keep things simple)? or cx 430 or cx500? I mean if they are same internals, aren't basically psu companies just selling the exact same psu as the 100w higher version, ie xfx pro core 450w vs 550w? And then just add a few cables or something?

I know wattage/amperage is meaningless, but what I'm wondering if literally like the xfx pro 450w is the same psu as the 550w. And the same im sure happens with lots of psus, like cx430 and 500, etc, i dont want to speculate but you get the idea. If this is the case, why not just buy the cheapest of same internals, basically.

More specifically, i bought an xfx pro 450w v1 for $45. I'm thinking of just selling it and getting that newegg xfx pro 550w for $39 AR, but if they are identical internally then I won't bother with the trouble (xfx pro 450w v1 has 2 pci-e cables, so no issue like that, i also heard someone say v1 has ocp whereas v2 doesnt but im not sure?).

Units within the same line but with different wattages will obviously have visually-similar internal components. The thing is that the makers of those sub-components (Nippon Chemi-con, Teapo, etc.) make a wide variety of seemingly-identical (to the untrained eye) parts that are rated to different capacities, with higher-capacity parts costing more than their lower-capacity counterparts.

In short, there's more to making a 550w PSU than slapping a different label on a physically-identical 450w unit. While they use the same platform, higher-capacity parts are used within to handle the extra juice.

Note that this only holds true for models in the same brand and line. A 450w model of "Brand X" may have weaker internal components than the "Brand Y", even if OEM'd by the same manufacturer. Same goes for two different 450w models from the same brand but different lines.

Thank you for creating this list. I just got the CoolerMaster Silent Pro Gold 1200. Thank you to everyone that contributed to this list.

The difference between this new CoolerMaster and my older CoolMax CUG-950B was like Night and day.

I ran some test and discovered:
1. My USB wifi adapter increased to +3 Mbps (now I'm at 10Mbps).
2. I no longer hear a loud "click" noise when I double click on the icon for my 2nd hard drive.
3. My music folder (which has over 500 songs) loads literally instantly. Before it used to take a while for it to load up.

I haven't bench marked my games yet. But see the improvements on regular desktop usage, I"m sure my crossfired 6850's will be very happy. Now I can go ahead with my new build with confidence (Triple Water cooled GTX video cards looks really appealing now).

I wish this list was hear back in 2009 when I purchased my CoolMax, that fake 950 watt (but really 700 watt) PSU would have never powered three different rigs.

Its a good PSU but a bit overkill for a 2 way crossfire setup

Anyway at least you have power enough to power just about anything now

edit: so should i try to sell off the xfx pro 450w v1 for ~$40 on ebay and try to buy the newegg xfx pro 550w, or what? I mean it's not much trouble, I think I'm just going to do that if the 550w is better.

actually I might be able to get a rosewill capstone 550w modular for $40-50, or a rosewill capstone 450w for $44. I think I might do that instead.

Now i'm assuming that'd be worth the trouble of just reselling off the xfx pro 450w for ~$30 after shipping lol.

I just need to know, will rosewill cover an RMA if it's used (i see their official policy is no, but practically, what happens?).

I have a $20 off coupon for ebay (and newegg sells on ebay too).

So my thinking here, is sell the xfx pro 450w I bought for $45, on ebay for ~$25 after shipping.

Then buy either:
rosewill capstone 450w $44 (from newegg@ebay, so it'd actually be covered)
rosewill capstone 550w $40-50 (from random guy, but he has the original newegg receipt).

I think I'll go with the 550w, even if it's $6 more. hey, modular so whatever. If I have the original receipt, then that should be covered under warranty.

Anyway at least you have power enough to power just about anything now


I agree it is overkill for 6850 crossfire.

But,...

I'm hoping to get Three GTX 670 with my next build. I will also be getting three 22" 1680 x 1050 monitors, so this power right now is overkill. But by June it'll be "just right". I also plan on water cooling the three GPU's.

May i ask why you would go for 3 1680 x 1050 monitors when you can buy even a good 27 inch 2560x1440 monitor for around 700-750$ US the korean 2560x1440 monitors are even cheaper then that
