Getting a 600W PSU when you only need a 400W unit (where 200W = +50%) doesn't make sense for someone on a budget.
However, getting a 1200W when you 'need' a 1000W, and aren't on a strict budget ... isn't nearly as bad of logic wink.gif

I'd say "get enough to power your system and a second GPU +20%" is a good rule. A 650w PSU can basically handle anything these days.

XFX are junky IMO.

How are XFX PSU's junk?? As i can remember last gen XFX PSU's used Seasonic internals wich clearly aren't junk.

This is a lot more than you need and it's 15$ more expensive than the Antec and OCZ units you linked, but it offers far better value than all of them and it's modular.

hmmm was pretty sure Corsair and too a lesser extent OCZ were reputable manufacturers...........realistically this rig only needs like a 350w supply but there isn't much of a selection at that size.

It's not a question of reputation... neither Corsair nor OCZ are PSU manufacturers, they sell Seasonic/CWT/FSP/Sirtec/GreatWall/etc units... and they're mostly good to excellent, with few hiccups smile.gif
However, none of the units you linked are good purchases at those prices, that doesn't makes them poor units, they simply offer poor value for the money.

Your rig indeed only needs a ~250W PSU, and that's with room to spare, but there are very few worthwhile units in that output area and none of them listed at that particular shop.

The NZXT unit linked above is indeed severe overkill for your rig.. but it's a rebranded Seasonic M12II 650W Bronze at a very good price, offering great value.

Makes sense. Unfortunately the one you linked is almost double the price of the Corsair unit. I doubt the buddy Im building it for will go for it.

So from what I linked I guess I should go with the Corsair? Since its the cheapest and you think they are all over valued anyways biggrin.gif

Damn and I just realized the one you post has a $20 mail in rebate. Im about 50% on getting rebates back to date......rolleyes.gif Maybe I should complain but the $10 or $15 dollars it usually is just doesn't seem worth the hassle most of the time...

If you can get an Antec EarthWatts Green 380D or 430D for similar money I'd suggest you pick one of those.. if not, go for the CX430
