yet another, what PSU?

post #1 of 12
Thread Starter 
so,

i need to upgrade from my thermaltake lite power 700w PSU

my sig rig, well not really, its more of a soon-to-be sig rig. I feel neds a good 750w+ PSU.

I will be running a 6core BD and 2 6950 equivalints. i know its very hard to decide how much they will draw because of different NM processors. do ya best

The following is in NZ$. (US$1 = NZ$1.25)

So the requirements are modular, able to handle the above and preferably below NZ$300.

this is the website with NZ's lowest prices. http://pricespy.co.nz/category.php?k...ms=l=s69938486

I do have the ability to get a 1 month old Corsair HX1000w for around $280-$300. Or a corsair HX850w for around $230.

1 last thing, whats the deal with sleeving a PSU the has capacitors at the end of the cables? Can it be done?

Given those prices, if you can get a HX850 (new) for $230, that's the best deal. It's a newer and higher-end design than the HX1000.

Especially if you want something fully modular, I wouldn't hesitate to take the Silverstone Strider Plus 750W (ST75F-P) for $228.

To power a system with two 6850 equivalents in it, a quality 750W power supply is pretty big overkill. Here are my recommendations based on this website:

actually it was two 6950's if that makes any difference to your post.

The HX850w is 7months old but i cant see how someone can significantly reduce the life of a PSU.

I actually thought the HX1000w would be relatively the same internals since they are the same series, guess not.

Any one got any info about the sleeving with capacitors?

PSU calculators suggest around 750w.

while the new egg calculator suggests around 900w?

Guess the hx 850w is a pretty good deal, guess ill see how the auction turns out.

You cannot go wrong with a x-series seasonic. Although I love my new Cougar dearly, I would still exchange her for a x-650.

ok well thanks alot guys.

Seasonic definitely gets alot of respect on these forums.

Ive decided the HX850w is probablly my purchase, just read that it was able to do somthing like 1080w. cant complain with that.

thanks.

With power supplies, it's a unit-by-unit basis. Even within the same series, there can be more than one platform used.

Regarding the HX1000 vs. the HX850: from the things I've seen here on OCN, I'd avoid the HX1000.

Anyway, even a system with two 6950s can easily be powered by a quality 650W power supply with room to spare.

AMD recommends a 500W power supply to power a system with one 6950 in it, so a system with two would get a 600W recommendation. However, these recommendations always refer to peak-rated power supplies which means even a high quality 400W power supply would be enough to handle a system with one 6950 in it.

Oh, don't go by PSU calculators. None of them are worth anything when you can lean on OCN.

Besides, even 750W is massive overkill.

I swear, I think that whoever makes those things are told to make them inaccurate just to cause the PSU manufacturers to make more money.

1080W would be its absolute maximum peak. The HX850 is an 850W continuous-rated PSU which means that it can deliver 850W continuously, but if it were asked to deliver like 1000W for a few seconds, then it could do it without a problem - just not continuously.

The same is true for every PSU we recommend because we won't recommend PSUs where their rating is a peak rating.
