hi i had a post earlier asking about an Aopen PSU which is 750 watt two 12v rails with 30 amps each and it has a 3 year warranty and it is modular and was made by FSP (which apparently is good) this PSU is R968 which is $140, now there is another PSU that i could get which would really stretch my budget its a Antec CP-850, 850W Quad 12V Rail which is modular and has a 5 year warranty and it is R1372 which is $198, do you think that antec PSU is worth the extra $58?

thanks

Not trying to be a jerk or anything... but next time could you preview and reread your post before you submit it? I had to read through it a few times to understand what you were trying to say. But if you are looking for a 750w or 850w PSU, look at the links below.

Those aren't the most aesthetically pleasing units around but they are good quality and do the job.

I live in South Africa so I have very few options, as most PSUs are overpriced (as are all components in S.A) i have been looking around for a long time and i have not found anything better at those prices

I dont even think we have xfx PSUS in S.A, corsair, antec and seasonic are overpriced here in S.A, but i saw that antec PSU and its at a good price, its like the same price as a corsair 650 watt in S.A

That PSU only fits certain cases, but if it fits it seems a good psu.

Quote:
This power supply model is very unusual in that it has a form factor — CPX — which makes it compatible only with a handful of cases, namely the Twelve Hundred, P183 and P193 cases made by Antec. Partly because of its narrow target market, the CP-850 has not been quite as popular as it might have been with a more universal form factor.


Do you need 850w, otherwise a 750w will be cheaper and you can't go too far wrong with the Corsair.

the 650 watt corsair costs the same as that antec 850 watt, and that antec 850 was stretching my budget, il guess il just go for the AOpen PSU

It depends what you need, the Antec is good but you need one of the above cases for it.

Whats the model of the AOpen.

I've had a look at your other thread, the AOpen should be enough for Crossfire if needed.

So as far as I can see you have 3 choices.

1. Buy the Antec which is a good psu and get a new case for it to live in.
2. Save up and get the best psu option, the Corsair and it will last you years.
3. Buy the AOpen which isn't the best psu but seems ok and will power your system.

Is the 750w Corsair a bit cheaper, don't think you'll need 850w.

You would think they would all scale the same (price wise)when being sold over seas but not sure.

If you going to crossfire, you should buy a good quallity 650w or higher from Seasonic,Corsair,XFX, and newer Antec.

well it depends shops are cheap and some are expensive (if the cheap shops dont stock that specific PSU then but the expensive one do then obviously it will be expensive...) there are like only 6 online shops in South Africa that are cheap, and the sad thing is we are so far behind in a way some people here think that core2duos are still beast haha

not always. often you might see a CWT Corsair unit go for 10-15% more then the same unit with a thermaltake name on it, in North America. Out there it could be 50%+ more since there is little supply of the popular PSU brand names. People from Pakistan, India, other parts of Asia, and Eastern Europe complain about the same thing. This also brings up a great question of why they would ask shopping advice on a board where most people shop in USA, Canada, UK markets.

1. FSP makes some good PSU and some bad one, I'm not familiar with the AOpen brand.
2. can you please post your PC specs because its impossible to comment on a PSU recommendation without them

well then I'll put it this way

the Aopen 750w will be fine for an SB i7 & ATI 6870 or 6950.
http://www.aopen.nl/products_detail.aspx?ctgr=56&Auno=2...

but if you can afford to pay for a brand new SB i7 and dual 6870 or quad 6950 (its already a dual GPU card) then you can afford a better PSU.

the hd 6950 is not a dual gpu card... its the replacement for the hd 5850.....remember ATI changed the naming scheme, the dual gpu card is the hd 6990 which is the replacement for the hd 5970, then ther is the hd 6970 which is the replacement for the hd 5870

I know a good one may be expensive, but the PSU is not where you want to cut corners.

If your not willing to pay the extra for the top brands then I think you've found your answer.

I don't blame you, that is pricey but if it was me with that system I'd be getting a high grade psu. ;)

here look at this it has all the info on the AOpen PSU http://global.aopen.com/products_detail.aspx?Auno=2970



FSP does not have a 750w on their web site. they have several 700w units, one of which is re-branded as the Aopen 700w. The FSP 700w units are in the 50-56a on the 12v rail (the Aopen 700w is 56a).

Aopen does not post total 12v power stats but I would guess that with 30a on the 12v1 and 12v2 split, its also a 56a on the 12v unit.

...yeah I forgot ATI decided make Nvidia naming schemes look brilliant. an FSP 700w can run the ATI 5850 in CF, you wont draw more then 500w even with a OC CPU.

that corsair PSU is over double the price of the AOpen one which is about $140, do you really think its worth it?
