Ideally I would like to run either a GTX 570 or a Radeon 7850. I have time to think more about which one I want because first I need a new PSU. I'd like to spend around $75 and have come up with a few already from brands whose PSU's I've never owned before.

Some brands that I've looked at are:

Rosewill Green Series: With 600w on the 12v rail for $60 I've looked into this one the most. Anything else by Rosewill that I've ever used worked for me.
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Antec NEO ECO 620C 620W: I currently run an Antec Green, but never a NEO branded one.
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Corsair CMPSU-600G 600-Watt Gaming Series: Never owned anything by Corsair but they're apparently the best there is.
http://www.tigerdirect.com/applications/SearchTools/ite...

Ultra LSP650 650-Watt Power Supply: The reviews on anything Ultra branded are outstanding but, what bothers me about this one is that it has very low power on the 12v rail, I'd think about going for the 750w instead maybe.
http://www.tigerdirect.com/applications/SearchTools/ite...

Then I've also looked at different Rosewill HIVE series, some RaidMax branded ones, a few Cougar models, and a Vision Tek.

What do you guys think of these? Do you have any other suggestions for me? Remember I want to run a GTX 570 or a 6850 so it needs to have 38amps on the 12v rails. My motherboard only uses a 4 pin to power the CPU so I'm not sure if dual rail ones will give it the full power or not, therefore I have not looked at to many that have 2 12v rails.

wouldnt say corsair were the best there is but certainly good

its not wattage on the 12v rail its the ampage you need to look at

recommended for a gtx570 is 550w and 38 amps on the 12v rail

Yea i understand its the amps but I always just multiply by 12 and find the watts. So it really only recommends 38 amps for the 570, and then the 6850 should be lower than that so I guess I could save some money and look at some lower power PSU's then if I wanted to (I don't really want to yet).

For Corsair, I think it depends on the Line. The AX line is probably one of the best if not THE best on the market hands down...The HX and TX line are one of the best (not full sure but thats what I hear from professional reviewers and such), and the CX/GS I'm not sure, but I've used CX before and they haven't failed me.

Certain lines from Antec are excellent as well as seasonic.

Yea people like seasonic but their stuff is to much money for me, I'd only be able to afford, I think it was a 480w and that won't cut it.

silverstone are more known for their pc cases--only ones i have seen where the motherboard is rotated 90

degrees

its a reasonable psu but would probably go for corsair if the prices were similar

Not sure how I missed this Kingwin ABT-750MM Maximum Series for $60. 750w, and 55amps on the 12v rail, I guess I over looked it because it doesn't have any reviews but the 650w version has good reviews and Kingwin makes good stuff right?

Says it's selling out so don't buy it I might want one. :D

Kingwin don't make PSUs, in fact very few PSU brands do, and their good ones are generally restricted to their 80 Plus Gold and Platinum rated models.

Hopefully it does sell out because then you won't be able to buy one. It is a low end/old, inefficient design I would recommend not buying it.

For around ~$75 these are best units over 500W:
XFX Pro 650W Core Edition 80Plus Bronze $75 ($10 rebate)
http://pcpartpicker.com/part/xfx-power-supply-p1650snlb...

Antec HCG-620M $70
http://pcpartpicker.com/part/antec-power-supply-hcg620m
This is basically an upgraded Neo Eco; it uses the same Seasonic S12II/M12II Bronze platform, but it uses higher quality parts, such as Japanese capacitors throughout and it has higher efficiency. It also uses a larger 13.5cm vs a 12cm in the Neo Eco.

Steer clear of Raidmax and Visiontek althogether, the Cougar units in your price range are not good units either.

Remember that often the recommended wattage/amperage figures for systems with a particular graphics card are often inflated to account for a number of things, such as low quality PSUs, very power hungry systems etc, so usually you can go below the minimum recommendation aslong as you know what you are doing and don't mind 'restricting' your upgrade options.

I agree that the kingwin is outdated I noticed that it didn't have an 8 pin EPS connection, but my board doesn't need one so I didn't think that it would matter very much at all. That XFX one seems very decent, I never looked at it because on Newegg it was like $90 but that NCIX site has really good prices on stuff. I will have to remember to look there more often for things I can't find off of tigerdirect or newegg. Thank you :D
