Quality psu at $80 or less, able to Crossfire 5850's ?

Here is my build so far:

1. i5 2500k 3.3 GHZ 6MB Cache LGA1155 ---------------------------------------------------------------------------- $196.64 w/ tax @MicroCenter
2. P8P67 R3 LGA 1155 P67 ATX Intel Motherboard ---------------------------------------------------------------- $152.94 w/ tax @MicroCenter
3. G.SKILL Ripjaws X Series 8GB (2 x 4GB) 240-Pin DDR3 1600 - F3-12800CL9D-8GBXL----------- $69.00 w/ tax@newegg
4. Samsung SpinPoint F3 HDD 1 TB ------------------------------------------------------------------------------------ $59.53 w/tax @newegg
5. Antec Three Hundred Black Steel ATX Mid Tower ------------------------------------------------------------------$54.07 before rebate / $39.07 after rebate @newegg
5. Cooler Master Hyper 212+ --------------------------------------------------------------------------------- $33.05 before rebate / 23.05 after rebate @ Fry's


The GPU will most likely be the Sapphire 5850 for $150 that Amazon has:

Basically, the only thing that I'm kinda clueless about is the power supply. At first, I was just interested in getting a decent PSU that could handle one card, but if I'm getting this Sapphire 5850, there could be a chance that in the near future I'd be interested in Crossfiring it, so it seems that I should try to get a PSU that can handle that, so I don't also need to buy another PSU if I decide to get another 5850.

I would love a quality PSU from a company like Antec, Corsair or SeaSonic. Nothing fancy, just solid PSU. The other thing I didn't really consider though is cooling.... If I do Crossfire, can I just add more 120mm fans to my Antec 300? I'm a newb to this whole thing, haven't been a PC gamer in 10 years. Used to be a 3Dfx guy back in the days though...

    Couldn't find an up to date review of the Antec.
  3. What ever you go for, be sure its a good quality 650W, to give you some headroom, and if you have to save anywhere on your system, it should never, ever be your PSU.
  4. Antec 300 has enough room for 4 x 120mm fans and 1 x 140mm roof fan, it comes with the 140mm roof fan fitted as standard, my advice if your crossfiring, is to fit the other 120mm fans to.
  5. OOpps sorry it has the rear 120mm as standard to, so only 3 x 120mm fans needed.

    I wonder if the newer model has the fan clicking issue that newegg customers are complaining about. Anytime I see people complaining about a clicking noise or whatever, that does start to concern me. Sure, I could order it, and end up getting one that doesn't have any issues, but then again, I could end up getting one of the clickers. That's the thing that sucks when you're trying to save some $$$ on the power supply. There are tons of options out there, but you start reading the reviews, and there always seems to be a "catch" with each PSU that comes recommended. Hard to find a PSU with nobody complaining about anything. At least in my price range.
  7. I would recommend a 600-650W to be safe but I'm sure a good 550W could handle it if you really needed to skimp. No reason to though, there's 650W units available for your price.

    Good luck with the build, CF 5850s with a little overclocking are great!
  8. I wouldn't concern myself with xfire if that's the mobo you're buying it won't do x8x8.
    PRO/EVO/Deluxe will though.

    Good catch!! Didn't see that. Well, the performance difference isn't huge at 16/4 but, you're right, it's not optimal and there's other options that will deliver 8x/8x.
  10. Yep! you can buy MSI at that pricepoint that will deliver x8x8.

    Here calculate your load

    http://www.antec.outervision.com/

    Use good brand power supply such as corsair, seasonic, xfx, and or antec. You can check at internet for pricing or on sale items including internet only stores (i.e. newegg).
