PSU for New Rig

Hey guys!

Im looking for the last part for my pc upgrade, and the only thing i need is a 650W Psu...

im gonna run:
3570K Overclocked with fan
Asrock z77 extreme 4
7850 Possible CF in the future
Samsung 830 128gb
WD 1000gb
Corsair Vengeance 2*4gb

I've been over some different kind mostly Corsair Seasonic and Antec. it would also be nice if it was moduler.

Thanks

  1. If you're potentially going dual GPU in the future, get a 750W PSU. Anything from Antec, Seasonic, XFX, Corsair, Be Quiet!, Silverstone and Enermax will do you.

    Okay if i'm raising it to 750W Will there be any difference between the 650 and 750 units?

    Rugger:
    I'm probably around the 135$
    Also i heard the cables on the ozc psu are pretty short is this true?
    Else i'm currently considering those: http://www.edbpriser.dk/Product/Compare.aspx?clist=6309714;512689;701553;535200
  3. Short is relative to the case and how you route the cables. The OCZ would be my last choice on that list. It's a good PSU at a great price point so I had to throw it into the mix. I've used the 500W version of the ModXstream in my Antec P183 and had no issues with any of the cables reaching their destination and that was routing everything behind the mobo for a clean interior. If you've got a full tower then take a closer look at the cable lengths; the P183 is big but not a massive full tower.

    I respect Diellur's input on PSUs but I think you'll be good quality 600-650W PSU. The HD 6850s were more power-hungry and they only needed a 600W with 40A on the 12V rails.
  4. Is that 600W with CF?

    I'm looking over http://www.newegg.com/Product/Product.aspx?Item=N82E16817341052 quite a bit.

    Also i got the Antec P182 which is 21.3'' x 8.1” x 19.9”(HxWxD)
  5. Yes, 600W for a CF. A CF of 6850s with a highly overclocked i7 965 used 393W at full load: http://www.guru3d.com/article/radeon-hd-6850-6870-crossfirex-review/4 Your 3570K and other components won't draw anywhere near the power that i7 965 drew.

    You shouldn't have any issues with the OCZ ModXstream PSUs with a P182. The OCZ ZT series is good; the 3.3V and 5V voltage regulations isn't great and Johnnyguru said some of the soldering was not good, but it got a 9 and is recommended by them. http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story5&reid=262 I would definitely go for the ZT series over the ModXstream.

    I'd personally go with the Seasonic, Antec, or Corsair I linked above...they are high quality and sufficient for your system.
  6. Okey so, im not quite sure whether to go for 650 or 750, but if i go 600 i'm probably going to pick up the Antec HCG 620M

    But i don't know which to go for if i should go for a 700. Maybe the XT750.
  7. The Corsair TX750 is a great PSU and the OCZ ZT 750 is a really nice PSU...both are overkill for your system even if you go CF with the 7850s. 600-650W with 40A on the 12V rails is all that you need; that Antec HCG 620M is a great PSU. I run an i3 2120 and an HD 6950 on a Seasonic M12II-520; it's the little brother to the M12II-620 that I recommended. It's quiet and has rock solid rails. You would be good to go with either the Antec or the Seasonic.
