Will my Corsair HX520w be enough for this build?

Hey guys, the community here has been great.

I really need help here though as I am buying parts online.

Basically doing a major system rehaul. Will my old PSU (Corsair hx520 watts http://www.silentpcreview.com/article692-page1.html) be enough to power the following system?

- i7 920 D0 possibly o'ced to 4ghz
- 3 x 2gb OCZ 1333mhz ram
- HIS Radeon HD 4970x2 2gb
- 1 OCZ 60gb Vertex SSD
- 1 Seagate 7200.12 500gb HD
- Corsair H50 Watercooling
- Antec 900 case

I've read that it should be fine however its pushing the limits or its dangerous/not overclockable. I'd REALLY love to save money and not buy another PSU if it were deemed unnecessary. I'd also not like my computer to blow up lol, stability is a must.

Thx TH in advance!!!

  1. Hi newcomer and welcome to the Tom's hardware forum.

    Can u post please the spec of the "4970x2" that u have, because I can't find it.

    Now if u refer to the 4870 here are the system requirements:

    The recommended PSU is for the entire system, so isn't enough for the 1st and 2nd one. This two are good options

    1- CORSAIR HX 650W
    2- Antec TruePower 650W
  2. Just plain no :P

    although the hx520 are a very good PSU i can't see your crossfire running well with only 520w

    I'd go for 650 at least, possibly even a 750... this is just off the top of my head though, i could be wrong...

    Here is a decent PSU calculator : http://www.extreme.outervision.com/psucalculatorlite.jsp


    Edit: oh... you mean 4870x2... not 2x4870 (or 4970x2, lol)

    yea still even without crossifre, that is a dual core gpu i'd go for at least 650 ... i mean especially since u say u wanna OC
  3. Yea so I guess she's gotta go for sale then... sigh. More money to spend boy oh boy lol.

    I was hoping someone with a near identical setup would appear and tell me hey, that hx520 does the job! Lol.
  4. Well you do have a pretty nifty PSU there, i have seen some (hx520) feed systems that wouldn't boot with a 550w generic unbranded.
    Having said that, the card pushes it over the edge, in my opinion...although you could always order the stuff now, set it up, and buy a new PSU later if you're getting problems... personally i'd save myself the hassle and get a nice or HX-650 like the other poster suggested
  5. Is the hx650 100% good for my build? It's a heck of alot cheaper than the 750w one so I wanna be sure lol
  6. U should not be to worried with the HX650W since that PSU is enough for the rig even with OC.
  7. hx650 should be 100% good for a SINGLE 4870x2... if you're planning to crossfire... then that would be pushing it... especially since you say you want to OC

    Edit: Depends what kinda budget you're on..

    Edit2: check these out

    http://www.shopbot.ca/xfx/power-supply-units/housing-and-cooling/canada/111/b/184

    These are quality.. a bit too shiny for my taste but quality nonetheless
  8. Are there any other modular or good budget power supplies other than Corsair? I'm in Canada.

    Sorry I am REALLY lacking in psu knowledge.

    How's this OCZ modular one?

  9. Hey guys thx for the links. I cant see the first two newegg products saint what are they?

    So the top brands are Corsair and XFX? What's wrong with OCZ I buy their memory lol and it is 80% efficient too!
  10. The top brands are IMO:

    Corsair
    Antec
    PC Power and Cooling
    Silverstone
    Thermaltake (not all series)

    The 1st two links are from newegg canada and are this:

    1- Antec 650W
    2- Corsair 650W
  11. Yeah, the 650W is enough for the rig that u want with OC.
  12. So should I be aiming at a 650w? I'm looking to use this system for a few yrs and I'd definately wanna buy something with ease of mind with the ability to run stable AND o/c.
  13. How are XFX and PC power and cooling?
  14. PC Powe and Cooling is very good too, but XFX isn't as good as Antec or Corsair IMO.
  15. I would go with the Silverston from directcanada.

    How do you put Silverstone and Thermaltake on that list but not Seasonic and Enermax? Silverstone at least deserves to be mentioned but Thermaltake?
  17. The one thing I have against Antec psu is they sell them as modular but with like 2 modular cables lol... I'm leaning towards the Silverstone Strider plus too. Think that will be future proof for Crossfire as well? How does it pit against the Corsair hx650?
  18. ^The Antec is better.

    It might actually. Corsairs are underrated PSU's. Thats why they perform so well. It would support 600 watts.

    Still, I wouldn't feel comfortable doing it. If this was one GPU, I would say no problem. The second one scares me.

    Bottom line, it would likely work. But I'm with everyone else. I wouldn't do it.
  20. Which Antec series are better? TP, Earthwatts or Quattro? Wow don't know which one to get lol.

    Or should I just stick with the Corsair hx650? Or the Silverstone decathalon or Strider?
  21. Ante new TP, Earthwatts and Quattro are very good all depends of ur needs.

    U should go with the Corsair HX650W since is a good price/performance option.
  22. Yeah, because is Gold Certified.
  23. Would you say the Corsair hx650 is a better option than both Silverstones? (650W Decathlon and 750w Strider plus)
  24. you forgot seasonic wich in fact are the suppliers for pc power and cooling,corsair and xfx

    http://ncix.com/products/index.php?sku=52176&vpn=M12II%20620&manufacture=Seasonic%20Electronics
  25. Ok guys so I've narrowed it down to these based on price and some reviews. I've decided against the Corsair HX650 and instead will rule it out with the HX750 just for future upgradability and the prices are similar:

    Seasonic M12D 850W: http://www.ncix.com/products/index.php?sku=35155&promoid=1031
    Corsair HX750W: http://www.shopbot.ca/r.html?catc=2&refproduct=184770&refshop=2098&refshopcodeid=9372694
    XFX 750W Black Edition: http://www.bestdirect.ca/products/225030/XFX/P1750BCAG9/
    Silverstone Strider Plus 750W: http://www.directcanada.com/products/?sku=22170AC0247&vpn=ST75F-P&manufacture=SILVERSTONE%20TECHNOLOGY

    Or am I wasting money and a Corsair HX650 will suffice? I WOULD like to add hard drives or upgrade to Radeon 5xxx or 6xxx one day.
  26. Out of that list i would personally buy the SS Strider+ 750w, but that's just me... the seasonic you listed seems like a great buy, but the reason it's cheaper than other models is because of the silver rating and dual 12v rails instead of single 12v rail

    Edit: man if you're willing to pay the extra $$$ for the HX750 then do it you wont look back
  27. I read on a forum, someone said that this Coolermaster is really underrated http://www1.canadacomputers.com/product_info.php?item_id=026508 as its made by channel wells or something... Hmm everyone seems reallly high on Corsair, I'd really love to not break the bank if I have to lol.

    The others are Silver rated as well, and since when does adding an over current protection circuit equate to making something cheaper ?

    Re-read my post... i said it's cheaper than OTHER MODELS (meaning other 850w PSUs) because its SILVER RATED and has DUAL 12v instead of SINGLE 12v... i didn't say anything about OCP.. or about how expensive/cheap that model is to make.


    edited for typo..

    No need to re-read your post.
    The post you responded to didn't mention any other 850 watt units it did mention Silver rated 750 watt units, so how would anyone other than Miss Cleo know that you " meant other 850 watt units "?
    No , you didn't really mention anything about OCP, you did say it was cheaper due to being dual rail and dual rail in it's case is created by adding an OCP circuit.
  31. Ok guys I've narrowed it down to:
    Corsair HX750 at $160 after tax and shipping and Antec TP750 New at $127 after tax and a 20 rebate.

    What is the better buy?
  32. there aint noting between the hx750 and xfx 750 take the cheaper one
  33. Any ideas? The Xfx will be $5 cheaper than the Corsair at $155 lol

    To me the 5 buck difference there is a 5 and 7 year warranty.. man this is a hard decision lol.

    Bro i don't wanna derail the thread but you clearly do need to re-read my post as what i said was

    Assuming 'Anyone other than Miss Cleo' knows the first thing about hardware, why would they think i meant anything else...; Why would i be comparing it anything other than 850w PSUs... that's would be like comparing a 250gb hdd to a 300gb...

    There is barely any difference between them (except looks obviously) but i'd say go with corsair for the longer warranty :)

  36. Ok so everyone give the thumbs up on the Corsair HX750!
