Is this a good power supply?

I am debating which power supply I should get as I am building a new system. These two are on top of my list,

the XFX pro 650w which I saw a really good review at

the second one is the OCZ 700w

I haven't finished buying all the parts yet, so far I only bought the XFX 4850 1GB video card. The CPU will either be a AMD 6 core or one of the powerful quad cores. I will need about three hard drives, two dvd drive, with about 8 GB of memory. one video card is enough for me.

my question now is the 650W have enough juice for a system like that? Any suggestions will be appreciated, thanks

More about good power supply
  1. 650w is much more than enough, and with a 53 amp output on the 12v the XFX is actually more powerful than the OCZ 700w ( 46a )
  2. 636w on the +12V rail (XFX PSU). That is all you need leaving headroom for capacitor ageing and future upgrades, probably even CFX.

    I would certainly take the XFX over the OCZ, it's more powerful and receives better ratings/reviews.
  3. I'd probably go with the OCZ. I absolutely love my ModXStream 600w, but although I hate to admit it, the XFX seems to be a slightly better build unit. The 53 amp output does make it a little more powerful than the OCZ unit...
  4. Go with the XFX--they make better PSUs.

    Go with the Quad core if video editing isn't your focus. If you're interested, you can do a post for a full build.

    Are you sure you want two DVDs? I've had that before and it's nearly useless--definitely not worth sacrificing something like better graphics that you'd use regularly.
  5. Do not select the OCZ ModXStream Pro OCZ700MXSP. It is made by Sirtec for OCZ with components of questionable quality. It won't deliver its claimed capacity of 700 Watts but it will deliver 80% of it.

    The XFX Core Edition PRO650W is definitely a good unit with a Recommended rating by JonnyGURU.com.

    Not to mention the XFX power supply units are made by Seasonic which are world-renowned for being reliable and powerful, very well built.
  7. Generally, you want to check Jonnyguru reviews for any PSU you buy. You can skip that for the top brands though (which does not include OCZ or Thermaltake).
  8. sorry, guys. I've been out of the country for a while, sorry I didn't reply to any of you sooner. I found another xfx 650w with a different model number from before, XFX P1-650X-CAG9, I also provided the link below

    http://www.newegg.com/Product/Product.aspx?Item=N82E16817207002&cm_re=xfx_650w-_-17-207-002-_-Product

    is there a difference between this xfx 650w and the xfx650w at my opening post? price wise, the new one I just found is $30 cheaper because of rebate.

    I am thinking of going for amd 6 core or amd high end quad core. I don't really need 6 core for now, but since the there is not much difference in terms of the price, and I want the new built to be future proof, that is why I am leaning for the 6 cores. once I am done choosing the power supply, I will choose the cpu and the motherboard. Is this a good motherboard for amd 6 core?

    again, thanks for all the helps, guys. Any suggestions will be appreciated.

    They are both from XFX's XXX Edition Series. The only difference between the two power supplies is:

    Model#: P1-650X-CAG9 has a neon green fan

    Model#: P1-650X-CAH9 has a black fan


    The motherboard should be fine. The M4A88TD-V EVO/USB3 CPU Support List says it supports:

    Phenom IIX6 1035T, 1045T, 1055T (HDT55TWFK6DGR and HDT75TFBK6DGR), 1075T and 1090T
  10. thanks for the feedback, ko888. But the ps from the original post is actually a different one, P1-650S-CAB9

    is the 650w good enough for a amd 6 core built?

    thanks

    thanks for all your replys , dalauder. Can you give me some feedback on the parts I've chosen so far, amd 6 core cpu, the asus motherboard, the xfx650w powersupply?

    in terms of power supply, I was just wondering if there is a difference among these three xfx 650w models? which is the best among the three?

    or if u have other recommendations for my build? thanks

    Sorry. The P1-650S-CAB9 is from the Core Edition Series. It's better than the XXX Edition Series P1-650X-CAG9. It doesn't have the ripple issue on the +12 Volt rail during crossload that the XXX Edition Series has.

    650 Watts is sufficient for your system configuration if you're using a single Radeon HD 4850 or two Radeon HD 4850 in 2-way CrossFireX mode.

    thanks for the reply,Ko888. So the P1-650S-CAB9 is better than the other two xfx 650x units? Do I get to save more power by going for the P1-650S-CAB9 as it's more power efficient? I will be using only one HD 4850, will probably get one boot up drive of 500GB, and two 1TB drives for storage.
  14. Honestly, you are thinking way too much for powering a single 4850.. Any good 450W PSU will do the job pretty fine.. If you have future upgrade plans of moving onto some bigger and better video card then think about getting a 550 or more wattage PSU.. If you want to get the best available for about 100 USD then get the Antec TP New 750W..
  15. thanks for all the feedbacks, appreciated.
