Solved

Customer support at ASUS just told me I will need a new power supply

I had called ASUS to see what the issue was with possible BSODs when running a few video applications. It mostly would happen when I had a video playing fullscreen on one monitor and then a game playing on the other one. I also have a GPU in the mail. I will be upgrading from a GTX 670 to an EVGA 780 ti. It turns out my RAM was manually underclocked and the guy had me fix that, but given my setup he strongly suggested at least a 1000W power supply.

The current supply I'm running is the 750W version:

My components are(or will be after the new card):
CPU: FX-8350
GPU: EVGA 780ti super clock (without the acx fan)
RAM: G-Skill 2x4GB 1600 mhz DDR3
Mobo: M5A97 R2.0
PSU: OZT ZT series 750W
Fans: 3x200mm, 1x140mm, 1x120mm
I typically use 2-3 USB slots. I have 3 Hard drives installed (1SSD, 2 7200), and one CD drive.

The customer support guy told me right now I probably need a new power supply WITHOUT the new card. Can you guys help me out? I'm seeing a lot of conflicting information and I'm honestly not incredibly well versed in the deeper technical stuff. I would greatly appreciate any input. Thanks!

  1. That power supply (OZT ZT series 750W) is more than enough for your specs , 1000w is overkill.
  2. No way you need a new power supply unless the on you had was faulty.

    Do not think I have seen my system pull over 350 watts at the wall(2600K @ 4.4 + GTX 670). This is not to say I would run the system on a 400 watt power supply or anything.
  3. Based on your parts you should only be drawing something around 500w max. Nothing about your build suggests you need a 1000w PS. Your 750 is perfect.

    BSODs can be super frustrating, sorry. It could be bad RAM, conflicting software/drivers, etc. It is probably NOT your power supply.

    Run a few hardware checks, see if anything comes back.
  4. The service guy also said my computer may not be getting enough power. Would dedicating one full outlet to only my CPU rather than sharing it with my monitors and a couple of other things? The outlet I'm thinking of is on a different...I don't know the word...circuit? When the fuse blows (due to straighteners for my gf and her friends :| ) one outlet works while the other doesn't.

    I guess my follow up would be "would it be beneficial if it is a power problem to separate the outlets for the tower (to the one that doesn't blow) from every other device around it.

    Is there a way to check how many watts it's pulling? I've been looking for something like this but haven't come across any, or I just don't know where to look.
  6. YOU CAN RUN that setup on a quality 650 with room to spare in the power dept.

    ASUS support was wrong , your power is fine , and it's a 2nd tier supply = decent.

    I ran a memory diagnostics test on my RAM, but I haven't done memtest (I'm at school right now) and ran my CPU through AMD Overdrive. Every time it ran through a stability test in Overdrive it failed about a minute in. I called AMD and they suggested seeing if my RAM/mobo/pus are faulty. I will be checking that tonight but I actually don't know how to tell if my Mobo is faulty. He said if all of those were fine i could get a replacement fx8350 no problem.

    Depending on your location, you outlets will only be able to push so much power, but a computer and 2 monitors should not overload it.

    More worrying is that a hair straightener(I can not see those being much over 200 watts) would.

    You can get a power monitor at the hardware store to see how much power a system is drawing(If you have a UPS, chances are it can tell you how much power you are using as well).

    I picked up one of these from a local store and while not perfect(very low loads to not show seem to show up), It does give a good idea of how much power a device is using.
  9. Some local libraries will let you borrow a Kill-a-Watt. The Library isn't just for books anymore.

    Thanks for the info.

    I believe it was like 3 hair straighteners. She had a bunch of friends over and they thought it would be a good idea to do it. Idk, i've been running my current rig just fine for the past three months. plugging it into a different outlet actually let me pass the AMD Overdrive Stability Test that I had failed one minute in prior.
  11. May want to get that looked at. If you have a power issue it is most likely not good for anything.

    As an example, Here I have 3 computers and 2 monitors along with a cable box(tuner) capture box speakers/router/3 external drives all on one circuit without issues. Now If I was to add something like a heater or hair dryer it would blow the breaker for sure(kind of surprised the vacuum does not push it over.).

    The problem in your case with power may well be something like one room sharing a wall with another sharing power. so someone in the other room fires up something power hogging and bam you loose power.
