What wattage PSU do you recommend? Computer is going to be for multi-monitor use - 6 monitors. Build below:CPU: i

What wattage PSU should Computer. This computer is going to be for multimonitor use - like 6 monitors.
Build below:
CPU: i7 4770k (slightly overclocked)
Mobo: Gigabyte z97 ud3h bk - Black series
CPU cooler: Noctua Nd14
SSD: Intel 250gb SSD
HD: One sata HD
GPU: Visiontek HD5570 SFF 4-port VGA VHDCI 1 GB x16 PCIe Graphics Card
Ram: DDR3 Corsair (2x8gb) [Slightly overclocked]
6 fans, not including the two on the cpu cooler.

My total wattage guess is 350.
Then I'll add a regular GPU card on to it later.
From my knowledge and research a power supply runs optimally runs best at 50% of what it can put out.
I was thinking of putting a 750 corsair modular, overkill but when I add more monitors or another card.

More about wattage psu recommend computer multi monitor monitors build cpu
  1. Now the all monitors don't really count, unless they are getting power through the PC, which I have never heard of. They all have a power cord to a electric socket, correct? If so (its got to be), then the monitors won't be taxing the PSU.

    The current system could run fine on a quality 400W PSU. Most bad quality PSU run at about 70%. A 80+ PSU will run at 80%+ (Source).

    Now the PSU you buy now depends on the that you are going to get. Like even GTX 780 Ti SLI can run fine on a 80+ 750W PSU.

    Also, while looking for a PSU, you should go by this very useful list. http://www.tomshardware.com/answers/id-1804779/power-supply-unit-tier-list.html
  2. Lol, someone just tell me what to buy. I'm tired of researching. Something on sale, and $70.00. I originally purchased the corsair 600m. But figured I can get a better one for the same price $70.00. Intended on returning the 600watt and get the 750watt for the same price. But now the price changed on micro center.
    So price $70 (Mail in rebates, sale w/e)
    Quality/ bang for buck
  3. What about this 80$ but I wont go any hire. It's tier one from the list. Opinions?
    Dav wouldn't that 850 be absolute overkill for my needs? 850 x .8 = 680watts/2 = 340watts at 50%
    Maybe not?

  4. If you can stretch to 80$ and don't mind the MIR, it look like a very good deal. 10 years (!!!) warranty, 80+ gold and fully modular.

    Edit: just seen that it's the older G1 model (as opposed the newer G2), not sure who's the OEM on this one... I'll get back to you in a sec.

    Edit2: After looking at a few reviews for the EVGA, its seems that the G1 is based on a much older platform. The features and price are nice, but its performance might be inferior... I'd go with the XFX personally.
  5. Yeah damn it I noticed still searching. I just want a 750 watt 80 bux. Gold standard preferred. From the tier 1 list
  6. How about the Rosewill Capstone? Very well reviewed, 750W 80+ Gold, Modular and 7 years warranty. 100$-20$ MIR.

    And what is this list you are referring to?
  7. That's not a bad one. Leaning towards it. Getting tired of looking thanks for helping. :D
  8. Best answer
    I've never heard of the only 50% real performance. In some cases that is actually true, with like the $12 300W PSU. Really, all normal PSUs above $25 get atleast 70% real performance. I could be wrong, but I have never heard of only 50% of real performance.


    Tier 1$109.99

    Tier 2 (Class A) $68.98

    Tier 3 $59.99 with $10 rebate
  9. I scooped the Rosewill it'll be straight. Thanks guys!
