EVGA B3 Power Supply ( PSU ) Question

I am looking to replace the current Gold PSU with EVGA B3 450W Bronze which cost around £50

Questons:
1. Can any one give a link to any B3 review?
2. Is there any better PSU in that budget? Speacialy with 5 year warrenty?
3. Is there a UK RMA centre for EVGA?

Its a old system recently upgraded. I will be pulling Aprox. 360/380 watts from Wall 4 hours everyday.

For reference:

I7 3770k @ 4.4GHz
GTX 980 Ti stock
Others Mobo rams 1xHDD 1xSSD 3xFans

Thanks in advance:)

    1. I don't believe there's any full blown reviews on the B3 yet.... but they're an efficiency improvement and update on the quality B2 platform AFAIK.
    2. Depends what kind of budget you're looking at. Can't find any for sale in the UK?
    The HX Golden Green from SuperFlower @ 69GBP is a solid option for the price.

    EVGA do appear to sell the 450W B3 for 55EUR/ 48GBP. I suspect you'd be hard pressed to better the quality for the price.

    The Corsair CX450M (not the older CX430 or CX500), is a solid deal too at 49GBP

  2. GTX 980 Ti

    Specifications
    Recommended System Power (W)** 600W or greater

    ** Recommendation is made based on PC configured with an Intel Core i7 3.2 GHz processor. Pre-built system may require less power depending on system configuration.

  3. That recommendation is to allow for the abundance of generic units of the market.

    For day-to-day use, a quality 450W PSU will be fine.

    With the OC on the CPU, and running at max load (hypothetically), a quality 450W would be borderline.

  4. With a 980 Ti you should go for a better unit, at the bare minimum at least 550w, preferably in the 650w range.
    Get either of these.

  5. OK I am happy to report as expected the B3 450W is installed and doing fine !
    The system indeed pulls 350-370 watts Gaming load from wall so 370x85 / 100 = 314.5Watts Generated
    So if the PSU everyday 4 hours generates 314.5 watts and rated to generate 450 Watts Should be fine. NO?
    Well the PSU is very well built and almost silent at load, I can hear the GFX card more! But It only has the main capacitor Japanese Not all. Cant complain at this price point speacialy when EVGA is confident enough to throw in 5 year warrenty.
    Cheers :)

  6. Under higher load that system may struggle. It will run, but that card can draw quite a large amount of power under heavy workloads.
    Just don't stress test.

    Should be fine for reasonable load....... OCing the CPU and putting greater strain on the PSU though, it's likely to struggle some when fully taxed.

  8. I'd have gone with the cx450m but its nice you've decided to test a b3 for us ;-)

    On paper they look good but I've not seen a single strip down & they appear to be outsourced & not made directly by super flower.

  9. Ya these days a lot of PSU are outsourced to help manufacturing cost.
    For test I did push the CPU&GPU to max OC with tdp and volt max possible/stable. All sliders up on afterburner. Boost to 1455MHz Mem +600 Max volt max TDP CPU at Max 4.5GHz HT. This condition was pulling 430 to 460 watts from wall Rise of Tomb Raider recived 127 @ 1080p very High. Temps reached soaring 85c. The psu ws like theres nothing! Rock Solid but gamed on for 30 min just to test

    Normaly / Personaly I dont like to stress a psu over 75% load 24/7. I am happy to game at stock. I believe these B3 lineup psu will get very popular. OVP OTP OCP etc present fully modular upto 150 watts fanless and even when it kicks in very silent. But the Big question how long it will last? Only time can say. But it does have a 5 year warrenty. If your on a £50 budget this is a Bargain at least at the moment :)

  10. Evga rate all their units as capable of running their full rated load wattage as a MINIMUM.

    Its something they have ALWAYS done .

    I have no doubt its likely capable of 500w+ but its not something I'd like to push unnecessarily form long periods of time.

    The lack of reviews & strip downs is a concern though for me personally.
