    Question PSU Recommendation/Advice?

    Hey guys,

    I'm currently in the process of spec'ing out my next PC which I'll be buying/building next month and I'd really appreciate some advice on what PSU to get (figured this is the best place to ask for recommendations).

    CPU: AMD Ryzen 5 2600 3.4Ghz
    Motherboard: ASRock B450M PRO4 Micro ATX
    Memory/RAM: Corsair Vengeance LPX 16GB (2 x 8GB) DDR4-3000
    HDD: Western Digital Caviar Blue 1TB 3.5" 7200RPM
    SSD: Kingston A400 240GB 2.5"
    GPU: Zotac GeForce GTX 1070 8GB Mini Video Card
    Case: Aerocool Aero-500 RGB (2x120mm fans + case fan controller)
    Power Supply: SeaSonic S12II 520W 80+ Bronze (this is the PSU I was originally looking at, but from what I've read it's pretty dated and doesn't stand up well to current build quality?)

    Location: England, UK
    Budget: Preferably 50 or under
    Overclock: Not planning to overclock any time in the near future

    I haven't got a preference on merchant, happy to buy from wherever has the best price.

    Thanks!

    That's not much of a budget.

    Corsair CX450?

    60 seems like a more realistic price.

    Unfortunately not on this one; I'm working to a 400 budget on the CPU, Mobo, RAM, PSU, HDD and Case

    Is there a significant difference between CX450 & CX450M PSUs?

    Could probably stretch 10 higher if it gets me a considerably better PSU! There's a chance one of the other components might drop a bit or I could alternatively look at a slightly cheaper case (Versa H17).

    Is 450w more than enough for the planned build? PCPartpicker had it at an estimated 320w, so I figured anything north of 500w would provide enough headroom with an 80+ Bronze rating.

    Any thoughts on the following:
    Antec NeoEco 550w
    EVGA Bronze 500w (B1)
    Be Quiet! Pure Power 11 500w

    Yes the CX series use a better and more modern LLC resonant converter design instead of the double forward converter of the CXM series.

    In that case get the Bitfenix Formula Gold 450W, it's a nobrainer.

    The average power consumption while gaming is around 200W and the peak power should be less then 250W a high-end 300W PSU with the right connectors should already be enough, but such a PSU doesn't exist.
    That Antec and EVGA should be avoided for a modern PC, they are based on old design. The be quiet is better, but you don't need the 500W version and it isn't as good as the BitFenix, nothing is for 60.

    With that Budget, a good quality 300W would be fine. Sadly that is something that just doesn't exist.

    The Bitfenix is worth it, its just so much better...

    80plus Rating is irrelevant.
    The only correlation between 80plus and Quality is that its almost impossible to make a good quality bronze PSU that's cheaper than 80plus Gold is hard to do. So most people just don't...

    Thanks again for the advice, really appreciate the info in the replies!

    I was going to go with the BitFenix as suggested, but I can only find it in stock at Overclockers and the delivery takes it over 70 (as I haven't posted enough on their forums to qualify for free delivery). That hits the budget a bit harder than I'd like in all honesty.

    Out of the following 3, which would be the next best and offer good value for money?
    - Corsair CX450 450W 80+ Bronze (45)
    - SeaSonic S12II 520W 80+ Bronze (51)
    - Be Quiet! Pure Power 11 500W 80+ Gold (55)

    Alternatively, is there anything in the sub-65 range on Ebay.co.uk that anyone could recommend? There's a discount code for 10/15% off which might be useful.

    Cheers!

    I wouldn't buy a PSU off eBay. T-shirt or audio CD, sure.. PSU? No.

    Sorry, should've probably clarified that I don't mean a used/refurbished PSU; I'm still looking to buy a brand new unit from a reputable seller. Some retailers sell through Ebay as well and as Ebay are offering a discount code of 10/15% on electronics, I was hoping there might be something else on there!

    Probably wishful thinking on my part, but I'm just trying to make the most of savings without compromising significantly on quality components.

    I'm looking at the Ebay 15% offer today too. Scan, Ebuyer, CCL Online, Box, Currys/PC World etc all have Ebay stores where they sell new with full warranty.

    Here are links to some PSU listings:
    CCL: https://www.ebay.co.uk/sch/Power-Sup..._BIN=1&_sop=15
    Ebuyer: https://www.ebay.co.uk/sch/Power-Sup...uk_ltd&_sop=15
    Scan: https://www.ebay.co.uk/sch/Power-Sup...rs_int&_sop=15

    I'm not knowledgeable enough to point out what is good so I'll leave that to someone else. Here are links to some that have been mentioned:
    CORSAIR CX450 42.49 w/discount https://www.ebay.co.uk/itm/CORSAIR-C...IAAOSwkDtcP8zC
    Be Quiet! Pure Power 11 500w 50.67 w/discount https://www.ebay.co.uk/itm/Be-Quiet-...AAAOSwoAFcOGs3
    Be Quiet! Pure Power 11 400W 46.60 w/discount https://www.ebay.co.uk/itm/Be-Quiet-...4AAOSwteFb2G4V

    Maybe this?
    Corsair TX550M 58.79 w/discount https://www.ebay.co.uk/itm/Corsair-T...IAAOSwtfhYtVvl
