430W PSU Enough to power my system?

matrixninja · Feb 2, 2014

Will this PSU (http://www.newegg.com/Product/Product.aspx?Item=N82E16817139026) support my build?

Motherboard: http://www.newegg.com/Product/Product.aspx?Item=N82E16813128652

AMD Athlon X4 750K Trinity 3.4GHZ -http://www.newegg.com/Product/Product.aspx?Item=N82E16819113328

Radeon R7 260X - http://www.newegg.com/Product/Product.aspx?Item=N82E16814125480

Geil EVO Volace 4GB -http://www.newegg.com/Product/Product.aspx?Item=N82E16820144657

WD Blue 500GB -http://www.newegg.com/Product/Product.aspx?Item=N82E16822136769

This isn't the entire build, it excludes some things that don't draw much power at all. The GPU says it requires 450W, but I think that is the maximum draw.

I basically want to know if that PSU will support my build without any issues. I do have a dynex 520W PSU (http://www.bestbuy.com/site/dynex-520w-atx-cpu-power-supply/2658156.p?id=1218342638023#tab=specifications) that I can use, but I don't know how much wattage it actually provides.

babachicken · Feb 2, 2014

probably not, if you do it will be a bit of a squeeze. i would recommend atleast 500w with your build.

M0j0jojo · Feb 2, 2014

Can you get a 500Watts PSU just to be sure on the safe side? maybe one of these http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=100007657%20%20600479294%2050001550&IsNodeId=1

yes, its a nice PSu and should andle even some mild overclock for your componentes.

davcon · Feb 2, 2014

The CX430 will be fine for your gear.

dynex is crap psu dont rely on it.its on the black list http://www.eggxpert.com/forums/thread/323050.aspx Radeon R9-260X - 19A for the 12v rail and a 450W psu minimum recommended so the corsair its enough. but if planning on overclocking you better go with a better one like this http://www.newegg.com/Product/Product.aspx?Item=N82E16817438012 its 15$ more but worth the money and can power better gpu's

matrixninja · Feb 2, 2014

Thanks for the quick responses guys. However, could someone provide me a more in-depth answer? I don't really want to use the dynex, because it probably outputs the same wattage (despite it saying 520W), at less efficiency. I think it has 2 12V Rails (18A, 16A).

Thanatognomonic · Feb 2, 2014

Aslong as the PSU you get says 80+, it can either read 80+ Bronze, Silver, Gold or Platinum and it's from a reputable brand then you can be assured that it'll be giving out the correct wattage and it'll be clean power, so it'll keep your system working efficiently.

As far as I know, Dynex isn't a reputable brand and has nothing written about 80+ on its box or on the PSU itself, so I wouldn't personally use it.
Going with the Corsair CX430, like Davcon said, would be perfect, but if you feel un-sure or you want to over-clock then I'd suggest buying for a Corsair CX500 or something from Seasonic or XFX with similar wattage.

matrixninja · Feb 2, 2014

Yea, the CX430 is a Bronze level PSU. I don't trust the dynex to give out much more then the corsair, so I don't want to resort to it. Upgrading the PSU is not an option at the moment.

Thanatognomonic · Feb 2, 2014

I wouldn't trust the Dynex power supply either, from a quick review I read it says that it uses cheap capacitors and has stupidly short connectors, so your best bet really is to wait it out until you can get a new power supply..

matrixninja · Feb 2, 2014

I don't know how long it will be until I can get a new PSU. From the answers here+ some searching it sounds like it might work out. However, I would really appreciate if someone could provide an in-depth answer, as I don't know too much about PSU's.

Thanatognomonic · Feb 2, 2014

What do you want an in-depth answer about specifically?

matrixninja · Feb 2, 2014

Thanatognomonic :

Well, some of the replies are stating that it will be enough. If someone could break it down and explain why its enough (or not enough if thats the case), I'd appreciate it very much.

Thanatognomonic · Feb 2, 2014

In theory, the Corsair CX 430m would be enough to handle your system, whilst the Dynax may or may not.

The Dynax may or may not work with your system because it isn't a reputable band, reputable brands have specific tests done to test what their Power supply will give out at what % of load,
A 80+ certificate is the way of telling someone that the power supply has been properly tested and it will keep giving out 80% at least of its total wattage no matter the load. This is why we don't trust Dynax as it doesn't have a 80+ certification. Since it doesn't have one, we have no idea what % of its total wattage it will give out at what load, it could even be something like 50% at 100% load, causing it to give your system less wattage, even though in theory it should supply more.

And finally, the reason we're suggesting you should get something higher than the Corsair CX 430m is because at full load, this PSU will give out approximately 85% of its total load (I think), which may sometimes cause your system, if you've over-clocked, to not be supplied with sufficient power, causing it to shut-down or restart. If you get a higher PSU, then you can be more assured that it will give you the correct wattage constantly and it will never go below the load your system requires.

I apologise if I've written this out wrong, but it's the best I could do with what I personally know.

Here's a Dynex 400W unit that list (OPP) Over power protection as an included feature.
Snap,crackle,pop!

That feature if it's indeed included would safely shut down the psu.
Also Dynex units are energy inefficient.
Around 60% compared to the norm which is 80+ these days.

And pop goes the over-priced, non-reliant Power supply.

Thanks for the quick answer! I'm not actually planning to OC until I get a better PSU, so will it be fine unclocked (at full load, or atleast at all)?

The Corsair CX430 would work fine if you didn't over-clock anything, the Dynax, however, after Davcons video, I wouldn't trust it as far as I can throw it, wouldn't risk it one bit.

davcon · Feb 2, 2014

Yes it should be alright until you purchase a better quality unit.

matrixninja · Feb 2, 2014

When you say work fine, do you mean it will supply just enough power? Or do you mean it will be sufficient to support everything at full load?

Decent if on a budget.

matrixninja :

The Corsair CX-430m has an efficiency of 83% at full-load, which means that it'll be able to keep at least 344W at full-load, which is plenty if you don't plan on over-clocking.

matrixninja · Feb 2, 2014

Thanatognomonic :

I looked at bench marks, and it appears the card I have uses under 100W when gaming, and under 200 while bitcoin mining (which is a very intensive process if I'm not mistaken). This is based off this bench mark: http://www.tomshardware.com/reviews/radeon-r9-280x-r9-270x-r7-260x,3635-18.html

In this case, is it safe to assume the gpu will never draw above, say 250W?

Thanatognomonic · Feb 2, 2014

matrixninja :

Yes, The GPU will definitely never draw over 250w, infact I doubt it'll ever run over 150w. With the total GPU Draw of 150w, the 100w CPU total draw and about 50-100 extra for the rest of your components, You're never going to see problems with the CX 430m.

Alright, thanks for the help. So I shouldn't expect the entire power draw to exceed 350W? Is this at minimum or full load? Also, I noticed that you are saying CX430M. Its actually CX430, non modular. Does this make any performance difference?

430W PSU Enough to power my system?
