650W Power Supply for a build

[ToxykVib3]

I will make a this build https://goo.gl/WVdkmC with a msi z97 aniiversaty MOBO, intel i7 4790 and saphire r9 390 nitro.
I know that the power supply that I have choosen its really really bad, so I went on searching for a power supply that wasnt alot more expensive but that offered me a better quality.
PS: I intend to do some overclocking to my GPU, not a big thing, just a slightly over clock.
In my search I have found this two powe supplies both 650W the psu recommender for that GPU, and the ones I have selected are ox Hummer 650W 80+ Bronze Modular (https://goo.gl/UYqeh9) and the Corsair VS650 650W VS Series 80PLUS (http://goo.gl/3IXZqt).
I need to know wich one is the best and if they are any good.

The power supplies are not good, I wouldn't get them for powering an expensive rig.

This https://www.pcdiga.com/2/7846/Fonte-XFX-TS-650W-80PLUS-Bronze-P1-650S-NLB9 is the cheapest PSU I'd use for your build from that site. I don't know about the Hummer. The Cosair VS range are low-performance (tractor) power supplies rather than high-performance (race card) ones. you are building a high-performance (race car) computer and need an appropriate PSU.

I have the B2 650 on my oc'd 6600k (4.3ghz) and a 980ti, no problem whatsoever

But are they that bad. Or is ir just a precaution?
In some review they say that they are not thay bad, I know I should get the best but I rlt have to stay under the 1000€ mark and I have to try to save as much as I can
I I choose the hummer, would it be that really bad?
Consider that these are the only 2 options right now, is that bad or It could server my purposes?
Or I could get away with a 500W power supply wich was better? The max reported tdp for oc saphire I think is around 300w. What do you think?
And I know its not on this thread but do I rly nees the msi z97 anniversary edition mobo? Or.i could get a cheaper h97 so I could ugrade to a better psu?

I didn't say bad, I said low performance. A 450kW motor may be a bi-turbo V12 diesel for a race or sports car (Maybach), that's high performance, or it may be a turbo straight 6 diesel for a tractor or generator, that is low-performance.

Gaming systems have sudden and varying power demands and sometimes need more power than the PSU can supply from the wall, for a very short period. This extra energy is stored in the capacitors of the PSU. high-performance capacitors can handle this constantly changing load for a long time, low performance capacitors are for a constant load and fail much faster when used in a gaming system. (All capacitors fail eventually) Like chips, every PSU is different, because of the difference in their components.

I don't know enough about the Hummer. I'm assuming that it is a standard 650W Channel Well PSU, so I would not recommend it for a gaming system. (I do not know of any Bronze Channel Well PSU suitable for a gaming system sold by any vendor) I would not recommend the Corsair VS for your purpose either..

To get the best efficiency from your PSU, I would want to keep it at no more than 70% of full power. for a 500W PSU, that would be a 350W system. your overclocked system will be closer to 420W. A Seasonic 520W PSU might just do, but I would prefer one of their 620W PSUs.

Since your CPU is locked, (non-K) you could use a H97 motherboard. Why the locked i7, there may be cheaper options nearly as good (Xeon 1231v3 that I use for one)?

I know a psu don't add to performance, but a decent psu gives you a reliable power source and a piece of mind. there are better options out there that are not that expensive

 

[ToxykVib3]

What would be your choices in this price range?
Even if it was lets sau a 600w power supply

 

[DonkeyOatie]

Can you clarify what your preferred price range is?

Max 70€ its my max right now

There are ZERO PSUs on that site that cost 70 Euros or less that I would recommend for you. This is the best https://www.pcdiga.com/2/7848/Fonte-XFX-TS-550W-80PLUS-Bronze-P1-550S-XXB9 but 550W is less that I'd want to overclock a 390.

Is there another site you might buy from, perhaps they have different stock?

Int his website www.kuantokusta.pt you can search almost any store here and compare prices, maybe you can find something better

Here's what would work for me.

87 Euros http://moddingworld.pt/loja/index.php?controller=product&id_product=17999&utm_source=kuantokusta
73 Euros http://moddingworld.pt/loja/index.php?controller=product&id_product=62297&utm_source=kuantokusta should be very good.-
80 Euros http://www.kuantokusta.pt/informatica/Caixas/Fontes-de-Alimentacao/Antec-High-Current-Gamer-HCG-620W-p-1-132321

Thx 😀 I will consider those options and since I wont but the power supply right now maybe I can shave some money off to invest in a better psu as u suggestested 😀
