Need a PSU for a 1070

[alca]

Are there any good ~$60 PSUs that are good enough to power a 1070? I'm on a budget so around $60 would be great.

Whisper M 450W or Formula Gold 450W. If those are not available, the Focus Gold 450W or TX550M, but those are louder. 

Why a 1070, though? Usually, the 1070 Ti costs only a bit more, and you gain 25% performance.

Has OPP/OTP problems. Read the link in my sig for more info.

I would say that any 500w PSU with a 35A (or more) 12v rail would fit the bill.

I was thinking a CX-M 550W for $89.99 CAD?

Oh, you are in Canada?

Been seing only good things about MasterWatt PSUs (not Lite ones, though).

I'm in Toronto, so I don't think there's memex nearby. Thanks.

Like this 1600W 90+ Gold PSU? It says 120,5A on the 12V rail.

Is that a 500w PSU?  No, no it is not.

The aforementioned Seasonic Focus Gold, Cooler Master MasterWatt and EVGA G3 would all work fine. 450W is plenty unless you have something like a 6950X or 1920X for a CPU.

Ah, so it has to be exactly 500W. Otherwise it won't work. 

 

The point, however, seems to have gone right above your head. So to make it clear. 

You can't recommend a PSU based solely on how many amps it claims on the 12V rail. 

Also, having just 420W on the 12V rail of a 500W PSU would mean the PSU is absolute crap. Lots of absolute crap 500W PSUs provide more than 420W on the 12V rail.

I would get a Corsair CX550M, personally. A Seasonic Focus Gold in the 500-550W range will work as well.

Yeah, deciding between CX550M & MasterWatt 550. I'll see, ty!

$100, and $120. The MasterWatt is the only one in budget

Thanks a lot for the info! Now I am really glad that I picked up a G1+. I was kind of bummed because G3 was out of stock when I bought a PSU.

Absolute garbage 500w PSUs have like, 28A on the 12v rail and something stupid like 35A on the 5v rail.
 

Also, those "garbage" 500w units with 400-450w on the 12v rail will power a GTX 1070 + i7 without much issue.  Spending $90 on a 500w PSU is borderline insane, unless its a specialty form-factor.

Seasonic Focus Gold. Not Focus Plus Gold.

If a 500w PSU cannot do 40+ Amps 12V then it's garbage

An ATX PSU is not a 12v PSU, so the 12v rail will only ever hit 40A+ on overspeced garbage that costs about 50-100% more than it should.

 

A decent quality 500w 12v only PSU (with functioning OCP, OVP, and OPP) can be had for $30, and regulation for 5v and 3.3v is trivial to implement on a 12v only base unit, maybe $20. so what are you paying that extra $40-$60 for?  A name brand?

All good modern ATX PSUs are 12V units with 12V -> 3.3/5V VRMs, if the PSU cannot do near full wattage on the 12V if uses a group regulation topology -> it's shit...

Naa, because those are garbage.

You want a 500W PSU with at least 40A on +12V, 45A for a 550W.

Or rather: Close to 100%.

Yes it is, these days!
Just look at how they are built.

 

You have 5V Standby and +12V Isolated Power, the +5V and 3,3V are generated out of the  +12V Rail via Buck Converters.

 

As for Rail Distribution:

Most of the powerdemand of modern Components is +12V and nothing else. There is very little that does NOT use 12V. And that is only because the ATX Connector is made to be +5V Heavy and only has two +12V Cables on it.

so that only leaves Stuff on the Motherboard...

So with 500W Power Consumption its very likely that we talk about 480W on +12V and only 20W - if not less than that - that isn't on +12V...

Yeah and? For how long? Will they die within 3 Years?

Those 500W PSU with 400-450W on +12V are ancient group regulated units that might go out of spec with load due to construction. 

And what if the good quality 90€ PSU can prolong the lifetime to 6 Years? Or more. 

You just didn't know what you were talking about, people called you out for your ancient knowledge and now you try to justify what you said with the bullshit claim that it will run??

What you were saying was OK back in 2010 or earlier. And you stuck with it, without looking at the changes in PSU Technologys. The poblem is:
In the last 10 Years there was more stuff happening in PSU Technology than in the 10 years before that. Because the usual design used in old AT Power Supplys from the 90s stayed with us up until the mid 2000s, sometimes even the late 2000s. But today you won't see those from reputable manufacturers. As for Efficiency. We are talking about ~90% between 20-100% Load. Those things you are talking about had an efficiency of 80%, maybe 85% or less.
 

Yes, this PSU also did run a PC a week ago: 

 

So according to you, it must have been fine, right?

Because if it runs, its fine. That is what you were saying...

If you don't know what you are talking about, then don't talk about it. Easy as that. If you made a mistake, own it and say that you didn't know better. Nobody will be angry at you for not knowing. However not knowing and claiming to know is a different thing. THAT is what people will be angry about.

 

As for what you are claiming:
a) do those PSU have fans? Fans can be from shit = 50 Cents or less to really good wich means 20€ or more.

b) How is the Efficiency of those Units?? Are we talking about around 90% in 230VAC? With the +5V/3,3V Regulators??
c) What about Warranty? Do those have Warranty? And what are we talking about?? A Year or two?? ATX PSU have, at worst, 3 Years right now and 5 Years are rather common.

d) How much amperate 3,3V/5V are we talking about? Right now ~20A is the Standard, while some only have 15A, others go up to 25A.

 

I really hate that "Paying for the Brand" claim. That's just nonsense that came from some people who have little knowledge about pricing of a product - or never talked with people who do that...
