Power supply unit work or not

[Nurul Huda]

My pc configuration is

Processor - Intel Core i-5 2320k 3.0 ghz
Motherboard - Gigagabyte H61M - S2PV
Ram - 8 gb
HDD - 2 TB sata Western Digital
PSU - Gigabyte E570 Watt

I want to buy a new graphics card Sapphire Nitro R9 390 8gb . Will this PSU mentioned above support this graphics card ?
plz reply me asap.

Nominally a 460 watt PSU with 400 watts on the 12v rail made by FSP...

I would get a new higher quality PSU. A good 550 watt PSU would suffice.

I wouldn't risk it. As said, the '570' is some peak value the PSU will graciously output for a while and it's not the kind of extra power you'd want in your system. More like a suicide run mode.
You appear to have the right set of cables but considering the amount of system and GPU memory (Sapphire claims a 375 Watt maximum pull!), the presence of a spinner and beefy TDP on the i5 all scream 'don't do this!' to me.

Don't trust the calculators...
1: that one isn't super up to date (missing socket 1151)
2: that one says load wattage of 312 for my system and I never see it at more than 250, even with the cpu and gpu running flat out. (number measured at the wall according to the UPS)

I feel flatty is also on the fence when it comes to believing the calculator. Yup, it's just speculation.
My result with this particular calculator is similar to the one obtained by FnordMan - calculated 324, actual around 250. And we're talking a serious load. Intel Burn Test running alongside Furmark, overclocked GPU, overclocked everything, overvolted DDR, MCH, CPU...
Watts are almost meaningless. You got a glorified typewriter with integrated graphics, few fans and one module of RAM? You might get away with 300. PCIe graphics? Go for 400-450. SLI/CFX? 550-600.
I've seen 600 or so Watt OCZ PSUs failing to keep up with two 460GTX in SLI with an I5, while my old Corsair HX520 would power that rig just fine full throttle.
It's all about the quality of the delivered power. Sheer power is not enough when the PSU is struggling and overshooting/undershooting during transients or pretending to be quiet and cooking the electrolytic capacitors on the secondary after a few months of use.

The point was that according with calculator the PSU should be fine.
IF the calculator say "320" and you drawn from wall 250, is because the calculator DONT take in consideration to keep altime the PSU in full load. Because most of the PSUs having best efficiency and current quality when are loaded around 75-80%, the calculator PROBABLY consider this.

That's why a Seasonic, an Corsair or an Antec worth the money, in time that other (OCZ, Mushking etc, and to not mention obscure other brands) cant handle the wattage they are rated.

Get an XFX, EVGA, Corsair, or Seasonic unit- Anything else is subpar.

If he is drawing from the wall 250 watts, he is drawing less than 225 watts from the PSU. The calculators calculate PSU load, NOT wall load. Do some research before you spread more misinformation.

EVGA and Corsair have many mediocre PSUs, and Corsair is especially guilty of selling mediocre PSUs at near premium prices. Antec, FSP, Cooler Master, and others have their share of excellent PSUs (among mediocre and sometimes subpar ones), so blanket statements like yours does not work.

EVGA units are generally great, as are Corsair units. Look at JGURU reviews. The B series EVGA units are great for budgets as are the CX units. They get so much hate, but the company i work for has over 200 of them in daily use and there's been ONE die. That's 0.5% failure rate over 3 years.

Did I misinformed some? I briefly mentioned "wall story", I tried to point that a PSU is recommended to be loaded (on long term) around 75-80% (not keep it 100% loaded all time. Also I mentioned "PROBABLY" (in caps like now) that the calculator take this aspect in consideration. I didn't "projected" none of this calculators, by coincidence did you, to be so sure/vehement about "misinforming"?

The calculator didn't take anything into consideration. It's just a tool by retailers to try to convince people they need a larger PSU than they actually do, and isn't even maintained properly and doesn't get accurate numbers. Besides, for a typical gaming computer, sizing a PSU to target the computer's maximum theoretical load to be at 100% PSU load capacity would have the PSU working in the 50-80% range in the vast majority of gaming scenarios.

"Great for budget" = mediocre. They're mediocre PSUs, and EVGA has had a history of putting out less than good PSUs in the past. EVGA has only been getting love in the PSU department lately because they have been extremely aggressive on their pricing, but otherwise their top PSUs are in line with other top PSUs. As for Corsair, the hate comes from PSU lines like the CS, where build quality is in the mediocre range but prices are in the good to very good range of PSUs, sometimes being more expensive than Corsair's own better offerings. The best I can say about Corsair is that they haven't gone with an OEM that has put out something that was outright bad, but the CS line is something that Corsair should have never released.

so gigabyte 570 watt psu not enough for sapphire nitro r9 390 ?

 

[Tsumi]

No.

1. You may have missed it, but LGA 1151 is in there.
2. Of all the PSU calculators, that one is the closest to being accurate. IE, when it recommends 450W, most of the PSU OEM and retailer calculators recommend 600W plus. It's on the conservative side of reality, but nowhere near as conservative as other calculators.

Basically, if a person doesn't have the ability to measure/calculate their own power draw, I'm comfortable settling for THAT specific calculator, and virtually no other.

The Gigabyte Superb E570 (I'm guessing this is your PSU) is an adequate 570W PSU but not as good as the EVGA G2-550 or Corsair RM550x. So, if you were in the market for a PSU, I'd steer you towards one of those. Since you already have it...

That particular PSU has 2x 12V rails with a combined output of 34A (408W). That's not as good as the others above, but is more than adequate for all but the most demanding single-GPU systems. Also, the way the 12V rails are listed leads me to suspect that it may actually be a single-rail design (Seasonic S12-II did this as well). Also, whereas most quality 550W PSUs (like the two above) can sustain a load of 550W or even slightly higher, the Gigabyte claims to only sustain a load of 460W, not the advertised 570W.

Here's two reputable websites ([H] and Anandtech) who tested power draw. Note: This is total system power draw, and it's measured at the wall (meaning actual power draw is lower).

Power, Temperature and Fan Noise - XFX R9 390 Double Dissipation 8GB Video Card Review - 419W overclocked
The AMD Radeon R9 380X Review, Feat. ASUS STRIX - 380W was their highest reading (for the 390 used in the comparison, I know this was a 380x review)

If you assume an 85% efficient PSU in both cases, that means actual power draw for the entire system was 356W and 323W, respectively. If you plan to keep your system on 24/7, you want to aim for up to 40% over this, so 452W - 498W (450-500W as an estimate). These test systems also had CPUs that would draw as much as or more power than yours, so your total system draw is likely slightly lower.

So, I feel comfortable saying that your Gigabyte E570 is adequate for your system.

Im curious what if any Tsumi says in response, because ive never seen him oversize recommended power supplies before. Honestly hes usually the one arguing the one picked out is overkill. When he says its not enough, im inclined to agree lol.

 

[Tsumi]

FSP can be hit or miss, and without any good reviews on that particular unit (cannot even find out what the platform is), I wouldn't trust it. That is the primary reason behind my recommending a different PSU, not so much the wattage concerns.

And when there is the EVGA 500 B1 for $30 after rebates ($40 without), there isn't much of a reason to recommend something smaller. HEC built though, but quality is decent.

Valid concerns, though I haven't been able to find anywhere where it says FSP made it. I found one review of the prior Superb E550, but based on specs, the 570 seems to be a different platform possibly (actual 80+ certification this time). Still, if the 550 is anything to go off of, the 570 should be an above average 460W PSU, getting above average and within spec findings except for efficiency, where it struggled.

As I said before, if he were in the market for a PSU and looking at this one, I'd tell him to go elsewhere. But since he has it already, does he really need to replace it? Doing so would get him better efficiency, but aside from that I see no tangible benefit to a PSU swap at this time. Like I said, it should be adequate for his needs. No one here is going to be blown away.

According to Realhardtechx, the Superb 550s were Acbel Polytech, while the E570 is FSP.
