550W PSU enough for a GTX 1070?

leftisthominid · May 13, 2016

I have a Rosewill Hive 550W (http://pcpartpicker.com/part/rosewill-power-supply-hive550).

+3.3V@22A, +5V@22A, +12V@38A, -12V@0.3A, +5VSB@3A

I have a non-OCed FX 6300 with a Hyper 212 EVO on it. I am currently running a GTX 760, and I plan to upgrade to a GTX 1070.

I was wondering if my machine can run a GTX 1070?

Nobody knows. Nvidia hasn't even revealed the card TDP yet. Wait until the card is released.

But if I had to speculate, I'd guess that the should have a power draw less than or equal to your 760.

superninja12 · May 13, 2016

should be enough, however the rosewill is not the most stable powersupply.

TehPenguin · May 13, 2016

I will just go out and say YES.
Your 760 uses around 170w and the 1080 is rated at 180w. Now I know you want the 1070 but since we do not have exact specs yet I took the 1080 and one thing is certain - the 1070 will NOT be more power hungry than the 1080.

Well, there is a difference between what the power supply is capable of and what is efficient. Power supplies operate at an inverted curve, with the highest efficiency at 50% load and poor efficiency at minimal load levels and high load levels. So, if someone splurges for an 80+ Platinum power supply but runs it near its maximum load capacity, then it's all for naught. The general rule of thumb is to look at the estimated power consumption for your entire build on PC Part Picker and look for roughly double that. Also people considering adding more stuff, like a second video card, more hard drives, etc. need to factor that in as well.

However, if you just want to know if it will work, then I agree with the others that it will. As superninja said though, the stability might be an issue.

Since the GTX 1070 has been out for a while and I looking to buy one, I wanted to bump this topic to get a yes/no answer.

Since the fx draws 95 watt and the gtx 1070 is rated at 150W so essentially a 550W psu should make it but the PSU you have is not a good unit and might break when on high load. SO getting a good 650W from seasonic or evga will be a better choice. Btw fx 6300 will bottleneck the gtx 1070. So my suggestion will be to keep the GTX 760 until you save enough to buy a i5 6600k/ i7 6700k to get the best out of both the cpu and gpu.

I am not going to switch to an Intel, that would be mean getting a new mobo and thus new OS on top of the expensive prices. I may upgrade to an FX 8000-something down the road, but I am not switching socket types or to Intel. My 760 does not have enough VRAM (2GB), which is the big driver on upgrading

Your math seems off. The 760 uses more power than the 1070, and I have run it under load. I have the orignal Hive, not the downgraded Hive S.

Inkiad · Jul 28, 2016

A good 550w power supply can run most systems (99%) with a single graphics card.

TJ Hooker · Jul 28, 2016

leftisthominid :

FX-8xxx chips are mediocre gaming CPUs, and really not much of an upgrade from your current CPU. AM3+ is a dead end; I would not recommend investing any more in it. If you really don't want to change to Intel, you can wait for AMD Zen to come out, but you're better off changing sockets one way or another. If you have a non-OEM Windows license, you should be able to transfer it to the new platform.

TJ Hooker :

I am a graduate student. I don't have enough money (i.e., we don't get well paid) to build a new system, so I am not looking to upgrade anything other than my GPU right now. If it bottlenecks, I'll just have to deal with it. I would probably even stick with GTX 760 if it weren't for the limited VRAM. A few years down the line when I have a real academic job, I will build a new system, but not quite yet.

If my PSU can power a GTX 1070, I will get it.
Also, given the bottleneck, would getting a factory OC'ed model even be worth it? Would I be able to see any difference?

superninja12 · Jul 28, 2016

ocing is not worth it

leftisthominid · Jul 28, 2016

Based on some googling, I need at least 30 amps on my 12V rail for a GTX 1070, so I am presuming that my 38 amps should be good enough?

Hi - Yes, a good 550w unit will power a system with one gtx 1070. The 1070 offers 980ti performance
but uses less power.

superninja12 & Inkiad are both correct.

True the Hive might not be the most stable unit out there, but it has enough power for your
system, so go for it.

superninja12 · Jul 28, 2016

thats not how it works , the way how its done means alot. a powersupply should be bought on the stability and peformance , not by numbers.

I know how PSU's work, have not seen anything yet that shows the Hive that the OP has is
unstable or insufficient for tyhat system. If you have test results that show otherwise post them here,
because they do not appear in the realhardtechx PSU database.

In fact, the only thing that appears is (from Anandtech);
"It provides an acceptable voltage regulation and quality. We like the look more than the design from other Sirtec models, and even better is that the Hive 550W is available for about $70. That's a decent value for a good all-around PSU, which is similar to most other solutions in this performance class."

i wasnt refering to you, we posted at the same time , anyhow.
for 70 dollars (assuming the country is the usa) you can get way better units.

This is what I was trying to point out about the Hive 550W. I bought it back in early 2014, when Rosewill sold the HIVE-550 model, which was a Tier 2-b PSU. They re-released it at some point under the new name HIVE-550S, which is apparently a crappier PSU.

toyftw · Jul 28, 2016

leftisthominid :

Maybe, but the OP doesn't have the "S" version according to the specs he listed above, he has the earlier
version.

Haven't seen anything indicating the "S" series is "crappier."

leftisthominid · Jul 28, 2016

Toyft, I am the OP. I was pointing out, I have the earlier non-S version. According to the Reddit post I linked above, the S version has less reliable hardware.

The original non-S version (which I have) was Tier 2B, the S version is the Tier 3.

Got Ya! - Enjoy your gtx 1070.

Yeah, makes sense. I was just trying to say that, when you're ready for a CPU upgrade, I would go with a whole new platform rather sinking more money into AM3+ with an FX-8xxx CPU.

550W PSU enough for a GTX 1070?
