Question Is 500w enough for this setup ?

[LegionOfHell]

I5-6500 bclk overclocked to 4.5ghz

Gtx 970 overclocked

2x8gb ram.

I am looking at this power supply:

Is 500w enough or should i go with a cheap 700w psu like this:

Budget is 60 cdn max

If you put the pieces together in pcpartpicker.com what is your total W's for the system?

I use EVGA exclusively at this point and have 0 issues with their PSUs. If you step up a notch you can get the ones with the 10-year warranty.

I've used the Supernova / G series @ 850W for ~$100.... the prices though lately are a bit higher on the SN series which bumped me to the G option instead recently. Same functionality / warranty though and has been working well on my 12700K setup.

IMO it's better to oversize the PSU a bit to accommodate any future upgrades that might require more power to be delivered to the system. As I have an 850W that's not what it draws in its current configuration but, when I was playing around with dual GPU's it didn't skip a beat or have an issue.

If you don't think you'll ever put an RTX card into the system then you could shoot for something smaller but, there's not that big of a price difference from a 750 / 850 is $15

I would say no, 500W is not enough, not with overclocking on those parts. You might be ok without overclocking, but you are running the risk of all kinds of stability issues with overclocking on those parts with only 500W. That graphics card alone overclocked may be drawing 320-350W. The CPU overclocked could be drawing 75-90W. So just CPU and graphics cards alone you are looking possibly around 440W, and we have not even accounted for the motherboard, RAM, hard drives, fans, and lights yet.

A good PSU can span multiple generations of PCs and may easily last up to 10 years or more. It's better to invest in a good one. The eVGA product page has some good 80+ Gold models. 750W and 850W models there don't seem that expensive.

A good quality 500W should be plenty still.. even with the overclocked CPU/GPU

Picked some random other items -
376W load... i bumped the CPU up some, and overvolted.. and bumped the GTX 970 up ... added 5 fans.. an M2 SATA and a platter 7.2k RPM drive... a PCIe wireless card.. keyboard, mouse... and got the 376W load value..

GTX 970 max power draw, straight from NVIDIA as the source is 148w... even if overclocked.. you are not pulling 320-350W lol

You are stating Nvidia TDP of stock card. Stock cards have been tested to peak at 290W when monitoring with HWiNFO. These are bursts that it goes high, but these are the kinds of things that will cause a under sized power supply to struggle and go into either overdraw protection mode or drop the voltage levels in the various lines (i.e. instead of providing 12V, it will provide something like 10V or even less). All of which leads to an unstable system and possibly damaging situation as well (data corruption, system crashes, freezes, and even damage to hardware).

So, finally found someone else talking about the problem I said about GPU power usages:

At 13:12 of the video, they actually show the a post from Reddit of the "my power supply shut down once, is my computer OK" poster who posts his nonsense across 20 different tech sites every single time his computer does anything. Not the best example to use for this story, LOL.

The EVGA model supports up to 41.6 A on +12V rail, while total PSU output limited to 500W. Assuming +3.3V and +5V output is not more than 100W at full load, that would leave 400W MAX available from +12V rail which it is fully capable.

Total power consumption under full load for this entire test system using GeForce GTX 980 or overclocked GTX 970 FTW was barely higher than 300W: NVIDIA GeForce GTX 970 Review from Anandtech.

This PSU should not break a sweat outputting 400W continuously, for prolonged periods, with 100W to spare for transients. EVGA itself says the 500W model is 'approved' for GPUs up to RTX 2060 with 165W power consumption.

Exactly!
I've ran a Ryzen 3600X and RX 580 8gb gpu off a 500w previously and it never broke a sweat... never an issue...not one.

Have you tried VR with your setup?

 

[Tech Junky]

I stand behind EVGA as they have yet to have a problem compared to a couple of other options I've used in the past. PSU's are not a good place to skimp on quality / cost as it's the heart of the system.

Now, the question is whether the OP values over provisioning for a little bit more cost vs running lean with a 500W unit. The costs between different tiers is minimal until you breach 850W and then it doubles the cost. It's a sufficient middle ground for a rating and provides enough overhead to upgrade components over time as tech progresses. They stand up to whatever you throw at them within reason. I was briefly running a 8700K + 2 RX580's for mining and it never had a power issue. That setup minus all of the other parts running in a base configuration pulled 625W - https://pcpartpicker.com/list/V9zfhk

With the advent of GPU's coming out now / soon being 600W capable on their own it's worth considering the extra power now vs paying again for it later. Growing into a PSU is easier than upgrading again later. It's a PITA to be avoided if possible.

Budget is 60 cdn max

This is going to be the biggest hurdle though. Expanding the budget a bit opens the door to growing down the road.

Mining is more of a sustained workload if I'm not mistaken. That doesn't expose the transient power spike issue that might cause hiccups for a PSU. I've never mined so I'm not sure if there are spikes in mining workloads.

 

[Tech Junky]

Well, any spikes would probably be observed when kicking off the session as that's what engages the GPU's to full power. There's a lot of different issues to work around with mining though besides the HW requirements alone. I can't recall exactly all I had to change to get things stable and not have to trigger a script to reset the session. It involved quite a bit of vbios tinkering / settings changes / fan RPM mods... it just didn't end up being worthwhile w/o going to an ASIC box setup that just pounds through hashes. The mining coins didn't return more value than the cost of the electricity being used to get them. It was more of an experiment to figure out the value of passively earning coins in the background.

So how does the fact that they picked a post from online about a crash affect the fact that they captured the real issue on oscilloscope showing cards hitting 2x TDP wattage in transient spikes and showing how that causes power supplies without massive capacitors and overhead to struggle to supply the power to the card? I am still not understanding your point saying it doesn't happen, when the data is right there showing this is happening, and it is an issue and is something that people need to account for when selecting a power supply especially when overclocking components and trying to do it on a shoestring budget.... I am just failing to understand how pointing out a single item that pops up for less than 1/4 of a second in the almost 30 minutes of video and saying, that single poster who posted nonsense and thus is not a good example, and thus the whole issue must be a made up issue....

I think it's possible that he's just trolling you. He posts this on multiple forums. Waits to see who bites. Then repeats the same question in different ways until you become pissed and he gets his giggles. Who knows. He could actually be a dense non-English speaker.

You are WAY over thinking what I wrote.

I simply said the random example they chose to use was from one of the bigger tech trolls I've encountered.

I'm positive they are trolling.

There are probably a ton who do it occasionally, but then there are a few who waste so much time creating fake accounts and fake posts over years and years, that they must be very sad, lonely people. I guess if that's what "entertains" them, but to me there is so much more to life than getting your kicks with fake hardware purchase / problems.

If it takes posts like this to get a little online attention, then it's not worth it for normal people:

Just to be clear, the OP seems like a legit user, albeit a "one and done" type poster.

The poster I was calling a troll, was the one where one of their posts was shown in the Gamers Nexus video (and is the same one I linked to in the [H] Forum link).

My Intel i9-1900KS came with "Intel Inside" sticker.

I put in on front of computer case, but I installed it slightly crooked. Is my power supply OK, or should I return it? Just really worried.

I'm still lol 😅

I've met people like that in real life. You can waste hours explaining something to them. At the end, you feel pretty satisfied that you helped them out, only to find out the next day that they are bugging someone else about the same thing and wasting their time. Makes you feel crap about yourself for being dumb enough to waste your time. I think it's likely an early brain development thing. Or they were dropped on the head when little.
