Are 500w enough for r5 5600 and rtx 4070

My psu is high power hpq-500st-h12s. What are you thinking? Do you think it is enough? And will there be a bottleneck in 2k (low-medium-high-ultra)? I guess not at ultra settings but I don't know about low settings.
 
Of course not. I would go for 650 w gold at minimum.
 
The system would pull at most 350W, should be fine, how many watts does the PSU have on the 12V rail?

It depends on the rest of your configuration. If you have a basic MB, 2 stick of RAM, 1-2 storage device, no RGB, ... it should be fine. In the contrary, a high end MB, 4 sticks of RAM, 4-6 storage device with lot of RGB, it will be at the limit of what the PSU is capable of (in the 450-500W total)
 
The wattage is fine. The quality isn't. If you honestly want to ensure a problem free experience, buy a higher quality 5-550w unit and relegate your current PSU as your test/back up unit. That's all it's useful for IMO.

This is bad advice in my opinion, if you buy a new PSU might as well get one that is considerably higher wattage.
 
5600 seems to draw ~160W (whole system) at max and 4070 at ~230W
I've checked your PSU and the 12V only gives 450W at max, there isn't much headroom but it should hold as long as the quality is good

That really depends on how expensive they are where the OP lives. A good 550W unit will power a wide arrange of systems, even a 4080 if you undervolt it. A PSU that can handle any GPU (including spikes) will cost substansially more than a solid 550-650W unit.
 
It may do fine until heavy loads, but surely would cave in at transients.
Definitely size up, and take something higher tier, like Seasonic Gold unit or any of its rebrands
 
I would look into power optimizing this system to make sure that the cpu or gfx doesn't go mad with power all suddenly.

No. Bad advice is telling him that his current PSU is fine because his system should only pull 350 watts. Not taking into consideration the quality of the PS? Hmmm.

He can buy a solid 500-550w unit for $75-$100. If he bumps that to a quality 650-750w unit, the price jumps significantly.
The fact that he bought a $50 tater in the first place should've been a tipoff towards potential budget constraints.
 
if specs don't lie it should be fine

The wattages his system pulls will still be well below what that PSU is rated on the 12V rail, what I said is factual, the quality of the PSU is irrelevant, worst that can happen is the protections are triggered. You can have a PSU rated for 850W that is also of poor quality, how exactly would the quality be relevant in that context if I take it into account ? You're going to assume that it is the same, better, worse, how do you evaluate this lol.

Contrary to popular belief most cheap PSUs are absolutely fine when not pushed to their limits, if they were the fire hazards people seems to believe they are millions of them wouldn't be sold every year.

The quality of the PSU is irrelevant? That has to be one of the most ignorant statements I've ever seen. And it says everything anyone needs to know about your um, level of expertise.

Believing your own made up bs is one thing, spreading your bs to new members is just sad.

To the question of “is this PSU enough”? Yes dude, it literally is irrelevant, all that’s relevant to that question is the wattage, OP didn’t ask “is this PSU good quality”. You’re the ignorant one here for going off a tangent. I told you even a 850w PSU could be of bad quality, is that PSU enough or not ? This is so stupid.

No, it's not.
500W high quality PSU could be able to handle loads that 500W low quality PSU could not, due to higher 12V capacity alone, nevermind transient response/DC regulation itself.

I feel like I’m repeating myself nonstop, the system in question will pull 350w at most and the transients are going to be well below what the PSU is rated for.

For both a “good” or “bad” PSU the transients can still trigger the protection, this is why I said it’s absolutely pointless to buy a higher quality PSU that’s the same wattage. You’ll just run into the same issues, this shouldn’t be solved by buying a better PSU and hoping it can “handle the load better” at the same wattage. Talk about lack of expertise.
 
You guys are funny. I suggest reading the reviews on the site you are posting. TPU review of the 4070 saw a maximum draw of 200w. That leaves another 250w for the rest of the system. 5600 will pull around 165w. Suggested psu requirements are always inflated.

Do you have reviews of this PSUs confirming that? Its markedly lower 12V capacity vs total suggests it's not DC-DC based, and hence likely an entry level unit that might not actually be able to handle those loads well.

Do you have a review confirming that it’s not going to be enough ? Lol

The wattage math checks out, it should be enough, that’s all that it is relevant for the question in the OP.

Okay, then I will take no-name "500W" junk with maybe 200W combined 12V capacity, slap 1200W label on it, and according to your logic THEN it will be enough too. :rolleyes:

The problem is that GPU and CPU aren't the only thing that draw prower. If OP have a lot of storage device and 4 RAM stick, he could be in trouble with his PSU. It have no certification and are a cheap model so it can't be able to manage his system at full load if he got a lot of small other thing in his pc.

This is so stupid I am honestly stumped.

This does not have 200w, someone posted the specs above read them, it’s 450w on 12v rail which is enough.

I’ve wasted enough time on this, OP can do what he wants.
