Corsair PSU/SMPS okay?

Boy07 · Dec 7, 2016

Many said my poor PSU might be responsible for performance and kill pc components/peripherals.
My RIG : MSI gtx 1060 6GB(400W req.), i7-4790(3.6 Ghz), Gigabyte b85 mobo, Corsair vengeance 8 gb DDR3 ram,Corsair VS550W PSU ,Toshiba 500gb(7200 rpm)
So,do I need to change PSU?

your PSU will not cause poor performance, instability yes, failure yes, but not performance.

13thmonkey :

Will it damage my pc components/peripherals,or by failure you mean it will die at an early stage?Its not clear by what you try to mean instability and failure.

13thmonkey · Dec 7, 2016

Poor performance = low frame rates etc. A PSU cannot cause this.
Instability = random crashes, blue screens etc.
Failure = PSU fails, it may take other components with it.

These are generally 'what can happen' to a system, a PSU will only cause the bottom two, (other things can also cause the 2nd item).

Whether your PSU is bad enough I can't say, but if you are having performance issues the PSU is not the cause.

13thmonkey :

My concern is will it damage pc hardware or have any risks.Or should it be just fine?

13thmonkey · Dec 7, 2016

A good PSU can fail, a bad PSU is more likely to fail.
A good PSU is more likely to fail safely, a bad PSU is more likely to fail unsafely.

It's a tier 4 PSU on this list, http://www.tomshardware.co.uk/forum/id-2547993/psu-tier-list.html?_ga=1.164108474.40728491.1363025293

Which means it's not great, keep it lightly loaded and you'll be OK, but when it fails it may not be graceful.

13thmonkey :

My graphics card requires 400 W power supply.So that load is probably okay?And what about voltage,I exactly don't know.You can check my rig mentioned in the beginning.

13thmonkey · Dec 7, 2016

I think you'll be fine, but it's not a great supply, it says it can do 480W on 12V rails, that's a good sign of an attempt at quality. There are poor 550W supplies that won't do 250W on the 12 V rail.

Boy07 · Dec 7, 2016

13thmonkey :

I expect truth in words from Corsair.It may fail,thats pretty normal at a stage,but hope wont damage my rig.And you mean other 'poor 550W' supplies are actually 250W instead 550W?

13thmonkey · Dec 7, 2016

a good PSU will be able to deliver most of it's power over the 12V rails, something like 90-95% of it, simply because this is how most of the power gets consumed, so if your rig is consuming 300W, it's probably consuming 270+watts off the 12V rail.

Therefore if a PSU claims to be 550W but can only provide 250W on the 12V rail, the question should be asked 'is it really a 550W PSU', and the answer is no, as it can't provide 500+watts of 12V rail power which is where most of it would be used.

In your case it can do 48x12=480W, which is OK, not great, not poor.

It has various protections:
• A dedicated single +12V rail offers maximum compatibility with the latest components.
• Active Power Factor Correction (PFC) with PF value of 0.99.
• AC input from 200~240VAV.
• Over-voltage, under-voltage, over-current, and short circuit protection provide maximum safety for your critical system components.
• High-quality capacitors provide uncompromised performance and reliability.
• A three year warranty and lifetime access to Corsair's legendary technical support and customer service.
• Safety Approvals: cTUVus, CE, CB, FCC Class B, TÜV, CCC, C-tick.
• Conforms to ATX12V v2.31 standard, and is backward compatible with the ATX12V 2.2 and ATX12V 2.01 standards.

So it's OK, it may not be as 'sturdy' as other PSU's but it ticks most boxes.

I can't say it is a wonderful PSU and you'll be happy for the next decade, I can say it's OK.

This site : http://www.hardwareinsights.com/wp/corsair-vs450-review/4/ says it has low quality CapXon capacitors,contrary to what mentioned on Corsair's website.And this thing is not clear to me "Voltage regulation could be better",does this affect/damage other components?

13thmonkey · Dec 7, 2016

you need to understand the difference between marketing and the truth, there might be 2 high quality capacitors and the rest are rubbish. If the regulation is inside specification for ATX then you'll be fine.

Ultimately though it is your decision, in a hot environment, with poor stability on your mains, i'd prefer something else myself perhaps. Will it fail, no idea, would it be a waste of money to get a new PSU, i'd say not, a good one will last you for your next 3 builds.

Only while playing games,I have noticed the PSU is getting hot.Warm air is circulated.Is this normal?

Yes, normal, again a bad PSU will be rated at 30c, good ones at 40 or 50c.

Can the info(corsair website) be relied upon?And are CapXon capacitors really bad as many threads say?

13thmonkey · Dec 8, 2016

Yes for actual facts, marketing speak is marketing speak, so vague statements like 'high quality capacitors!' may just mean 2, it might mean all of them.

CapXon, no idea, if reviewers don't like them, then i'd trust that, if a thread doesn't like them then i'd possibly ignore that until I got to someone that knows what they are talking about.

Boy07 · Dec 8, 2016

13thmonkey :

As you have got the summary info about VS550W,so there would not be performance issue,right?Even with those capacitors,only lifespan would be short..As of now no blue screens,no crashes!

13thmonkey · Dec 8, 2016

Look, this is the third time now that I've said that a PSU will not cause performance issues, it will only cause instability or outright failure.

Boy07 · Dec 10, 2016

13thmonkey :

48x12=as u said 480 earlier, there's a doubt.So less power

13thmonkey · Dec 10, 2016

what is your point?

Boy07 · Dec 12, 2016

13thmonkey :

As you said earlier " In your case it can do 48x12=480W, which is OK, not great, not poor. ",the product of multiplication...

13thmonkey · Dec 12, 2016

You obviously are not comfortable with your PSU, so buy a better one, if 'In your case it can do 48x12=480W, which is OK, not great, not poor.' isn't good enough for you then you need to take action to make yourself happy.

Boy07 · Dec 12, 2016

13thmonkey :

48*12=? 480!!!!

13thmonkey · Dec 12, 2016

you are going to have to actually use words and make a point, or i'm leaving this thread to founder.

WHAT IS YOUR POINT? It's an OK PSU, not great, not poor. a poor PSU would have around 250W (for a 550W PSU) and great PSU would have maybe 520W.

Boy07 · Dec 12, 2016

13thmonkey :

48 multiplied by 12 equals 480!I didn't get that,and there's no need for leaving this thread,why should you,you shouldn't leave to founder.No need,not at all
