psu Choosing a PSU for heavy use

[Newbie0]

Hi all,

It’s been a few years since I completed my build.  But sadly I had to RMA my V750(burnt cables). So now I’ve to choose a new one. 
 

So far I’ve narrowed down my choices to 4 PSUs. 
 

SEASONIC PX 750

Be-Quiet Straight Power 11(5 year warranty)

Corsair RM750x

CM V750(2019)

 

In these PSUs (almost) all of them has a 10 year warranty. One of them is even Platinum PSU(Seasonic). 
 

I’ve a bit experience about CM support & they were great for me. I don’t know about others though. 
 

[My system will be running for around 18/7 for heavy gaming.]

So which one should I choose from these?

 

Thanks all. 
 

Edit:

System specs:

R5 1600x

2x Sapphire Nitro+ RX 580 4gb

MSI Tomahawk B350

WD Green 128gb SSD

Toshiba 1 TB HDD

Toshiba 500GB HDD

Seasonic is the top of the line in PSU's

[Beerzerker]

Specs on the system it's to be used with would be most helpful here.

It's hard to suggest something for a setup you don't know anything about.

[Fasauceome]

corsair's warranty support is remarkable, and their RMX units are pretty outstanding overall. 

 

although I don't think you'd be disappointed with any of these selections

I would go for a Be Quiet Straight Power 11.

Excellent quiet PSU.

 

I feel like it's a step above the others, which are about as good as each other.

Of course knowing you system specs will help in accurately estimating what would be your best option.

This is the halo effect. Just because a certain brand has made excellent products, doesn't mean their products are always excellent.

Unless your comment was saying "This specific Seasonic PSU is the best out of the bunch", which I did not get that impression from your post.

If your PSU failed and you RMA'd it then Cooler Master is sending you a replacement unit, correct? Why not use that?

Was it one of the older series on V750 power supplies or was it one of the new series?

Which cable melted? Where did it melt? What was it plugged in to? Have any photos?

Thanks. But I was trying to avoid that one(for higher price )

[boggy77]

from that list the straight power is the best. you can look at bitfenix whisper as well, as they are very good and cheap

You can go for the 550W version of any of these PSU's too.

My recommendation still goes to the Be Quiet Straight Power

 

Misread the double RX 580 part

I was told that I’d get a replacement. But got refund as the seller didn't  have that in stock. 
it was one of the older series. 
 

At first GPU. Then CPU. At last Mobo. All of these was at the PSUs end.

Thanks. But Seasonic one is platinum. Isn’t that better than the be quiet?

Given the system spec. I need a 750w PSU. The Corsair one is 10$ extra from every PSU. 
 

Is the WARRANTY SUPPORT of Be quiet good?

Less expensive than the PX though

 

But the rig you specified in the original post only draws like 450 watts, so maybe Consider a cheaper model?

For 2x rx580? That's tight.

 

@Newbie0

How did you connect the cards with the V750? I assume it's the pcie-cable that got burnt?

Ah, at least they were able to give you a refund. Does the refund you got cover the cost of the PSUs you are looking at or are they more expensive?

 

It's odd that all of those different cables melted on the PSU side... Not sure why that would be.

It just means it's [slightly] more efficient.
There's also a new be Quiet Straight Power 11 80+ Platinum unit that was just released as well.

So the Straight Power is better than the others. Right?

With 8+6 pcie cables.

Yes.

Oh, you have 2 580's. Yeah, 750W is a good choice in that case.

My experience with Be Quiet's support has been positive in the past, but I have never used it for PSU's (only for one of their fans once).

Efficiency is good, but components on the inside matter a lot too. Plus it's also very possible one is just barely a Platinum while the other is barely not a Platinum.

Efficiency is not something to base your choice of.

 

The Be Quiet is a high quality very quiet PSU.

Missed the part about the dual 580's.

Might have missed it but it's listed as 2x RX 580's in their specs, not just one. Looking at about 200-ish watts per card, plus the other stuff.
In addition to how much power it draws I believe those Sapphire Nitro+ cards require 2 PCIe connectors each, meaning they would need at least 4x PCIe connectors from the PSU, which many of the 550W PSUs don't have.

750W makes sense here.

All of the PSus you listed are good.

[Sir0Tek]

Yes. 

That is not what I was looking for. It has 4x PCIe connectors, I guess it is 2x on 2 cables?

Well, the GPUs only require 1 pcie connector (psu end) each. 

[Juular]

First of all, new CM V-series are meh. Second, be quiet! unit are multi-rail which is a plus (especially with multi-GPU setups). Other than that, they're pretty much identical when it comes to performance and quality, so maybe be quiet! SP11 for multi-rail then, although it has 5y warranty so if that matters for you i'd probably suggest Corsair RMx then.

Yeah, missed that part. After OP and @Sir0Tek pointed it out I edited my comment. You must have quoted me before this edit was made.

But thanks to all for being so watchful

 

My previous RX 580 card required only a single 6+2 pin PCIe though and it used about 200W of power under full load.
