Missing Items in New TX850M PSU from Amazon

Hello

 

I am a new member looking for some assistance

 

I have just purchased a brand new TX850M PSU from Amazon for a new build, however, when checking the items in the box I am missing the EPS ATX 12V Cable 8Pin - 4+4 required for my Ryzen 5800x CPU and Tomahawk X570, I am also missing the bag for the cables (although this is not a big issue), the manual clearly states these items should be supplied, the box was sealed.

 

Can anyone help please, is this normal to have missing items now and again or am I just unlucky?

 

Was considering sending back and getting another, but if a bad batch I could be back to square 1.

 

Would very much appreciate your help

 

Edit, On having a look at the manual again I think it may be misleading, it lists an 8 pin - 4+4 cable, but I think this is integrated into the PSU.

 

Can you get a cable to fit this, or am I better changing psu?

The 4+4-pin cable is fixed. Not modular.

 

There's also no cable bag. Never was.

 

See here: https://www.tomshardware.com/reviews/corsair-tx750m-psu,5062.html

 

Why can't you use the fixed 4+4? Why do you "need" a modular one?

Sorry I was not completely clear in my post, long day yesterday :bigeyes: perhaps I should elaborate.

 

Yes it has the 8 pin cable, integrated along side the 24 pin board power, and it does fit the 8 pin CPU PWR1 header, however my query was regarding the additional 4 pin header on the board CPU PWR2. It looked as if there should have been an additional 4+4 CPU cable with the power supply.

 

The modular sockets on the psu are marked for a 4+4 CPU cable (image2) you would naturally assume that if a 4+4 modular CPU socket is on the PSU there should be a cable to fit it??

 

The manual states that a "DC Modular cable storage bag" should be included within the package contents (Image1), this is not an issue but added to my confusion somewhat.

 

From my research last night it appears CPU PWR2 is not required to be connected unless doing extreme overclocking, but this flies in the face of the msi x570 manual as it asks for this 4 pin header to be connected from the psu unit.

 

Has been a few years since I have built a system, and my last board did not have the 4 pin cpu power on it.

 

So...back to my query

 

Does CPU PWR2 on the board need to be connected with a 5800x CPU?

 

If it does, do all 8pin to 4+4 CPU modular cables have the same pin outs, can you just buy one from any supplier, or does it need to be a specific cable?

 

This one looks suitable

What you will need though is those two 8 pin connectors for your videocard if you have anything somewhat mid to high end. GPUs will need the power.

 

I have a Vega64 Sapphire Nitro +

 

The PSU is supplied with 2 x Type 4 PCIE power cables, each which split into 2 x 6/8 pin connectors on a single lead.

 

I thought each Type 4 could supply 300w (150w x 2) from a single cable, leaving the other 8 pin header on the PSU available for CPU2 or another GPU in the case of SLI.

Ah i didn't know it came with pigtail cables. Never used these but you must be right.

 

But even then, if you ever fancied to overclock your CPU it would pull at worst 170 - 180W.

The 8 pin connector can supply almost twice that. even a badly overclocked 10900k doesn't need the extra 4 pin.
