Should I swap KL600M for CXM650M?

Morning all,

I recently purchased the below system build from OcUK and it should be arriving today but I am slightly concerned about the PSU.
Upon calling OcUK for an update on Monday (11th business day since ordering the system) I was informed it failed the stress test due to a faulty PSU. Now after seeing what PSU they provided, assuming this is the same model as the one that failed, I am not feeling overly confident about it.

I have a Corsair CXM650M I bought 1 year ago that I've been using in my current system and was wondering if you all recommend swapping out the Kolink KL600M for it.
It's an unwanted hassle to have to redo the cable management of brand new build, as I don't trust using other brands power cables on other brands PSU but could be better for the machine itself.

I tried to research the Kolink KL series online but there are no reviews about other than OCuK staff + Kolink staff pushing it on these forums and people moaning about them on TomsHardware etc and the odd Amazon review. The fact it failed in testing does not fill me with confidence.

Kolink KL-600M 600W 80 Plus Bronze Modular Power Supply
Phanteks Eclipse P350X Glass Digital RGB Midi Tower Case
**Build Promo**Intel Core i7-9700K 3.6GHz
System Build Fan - Noiseblocker BlackSilent Pro Fan PLPS - 120mm PWM x2
Gigabyte GeForce RTX 2080 Gaming OC 8192MB GDDR6 PCI-Express Graphics Card 1
Gigabyte 256GB M.2 PCIe x2 NVMe SSD/Solid State Drive 1
Samsung 500GB 860 EVO SSD 2.5" SATA 6Gbps 64 Layer 3D V-NAND Solid State Drive (MZ-76E500B/EU) 1
Asetek Premium Retention Kit Intel LGA115X
Gigabyte Z390 UD Intel Z390 (Socket 1151) DDR4 ATX Motherboard 1
Corsair Vengeance LPX 16GB (2x8GB) DDR4 PC4-24000C16 3000MHz Dual Channel Kit
 
After a bit more research I can see the max load on the +12V rail for the Kolink KL600M is 480W whereas the CX650M is 648W.
Bit of a difference that the Corsair can deliver near max load on the 12V rail as opposed to the Kolink that delivers 120W less than its max load.

I think I will swap it out after all even though it is extra work to recable all the work just done to it.

Opinions still welcome.
 
I'll probably invest in a new PSU later in the year, this is mainly just to get me up and running.
As I said earlier, the fact the OCuK guy said the PSU failed in testing does not fill me with confidence and after reading reviews of people having Kolinks dying after short amounts of time.

Rather use my CXM650M for 6 months - 1 year then upgrade it to a gold standard PSU.

I presume it cost considerably more than that with the gpu upgrade and extra SSD? That is just shocking that they put such a cheap and nasty sub standard psu in a pre-built that must be coming on for £2000 with your changes. There's pushing a product because your parent company is behind it and then there is just pure and simple skimping to maximise profit. Utterly disgraceful. We in the forums are always trying to get the message across that the psu shouldn't be skimped on and is not the place to save money and they go and use that in a expensive build. I would have expected a quality Gold rated Seasonic, Antec or at the very least a Gold rated Bitfenix Formula series in a build such as that.

It cost ~£1700 inc postage.

FYI first thing I did after unboxing yesterday was swap the PSU out.
The cabling isn't as tidy as they did it due to my Corsair cables being different but I feel more confident in the stability.
I also changed out the standard case fan for an Akasa Viper and kept the 2 static pressure fans on the radiator. The stock case fan is quiet enough but I'd rather have more CFM on the exhaust if needed. I could always sway it back if it bugs me.

I'll invest in a gold rated PSU in a few months.
