Hi Everyone,

Just on the final stretch of my new build - only need to buy the SSD boot drive and PSU before putting the PC into the new case.

Anyway, I just have a couple of questions. The main one being, is there a massive difference in terms of quality between the Corsair HX850i and the EVGA SuperNova 850 P2 and T2? If the differences are marginal, which would you opt for and why?

The other question that I have is regarding SSDs. I will be buying a PCI-E SSD as a boot drive. I felt settled on the Samsung 950 Pro 512GB, but have seen Intels 600p 512GB SSD and I'm just wondering if there will be a massive difference that I will experience in terms of speed for general computing? My games will be on the SATA SSD until such time as I want to buy another PCI-E SSD.

Thanks in advance :)

The EVGA SuperNOVA 850 T2 is the higher efficiency rated PSU, and the P2 is pretty much the same performance-wise; however, if you are like me and leave your pc on 24/7 then it wouldn't make much difference which one you choose because they both will draw about the same electricity. The Corsair will give you the same output as the P2 so I would go with whichever is cheapest as they are all pretty much the same PSU when it comes down to it. The T2 could be more useful if you are using more than two graphics cards, I mean the P2 could support two GPU's if they run less than 300W.

For any more info on the T2, and P2 see:

The easy way is to read up on the specs of the Samsung 950 and Intel offerings.

Compare the read and write through put speed of both.
And see if one or the other also has data cache, or a memory buffer incorporated on the NV stick Alex.
If it does quote either stick as cache, or memory buffer features check what size the buffer or cache size is.
The larger in size the better.

Some sticks have it others don`t just like desktop SSD drives.
Examples are a Kingston V300 SSD drive with no buffer or cache.

Vs a Samsung 850 SSD drive with 512Mb of Dram cache memory fitted gives a better sustained read and write speed Alex.

Hi thanks for for your help and input, guys.

I have decided to go with the Samsung Evo 960 as it's an M.2 drive and that will run on 4 PCI-e lanes on my mobo (X99 ASUS Strix ROG).

Also, I decided to go with the Corsair. They seem to be roughly the same products in terms of quality, and they all have 10-year warranties. The primary reason I have opted for a corsair PSU though is for ease of management - I have a h100i liquid cooler which runs off Corsair Link, and so will the HX850 or RX860.

Once again, I do that you for your help. This is the first time that I have had to look at PCI-e lanes and PSU; I was really quite ignorant (probably still am, to be honest) as to how variable PSU models are and how pci-e lanes are assigned.
