Hi all!
I've been thinking of purchasing a certain type of GTX 1070. This particular model from EVGA: http://www.evga.com/Products/Product.aspx?pn=08G-P4-6276-KR
It has two PCI-E 8 pin connections and it has a maximum power draw of 215W. The problem is that my current PSU is non-modular, and it only has 1 PCI-E 6 pin connector. This means that I will have to resort to using converters to supply the card with enough juice. I know this is generally not recommended and people have blown up their psu's by doing this... but according to my calculations, I should be more than fine. I just wanted to run it by you guys to see if I missed anything, so please point it out if I said or did anything wrong.
Now my current power supply, an OCZ StealthXStream 500W is old but it is still quite good (80+ rating, not cheap). Judging from this extensive review here (http://www.hardwaresecrets.com/ocz-stealthxstream-500-w-power-supply-review/), it is able to effectively supply 98.8% of the advertised 500W without any problems.
More importantly, it has a dual +12V rails (12V1 and 12V2) that are both able to supply 17A under full load. If my calculations are correct, it should easily be able to supply 17*12 = 204W of power on each of those rails (probably even up to 18A). My idea was to merge the connectors from 1 rails to form an 8pin PCI-E, and then the connectors from the other rail to form another 8pin PCI-E, resulting in 2x 8pin PCI-E.
So to summarize, I'll use:
6-pin PCI-E -> 8-pin PCI-E on the 12V1 rails
2 molex -> 8-pin PCI-E on the other 12V2 rails
As for the rest of my setup:
- i5 6500 with TDP at 65W
- Gigabyte D3H-B150M (? W)
- 8 gigs of DDR4 (? W)
- 1 SSD
- 1 5400 sata hdd
- a few fans from my case
Also, I am not planning on overclocking, so my CPU will draw around 65, and my GPU will generally draw around 150W of power under full load (TDP of GTX 1070 chip).
With a maximum of 485W on those dual 12V rails and a calculated 215W maximum power draw under load from GPU+CPU, I should be well within the safe range.
So why is it that people discourage the use of these converters so much? Isn't this setup perfectly fine? Perhaps there is a better solution? Please correct me if I'm wrong somewhere and let me know what you guys think.
