Hi there I have a PSU with 2 seperate- 20A PCIE rails which i plan to connect for 40A total (data sheet says 40 A total so i know they are seperate)
Has anyone done this? I find it nearly impossible to get PCIE connectors, i was going to get 2 female and 1 male but I cant find them anywhere so Im going to strip one cable and cut the other and splice them together
anyone done this?
advice? Im good with electronics so soldering etc doesnt scare me.
Not sure about this one for the fact that your trying to make something into something its not. First I'm just trying to understand what your hooking up and if this has anything to do with your hardware not being compatible?
Please explain more information about what your trying to accomplish.
"450 Watt or greater power supply with one 75W 6-pin PCI Express® power connectors recommended (600 Watt and two 6-pin connectors for ATI CrossFireX™ technology in dual mode)"
If your PSU reaches these requirments then your fine and don't need to screw with anything and if your needing to upgrade your PSU all you have to do is post your budget and Toms can find you a great PSU for the PRICE!
Maybe. Depends on if the single source feeding those rails can supply 40A. My Delta sourced Antec Earthwatts 500W PSU can handle 22A per 12V rail, but only 34 combined. Using your math it would be 44A.
The silverstone site quotes 40 A combined current available for my 560W supply
From Guru3D (i know they quote high but i have seen a lot of other review saying 30A
Recommended Power Supply
So here's my power supply recommendation:
Radeon HD 5770 (single GPU)
The card requires you to have a 500 Watt power supply unit at minimum if you use it in a high-end system. That power supply needs to have (in total accumulated) at least 40 Amps available on the +12 volts rails.
I was surprised at the 40A figure for the 5770. I know the 5750 has the power draw of the 9800GT, but with GTS250 performance. I wouldn't think the 5770 would go that much higher. 30A seems about right, and remember that's for the entire system and not just the card. Was only trying to point out that you can't just add the single rails together to get to the max output.
