Hi guys. i've been working on my new system and now I'm getting down to the last few components.
here's a short list of what I have put together as of now:
i5-2500k cpu(going to oc to 4.2 probably)
8gb 1600 ripjawsx memory
Gigabyte GA-Z68-UD3H-B3 mbu
2 x seagate barracuda green 1.5tb hdd's
128 gb crucial m4 ssd
lian li k58 midtower case with 2 case fans
hyper 212 plus cpu fan
and at this point i'm planning on picking up a gtx 560 ti the next time i can catch a deal
okay so now i need to think about what psu i'm going to need. i was looking at this one:
because i was thinking i could do some sli in the future but now i'm wondering if i should just get a better quality psu with less watts for now and worry about the bigger psu later when i get a second card.
i trust the opinions around here. so what do you guys think? what size psu could i get away with? i was thinking about spending the $60 for now as far a budget.
If you (or anyone else) doesn't know that it's a good PSU, then you are taking a risk by buying it. If you know what the risks are and are happy taking them then go ahead - altho it wouldn't be what I or many other people would do.
It might say 700W on the label, but it only has two 23A 12V rails (23x12 = 276), combined they can only provide 432W. So it isn't really a 700W PSU.
A GeForce GTX 560 Ti has a graphics card power of 170 Watts. This means that the graphics card itself may draw up to 14.2 Amps from the +12 Volt rails.
For a single GeForce GTX 560 Ti graphics card system NVIDIA recommends a power supply with 500 Watts or greater with a +12 Volt continuous current rating of 30 Amps or greater and with at least two PCI Express supplementary power connectors.
For a system with two GeForce GTX 560 Ti graphics cards in 2-way SLI mode NVIDIA recommends a power supply with 650 Watts or greater with a +12 Volt continuous current rating of 44 Amps or greater and with at least four PCI Express supplementary power connectors.
The +12 Volt continuous current rating specification is vastly more important than the power supply's wattage specification.
The Raidmax Blackstone Series RX-700AC is not exactly a good quality power supply unit. The specifications for the RX-700AC do not say what the maximum combined +12 Volt continuous power output is. This tells me that Raidmax is trying to hide something. This power supply would not be capable of powering a system with two GeForce GTX 560 Ti graphics cards in 2-way SLI mode. Its lack of four PCI Express supplementary power connectors tells me that its +12 Volt DC output is weak.
thanks guys. that XFX looks nice for a power supply. never really thought about a power supply being pleasing to the eye. leaves me some room to add a future sli setup too.
The XFX will handle two GeForce GTX 560 Ti graphics cards in 2-way SLI mode since it has the four PCI Express supplementary power connectors. The Corsair doesn't have the four PCI Express supplementary power connectors.
