Re: Choosing Power Supply
Connectors
A current supply has a connector for motherboard 24-pin, 4-pin connector to power directly to the CPU, plus different connectors for power disk drives, optical drives and graphics cards.
The current graphics cards require connectors called PCI-Express 6 or 8-pin of their power, although adapters are supplied with maps, it is better to have good connections directly on food.
Sheathing cable or not
The cables can be sheathed or cannot be sheathed.
Sheathed cables are more practical to move into the PC, the pieces of thread are grouped together.
Modular or not
The power supplies can be modular or not.
A modular power supply allows you to connect the cables you need, it's very useful not to clutter the PC cables unnecessary.
My current Power Supply is sufficient for my new configuration?
Often, when you change a graphics card, one wonders if the power is sufficient. You should go read the label on one side of food, and we know how much power it provides, including the 12V.
On this label, you see that this power is capable of providing 14A on a 12V, and 15A on the other line 12V, its power is therefore 14A 15 A = 29A on the 12V, or 29 x 12 = 350W on 12V.
We read also below the current indications of the true power of food: Total output continuous shall not exceed 400 W: it is a 400 W continuous, not peak.
Conclusion
With these few simple rules, you should be able to choose a healthy diet for your PC.
The selection criteria should be the electrical performance (yield, stability tensions ...)
Yield:
A certified food "80 Plus" (white logo on black background) is a guarantee of good performance:
It rewards the supplies can exceed 80% efficiency over a load range from 20 to 100% of their maximum power.
New logos are beginning to appear:
These are the 80 Plus Bronze, Silver and Gold to recognize the power that can reach 82, 85 and 87% return mini between 20 and 100% load.
Some companys put the logo "82 +" for the 80 + Bronze.
Power factor correction: an active PFC power is preferable to a passive PFC.
Noise: Some PSU are even silent support, others less so ...
The best thing is to remain below 45 dB, we must avoid foods exceeding 50 dB in charge.
