What makes a good PSU? - Page 2

post #11 of 19
I aim for efficiency, too- Forgot that one

Higher efficiency can be equated to "what you put in is what you get out"...It will never be 100% efficient, but close to that is nice

Brand name can point you int he right direction, but I would never buy a PSU (or anything) just because of the brand name. If the specs were good, and the reviews backed up the specs, then it could say FORD on it and I would buy it.

Strong rail(s), high efficency, active PFC, and if you can find ripple tests on it check those out.

Most was covered that is important.
Active PFC
Rail amperages
effency %

Oh, and wether the cables meet the needs of the equipment!

The one thing that is most deceptive, the "Watt" rating!

Yeah, even the most reliable PSU can blow out shortly after install. It's a good idea to run a GPU/CPU burnin app for 24-48 hours after turning on your new PSU. Be prepared to return it.

For instance, I have an Enermax model which had a notorious failure rate and it's been running my folding rig 24/7 for months with no issues. You can never tell.

There are many different factors you want to look at to determine what make one PSU better than another. There is the most obvious and usually the most relied on category of wattage. Wattage is important and is often used as the main way of choosing the proper PSU. It doesn't take a genius to determine what wattage they need for thier rig, just add up the total wattage used by your system. Now Amprage is definately more important than wattage, you may have enough watts but without the amps you won't even get a signal to your monitor. There really isn't any REAL quality difference between multi or single +12v rails, some say that more rails = stability but the best PSU manufacturer only sells single rail PSU. So after amps and watts are figured out you will want to seek out a quality manufacturer. Never settle for a cheap no name PSU always spend the extra cash to get a good reliable PSU. What makes one better than the other really come down to internal component quality. As it is near impossible to determine this you are just better off choosing a brand with a good reputation.
