Question about System Power Supplies
I am looking to get a new power supply APEVIA ATX-CW500WP4 ATX 500W Power Supply 115/ 230 V UL, CSA, TUV, CE. The main connector for this unit is a 20 +4 point connection, my current connection is a 20x1, are these two compatible? If not then could you recommend a 500W power supply that is compatible? thanks
A 20 + 4, and a 20 are industry standards. The latter for earlier mobo's and viceversa. I don't know (but I could possibly be surprised) of anyone that makes a 20 + 1....and more importantly you said 20x1 which equals 20. My suggestion is go with the 20 + 4 if for no other reason that it will come in handy when you upgrade (your old board or processor dies). As for 500w compatible power supplies check pricewatch.com....they list in price order hundreds of power supplies sold by many different companies. If unsure drop an email to one of the companies or use their free long distance numbers to make sure (I am already). One other item...500w is a lot of power...it is doubtful you need that much unless you are running a lot of equipment. There is a site on the net (and no I don't remember) but it is one of the power supply manufacturers where you can input you equipment and it calculates the wattage required. If you are a normal user, with an older board, 350w is more than enough in all probability and 450w would be enough for the foreseeable future. These manufacturers are touting 500w and up in the same fashion as disk drive mfg make bigger and bigger drives. As examples I have a 40 gb drive with 1000 songs, multiple operating systems, more software than 5 average users at least and I barely touch 18 gb. Bigger is not better...only more expensive...just ask all those soccer moms driving 80 lb kids to practice in 6000 lb vehicles at x miles per gallon at today's gas prices. Summary buy what you need with an eye on the future but (as always) the semiconductor industry goes (to the extent possible) in the opposite direction....wattage = heat, heat is no good for components, low power designs make sense....future boards, components and processors will take less power as they shrink the chip and anything beyond the current dual core processors (finally - I hated changing motherboards every few years to accommodate operating systems) will not be required by either the typical business or home user. My opinion obviously but I believe we have finally (less a truly reliable operating system) reached equilibrium. That's all (and probably too much)...have a good day...Tango
