 Techist - Tech Forum Reading A PSU

Can someone explain some of those values to me, as I do not understand what any of that means and I would wish to learn the meaning of those values. Thanks, Ted __________________ __________________

In this case there are 2 adding up to a total of 44Amps which is very nice. And the wattage is up to 620 which is very good aswell. You basically want to buy a power supply with 450 and above watts and around 25Amps and above. __________________ __________________

Like there is 597.8 W under part of the values and 22.2 W under other values, adding up to 620 W all together. Also I was wondering what active and passive PFC is. I think it is something that changes the incoming electricity to the right level or something so the computer doesn't get damaged, not exactly sure though. __________________

You can get a 600W or 700W and their around the same price as that Enermax. OCZ is a quality brand like Enermax too so you can trust them. 600W: http://www.newegg.com/Product/Produc...82E16817341001 700W: http://www.newegg.com/Product/Produc...82E16817341002 i have the 600W and its awsome. like the corruptin advertisement of McDonalds says "I'm Lovin it" O yea, they also have blue LEDs too if you like those __________________ *Opteron 165 1.8Ghz *DFI Lanparty UT nF4 Ultra-D *HIS Hightech X1900XT 512MB w/ Zalman VF900 (Core: 690Mhz, Mem: 1500Mhz) *G.Skill 1GB DDR 400 *Kingwin Mutant X Series *HP IDE Lightscribe DVD Burner *Seagate Barracuda 80GB SATA II *Maxtor 80GB IDE *OCZ Gamexstream 600W PSU

I know it says it has SLI support but how come it doesn't have the SLI logo thing? __________________

That might also hold you over if/when we ever see quad SLI/CF support, stuff like that. __________________ *Opteron 165 1.8Ghz *DFI Lanparty UT nF4 Ultra-D *HIS Hightech X1900XT 512MB w/ Zalman VF900 (Core: 690Mhz, Mem: 1500Mhz) *G.Skill 1GB DDR 400 *Kingwin Mutant X Series *HP IDE Lightscribe DVD Burner *Seagate Barracuda 80GB SATA II *Maxtor 80GB IDE *OCZ Gamexstream 600W PSU
