QuestionPower supply Dynex 520 takes a few minutes to turn onI just replaced my power supply on my desktop is a Amd quad core with a Sata drive msi motherboard. After putting the power supply in, it didn't work right away. I rechecked and replugged power to motherboard and waited. After a few minutes it went on. It works fine now, but if I power off my tower and shut off my power surge it doesn't power up again. Then I have to open the tower again and wait few minutes. Do I have a defect power supply or does the computer have to stay on all the time? I just purchased at best buy 2 day ago?

- Answer I have had no issues like that but it sounds more like something is discharging the capacitors on the motherboard which would cause a delay because it has to recharge the board before it can power up. That is lime 30-40 seconds usually.

QuestionDoes this power supply work with intel pentium d cpu's?A while ago I upgraded my dell dimension e520 from a intel dual core 1.83 Ghz to an intel pentium d 930 3.00 Ghz cpu. However, the model compatibility states that it works with dual-core and multicore CPUs. Would it still work with the cpu I currently have?

QuestionCan this be used in dell 531s inspironI need to replace my psu in the dell inspiron 521s model
Asked 13 years ago by Anonymous.
- Answer I believe the tower takes a standard power supply so close to anything should work. If anything take the unit to Geek Squad and an Agent can take a look for you. I would like to also mention if you have not changed anything on the unit your watt requirement should still be on the power supply you have in the tower.
  I would recommend:
  - Dynex™ - 520W ATX CPU Power Supply - Gray

  - Dynex™ - 400-Watt ATX CPU Power Supply - White

Questionwhat is this unit peak amperage?Can this unit power a PNY Nvidia GTX 550 Ti, at high speed?
Asked 13 years ago by Anonymous.
- Answer I would go with something with a little higher continuous power rating. The continuous rating on this is around 440 watts. I'm too lazy to take the side cover off my system to check it right now, but in my Gigabyte P43 system I have a 650 watt continuous supply. The quad-core Intel CPU uses 130 watts by itself. John
