  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing

Dell Dimension E520 Power Supply Question

Asked by andrepires in General Computer Systems

Tags: e520, dell, power, supply, dimension

Hi experts!
I have a Dell Dimension E520 with a burnt power supply. The power supply model is H305N-00.
The technical specification of the power supply is:

+5V = 22A
+3.3V = 17A
+12VA = 18A
+12VB = 18A
-12V = 1A
+5Vfp = 2A

Connectors:
24Pin Motherboard and CPU Connector
4 x 5Pin SATA Power Connectors
1 x 4Pin IDE Power Connector
1 Floppy drive power connector

Max Output Power: 305W

As I said, this power supply is burnt and it is very difficult to find an original replacement here in Brazil, so I'm trying to find a generic power supply with same specifications.
I found one with the following specifications:

+5V = 50A
+3.3V = 32A
+12VA = 19A
+12VB = 19A
-12V = 1A
+5Vsb = 2A

Connectors:
24Pin Motherboard and CPU Connector
1 x 5Pin SATA Power Connector
5 x 4Pin IDE Power Connectora
1 Floppy drive power connector

Max Output Power: 550W

My questions are:

1) The generic power supply has only one 5Pin SATA Power Connector. The vendor said that I can use
IDE to SATA power adaptors, but this is what I'm worried about... The SATA Adaptors have only 4 wires
(Orange-Black-Red-Black), while the SATA power connectors in my original power supply have 5 wires
(Orange-Black-Red-Black-White)... What is the white wire for? Can I really use the adaptors and the
new power supply?
2) It seams like the generic power supply is technically superior if compared to the original one.
Does it represent a problem for my computer or it is ok?

Thank you very much!
