250 Watt Dell PSU

[rapty]

Im in a bit of a Pickle at the moment and unsure of Dell PSUs normally I would replace the bloody thing but I need to be back in England in the comeing Days and dont want to wait for a PSU to Install for a freind, I have Ordered a P5B Board, e6300, 1GB of DDR Ram, SCSI HD, Sata HD, Evga 7600 GT, CD RW & Floppy Drive

The Specifications of the PSU :

Model : NPS 250KB

5v line 22amps
12v 14amps
5vsb 2amps

-12v 1amps
3.3v 18amps

if i understand you correctly......you want to use a dell psu on the stuff your ordered? if that is the case then no.............the psu will not be enough and IIRC dell likes to use their own psu's wich means it may or may not have a standard 20pin connection.

What Rail would be Overloaded?

What Rail would be Overloaded?

The +12V rail. Modern systems suck up so much juice from the +12V rail. Also, modern motherboards strongly recommend, if not require, a native 24-pin ATX connection from the PSU to the motherboard. The old Dell PSU is likely not compliant to the ATX specification due to the different pin assignments on its ATX-style connector - and using that Dell unmodified will likely burn out your new motherboard.

The incompatible Dell PSU's were made several years ago, since then all Dell PSU's have been compatible with the ATX 20pin connector.

Plus, if I've interpreted correctly, Dell PSU's tend to be underrated compared to other brands. For instace, a 250watt Dell, may be comparable to a 350 watt X PSU. But I maybe be mistaken on that.

Fair enough. However, the motherboard of a modern platform like a C2D or an x2 CPU still strongly recommends the use of a native 24-pin ATX connector (or a modular 20+4 pin ATX connector with the extra 4 pins still attached to the rest of the connector) over a 20-pin ATX connector that's been adapted to 24-pin with an adapter.

And as I said, those 14A on the +12V rail isn't enough for a C2D with any decent PCI-Express graphics card, regardless of the quality of the PSU.
