We have purchase many of these power supplies (about 33) of them and only 1 has been defective.
These are TRUE 400-watt ATX power supply units. They are well constructed (we disassembled one),
are heavy (about 6-7 pounds), and can support most motherboards (about 90 per cent). They come
with most modern connectors including a PCI-e 6 pin connector, a 12 volt 4 pin motherboard connector,
a 24-pin main board connector which includes a 24- to 20 pin adapter for older motherboards.

These power supplies can even accomadate some of the newer more powerful motherboard 8 pin 12volt
connector (just insert the 4pin into the 8 pin slot of the motherboard that will fit it - its failsafe against
plugging it in incorrectly). The only motherboard (that we tested) that will NOT power up with this power
supply was a ASUS P4T533-R and the ASUS P4T533-232. These motherboards require a minimum
of 550 watts to power up and use the old RAMBUS interface (184 pin and the 232 pin Rambus Memory
Modules). Also, if you use a 140 Watt CPU, it will most likely fail to power up the Mobo. We tried
4 of these CPU's (AMD Athlon II and Phenom II) and only 1 powered up of the 4. Otherwise, it
will easily power up a 45 watt to 125 watt CPU.

I've got two computers I've put this Dynex power supply into and I love the results. Souped-up speed and they're super quiet. I can always find one of these guys at a good price too. Good, stable parts at a good price. I wish all parts were this cost-effective and high-quality.

It's a perfect fit for a Dell XPS 400 without having to modify the tower casing. Installation is simple. Cables are ample length and possibly too long, but that's not a drawback. It's extremely powerful and runs very quietly if you keep your heat well and fan casing clean. Great buy!
