Antec TruePower New TP-550 550W Continuous Power ATX12V V2.3 / EPS12V V2.91 SLI Certified CrossFire Ready 80 PLUS BRONZE Certified Active PFC "compatible with Core i7/Core i5" Power Supply

Pros: Many SATA and Molex connectors if you intend to fill an Antec 300 or 900 with drives.
If you mount the PSU "upside down" with the fan up, the Antec logo on the visible side is right side up.
Decent combo price with Antec 900 case.
120mm fan is quiet.

Cons: I wish the 8 pin ETX and 4 pin ATX motherboard connectors were module. I only use the 4 pin, so the 8 pin is just tied up in the bottom of the case.

The SATA connectors are oriented so that starting from the PSU, the first connector should be the top most drive. I wish this was the opposite for bottom mounted PSU cases.

Overall Review: This has many connectors for connecting many SATA and IDE drives. Permanent direct connections include:
1 x 20+4 Motherboard
1 x FDD
3 x Molex
3 x SATA
1 x 6+2 PCIe
1 x 4 pin ATX 12V
1 x 8 pin EPS 12V

Up to 4 of the following can be connected:
1 additional 4 pin PCI-E
SATA cable each with 3 SATA connectors, 2 cables included
Molex cable each with 3 molex connectors, 2 cables included

If you only use 1 PCI-E connector, a maximum of 9 SATA drives and 9 IDE drives can be connected without using any splitters (as long +5V and +12V long are not exceeded).

Pros: its a good brand and has a good warranty and is 80 plus bronze

Cons: First was DOA sent it in to be replaced and second one died less than six months

Overall Review: products i have bought from Antec have been good some better than others, but this is really disappointing and has cost me an additional $20 for the shipping.
