I'm building a new machine around a Core i7 950 CPU, a GA-X58A-UD3R motherboard, and an ATI Radeon HD 3450 GPU or similar graphics board. I’ll start up with 3 sticks of 2 GB RAM and add more RAM later. For HD I'll probably go with the Western Digital Caviar Black 1TB. I'll also install a HP RW/DVD disc drive. All those components weigh in with a power requirement of ~450 watts. However, I'm going to buy ahead for expansion in a year or so and install a PSU in the range of 600-750 watts. I want an electrical source for this new build to include modular wiring, multiple rails, and the full complement of overage/underage protections offered inside top line power supplies.

I'd like to get as close as possible to these criteria in a price range under $100. However, I'm willing to go higher if the value is there.

Does anyone have recommendations or other comments about the best value in a power supply unit that I can find on the web?

Thanks for any and all feedback. :hello:

The XFX 750W unit is a little above the $100 mark but is modular, quite powerful, and comes with the standard protections. It has a single rail but that really doesnt affect much, its just as safe and stable as a multi rail one of the same quality would be.

Corsair and Seasonic are two brands that have a reputation for high quality power supplies that consistently earn high marks in technical reviews. They are reliable, stable, and come with a 5 year warranty. Some of the newer models come with a 7 year warranty (in the USA).

Thank you, Aneesh, Hunter and JohnnyLucky, for the recommendations. I'm definitely taking a closer look at them.

I went with the Gigabyte GeForce GTX 460. The HD 3450 was a placeholder, and, as you point out, a misfit.
This is what I finally ordered in addition to the GTX:

Chassis: Antec P183
Memory: Corsair Dominator GT 6 GB PC3-16000 2000Mhz
HD: WD VelociRaptor 300 GB
Motherboard: GA-X58A-UD5
Power Supply: Antec CP850
CPU: Core i7 950
Storage: WD Caviar Green 2 TB

What do you think? I should be able to begin assembly this week.

Thank you for that feedback. I took it to heart and switched the hard drive build to a RunCore Pro IV 128GB for the boot drive and a Samsung SpinPoint 1TB for primary storage. The velociraptor has been delivered, and I'm assuming I will send it back -- although I suppose I could add it as a secondary storage, which might be a waste of money, except perhaps to use it for all essential on-site backups.
Here's the system I'm ending up with
Graphics Card: GV-N460OC-1GB
Case: Antec P183
Memory: Corsair Dominator GT 6 GB PC3-16000 2000Mhz
Hard Drive: RunCore Pro IV 128GB 2.5" SATA Solid State Drive
Processor: Intel Core i7 950
Motherboard: Gigabyte-X58A-UD5
Power Supply: Antec CP850
Storage: Samsung SpinPoint F3EG HD103SJ 1TB
Fans: Thermal SpinQ VT

???=WD VelociRaptor 300 GB
