a c 248 ) Power supply

The general rule of thumb is a high quality 500 to 550 watt power supply with sufficient current (amps) on the +12 volt rail(s) can easily power a system with any single video card made. A high quality 700 to 750 watt power supply with sufficient current (amps) on the +12 volt rail(s) can power a system with two video cards operating in dual mode. There are a few exceptions like the new ATI Radeon HD 5XXX series cards which use less power due to their energy efficiency.

A high quality 500 to 550 watt psu will have a +12 volt rail rated at 40 amps. A high quality 700 to 750 watt psu will have a +12 volt rail rated at 60 amps.

In addition the power supply should be at least 80+ Bronze certified for energy efficiency. There are some models available which have achieved 80+ Silver and 80+ Gold Certifications.

Before purchasing a new psu you will need to decide whether you will eventually have a pc with one or two video cards.

Corsair, PC Power & Cooling, and Seasonic are some of the 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. Lately we've been seeing a few other brands offering some high quality units. An example would be the Antec Earthwatts series which is a major improvement over Antec’s older psu’s like the Basiq models.

Thank you very much for the insight -- truly appreciate it.


For the system above, let's say on single video card setup...

The Corsair VX550!

Here's a link to a technical review of the Corsair VX550:

http://www.jonnyguru.com/modules.php?name=NDReviews&op=...

Rosewill has a reputation for low quality power supplies. They wound up on "not recommended" lists and were bashed quite a bit. They did try to make some improvements and partially succeeded. They now have a small handful of psu's that are adequate. The rest are low budget psu's of questionable performance and value.

The Rosewill in question didn't do too bad when reviewed;

Newegg has a promo code for $20 off ( ending today ) making it $50, I'd call it a good budget buy at that price.
