Which psu ?

[samm1]

hey, this is my first post here.

I've decided to purchase some parts for my PC and am unsure of what PSU would be ideal and what is recommended.

Specs after upgrade:

mobo : MSI P43-NEO-F Intel P43 Chipset 1600MHz DDR2 1066 PCI-E x16 SATAII RAI
ram : Kingston DDR2 4G(2x2G)PC8500 1066Mhz HyperX(KHX8500D2K2/4G)
gpu : Gigabyte GTX260+(216SP) SOC PCI-E2.0 896MB GDDR3 Dual-Link DVI/ HDCP/HDM
cpu :Intel CORE 2 QUAD Q9400/2.66GHz/6MB CACHE
hdd: 120 gb + 80gb
no dvd drive

current psu is 420w and came with the case but have been told that it needs to be upgraded.

Also if someone could confirm that the gpu and cpu i'm about to purchase (The only two new parts currently) will be compatible with the motherboard, as i have been told that it would work fine and a confirmation would be greatly appreciated.

Thank you in advance for any help you may provide.

What is the brand name and model number of the 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 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. Lately we've been seeing a few other brands offering some high quality units. One example would be the Antec Earthwatts and the Antec TruePower New models which are a major improvement over Antec’s older psu’s like the Basiq models.
