My last PSU died which was a 500, so im looking for a new one, maybe the 500w wasnt enough maybe?

Graphics : Gigabyte AMD Radeon 7870 2gb with a possible SLI later on ( adding another card )

CPU : CORE I5-3570K (6M CA, 3.40 GHZ)

Mobo : GIGABYTE GA-Z77-DS3H LGA 1155 Intel Z77 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard

Harddrive : 500 GB

SSD : plan on getting one

RAM : 8GB



I'm looking the most I can get for the least amount of money.

500W is plenty for that build. Even the best PSUs die. But the better the quality, the better they protect your OTHER components from dying with it.

That will also be sufficient for HD 7870 CrossFireX.

Five hundred watts is enough, but you need to make sure the quality is there. Seasonic does not seem able to make a bad PSU, so anything they make (their own, XFX, some Antec) would be good. Delta (some Antec) and Superflower (Rosewill Capstone) are also excellent choices.

The PSU is not the place to go cheap. A cheap low quality PSU can damage other parts when it fails. A good 500w PSU should work just fine for a system with a single 7870. For Crossfire you'd want a good 650w unit.

Must have been the cheap CX series. The secondary capacitors were cheap ones. But it is unusual that it damaged other components. They are known to die early but not known for taking other components with them.

I've suggested some above.

The tiered listing was very useful back in 2008 or so, but is based on some really obsolete data. The site above is updated more regularly.
