if your PSU blows out due to overload, will it ruin your other components? i'm going to buy a 1000w PSU today because my 500w PSU was stressed from overclocking my i5-3570k and r7770s in crossfire (cocky i know). i'm just wondering if i'll have any component problems after i get the new PSU. .

PSU failure certainly can damage components.

Make sure to get a quality PSU from a reliable manufacturer.
Corsair, XFX, Antec, Seasonic, Rosewill are such brands.

A shady 1000w PSU can fail if it's internals aren't quality.

The poorer the quality of the power supply the more likely it is to damage other components when it fails. Here's a decent guide on whats good and what should be avoided.

Agreed but you still have to be careful with Rosewill while they have some good ones they have a couple bad ones aswell. I would rank them close to Coolermaster on that front.

I always put them in the end of my lists for reliable PSU manufacturers :p 
The rest of them are pretty equal, so they get a random order depending on which one comes up in my mind first :p 

Personally, I always go with Seasonic, or Corsair when I'm on a more limited budget.

All XFX PSUs, and many Corsair AX series PSUs are manufactured by Seasonic :)

Just a note re. Rosewill: Their CAPSTONE series is built by Super Flower and has a 5 year warranty. The HIVE is built, as best I can determine, by Sirtec (Sirfa/highpower) and has a 3 year warranty. Don't know about the rest of the line.

Hard to go wrong with Seasonic, Corsair, XFX, or Antec.

Coolmax power supplies are absolute crap they are a tier 5 unit and should be avoided at all costs. Look at the eggxpert link in my first post and stay away from anything in tier 4 and especially tier 5.

what about this one? i have a z77 extreme4, an i5-3570k (4300 MHz), 8GB DDR3 RAM, 1TB 7200 RPM and two r7770s. do you think 750w will be enough? http://www.microcenter.com/product/406089/CX_Series_CX7...

well, it occurred when i was watching a movie; nothing too strenuous there. it just shut off and it wouldn't turn back on. there was no burning smell or anything. i just suspected that it died or something.

750w is more than enough for 2 7770's. Corsairs CX line are thier budget line middle of the road type units not great but not bad either. Whats your budget and does it have to be from microcenter?

Cheap improperly designed power supplies will damage attached components when they die.

For a system using two Radeon HD 7770 graphics cards in 2-way CrossFireX mode AMD specifies a minimum of a 600 Watt or greater system power supply. The power supply should also have a maximum combined +12 Volt continuous current rating of 30 Amps or greater and have at least two 6-pin PCI Express supplementary power connectors.

You underpowered your system configuration with that 500 Watt PSU so of course it died of over stress.

Get a reputable name brand 650 Watt PSU with 53 Amps or more capacity on its combined +12V rails. At least it will safely handle your overclocking.

this one isn't necessarily 650w, but it's a reputable name brand. i checked the specs, and it says "+12@62A." i'm guessing that's over 53 amps. here's the link: http://www.microcenter.com/product/406089/CX_Series_CX7...

They really don't have a good selection of PSU manufacturers at Microcenter...

yeah, i looked at that one. i'm not sure that that is enough wattage.


Yes the Antec High Current Gamer 620W is a good PSU. It's based on Seasonic's M12II Bronze 620W platform. Its 48 Amp +12V continuous current rating should also be fine for your system configuration.

If you don't mind rebates

is this one more reliable than the one i suggested? i'm guessing it is, but for assurance. i need to make sure i'm getting my money's worth.


The TX uses higher quality components and as such has a 5yr warranty vs the cx's 3yr. That said either one will work for your rig. If you are set on a 750w unit they do have the TX750 for $115 ($105 after rebate), but its not modular.

This one is also good. It is based on a detuned (i.e. reduced by 20 Watts) version of the Seasonic's M12II Bronze 620W platform. It also has a 5 Year warranty.

This PSU is equally good, for cheaper and free shipping.
If you can wait for it to get to you ;)
