Which PSU would be the best upgrade?

post #1 of 22
Thread Starter 
Hey guys,
I'm looking at getting a new PSU since SLi 580s are pushing the limits of my 750W Antec PSU. Here are the ones that I'm debating:
Corsair HX1050 $200
Corsair AX850 $170
Silverstone 1000W $170

Which one of those would be the best for my needs? Thanks.

The AX850.

However, can you order from NCIX or Newegg.ca? I can't remember any other reputable Canadian retailers.

I've bought from memory express a couple times before, and the store is 15 minutes away from my house. So I have no issues with them, they'll even RMA parts for you and cover shipping during the manufacturers warranty.

Thanks for the advice +rep

All I'm really saying is that I want to shop around. However, having the store being 15 minutes away just can't be beat!

I don't mean to sound like I am doubting you or anything, but I don't know any other way to ask: how do you know your current PSU is being pushed to its limits?

I get an extremely annoying buzzing noise whenever I boot up anything that uses my 580s. And from what I've been reading then 2 580s and an OC'd i7 are just barely under 750W of power usage.

I hope this is the answer then! Plus, you could get the AX850 for a lower price than the HX850 at Memory Express! I like that.

When I price match the the silverstone and the HX850 are roughly $10 cheaper. Which would make them the cheapest in Canada.

What I mean is that they're selling the AX850 for a lower price than they're selling the HX850 because they're having a sale.

Does the buzzing noise come from the psu? Also just wondering does it happen when the rig is running stock or when the system is under load?

If its the hcp or hcg series it should be fine to run the gpu's at stock. Not sure about the EA750, is that the earthwatts?
