Need help wth Buying a PSU

Platinum Era · Jul 30, 2013

Currenlty I have a Corsair AX860 (860 watts to future proof, might be overkill) but I am going to return it because it emits coil whine (Repurchasing the same PSU prooved useless since the 3[I retuned 2, using 1 to power my system temporarily] that I got and returned all had the same lot number). The shipping cost to RMA my PSU is too much (20-30$) and I don't want to gamble on getting one without coil whine. So I'm playing on getting a replacment buy I can't decide which one to get so I've come to you guys for help. I have till Thursday, maybe Friday

If I do decide the keep my current PSU, would the coil whine damage or reduce the lifespan of the PSU?

* = update on decision

*So far I like: http://www.futureshop.ca/en-CA/product/thermaltake-thermaltake-smart-850w-power-supply-sp-850m-w0414ru/10207856.aspx?path=7a281763ff9093d533300dcd5a7b9a4een02&SearchPageIndex=1 and http://www.bestbuy.ca/en-CA/product/antec-antec-high-current-gamer-900w-power-supply-hcg-900-hcg-900/10187679.aspx?path=c98b65521ee0f586b50b675e7aec0626en02&SearchPageIndex=1 but I'm still open to discussion

Guidelines are:
- The PSU MUST be purchased from futureshop.ca/bestbuy.ca (I would have loved to get it anywhere else but I have to use the gift card I have)
- 80 Plus Bronze minimum
- Try not to go over 200$ (I can easily price match it)
- Little headroom for overclocking, SLI (maybe, I prefer going single GPU) in the future and to ultimately future proof my system as much as I can.
- Semi-Modular at least

The PSU will be powering (i'm just going to list some of my specs):
Asus Z87-A
i5-4670k
1 EVGA GTX 770 SC with ACX (maybe 2 in the future)
1 Kingston SSD
1 WD 1TB Blue Drive
1 random LG disc drive
All in a Cooler Master CM690 II Advanced case (I have room to hide wires since I removed a large part of the harddrive bays if it isn't modular at all but I would prefer it is)

Thanks guys!

Manufactured by either Seasonic or FSP.

Have you tried talking to Corsair Customer Service directly: I have had to use them a few times and they are extremely helpful and competent. (I am assuming you have been dealing with your retailer).

for a start you dont need 860w psu. 550w will be more than enough for that build. because of that you can get a much better but lower power psu. such as a http://www.bestbuy.ca/en-CA/product/antec-antec-earthwatts-green-650w-power-supply-ea650green-ea650green/10190134.aspx?path=7b55d51feb4ef19715db06c0c027a1bden02&SearchPageIndex=1

its a 650w by antec

Yes I have spoken with Corsair and unfortunately I have to pay the shipping charge and since I'm in Canada, Bestbuy.com is not an option Bestbuy.ca is

O.k., heres a nice Antec, it is online only if that matters, but they are made by Delta; arguably the best psu manufacture out there.

A little less money and a little less power:

The 900Watter will definately power 2 GTX770's.
The 750 watt unit might:The information I found says it has 4 12v rails with 40amps per rail. That's a helluva lot of power.

The 770 requires 42 amps and the antec only has 40 or am I wrong? http://store.antec.com/Product/power_supply-high_current_gamer/hcg-900/0-761345-23890-8.aspx
I know a fair bit about Pcs and components but not much for PSUs

A while back in history, multi rail PSUs had some isssues with enough power on the rails.
The name brands (Corsair, Seasonic, XFX, PC Power&Cooling, enermax, ANTEC) have engineered those problems away: That 900 watt unit will provide more then enough power for your system, even with two 770's. Simply stated, not necessarily engineering accurate, the 12V rails will switch power from underused rails to overused rails to provide the needed power.
I don't know if it actually can produce 160amps on the 12 circuit (4X40), but I would bet it could produce close to 100.
[ ko888 or SR-71 Blackbird, if you read this, a little help please ]

Thanks for the brief history lesson but I did research after and found the amps per rail, thank you either way.

I think it was 70.8 per rail, I'm not too sure
