hi, just ordered this psu,as my old coollermaster 600w psu only had two 18a rails. will this be ok,as i got it cheap.
 
It's a bit late to ask for advice after you have already bought it. It's a no frills cheap and nasty budget psu built by HEC. It will do the job but you would have been advised to spend more and buy something decent.

Why didn't you just connect each of the GTX780's 8/6pin connectors to separate rails?

i read on the forums that i would need 42 amps for the gtx 780.
my coolmaster only as 36 amps combined, 18 amps on each rail. i could still cancel the psu ive ordered.

I may be losing the plot here but AFAIK 42A at 12V is over 500W, I thought the GTX780 only had a 250W TDP.

Personally I would find out what cables are connected to which rails and work out the loadings that can be put on each cable, but if you're not confident doing that then it's prob easier to just drop in a single rail PSU.

Do you know what model number your CM 600W PSU is? I could prob take a look at the specs and tell you.
 
When I had a EVGA GTX780 FTW in this pc albeit with a 4670k clocked to 4.4Ghz my peak power draw for the whole system was just under 400w at the wall but only by running furmark and linx both at the same time. Normal gaming peaked at anything up to 322w depending on the game. GPU manufacturers always overstate psu requirements due to people skimping on the psu and buying garbage. Which model Coolermaster do you have? Going by a 600w total capacity with a pair of weak 12v rails is it a Extreme Power Plus? If it is then that's a terrible psu and would need replacing anyway although you would be better off replacing it with a decent quality psu.

yes its an old Extreme Power Plus its been in my sons sandy bridge pc for around 8 years, will that Evga psu be ok,hes only going to be using one gtx 780 an an overclocked i5 2500k at 4.2 ghz
 
Like I said, it will do the job but it is a rather poor choice. Cheap and psu do not go well together. The psu is argueably the single most important component in a pc and is not the place to skimp. Buy a good quality psu and it will last many years. That is not a good quality psu.

It's so cheap because it's so bad. Gutter quality power supply from EVGA. If I were EVGA I would ditch W and B lines because they are PSU cancer as far as I'm concerned. They sully EVGA's reputation IMO.

That's my rant (with apologies) and I'm sticking to it. Please don't take a terrible terrible PSU and put that much load on it. It's just not wise.

If you want to use a junk PSU put just a hair of load on it (like a pentium with IGPU).

No, that's more cheap and nasty rubbish and even worse than the CX series which never gets recommended on here due to cheap internals.

The cheapest psu's on here that I would be happy to use myself are these:-

A extra tenner get's you a very good gold rated fully modular psu:-
