PSU requirement with added WC loop

[Scoob]

Hi,

My 2nd topic here today

I currently have the rig in my spec below (gamer) which has an HX750 PSU. This PSU seems to be working admirably, though I'm aware that 750w is considered border-line for what I'm running.

Now, I will shortly be water cooling this PC, so adding an Alhpacool D5, two 360 rads (80mm), a CPU and two GPU blocks as well as 6 fans. My question is - am I pushing it with the 750w PSU? I know my PSU is "a good 'un" in that it's from a major brand that doesn't skimp on performance, but I'm still concerned I'm asking for trouble especially as I overclock.

For the record, my current PSU performed fine when my CPU was at 4.6ghz (and higher for a bit) and my GPU's at 850. However, getting to these levels again - now it'll be cool and quiet - might be a push with just 750w and the pump & fans added.

Just after peoples thoughts here.

Cheers,

Scoob.

you're fine dude lol two 570's = 575W + O.C. Cpu/mobo = 700W/725W lol.. a HX750 does up to 845W under load at least mine does corsair powersupplys are underrated push it doubt it'll break

Hi Lauralarry,

Yeah, the pure numbers suggest I'm pushing it but based on the reading I've done the HX750 is over-spec'd compared to many. I know with my current setup the PSU fan has never even ramped up even during stress-testing so I assume it's well within limits and not being stressed at all.

I think I will stick with my HX750 and only if I encounter problems consider upgrading it.

Cheers,

Scoob.

or your psu fans is broken.

Lol, no, I don't think so. Fan is spinning just fine but never ramps up. Nor does the air coming from the PSU get noticably warmer when the PC is stress-tested. Other PSU's I've been able to notice such things.

Could you let me know if you have any problems? Quite interested in this as a friend has a similar setup
